Evaluation of MRSA-Screen, a simple anti-PBP 2a slide latex agglutination kit, for rapid detection of methicillin resistance in Staphylococcus aureus. (1/449)

The MRSA-Screen test (Denka Seiken Co., Ltd., Tokyo, Japan), consisting of a slide latex agglutination kit that detects PBP 2a with a monoclonal antibody, was blindly compared to the oxacillin disk diffusion test, the oxacillin-salt agar screen, and PCR of the mecA gene for the detection of methicillin resistance in Staphylococcus aureus. A total of 120 methicillin-susceptible S. aureus (MSSA) and 80 methicillin-resistant S. aureus (MRSA) isolates, defined by the absence or presence of the mecA gene, respectively, were tested. The MRSA-Screen test, the oxacillin disk diffusion test, and the oxacillin-salt agar screening test showed sensitivities of 100, 61.3, and 82.5% and specificities of 99.2, 96.7, and 98.3%, respectively.

Disk with high oxacillin content discriminates between methicillin-resistant and borderline methicillin-susceptible Staphylococcus aureus strains in disk diffusion assays using a low salt concentration. (4/449)

A separation between mecA+ strains of Staphylococcus aureus and strains lacking mecA was achieved by the disk diffusion assay and the agar dilution method, utilizing disks containing 5 microg of oxacillin and inocula of approximately 5 x 10(5) CFU/spot, respectively, provided that agar with 0 to 0.5% NaCl and incubation at 30 degrees C were employed. The 5-microg oxacillin disks clearly discriminated between borderline methicillin-susceptible and mecA+ strains. The oxacillin MICs were more affected by the inoculum density and salt concentration than were the methicillin MICs, and oxacillin MICs of 4 to 16 microg/ml were obtained for strains lacking mecA. Significantly higher levels of beta-lactamase production and reduced oxacillin susceptibilities were recorded for strains lacking mecA, in particular strains of phage group V, when agar with >/=2% NaCl was used than when agar with 0 to 0.5% NaCl was employed. The results indicate that the borderline methicillin-susceptible phenotype is a salt-dependent in vitro phenomenon of questionable clinical relevance.  (+info)

Evaluation of a new 3-h hybridization method for detecting the mecA gene in Staphylococcus aureus and comparison with existing genotypic and phenotypic susceptibility testing methods. (5/449)

A new 3-h hybridization assay for detection of the staphylococcal mecA gene and the Staphylococcus aureus nuclease gene was evaluated by comparing the assay with existing genotypic and phenotypic methods. A total of 275 S. aureus strains were tested, including 257 epidemiologically unrelated strains (135 mecA-positive and 122 mecA-negative; collection I), and 18 strains with known borderline resistance to methicillin (collection II). Complete agreement was obtained for both collections when comparing the new assay with genotypic methods. We further evaluated a range of phenotypic susceptibility methods recommended in Europe and/or USA using the presence of the mecA gene as the defining standard. For collection I a high degree of agreement was found for both Etests (256 strains) and the oxacillin screen plate test (255 strains); the degree of agreement was lower for agar dilution methicillin (250 strains) and oxacillin 1 microg discs (239 strains). For the borderline strains a high degree of agreement was only obtained by the oxacillin screen plate test (17 of 18 strains). The other tests were less accurate, in the following order: agar dilution methicillin, Etest methicillin, Etest oxacillin and oxacillin discs with disagreement for four, five, nine and 13 strains, respectively. In conclusion, the new hybridization assay is a rapid and exact method for detecting the mecA gene and the S. aureus nuclease gene. This study confirms that phenotypic tests for methicillin resistance in S. aureus strains creates both false-susceptible and false-resistant results, especially for borderline resistant strains.  (+info)

Topoisomerase sequences of coagulase-negative staphylococcal isolates resistant to ciprofloxacin or trovafloxacin. (6/449)

