Class II elements (or DNA TRANSPOSABLE ELEMENTS - such as transposons, Tn elements, insertion sequence elements and mobile gene cassettes of bacterial integrons) transpose directly from one site in the DNA to another.

Effect of a staphylococcin on Neisseria gonorrhoeae. (1/3560)

Phage group 2 staphylococcal strain UT0002 contains a large 56S virulence plasmid with genes that code for both exfoliative toxin and a specific staphylococcin termed Bac R(1). Four penicillinase-producing strains and three penicillin-susceptible strains of Neisseria gonorrhoeae were killed by Bac R(1). After 30 min of growth of the penicillin-resistant TR1 strain in 62.5 arbitrary units of Bac R(1) per ml, loss of viability was approximately 90%, and, after 5 h, an approximately 99.99% loss of viability was observed. Lysis did not accompany cell death, and 84% of the Bac R(1) added to the growth medium was adsorbed to the gonococcal cells. The extracellular supernatant fluid from a substrain of staphylococcal strain UT0002 cured of the plasmid for Bac R(1) production had no lethal effect on the gonococcal strains. Bac R(1) was also shown to have bactericidal activity against an L-form of N. meningitidis, indicating that the outer envelope of a neisserial cell is not needed for bacteriocin activity. Ten different normal human sera were unable to neutralize Bac R(1) activity. The bacteriocin lacks adsorption specificity. It binds to but does not kill Escherichia coli cells, indicating that the cell envelope of gram-negative organisms can provide protection against the staphylococcin.  (+info)

Prodigious substrate specificity of AAC(6')-APH(2"), an aminoglycoside antibiotic resistance determinant in enterococci and staphylococci. (2/3560)

BACKGROUND: High-level gentamicin resistance in enterococci and staphylococci is conferred by AAC(6')-APH(2"), an enzyme with 6'-N-acetyltransferase and 2"-O-phosphotransferase activities. The presence of this enzyme in pathogenic gram-positive bacteria prevents the successful use of gentamicin C and most other aminoglycosides as therapeutic agents. RESULTS: In an effort to understand the mechanism of aminoglycoside modification, we expressed AAC(6')-APH(2") in Bacillus subtilis. The purified enzyme is monomeric with a molecular mass of 57 kDa and displays both the expected aminoglycoside N-acetyltransferase and O-phosphotransferase activities. Structure-function analysis with various aminoglycosides substrates reveals an enzyme with broad specificity in both enzymatic activities, accounting for AAC(6')-APH(2")'s dramatic negative impact on clinical aminoglycoside therapy. Both lividomycin A and paromomycin, aminoglycosides lacking a 6'-amino group, were acetylated by AAC(6')-APH(2"). The infrared spectrum of the product of paromomycin acetylation yielded a signal consistent with O-acetylation. Mass spectral and nuclear magnetic resonance analysis of the products of neomycin phosphorylation indicated that phosphoryl transfer occurred primarily at the 3'-OH of the 6-aminohexose ring A, and that some diphosphorylated material was also present with phosphates at the 3'-OH and the 3"'-OH of ring D, both unprecedented observations for this enzyme. Furthermore, the phosphorylation site of lividomycin A was determined to be the 5"-OH of the pentose ring C. CONCLUSIONS: The bifunctional AAC(6')-APH(2") has the capacity to inactivate virtually all clinically important aminoglycosides through N- and O-acetylation and phosphorylation of hydroxyl groups. The extremely broad substrate specificity of this enzyme will impact on future development of aminoglycosides and presents a significant challenge for antibiotic design.  (+info)

The staphylococcal transferrin-binding protein is a cell wall glyceraldehyde-3-phosphate dehydrogenase. (3/3560)

Staphylococcus aureus and Staphylococcus epidermidis possess a 42-kDa cell wall transferrin-binding protein (Tpn) which is involved in the acquisition of transferrin-bound iron. To characterize this protein further, cell wall fractions were subjected to two-dimensional sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis blotted, and the N-terminus of Tpn was sequenced. Comparison of the first 20 amino acid residues of Tpn with the protein databases revealed a high degree of homology to the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Analysis of staphylococcal cell wall fractions for GAPDH activity confirmed the presence of a functional enzyme which, like Tpn, is regulated by the availability of iron in the growth medium. To determine whether Tpn is responsible for this GAPDH activity, it was affinity purified with NAD+ agarose. Both S. epidermidis and S. aureus Tpn catalyzed the conversion of glyceraldehyde-3-phosphate to 1,3-diphosphoglycerate. In contrast, Staphylococcus saprophyticus, which lacks a Tpn, has no cell wall-associated GAPDH activity. Native polyacrylamide gel electrophoresis of the affinity-purified Tpn revealed that it was present in the cell wall as a tetramer, consistent with the structures of all known cytoplasmic GAPDHs. Furthermore, the affinity-purified Tpn retained its ability to bind human transferrin both in its native tetrameric and SDS-denatured monomeric forms. Apart from interacting with human transferrin, Tpn, in common with the group A streptococcal cell wall GAPDH, binds human plasmin. Tpn-bound plasmin is enzymatically active and therefore may contribute to the ability of staphylococci to penetrate tissues during infections. These studies demonstrate that the staphylococcal transferrin receptor protein, Tpn, is a multifunctional cell wall GAPDH.  (+info)

Molecular characterization of the nitrite-reducing system of Staphylococcus carnosus. (4/3560)

