Staphylococcus cohnii is a Gram-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. The species commonly lives on human skin; clinical isolates have shown high levels of antibiotic resistance. A strain of S. cohnii was found to contain a mobile genetic element very similar to the staphylococcal cassette chromosome encoding methicillin resistance element seen in Staphylococcus aureus.

Staphylococcus sciuri is a Gram-positive, oxidase-positive, coagulase-negative member of the bacterial genus Staphylococcus consisting of clustered cocci. The type subspecies S. sciuri subsp. sciuri was originally used to categorize 35 strains shown to use cellobiose, galactose, sucrose, and glycerol. Kloos, W. E.; Schliefer, K. H.; Smith R. F.

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. ...
Staphylococcus warneri lipase 2: A gene encoding an extracellular lipase was identified in Staphylococcus warneri 863; amino acid sequence in first source
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. ...

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). Samples were tested for S. aureus and CNS on the basis of cultural and biochemical ...

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

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.

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..

Free-living bacteria, particularly those living in the soil or in hostile environments, represent another rich but poorly explored source of antimicrobial compounds. Many of them are difficult to cultivate in the laboratory, but recently developed techniques such as DNA transfer and metagenomics are allowing the sequencing of their entire genome and the identification of candidate molecules with antibacterial activity.. Our body also harbors a large quantity of bacteria, virus and fungi. In our gut alone we have trillions of bacteria (more than 1,000 different species and 3 million genes). This microbiota is not only harmless, but it can also defend us against pathogenic bacteria. Thus, a Staphylococcus that normally inhabits our nose secretes a peptide (called lugdunin) that inhibits colonization by the pathogenic Staphylococcus aureus.. Nature offers numerous options to fight antibiotic-resistant bacteria, such as natural products derived from the sea, bacteria living in hostile environments, ...
HPrKC is very similar to the corresponding domain from the L. casei enzyme (27). The two molecules have an amino acid sequence identity of 48% and superimpose with an rmsd value of 1.3 Å, aligning 148 Cα atoms out of 155 corresponding residues. It is made up of a central five-stranded mixed β-sheet flanked by four α-helices and by two smaller β-sheets (Fig. 6, which is published as supporting information on the PNAS web site). According to DALI (31), the structure resembles AdK (27, 32) and has an even higher similarity with the C-terminal domain of PCK (Fig. 6; ref. 33), which DALI returns with a score of 7.8, aligning 128 structurally equivalent Cα atoms with an rmsd value of 2.8 Å. A multiple sequence alignment (not shown), including members of HPrK and PCK families, indicates significant sequence similarity, suggesting that the two proteins are, in fact, evolutionarily related.. It was not unexpected from the crystallization conditions to find a phosphate ion Pi in the P-loop (ref. ...

abstract = {Drosophila melanogaster is a useful model to investigate mucosal immunity. The immune response to intestinal infections is mediated partly by the Immune deficiency (IMD) pathway, which only gets activated by a type of peptidoglycan lacking in several medically important Gram-positive bacterial species such as Staphylococcus. Thus, the intestinal host defense against such bacterial strains remains poorly known. Here, we have used Staphylococcus xylosus to develop a model of intestinal infections by Gram-positive bacteria. S. xylosus behaves as an opportunistic pathogen in a septic injury model, being able to kill only flies immunodeficient either for the Toll pathway or the cellular response. When ingested, it is controlled by IMD-independent host intestinal defenses, yet flies eventually die. Having excluded an overreaction of the immune response and the action of toxins, we find that flies actually succumb to starvation, likely as a result of a competition for sucrose between the ...
The imidazole glycerophosphate dehydratase (IGPD) protein is a therapeutic target for herbicide discovery. It is also regarded as a possible target in Staphylococcus xylosus (S. xylosus) for solving mastitis in the dairy cow. The 3D structure of IGPD protein is essential for discovering novel inhibitors during high-throughput virtual screening. However, to date, the 3D structure of IGPD protein of S. xylosus has not been solved. In this study, a series of computational techniques including homology modeling, Ramachandran Plots, and Verify 3D were performed in order to construct an appropriate 3D model of IGPD protein of S ...

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

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. ...
A new cyclic depsipeptide (1) has been isolated from culture broth of Staphylococcus sp.

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 ...
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 ...
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, ...