Coagulase-negative staphylococcal isolates (n = 188) were screened for susceptibility to oxacillin, ciprofloxacin, and trovafloxacin, a new fluoroquinolone. At an oxacillin concentration of >/=4 microg/ml, 43% were methicillin resistant; of these, 70% were ciprofloxacin resistant (MIC, >/=4 microg/ml). Of the methicillin-resistant, ciprofloxacin-resistant isolates, 46% were susceptible to /=8 microg/ml) and increased trovafloxacin MICs (0.25 to 2 microg/ml) could be conferred by the combined presence of single mutations in each gyrA and grlA gene. Trovafloxacin MICs of >/=8 microg/ml also occurred, but these required an additional mutation in grlA.  (+info)

The combination of a beta-lactam plus an aminoglycoside can act synergistically against S. aureus in vitro and in vivo. MiKasome, a new liposome-encapsulated formulation of conventional amikacin, significantly prolongs serum half-life (t1/2) and increases the area under the concentration-time curve (AUC) compared to free amikacin. Microbiologic efficacy and left ventricular function, as assessed by echocardiography, were compared in animals administered either oxacillin alone or oxacillin in combination with conventional amikacin or MiKasome in a rabbit model of experimental endocarditis due to S. aureus. In vitro, oxacillin, combined with either free amikacin or MiKasome, prevented the bacterial regrowth observed with aminoglycosides alone at 24 h of incubation. Rabbits with S. aureus endocarditis were treated with either oxacillin alone (50 mg/kg, given intramuscularly three times daily), oxacillin plus daily amikacin (27 mg/kg, given intravenously twice daily), or oxacillin plus intermittent MiKasome (160 mg/kg, given intravenously, a single dose on days 1 and 4). The oxacillin-alone dosage represents a subtherapeutic regimen against the infecting strain in the endocarditis model (L. Hirano and A. S. Bayer, Antimicrob. Agents Chemother. 35:685-690, 1991), thus allowing recognition of any enhanced bactericidal effects between oxacillin and either aminoglycoside formulation. Treatment was administered for either 3 or 6 days, and animals were sacrificed after each of these time points or at 5 days after a 6-day treatment course (to evaluate for posttherapy relapse). Left ventricular function was analyzed by utilizing serial transthoracic echocardiography during treatment and posttherapy by measurement of left ventricular fractional shortening. At all sacrifice times, both combination regimens significantly reduced S. aureus vegetation counts versus control counts (P < 0.05). In contrast, oxacillin alone did not significantly reduce S. aureus vegetation counts after 3 days of therapy. Furthermore, at this time point, the two combinations were significantly more effective than oxacillin alone (P < 0.05). All three regimens were effective in significantly decreasing bacterial counts in the myocardium during and after therapy compared to controls (P < 0.05). In kidney and spleen abscesses, all regimens significantly reduced bacterial counts during therapy (P < 0.0001); however, only the combination regimens prevented bacteriologic relapse in these organs posttherapy. By echocardiographic analysis, both combination regimens yielded a significant physiological benefit by maintaining normal left ventricular function during treatment and posttherapy compared with oxacillin alone (P < 0.001). These results suggest that the use of intermittent MiKasome (similar to daily conventional amikacin) enhances the in vivo bactericidal effects of oxacillin in a severe S. aureus infection model and preserves selected physiological functions in target end organs.  (+info)

Methicillin-resistant Staphylococcus aureus clonal types in the Czech Republic. (8/449)

Molecular surveillance studies have documented the extensive spread of methicillin-resistant Staphylococcus aureus (MRSA) clones. Studies carried out by Centro de Epidemiologia Molecular-Network for Tracking Gram-Positive Pathogenic Bacteria (CEM/NET) led to the identification of two international multidrug-resistant strains, which were designated as the Iberian and Brazilian MRSA clones and which were defined by multiple genomic typing methods; these included ClaI restriction digests hybridized with mecA- and Tn554-specific DNA probes and pulsed-field gel electrophoresis (PFGE). The genotypic characteristics of these clones are distinct: the Iberian clone is defined as mecA type I, Tn554 type E (or its variants), and PFGE pattern A (I:E:A), whereas the Brazilian clone is defined as mecA type XI (or its variants), Tn554 type B, and PFGE pattern B (XI:B:B). In this study, we characterized 59 single-patient isolates of MRSA collected during 1996 and 1997 at seven hospitals located in Prague and five other cities in the Czech Republic by using the methodologies mentioned above and by using ribotyping of EcoRI and HindIII digests hybridized with a 16S-23S DNA probe. The Brazilian MRSA clone (XI:B:B) was the major clone (80%) spread in two hospitals located in Prague and one located in Brno; the Iberian MRSA clone (I:E:A or its variant I:DD:A), although less representative (12%), was detected in two hospitals, one in Prague and the other in Plzen. Almost all the strains belonging to clone XI:B:B (45 of 47) corresponded to a unique ribotype, E1H1, whereas most strains of the I:E:A and I:DD:A clonal types (6 of 7) corresponded to ribotype E2H2.  (+info)