Characterization of a nitrite reductase-negative Staphylococcus carnosus Tn917 mutant led to the identification of the nir operon, which encodes NirBD, the dissimilatory NADH-dependent nitrite reductase; SirA, the putative oxidase and chelatase, and SirB, the uroporphyrinogen III methylase, both of which are necessary for biosynthesis of the siroheme prosthetic group; and NirR, which revealed no convincing similarity to proteins with known functions. We suggest that NirR is essential for nir promoter activity. In the absence of NirR, a weak promoter upstream of sirA seems to drive transcription of sirA, nirB, nirD, and sirB in the stationary-growth phase. In primer extension experiments one predominant and several weaker transcription start sites were identified in the nir promoter region. Northern blot analyses indicated that anaerobiosis and nitrite are induction factors of the nir operon: cells grown aerobically with nitrite revealed small amounts of full-length transcript whereas cells grown anaerobically with or without nitrite showed large amounts of full-length transcript. Although a transcript is detectable, no nitrite reduction occurs in cells grown aerobically with nitrite, indicating an additional oxygen-controlled step at the level of translation, enzyme folding, assembly, or insertion of prosthetic groups. The nitrite-reducing activity expressed during anaerobiosis is switched off reversibly when the oxygen tension increases, most likely due to competition for electrons with the aerobic respiratory chain. Another gene, nirC, is located upstream of the nir operon. nirC encodes a putative integral membrane-spanning protein of unknown function. A nirC mutant showed no distinct phenotype.  (+info)

Changing susceptibilities of coagulase-negative staphylococci to teicoplanin in a teaching hospital. (5/3560)

The susceptibility of two collections of coagulase-negative staphylococci (CNS) isolated from clinical specimens for teicoplanin and vancomycin were compared. They comprised 91 and 101 isolates, collected in 1985 and 1994 respectively, from different departments of a teaching hospital. MICs of vancomycin and teicoplanin were determined by a modified Etest method. Additionally, a disc diffusion test was performed for teicoplanin. All isolates were susceptible to vancomycin (MIC < or = 4 mg/L). Two of the 91 isolates collected in 1985 were intermediate to teicoplanin (MIC between 8 and 32 mg/L), whereas in 1994 the number of intermediate isolates was 20 out of 101 (P < 0.01). The correlation between MICs, as determined by the modified Etest assay, and disc diffusion zones was poor (r = -0.35). Results show that resistance to teicoplanin in CNS has increased in the study hospital over a period of 9 years. This increase is likely to be correlated with the introduction of teicoplanin. Furthermore, a disc diffusion method does not appear to be the first method of choice for detection of strains of CNS with diminished susceptibility to teicoplanin.  (+info)

Evidence for nasal carriage of methicillin-resistant staphylococci colonizing intravascular devices. (6/3560)

Nasal surveillance cultures were performed for 54 patients exhibiting >/=10(3) CFU of methicillin-resistant coagulase-negative staphylococci per ml in central venous catheter (CVC) rinse cultures over a 6-month period. Forty-two of the nasal cultures yielded growth of methicillin-resistant coagulase-negative staphylococci, and 33 of the 42 cultures contained organisms that belonged to the same species as the CVC isolates. Of the 33 same-species isolates, 20 appeared to be identical strains by pulsed-field gel electrophoresis analysis. These data suggest that measures should be taken to reduce cross-contamination between the respiratory tract and intravascular devices. However, the potential interest in detecting methicillin-resistant coagulase-negative staphylococcus carriage in high-risk patients is hampered by the lack of sensitivity of nasal surveillance cultures.  (+info)

Penicillin-binding protein-mediated resistance in pneumococci and staphylococci. (7/3560)

Target alteration underlies resistance to beta-lactam antibiotics in both Staphylococcus species and Streptococcus pneumoniae. The penicillin-binding protein (PBP) targets in penicillin-resistant strains of S. pneumoniae are modified, low-binding-affinity versions of the native PBPs. Multiple PBP targets may be modified by transformation and homologous recombination with DNA from PBP genes of viridans streptococci. The level of resistance is determined by how many and to what extent targets are modified. In contrast, methicillin resistance in staphylococci is due to expression of PBP 2a, a novel, low-affinity PBP for which there is no homologue in methicillin-susceptible strains. PBP 2a is encoded by mecA, a highly conserved gene most likely acquired by a rare transposition from Staphylococcus sciuri or a closely related ancestor. Expression of resistance can be highly variable, but this seems not to be determined by PBP modifications. Several non-PBP factors are required for high-level resistance.  (+info)

Preparation of labeled staphylococcal enterotoxin A with high specific activity. (8/3560)

Staphylococcal enterotoxin A (SEA) was labeled by the chloramine-T method with 125I to a specific activity of 68 to 300 muCi per mug of SEA and with 131I to specific activity of 8 to 218 muCi per mug of SEA. SEA was partially damaged and aggregated during the labeling and storage. The damage seemed not to be greatly dependent on the specific activity of labeled entertoxin. Crossed immunoelectrophoresis showed two antigenically active and three inactive components in the ascending part of the labeled enterotoxin peak during fractionation by gel chromatography. During storage at 4 degrees C, the antigenic activity of label decreased faster when labeling had been with 131I than when with 125I. The antigenic activity of labeled SEA was lowered remarkably in the ascending part of the protein peak. Greatest release of radioiodine during storage was in the same part of protein peak. According to these results, the most suitable label for radioimmunoassay is obtained from the descending part of protein peak.  (+info)

Aims: This study was undertaken to determine the prevalence and pathogenicity of coagulase-negative staphylococci in clinical samples and to study the antibiotic-sensitivity pattern of the coagulase-negative isolates. Methods: A prospective study was conducted over a period of two years on patients admitted in the Sher-i-Kashmir Institute of Medical Sciences. Blood, urine, pus, catheter tips, cerebrospinal fluid and peritoneal fluid samples of patients who fulfilled the criteria for being labeled as nosocomial were cultured.. Results: One hundred and six strains of coagulase negative staphylococci were isolated from the samples and among them 90 isolates were identified as Staphylococcus epidermidis (84.90%). Most of the coagulase-negative staphylococci isolates were resistant to penicillin, cephalosporins and fluoroquinolones. Methicillin resistance was found in a significant number of coagulase-negative isolates. All the isolates were found to be sensitive to vancomycin.. Conclusions: The ...

