Methicillin-resistant Staphylococcus aureus in pork production shower facilities.

بررسی شیوع کلونیزاسیون استافیلوکوک اورئوس مقاوم به متی سیلین و وانکومایسین در نازوفارنکس در بیمارستان امیراعلم، سال 1383

Background: Staphylococcus aureus is one of the most common causes of nosocomial infections with high morbidity and mortality rate. Traditionally, methicillin resistant staphylococcus aureus has been considered a major nosocomial pathogen in healthcare facilities, but in the past decade, it has been observed emerging in the community as well. Informations regarding hospital microbial colonizati...

Virulence Factors of Staphylococcus aureus Isolated from Korean Pork bulgogi: Enterotoxin Production and Antimicrobial Resistance

The aim of this study was to investigate the antimicrobial resistance profiles of and the enterotoxin gene distribution in 4 strains of Staphylococcus aureus (S10-2, S10-3, S12-2, and S13-2) isolated from 90 bulgogi samples. The S. aureus enterotoxin H gene (seh) was found in all the strains, while the S. aureus enterotoxin A gene (sea) was found only in 3 of the 4 strains. The S10-2 strain exp...

Biofilm Formation and Detection of IcaAB Genes in Clinical Isolates of Methicillin Resistant Staphylococcus aureus

Objective(s) Methicillin-resistant Staphylococcus aureus (MRSA) is an important cause of nosocomial and community infections. Biofilm formation, mediated by a polysaccharide intercellular adhesin (PIA) and encoded by the ica operon, is considered to be an important virulence factor in both S. epidermidis and S. aureus. However, the clinical impact of the ica locus and PIA production is less w...

Survival of methicillin-resistant Staphylococcus aureus during various thermal lethality processes used to manufacture pork products

Isolation and characterization of methicillin-resistant Staphylococcus aureus strains from Louisiana retail meats.

We investigated the prevalence of Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) in 120 retail meat samples from 30 grocery stores in Baton Rouge, LA. S. aureus strains were recovered from 45.6% of pork samples and 20% of beef samples, whereas MRSA strains were isolated from six meat samples (five pork samples and one beef sample). The MRSA isolates were of two strain types (c...
