FK037, a new parenteral cephalosporin, is an oxime-type cephem antibiotic with a 1-hydroxyethyl-5-amino-pyrazole moiety at the 3 position. FK037 was evaluated for antimicrobial activity in vitro and in vivo. In vitro, FK037 was twofold or more active than ceftazidime, cefoperazone, cefotaxime, and ceftriaxone against Pseudomonas aeruginosa (MIC for 90% of the strains [MIC90] = 32 micrograms/ml)...

BACKGROUND The pathogenicity of staphylococcus aureus is dependent largely upon its ability to secrete a number of virulence factors, therefore, anti-virulence strategy to combat S. aureus-mediated infections is now gaining great interest. It is widely recognized that some plant essential oils could affect the production of staphylococcal exotoxins when used at subinhibitory concentrations. Per...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) clones pose a significant threat to hospitalised patients because the bacteria can be transmitted by asymptomatic carriers within healthcare facilities. To date, nothing is known about the prevalence of S. aureus and MRSA among healthcare workers in Madagascar. The objective of our study was to examine the prevalence and clonal epide...

A latex agglutination test (SeroSTAT Staph; Scott Laboratories, Fiskeville, R.I.) and two hemagglutination tests (Staphyloslide; BBL Microbiology Systems, Cockeysville, Md.; and Hemastaph; Remel, Lenexa, Kans.) were compared with the slide coagulase (SC) and tube coagulase (TC) tests at room temperature (22 to 25 degrees C) and at 37 degrees C for the rapid identification of Staphylococcus aure...

OBJECTIVES To measure prevalence of Staphylococcus aureus colonization in household contacts of children with acute S aureus skin and soft tissue infections (SSTI), determine risk factors for S aureus colonization in household contacts, and assess anatomic sites of S aureus colonization in patients and household contacts. DESIGN Cross-sectional study. SETTING St Louis Children's Hospital Em...

infectious diseases are one of the most common causes of morbidity and mortality and the spread of resistant microorganisms is playing a significant role in this regard. the purpose of this study was to assess the trend in antimicrobial resistance of gram-positive bacteria at the main referral teaching hospital in tehran during a 4-year period. all patients' biological isolates such as blood, u...

654 Virulence Volume 4 issue 7 Staphylococcus aureus infects millions worldwide. Methicillin-sensitive and methicillin-resistant S. aureus (MSSA and MRSA) isolates may closely share virulence determinants through related clonal complexes. The purpose of this pilot study was to assess the epidemiology of S. aureus colonization in pregnant women in a community-acquired MRSA endemic area at the ti...

Background: Food poisoning due to the bacteria is a big global problem in economically and human's health. This problem refers to an illness which is due to infection or the toxin exists in nature and the food that we use. One of the most important productive factors is Staphylococcus aureus. In general different strain of S. aureus produces several enterotoxins like: SEA, SEB, SEC. So, the exi...

BACKGROUND The epidemiology of staphylococcal colonization and community-associated methicillin-resistant Staphylococcus aureus (MRSA) is changing, and little is known from the national perspective. OBJECTIVE To describe the U.S. epidemiology of S. aureus nasal colonization, compare risk factors for colonization with methicillin-sensitive S. aureus (MSSA) versus MRSA, and compare antibiotic r...