Staphylococci constitute a major part of our commensal flora but are also the most common bacteria causing prosthetic joint infections (PJIs), a dreaded complication of arthroplasty surgery. However, not all staphylococci are the same. The virulent Staphylococcus aureus has the ability to cause severe disease such as bacteremia and infective endocarditis in previously healthy people, while the coagulase-negative staphylococci Staphylococcus epidermidis and Staphylococcus capitis rarely act as pathogens unless the patient is immunocompromised or has an implanted medical device, such as a prosthetic joint. This thesis accordingly explores similarities and differences between these three staphylococci in PJIs.. S. capitis can cause early postinterventional and chronic PJIs, a finding that has not previously been described. Furthermore, its nosocomial NRCS-A outbreak sublineage, recently observed in neonatal intensive care units, is also present in adult PJIs. When comparing nasal and PJI isolates, ...
The book covers updated topics on the genus Staphylococcus, including the latest discoveries. In each chapter, the author discusses the results obtained and published during her more than 20 years as a researcher in this area. The book is divided into eight chapters, with a presentation of the genus Staphylococcus, current classification, general characteristics of these bacteria and the clinical significance of coagulase-negative staphylococci (CoNS), which are often classified as mere blood culture contaminants, but are the etiological agents most commonly associated with neonatal infections and peritonitis in patients undergoing peritoneal dialysis. Coagulase-negative staphylococci can colonize the surface of catheters and produce an extracellular polysaccharide that leads to the formation of biofilms which potentiate their pathogenicity. The book also focuses on the identification of CoNS, virulence factors responsible for the symptoms and severity of infections caused by Staphylococcus spp. ...

View more ,We describe simple direct conjugation of a single TEGylated Europium chelate to DNA that binds to intracellular rRNA and is then detected using a homogeneous luminescent in situ hybridisation (LISH) technique. As a proof-of-principle, Staphylococcus aureus (S. aureus) was selected as a model for our study to show the ability of this probe to bind to intracellular 16S ribosomal rRNA. A highly purified Europium chelate conjugated oligonucleotide probe complementary to an rRNA sequence-specific S. aureus was prepared and found to be soluble and stable in aqueous solution. The probe was able to bind specifically to S. aureus via in situ hybridisation to differentiate S. aureus from a closely related but less pathogenic Staphylococcus species (S. epidermidis). A time-gated luminescent (TGL) microscope system was used to generate the high signal-to-noise ratio (SNR) images of the S. aureus. After excitation (365 nm, Chelate λmax = 335 nm), the long-lived (Eu3+) luminescent emission from ...

To the Editor: Staphylococcus pseudintermedius is a coagulase-positive species in the S. intermedius group. Previously misidentified as S. intermedius, S. pseudintermedius is now recognized as a leading cause of opportunistic infection in dogs (1) and a cause of sporadic infections in other species, including humans (1,2). Additionally, evidence of zoonotic transmission of S. pseudintermedius from dogs to humans has been reported (3,4). Although information regarding the pathogenic process of S. pseudintermedius is limited, the bacterium is known to possess virulence factors similar to those found in S. aureus, including a leukotoxin comparable to the Panton-Valentine leukocidase associated with community-acquired S. aureus infection (1).. Of concern is the emergence and widespread international recognition of methicillin-resistant S. pseudintermedius (MRSP) (1). One veterinary laboratory noted a 272% increase in MRSP cases from 2007-2008 through 2010-2011 (5). As with methicillin-resistant S. ...
Washington MA, Kajiura L, Leong MK, Agee W, Barnhill JC 15(1). 100 - 104 (Journal Article). Staphylococcus sciuri is an emerging gram-positive bacterial pathogen that is infrequently isolated from cases of human disease. This organism is capable of rapid conversion from a state of methicillin sensitivity to a state of methicillin resistance and has been shown to express a set of highly effective virulence factors. The antibioticresistance breakpoints of S. sciuri differ significantly from the more common Staphylococcus species. Therefore, the rapid identification of S. sciuri in clinical material is a prerequisite for the proper determination of the antibiotic- resistance profile and the rapid initiation of antimicrobial therapy. Here, we present a brief literature review of S. sciuri and an entomological case study in which we describe the colonization of an American cockroach with this agent. In addition, we discuss potential implications for the distribution and evolution of antibiotic- ...
Methicillin resistance in Staphylococcus spp. results from the expression of an alternative penicillin-binding protein 2a (encoded by mecA) with a low affinity for β-lactam antibiotics. Recently, a novel variant of mecA known as mecC (formerly mecALGA251) was identified in Staphylococcus aureus isolates from both humans and animals. In this study, we identified two Staphylococcus sciuri subsp. carnaticus isolates from bovine infections that harbour three different mecA homologues: mecA, mecA1 and mecC ...

Staphylococci are a worldwide cause of human and animal infection and are considered to be of the most common causes of infections in birds. Enterotoxins produced by some staphylococcal species were recognized as a causative agent of staphylococcal food poisoning (SFP). Only enterotoxins produced by Staphylococcus aureus were as yet well characterized. Much less is known about enterotoxigenic potential of coagulase-negative species of genus Staphylococcus (CNS). It has been reported that enterotoxigenic CNS strains have been associated with human and animal infections and food poisoning. Samples collected from chicken production cycle (un hatched eggs, baby chicks, broilers, chicken meat and table eggs) in Luxor, Egypt were tested to investigate the presence of Staphylococcus species and detection of their enterotoxines genes with more special attention for detection of methicillin resistance gene (mec A).