Discussion. Oxacillin resistance represents a major problem in the treatment of staphylococcal infections, especially because of the heterogenous expression of this resistance (Tveten et al., 2004). In the present study, oxacillin resistance was detected by PCR in 85 (82.5%) of the CoNS isolates studied. Similar results have been reported by Perez and dAzevedo (2008), who reported a rate of 78.4% of oxacillin-resistant CoNS strains using amplification of the mecA gene as the gold standard.. In addition to detection of the mecA gene, the reference methods recommended by the CLSI for the detection of oxacillin resistance in CoNS include the determination of MICs by agar and broth dilution methods, disk diffusion method, screening on Mueller-Hinton agar supplemented with 4 µg/ml oxacillin and 4% NaCl and, more recently, the cefoxitin disk diffusion test (NCCLS 1999, CLSI 2009). The present results show a sensitivity of 95.3% of the oxacillin disk diffusion method for the detection of MRCoNS. A ...
Cultures of the earliest isolate, JH1, and surveillance culture JH15 showed heterogeneous oxacillin resistance phenotypes when tested for population analysis profiles (PAPs). For the great majority of bacteria (>99.9%), oxacillin MICs were 0.75 μg/ml. The cultures also contained subpopulations of highly resistant cells for which oxacillin MICs were >400 μg/ml, but these subpopulations were present at a low (10−6) frequency in the cultures. A major increase in the oxacillin MICs for the majority of cells and a less heterogeneous PAP were detected in cultures of the isolates obtained next chronologically, JH2 and JH3; these isolates were recovered from the patient after a therapeutic regimen of imipenem treatment for noscomial pneumonia. Cultures of isolates recovered after this time (JH6 through JH14) showed heterogeneous oxacillin phenotypes; the MICs for the majority of cells were reduced to 1 to 3 μg/ml (Fig. 3).. Similar but much less extensive changes were also apparent with respect to ...
Antimicrobial resistance is increasing in nearly all health-care-associated pathogens. We examined changes in resistance prevalence during 1996-1999 in 23 hospitals by using two statistical methods. When the traditional chi-square test of pooled mean resistance prevalence was used, most organisms appear to have increased in prevalence. However, when a more conservative test that accounts for changes within individual hospitals was used, significant increases in prevalence of resistance were consistently observed only for oxacillin-resistant Staphylococcus aureus, ciprofloxacin-resistant Pseudomonas aeruginosa, and ciprofloxacin- or ofloxacin-resistant Escherichia coli. These increases were significant only in isolates from patients outside intensive-care units (ICU). The increases seen are of concern; differences in factors present outside ICUs, such as excessive quinolone use or inadequate infection-control practices, may explain the observed trends ...
In a previous study, we evaluated a mecA-specific assay that used a paramagnetic particle-labeled probe to separate the target-probe duplexes from solution and an acridinium ester-labeled probe to detect the hybridized mecA gene (11). However, the assay was limited by low sensitivity and high concentrations of organism were needed to obtain a valid result. The MecA bDNA assay affords a significant increase in sensitivity that is probably due to the inherent signal amplification properties of the assay. When the PCR was used as the gold standard, the bDNA assay was 100% sensitive and specific for both S. aureus and CNS.. Among 416 isolates, only 11 gave discrepant results between genotypic and phenotypic assays. Of these discrepant isolates, 10 contained themecA gene yet were phenotypically sensitive to oxacillin and 1 did not contain the mecA gene but was oxacillin resistant. Eight of these MecA+ isolates were later identified asS. epidermidis, and two were identified as S. hominis. The MecA− ...