From a total of 40 characters that were previously used to differentiate species of staphylococci, 13 key characters were selected to make a simplified scheme that could be easily used by the routine clinical laboratory for identifying human staphylococci. These key characters included coagulase activity, hemolysis, nitrate reduction, and aerobic acid production from fructose, xylose, arabinose, ribose, maltose, lactose, sucrose, trehalose, mannitol, and xylitol. In the simplified scheme, 924 strains of staphylococci were placed into 11 positions, each of which contained the major portion (greater than or equal to 80%) of strains of one of the recognized species. Several positions contained a rare or few uncommon strains of one or more additional species and these could be resolved on the basis of other key characters. ...

Coagulase is a protein enzyme produced by several microorganisms that enables the conversion of fibrinogen to fibrin. In the laboratory, it is used to distinguish between different types of Staphylococcus isolates. Importantly, S. aureus is coagulase-positive, meaning that coagulase negativity excludes S. aureus.. It is also produced by Yersinia pestis.. Coagulase reacts with prothrombin in the blood. The resulting complex is called staphylothrombin, which enables the enzyme protease to convert fibrinogen to fibrin. This results in clotting of the blood. Coagulase is tightly bound to the surface of the bacterium S. aureus and can coat its surface with fibrin upon contact with blood. It has been proposed that fibrin-coated staphylococci resist phagocytosis, making the bacteria more virulent. Bound coagulase is part of the larger family of MSCRAMM. ...

This is an increasingly common question, as methicillin-resistant Staphylococcus pseudintermedius (MRSP - essentially the canine version of the high-profile human "superbug" MRSA) has expanded greatly in the canine population. As more dogs get MRSP infections and even more become inapparent carriers of this bug, more dogs that are carriers will need surgery (both elective and non-elective). Since MRSP is now a leading cause of surgical site infections in dogs, theres concern about what to do with these carriers, particularly when it comes to elective surgeries like spays and neuters.. My answer to the question is… maybe.. If the dog has an active MRSP infection (e.g. skin infection), Id say "hold off for a while" if possible. I dont like elective surgeries being done on animals with active infections (this applies to almost any kind of infection, not just MRSP). If an animal has an active MRSP infection, it might increase the risk of the surgical site becoming infected because of the ...

The phosphoenolpyruvate (PEP)-dependent phosphotransferase system (PTS) is a major mechanism used by bacteria for uptake of carbohydrates, particularly hexoses, hexitols, and disaccharides, where the source of energy is from PEP. The PTS consists of two general components, enzyme I (EI) and histidine phosphocarrier protein (HPr), and of membrane-bound sugar specific permeases (enzymes II). Each enzyme II (EII) complex consists of one or two hydrophobic integral membrane domains (domains C and D) and two hydrophilic domains (domains A and B). EII complexes may exist as distinct proteins or as a single multidomain protein. The PTS catalyzes the uptake of carbohydrates and their conversion into their respective phosphoesters during transport. There are four successive phosphoryl transfers in the PTS. Initial autophosphorylation of EI, using PEP as a substrate, is followed by transfer of the phosphoryl group from EI to HPr. EIIA catalyzes the self-phosphoryl transfer from HPr after which the ...
This advanced course examines the molecular basis of interactions of microbial pathogens with their environment and various hosts, especially those which infect humans. Bacterial pathogens of global and medical significance that will be highlighted in detail include: Streptococcus pneumonia, Salmonella sp., Shigella sp., Staphylococcus sp., Mycobacterium; and Neisseria sp.

This thesis presents four studies, all designed to improve the problematic diagnostic situation concerning infants with suspected sepsis. Study I included 401 neonates with suspected sepsis. Nine signs of sepsis and C-reactive protein were prospectively recorded and logistic regression was used to assess associations between these signs and a subsequently confirmed diagnosis of sepsis. C-reactive protein and five of the clinical signs were statistically significantly associated with a positive bloodculture. When the material was stratified by gestational age, differences between premature and full term infants were detected.Studies II and III were prospective studies that used samples collected from neonates with suspected sepsis to evaluate a novel real-timepolymerase chain reaction (PCR) method. The results where compared with simultaneously collected blood cultures. Study II used plasma samples and resulted in a sensitivity of 42% and specificity of 95%. In study III, the protocol was ...

The results indicate that all Staphylococcus species used in this study had a single catalase in both exponential and stationary growth phases. Less variation in electrophoretic mobility of the Staphylococcus species suggests that this method is not useful for identification of species. Catalase activities of the seven strains were measured in both exponential and stationary growth phases. It is noteworthy that the catalase activity in exponential growth phase was higher than that in stationary growth phase for the five strains. The others maintained the catalase activity at almost the same level during the entire growth phases.. AB - We determined the divergence of some staphylococcal catalases on polyacrylamide ...