We describe here a strategy that can distinguish between Staphylococcus species truly present in a clinical sample from contaminating Staphylococcus species introduced during the testing process. Contaminating Staphylococcus species are present at low levels in PCR reagents and colonize lab personnel. To eliminate detection of contaminants, we describe an approach that utilizes addition of sufficient quantities of either non-target Staphylococcal cells (Staphylococcus succinus or Staphylococcus muscae) or synthetic oligonucleotide templates to helicase dependent isothermal amplification reactions to consume Staphylococcus-specific tuf and mecA gene primers such that contaminating Staphylococcus amplification is suppressed to below assay limits of detection. The suppressor template DNA is designed with perfect homology to the primers used in the assay but an internal sequence that is unrelated to the Staphylococcal species targeted for detection. Input amount of the suppressor is determined by a
The clinical variables associated with isolation of oxacillin- and methicillin-resistant, coagulase-negative staphylococci (CNS) from blood cultures of hospitalized patients were studied. One hundred CNS strains (49 oxacillin-susceptible; 51 oxacillin-resistant) isolated consecutively from one of two or more sets of blood cultures were collected. Only two variables were independently associated with recovery of oxacillin/methicillin-resistant strains by a multivariate analysis: length of hospital stay | 10 days (OR 5.2, 95% CI = 1.7-15.7), and administration of antimicrobial agents in the previous 14 days (OR 4.5, 95% CI = 1.7-11.7). Analysis of the antibiotics administered indicated that only beta-lactams were associated with a statistically significant risk of resistance to oxacillin/methicillin (OR of beta-lactams vs no antibiotics = 6.94, 95% CI = 1.9-25.3; OR of non-beta-lactams vs no antibiotics = 2.64, 95% CI = 0.8-8.3).

Determining the cause of mastitis is important because not all cases of mastitis benefit from antibiotic therapy. For instance, Gram positive bacteria, such as Staph aureus and coagulase negative behave differently in the cow and have different responses to therapy. Being able to identify between the two can help us make appropriate treatment decisions for managing mastitis in our herds. One way to do that is through on farm culturing. In this episode, Dr. Pamela Ruegg teaches us how to identify Staphylococcus species on our cultured media plates whether we are using bi-, tri- or quad plates..

We have shown that there are at least three distinct types of SCCmec in the chromosome of MRSA worldwide. SCCmec was defined as the DNA element on the MRSA chromosome demarcated by a pair of direct repeats and inverted repeats, havingccr genes required for its movement and carrying themecA gene (14, 17). As far as we could judge from the structure of the two elements newly identified in this study, they seem to constitute a family of SCCmec together with N315-type SCCmec.. The mecA gene is considered to have originated in some coagulase-negative staphylococcus species (36) and was then transferred into S. aureus to generate MRSA (1,13, 32). It is likely that SCCmec serves as the carrier of the mecA gene moving across staphylococcal species, since mecA genes in other staphylococcal species have never been found without the accompaniment of SCCmec-like structure (T. Ito and Y. Katayama, unpublished observation). Since both ccrA and ccrB genes are required for the integration event, we considered ...
Results: The results showed 91 isolates (56.88%) were coagulase-positive, and 69 isolates (43.12%) were coagulase-negative Staphylococcus aureus (CNSA). Out of 91 (56.88%) coagulase-positive staphylococci, 32 isolates (35.16%) were resistant to cefoxitin, and 30 isolates (32.96%) were resistant to oxacillin, using disc diffusion method. PCR revealed the presence of the femA gene (510 bp band) in all coagulase-positive isolates (100%), and the mecA gene (513 bp band) was detected in 32 isolates (35.16%); out of 32 MRSA isolates, 13 isolates (40.62%) were positive for presence of the luk-pv gene (433 bp band). ...
Staphylococci are the most abundant skin-colonizing bacteria and the most important causes of nosocomial infections and community-associated skin infections. and birds [1]. Two main groups are distinguished by their ability to coagulate blood: coagulase-positive staphylococci, with the most important species being or as a subject, owing to its eminent role in human contamination. The nose is the most important site PNU 282987 of colonization [3], but is situated in the pharynx also, perineum, axillae and on your skin (predominantly over the hands, upper body and abdomen) [4C6]. Consistent colonization with is normally observed in around 20% of the populace, while 30% bring transiently, and around 50% are non-carriers [7,8]. In consistent providers, who all possess within their noses, the regularity of colonization of various other body sites is normally increased weighed against the general people [9]. Consistent carriage prices are higher in kids than adults [4]. Oddly enough, theres been a ...

MRSA is a yellow staphylococcus bacterium. The difference between other yellow staphylococci and MRSA is that MRSA is resistant to certain antibiotics. This means that if you get an infection, there are fewer antibiotics that can be used. Another word for resilience is resistance.. It is common to have bacteria like yellow staphylococci on the body without having any problems. Its called being a carrier. The staphylococci are usually present in the nose, throat or other mucous membranes. You can also wear them on the skin, for example in groin and armpits.. ...