The Staphylococcus aureus is an important pathogen bacteria actuating as an agent of a wide variety of infections, such as the superficials to the disseminates ones, its commonly find into hospitals ambient, assailing mainly immunosupress patients. Around 30% to 50% of people carries this agent in their nasal bone as part of their normal flora, occuring larger in hospitals workers. The S. aureus is also known for its high capacity of developing resistance to various antibiotic. Facing these considerations, the importance of nursing precaution and the infections control inside hospitals ambient, the purpose of this present study aimed to verify the rates of carriers of S. aureus in nursing students and the connection with the hospitals time involvement during graduation in the Faculty de Medicine de Botucatu - UNESP, embracing the 4 years of graduation college ...
This study evaluated oxacillin and cefoxitin DD and BMD testing for the detection of mecA-mediated β-lactam resistance in 100 contemporary human S. epidermidis isolates obtained from three geographical locations in the United States between 2015 and 2018. Nearly equal distributions of mecA-positive and -negative isolates were tested to ensure even distributions of resistant and susceptible isolates. Data generated from three MHA manufacturers (BD, Remel, and Hardy) and three CA-MHB manufacturers (Difco, BD, and Oxoid) demonstrated that cefoxitin DD using CLSI M100-S28 CoNS breakpoints and oxacillin DD using CLSI M100-S28 S. pseudintermedius/S. schleiferi breakpoints accurately predicted the presence and absence of mecA in S. epidermidis with 100% CA. Oxacillin BMD using CoNS breakpoints also yielded results that were highly accurate (with only one false-positive isolate), resulting in a ME rate of 2% and CA of 99%. While the zone of inhibition that was observed using Remel MHA was fainter than ...

Scanning electron micrograph of methicillin-resistant Staphylococcus aureus (MRSA) surrounded by cellular debris. Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium responsible for several difficult-to-treat infections in humans. It is also called multidrug-resistant Staphylococcus aureus and oxacillin-resistant Staphylococcus aureus (ORSA). MRSA is any strain of Staphylococcus aureus that has developed resistance to beta-lactam antibiotics, which include penicillins and cephalosporins. Strains unable to resist these antibiotics are classified as methicillin-sensitive Staphylococcus aureus, or MSSA. The development of such resistance does not cause the organism to be more intrinsically virulent than strains of Staphylococcus aureus that have no antibiotic resistance, but resistance does make MRSA infection more difficult to treat with standard types of antibiotics and thus more dangerous. MRSA is especially troublesome in hospitals and - Stock Image C028/3297
Mannitol salt agar (MSA) is nutrient agar that has a high concentration of salt (NaCl). Staphylococci are able to tolerate the high salt concentration and will grow to produce visible colonies. The high salt content inhibits the growth of many other pathogenic gram-positive and gram-negative bacteria. For this reason, we say that Mannitol salt agar (MSA) is selective for the Gram-positive bacteria Staphylococcus spp. since most other bacteria are unable to grow. ...

Obnoviteľné zdroje energie (OZE) sú také zdroje, ktoré sa prirodzene obnovujú v priebehu ich využívania. Ide o energetické toky, ktoré sa prirodzene vyskytujú v blízkosti zemského povrchu, zásoby, ktoré sa obnovujú aspoň tak rýchlo, ako sú spotrebuvávané. V ich čerpaní možno hypoteticky pokračovať ďalšie miliardy rokov - v podstate kým bude svietiť Slnko.

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 ...
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).

Youve more than likely heard of MRSA, or Methicillin-resistant Staphylococcus aureus, a strain of bacteria known as a superbug. It has also been referred to as multi-drug resistant and oxacillin-resistant, and by definition it is any strain of Staphyulococcus aureus bacteria that has grown resistant to what are known as beta-lactam antibiotics (which include the penicillins). Having grown resistant to powerful synthetic antibiotics, infection with this microbe is now responsible for many thousands of deaths annually - primarily in hospitals where patients are already immuno-compromised.. ...