PURPOSE: To evaluate the fluoroquinolone susceptibilities of ocular isolate coagulase-negative staphylococci (CoNS), identified at the Microbiology Laboratory - UNIFESP. DESIGN: Experimental laboratory investigation. METHODS: The minimum inhibitory concentrations (MICs) of 21 strains of methicillin-resistant coagulase-negative staphylococci (MRCoNS) and 22 methicillin-sensitive coagulase-negative staphylococci (MSCoNS) to ciprofloxacin, ofloxacin, gatifloxacin and moxifloxacin were determined, using the E-test method standardized by the Clinical and Laboratory Standards Institute (CLSI/NCCLS). RESULTS: The MIC90s (µg/ml) for the second generation of tested fluoroquinolones were higher than the fourth generation, especially for the methicillin-resistant coagulase-negative staphylococci group. CONCLUSION: Our results indicate that methicillin-sensitive coagulase-negative staphylococci are more susceptible to quinolones than are methicillin-resistant coagulase-negative staphylococci and that ...
Deoxyribonucleic acid relatedness studies (S1 nuclease method) showed that 23 unidentified Staphylococcus strains form two homogeneous genomic species related 1 to 9% to 24 type strains representing known Staphylococcus species. These new species were named Staphylococcus lugdunensis and Staphylococcus schleiferi. Strains of S. lugdunensis were susceptible to novobiocin, produced a fibrinogen affinity factor, and failed to produce coagulase, heat-stable nuclease, and staphylokinase. S. lugdunensis strains differed from S. hominis (the phenotypically closest species) by production of ornithine decarboxylase and the fibrinogen affinity factor. The guanine-plus-cytosine content of the deoxyribonucleic acid was 32 mol%. The type strain is N860297 (= ATCC 43809). Strains of S. schleiferi were susceptible to novobiocin, produced a heat-stable nuclease and a fibrinogen affinity factor, and failed to produce coagulase and staphylokinase. S. schleiferi strains differed from S. aureus by production of an

To investigate whether there is a similar relationship between mecA and gyrA in coagulase-negative staphylococci (CNS), mecA- and gyrA-specific DNA fragments were used to probe methicillin-resistant isolates of Staphylococcus epidermidis (MRSE) (n = 11) and Staphylococcus haemolyticus (MRSH) (n = 11). The gyrA probe hybridized to the same SmaI DNA fragment as the mecA probe in all strains tested. However, since the size of the SmaI fragments containing meca and gyrA varied from 73 to 600 kb, the distance between the two genes was determined more precisely. Cloned mecA or gyrA fragments plus vector sequences each ...
TY - JOUR. T1 - From clinical microbiology to infection pathogenesis. T2 - How daring to be different works for Staphylococcus lugdunensis. AU - Frank, Kristi L.. AU - Del Pozo, José Luis. AU - Patel, Robin. PY - 2008/1. Y1 - 2008/1. N2 - Staphylococcus lugdunensis has gained recognition as an atypically virulent pathogen with a unique microbiological and clinical profile. S. lugdunensis is coagulase negative due to the lack of production of secreted coagulase, but a membrane-bound form of the enzyme present in some isolates can result in misidentification of the organism as Staphylococcus aureus in the clinical microbiology laboratory. S. lugdunensis is a skin commensal and an infrequent pathogen compared to S. aureus and S. epidermidis, but clinically, infections caused by this organism resemble those caused by S. aureus rather than those caused by other coagulase-negative staphylococci. S. lugdunensis can cause acute and highly destructive cases of native valve endocarditis that often ...
S. lugdunensis is a recently described coagulase negative Staphylococcus species that has been determined by our group and others to be a virulent human pathogen, capable of causing diseases more akin to Staphylococcus aureus than a typical coagulase negative Staphylococcus species (e.g., native valve endocarditis). This suggests that this species has unique characteristics differentiating it from other coagulase negative Staphylococcus species. The types of infection caused by S. lugdunensis, supported by data generated in our laboratory demonstrating the ability of this organism to form biofilm, suggest that biofilm formation contributes to this species virulence.. We have identified a locus with homology to the S. aureus and Staphylococcus epidermidis ica loci in S. lugdunensis. Interestingly, S. lugdunensis forms biofilm, but its biofilm extracellular matrix is predominantly proteinaceous. Understanding the mechanisms of biofilm formation in S. lugdunensis should enable new, more effective ...
This study was conducted to determine the frequency of Staphylococcus lugdunensis in different clinical samples. Out of 690 clinical samples, a total of 178 coagulase negative staphylococci (CoNS) isolates were recovered. CoNS were identified as 10 different species; 22 isolates belonged to Staphylococcus lugdunensis. Two specific genes for S. lugdunensis were used (tanA gene and fbl gene) to confirm identification. Both of these specific genes were detected in 15 (68.1%) of 22 isolates that were identified phenotypically. The results of oxacillin MIC showed that 7 of the 15 (46.6%) S. lugdunensis isolates were oxacillin resistant. The antibiotic susceptibility testing against 16 antibiotics showed that resistance rates were variable towards these antibiotics. Eight of fifteen S. lugdunensis isolates (53.3%) were β-lactamase producer. Results of molecular detection of mecA gene found that mecA gene was detected in 6 (40%) of 15 S. lugdunensis. All of these 6 isolates (S1, S2, S3, S4, S5, and ...

Staphylococcus saprophyticus is an important cause of urinary tract infection (UTI), particularly among young women, and is second only to uropathogenic Escherichia coli as the most frequent cause of UTI. The molecular mechanisms of urinary tract colonization by S. saprophyticus remain poorly understood. We have identified a novel 6.84 kb plasmid-located adhesin-encoding gene in S. saprophyticus strain MS1146 which we have termed uro-adherence factor B (uafB). UafB is a glycosylated serine-rich repeat protein that is expressed on the surface of S. saprophyticus MS1146. UafB also functions as a major cell surface hydrophobicity factor. To characterize the role of UafB we generated an isogenic uafB mutant in S. saprophyticus MS1146 by interruption with a group II intron. The uafB mutant had a significantly reduced ability to bind to fibronectin and fibrinogen. Furthermore, we show that a recombinant protein containing the putative binding domain of UafB binds specifically to fibronectin and ...
Aim: This Swedish study determined which species of coagulase-negative staphylococci (CoNS) were found in neonatal blood cultures and whether they included Staphylococcus capitis clones with decreased susceptibility to vancomycin. Methods: CoNS isolates (n = 332) from neonatal blood cultures collected at orebro University Hospital during 1987-2014 were identified to species level with matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS). The antibiotic susceptibility pattern of S. capitis isolates was determined by the disc diffusion test and Etest, and the presence of heterogeneous glycopeptide-intermediate S. capitis (hGISC) was evaluated. Results: Staphylococcus epidermidis (67.4%), Staphylococcus haemolyticus (10.5%) and S. capitis (9.6%) were the most common CoNS species. Of the S. capitis isolates, 75% were methicillin-resistant and 44% were multidrug-resistant. No isolate showed decreased susceptibility to vancomycin, but at least 59% displayed the ...
Antimicrobial resistance patterns and gene coding for methicillin resistance (mecA) were determined in 25 S. aureus and 75 Coagulase Negative Staphylococci (CNS) strains isolates from half-udder milk samples collected from goats with subclinical mastitis. Fourteen (56.0%) S. aureus and thirty-one (41.3%) CNS isolates were resistant to one or more antimicrobial agents. S. aureus showed the highest resistance rate against kanamycin (28.0%), oxytetracycline (16.0%), and ampicillin (12.0%). The CNS tested were more frequently resistant to ampicillin (36.0%) and kanamycin (6.7%). Multiple antimicrobial resistance was observed in eight isolates, and one Staphylococcus epidermidis was found to be resistant to six antibiotics. The mecA gene was not found in any of the tested isolates. Single resistance against β-lactamics or aminoglicosides is the most common trait observed while multiresistance is less frequent. ...
Coagulase negative staphylococci (CoNS) are important reservoirs of antibiotic resistance genes and associated mobile genetic elements and are believed to contribute to the emergence of successful methicillin resistant Staphylococcus aureus (MRSA) clones. Although, these bacteria have been linked to various ecological niches, little is known about the dissemination and genetic diversity of antibiotic resistant CoNS in general public settings. Four hundred seventy-nine samples were collected from different non-healthcare/general public settings in various locations (n = 355) and from the hands of volunteers (n = 124) in London UK between April 2013 and Nov 2014. Six hundred forty-three staphylococcal isolates belonging to 19 staphylococcal species were identified. Five hundred seventy-two (94%) isolates were resistant to at least one antibiotic, and only 34 isolates were fully susceptible. Sixty-eight (11%) mecA positive staphylococcal isolates were determined in this study. SCCmec types were fully

A new cyclic depsipeptide (1) has been isolated from culture broth of Staphylococcus sp. (No. P-100826-4-6) derived from Corallina officinalis L., together with the known compounds indol-3-carboxylic acid (2), 1,5-dideoxy-3-C-methyl arabinitol (3), thymine (4), uracil (5), cyclo (L-pro-L-omet) (6) and macrolactin B (7). The structure of (1) was established to be cyclo (2α, 3-diaminopropoinc acid-L-Asn-3-β-hydroxy-5-methyl-tetradecanoic acid-L-Leu1-L-Asp-L-Val-L-Leu2-L-Leu3) by extensive spectroscopic techniques including 1H NMR, 13C NMR, 1H‒1H COSY, HMBC, HSQC, NOESY, and HRFABMS. The antimicrobial activities of compounds 1–7 were evaluated. Compounds 1–5, and 7 showed moderate antimicrobial activity while compound 6 exhibited a potent antimicrobial and antifungal activities.
BACKGROUND: Antimicrobial resistance may compromise the efficacy of antibiotic prophylaxis before surgery. The aim of this study was to measure susceptibility and clonal distribution of coagulase-negative staphylococci (CoNS) colonizing the skin around the surgery access site before and after the procedure. METHODS: From March to September 2004, a series of 140 patients undergoing elective major abdominal surgery were screened for CoNS colonization at admission and 5 days after surgery. All isolates were tested for antibiotic susceptibility and genotyped by pulsed-field gel electrophoresis (PFGE). RESULTS: Colonization rates with CoNS at admission and after surgery were 85% and 55%, respectively. The methicillin-resistant CoNS rate increased from 20% at admission to 47% after surgery (P = 0.001). The PFGE pattern after surgery revealed more patients colonized with identical clones: 8/140 patients (8/119 strains) and 26/140 patients (26/77 strains), respectively (P , 0.001). CONCLUSIONS: Our ...
Abstract : Staphylococcus saprophyticus (S. saprophyticus) is a frequent cause of urinary tract infection in the young women.The current study was designed to analyze the effect of biofield energy treatment on S. saprophyticus for evaluationof its antibiogram profile, biochemical reactions pattern and biotyping characteristics. Two sets of ATCC sampleswere taken in this experiment and denoted as A and B. Sample A was revived and divided into two parts Group (Gr.I)(control) and Gr.II (revived); likewise, sample B was labeled as Gr.III (lyophilized). Gr. II and III were given with Mr.Trivedis biofield energy treatment. The control and treated groups of S. saprophyticus cells were tested with respect toantimicrobial susceptibility, biochemical reactions pattern and biotype number using MicroScan Walk-Away® system.The 50% out of twenty-eight tested antimicrobials showed significant alteration in susceptibility and 36.67% out of thirtyantimicrobials showed an alteration in minimum inhibitory ...
The objectives of this study were to determine the occurrence and diversity of Staphylococcus spp. in milk from healthy cows and cows with subclinical mastitis in Brazil and to examine the profile of enterotoxin genes and some enterotoxins produced by Staphylococcus spp. A total of 280 individual mammary quarter milk samples from 70 healthy cows and 292 samples from 73 cows with subclinical mastitis were collected from 11 farms in the state of Sao Paulo, Brazil. Staphylococcus spp. were recovered from 63 (22.5%) samples from healthy cows and from 80 samples (27.4%) from cows with mastitis. The presence of Staphylococcus aureus was significantly different between these 2 groups and was more prevalent in the cows with mastitis. The presence of Staphylococcus saprophyticus was also significantly different between these 2 groups, but this organism was more prevalent in healthy cows. No statistically significant differences were observed in the numbers of other staphylococci in milk samples from the ...
A putative staphylococcal protein A (spa) gene was discovered in the genome of Staphylococcus pseudintermedius and used for developing a species-specific spa typing protocol. Thirty-one clinical methicillin-resistant S. pseudintermedius (MRSP) isolates from dogs and cats in four countries were characterized by spa typing, pulsed-field gel electrophoresis (PFGE) and staphylococcal cassette chromosome (SCCmec) typing. The results indicated the occurrence of two MRSP clones that acquired distinct SCCmec elements in Europe (t02, PFGE type A, SCCmec type III,) and California (t06, PFGE type B, SCCmec type V). Sequence analysis of mecA revealed the occurrence of four alleles (mecA1 to mecA4), which correlated with the geographical origin of the isolates and enabled discrimination of two distinct subtypes within the European clone. The newly developed spa typing method appeared to be a promising tool for easy and rapid typing of MRSP, either alone or in combination with SCCmec and mecA typing for ...
Staphylococcus lugdunensis is a species of coagulase-negative staphylococcus (CoNS) that causes serious infections in humans akin to those of S. aureus. It was often misidentified as S. aureus, but this has been rectified by recent routine use of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) in diagnostic laboratories. It encodes a diverse array of virulence factors for adhesion, cytotoxicity, and innate immune evasion, but these are less diverse than those encoded by S. aureus. It expresses an iron-regulated surface determinant (Isd) system combined with a novel energy-coupling factor (ECF) mechanism for extracting heme from hemoproteins. Small cytolytic S. lugdunensis synergistic hemolysins (SLUSH), peptides related to phenol-soluble modulins of S. aureus, act synergistically with β-toxin to lyse erythrocytes. S. lugdunensis expresses a novel peptide antibiotic, lugdunin, that can influence the nasal and skin microbiota. Endovascular infections ...
An agr homologue of Staphylococcus saprophyticus was identified, cloned and sequenced. The gene locus shows homologies to other staphylococcal agr systems, especially to those of S. epidermidis and S. lugdunensis. A putative RNAIII was identified and found to be differentially expressed during the growth phases. In contrast to the RNAIII molecules of S. epidermidis and S. aureus it does not contain an open reading frame that codes for a protein with homologies to the d-toxin. Using PCR, the agr was found to be present in clinical isolates of S. saprophyticus. ...
Staphylococcus pseudintermedius (SP) is part of the normal microbiota of dogs and cats. Since the mid-1980s, an ever-increasing number of methicillin-resistant SP (MRSP) isolates have been reported. In the mid-2000s, two predominant MRSP clones, ST71 (sequence type 71) and ST68, spread through Europe and North America, respectively. MRSP isolates are commonly multidrug resistant (MDR), and are thus capable of causing infections that do not respond to routinely used antimicrobials. MRSP appeared in the small animal population of Finland in the late 2000s, also causing numerous infections at the Veterinary Teaching Hospital (VTH) of the University of Helsinki. No data on the epidemiology of MRSP in Finland have been published. This thesis study aimed to explore the epidemiology of MRSP in the Finnish small animal population. This was done by investigating and describing the MRSP outbreak at the VTH, and investigating risk factors for patients being colonized or infected by MRSP in the hospital ...

Meticillin-resistant Staphylococcus pseudintermedius (MRSP) has recently emerged as a worldwide cause of canine pyoderma. In this study, we characterized 22 S. pseudintermedius isolates cultured from 19 dogs with pyoderma that attended a veterinary dermatology referral clinic in Australia in 2011 and 2012. Twelve isolates were identified as MRSP by mecA real-time PCR and phenotypic resistance to oxacillin. In addition to β-lactam resistance, MRSP isolates were resistant to erythromycin (91.6 %), gentamicin (83.3 %), ciprofloxacin (83.3 %), chloramphenicol (75 %), clindamycin (66 %), oxytetracycline (66 %) and tetracycline (50 %), as shown by disc-diffusion susceptibility testing. Meticillin-susceptible S. pseudintermedius isolates only showed resistance to penicillin/ampicillin (90 %) and tetracycline (10 %). PFGE using the SmaI restriction enzyme was unable to type nine of the 12 MRSP isolates. However the nine isolates provided the same PFGE pulsotype using the Cfr91 restriction enzyme. ...
The objective of the present study was to determine the antimicrobial resistance profile of planktonic and biofilm cells of Staphylococcus aureus and coagulase-negative staphylococci (CoNS). Two hundred Staphylococcus spp. strains were studied, including 50 S. aureus and 150 CoNS strains (50 S. epidermidis, 20 S. haemolyticus, 20 S. warneri, 20 S. hominis, 20 S. lugdunensis, and 20 S. saprophyticus). Biofilm formation was investigated by adherence to polystyrene plates. Positive strains were submitted to the broth microdilution method to determine the minimum inhibitory concentration (MIC) for planktonic and biofilm cells and the minimal bactericidal concentration for biofilm cells (MBCB). Forty-nine Staphylococcus spp. strains (14 S. aureus, 13 S. epidermidis, 13 S. saprophyticus, 3 S. haemolyticus, 1 S. hominis, 3 S. warneri, and 2 S. lugdunensis) were biofilm producers. These isolates were evaluated regarding their resistance profile. Determination of planktonic cell MIC identified three (21.4%) S.

Coagulase-negative staphylococci (CoNS) are a major cause of nosocomial blood stream infection, especially in critically ill and haematology patients. CoNS are usually multidrug-resistant and glycopeptide antibiotics have been to date considered the drugs of choice for treatment. The aim of this study was to characterize CoNS with reduced susceptibility to glycopeptides causing blood stream infection (BSI) in critically ill and haematology patients at the University Hospital Tor Vergata, Rome, Italy, in 2007. Hospital microbiology records for transplant haematology and ICU were reviewed to identify CoNS with elevated MICs for glycopeptides, and isolates were matched to clinical records to determine whether the isolates caused a BSI. The isolates were tested for susceptibility to new drugs daptomicin and tigecycline and the genetic relationship was assessed using f-AFLP. Of a total of 17,418 blood cultures, 1,609 were positive for CoNS and of these, 87 (5.4%) displayed reduced susceptibility to
Our results suggest that the majority of SIG strains isolated from commensal flora or infection sites in dogs are reclassified as being S. pseudintermedius strains. In fact, S. intermedius CCUG 50815 and S. intermedius CCUG 51770 (both of dog origin) obtained from the Culture Collections of the University Göteborg (CCUG) were also identified as being S. pseudintermedius strains by molecular phylogenetic analyses. Previously, we also reported that S. pseudintermedius was a common species among methicillin-resistant coagulase-positive staphylococci in dogs (28).. Van Hoovels et al. reported the first case of S. pseudintermedius infection in a human (33). In the present study, we also identified two strains from humans as being S. pseudintermedius strains, one of which (strain TW 6698) had been identified as being S. intermedius before our reclassification (18). Although there have been reports that S. intermedius strains were isolated from human infection or food poisoning from dog origins (15, ...

One of the most important phenotypical features used in the classification of staphylococci is their ability to produce coagulase, an enzyme that causes blood clot formation. Seven species are currently recognised as being coagulase-positive: S. aureus, S. delphini, S. hyicus, S. intermedius, S. lutrae, S. pseudintermedius, and S. schleiferi subsp. coagulans. These species belong to two separate groups - the S. aureus (S. aureus alone) group and the S. hyicus-intermedius group (the remaining five). An eighth species has also been described - Staphylococcus leei - from patients with gastritis.[17]. S. aureus is coagulase-positive, meaning it produces coagulase. However, while the majority of S. aureus strains are coagulase-positive, some may be atypical in that they do not produce coagulase. S. aureus is catalase-positive (meaning that it can produce the enzyme catalase) and able to convert hydrogen peroxide (H2O2) to water and oxygen, which makes the catalase test useful to distinguish ...
Staphylococcus aureus and coagulase negative staphylococci (CNS) were isolated from ovine and caprine mastitis milk samples originating from more than 40 Swiss farms. CNS dominated as causal microorganisms of mastitis in small ruminants. By restriction fragment length polymorphism (RFLP) analysis of the groEL gene and sequencing of 16S rDNA, various CNS species were identified, albeit certain of them predominated. For susceptibility testing of mastitis pathogens to selected antibiotics, minimal inhibitory concentrations were determined. Of the 67 S. aureus and 208 CNS strains, 31.3 % and 8.2 % were resistant to penicillin, 29.9 % and 1.0 % to ampicillin, 1.5 % and 10.6 % to erythromycin, and 3.0 % and 7.7 % to tetracycline, respectively. Moreover, 10 CNS strains (4.8 %) were resistant to oxacillin and one CNS strain to sulfamethoxazole/trimethoprim. The results obtained describe for the first time the resistance situation of mastitis pathogens from sheep and goats in Switzerland. However, ...
The cell surface-associated extracellular adherence protein (Eap) mediates adherence of Staphylococcus aureus to host extracellular matrix components and inhibits inflammation, wound healing, and angiogenesis. A well-characterized collection of S. aureus and non-S. aureus staphylococcal isolates (n = 813) was tested for the presence of the Eap-encoding gene (eap) by PCR to investigate the use of the eap gene as a specific diagnostic tool for identification of S. aureus. Whereas all 597 S. aureus isolates were eap positive, this gene was not detectable in 216 non-S. aureus staphylococcal isolates comprising 47 different species and subspecies of coagulase-negative staphylococci and non-S. aureus coagulase-positive or coagulase-variable staphylococci. Furthermore, non-S. aureus isolates did not express Eap homologs, as verified on the transcriptional and protein levels. Based on these data, the sensitivity and specificity of the newly developed PCR targeting the eap gene were both 100%. Thus, the ...

Background: The aim of this study was to investigate the antimicrobial effects of ethanol extractof Eremurus persicus leaves on Staphylococcus aureus under laboratory condition. Methods: The ethanol extract of paste leaves were collected using a rotary machine. 12 strain of Staphylococcus aureus were collected from urinary tract infection of Zabol city (Iran). Results: The results showed that MIC and also MBC of Eremurus persicus ethanol extract against Staphylococcus aureus were 5 and 2.55 ppm, respectively. Conclusion: The results of this study showed that ethanol extract of Eremurus persicus leaves has a significant antibacterial effect and can be used to deal with specific pathogenic bacteria.

Results: The incidence of NIs was low (i.e. , 2%). Among 16936 admitted patients in this hospital, 174 patients (79 males and 95 females) with a mean age of 51.7 ± 24.6 years (range, 5 to 90 years) were diagnosed with an NI. Incidence density of NIs were 3.18% in infectious diseases ward, 2.17% in intensive care unit (ICU), 2% in orthopedic ward, 0.68% in obstetrics and gynecology (OBGYN) ward and 0.278% in general surgery. Regarding the etiology of infection, coagulase-negative staphylococci in 23.69%, Bacillus in 21.05%, Escherichia coli was found in 18.42%, and coagulase-positive staphylococci in 13.16% of the cases. The results indicated that coagulase-negative staphylococci was the most frequent pathogen. ...
