Objective To determine the occurrence and antibiotic resistance of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) isolates. Methods used In 2003-2005, consecutive samples of nasal, throat, eye, ear and genitourinary tract swabs, swabs of wound infections and soft and skin tissue infections and samples of sputum obtained from outpatients submitted to the Laboratory with cl...

Staphylococcus aureus is naturally present in the nasal membranes and skin of warm blooded animals including human beings. It can grow in aerobic and anaerobic conditions, forming grape-like clusters. It causes a range of infections from mild, such as skin infections and food poisoning to life threatening, such as pneumonia, sepsis, oseteomyelitis and infectious endocarditis. Methicillin Resist...

Microbiological studies were carried out in a small poultry farm in a Community in South West Nigeria following a report of acute diarrhea in 6-week old broilers, catarrh and cough in the poultry attendants. Nasal swabs were collected from 25 symptomatic and 5 asymptomatic attendants. Swabs were collected from the cloacae of 100 birds with diarrhea. Twenty-five (100%) symptomatic attendants car...

Objective: To identify the Methicillin Resistant Coagulase Negative Staphylococci (MRCONS) and Methicillin Resistant Staphylococcus aureus (MRSA) from clinical specimens and their antimicrobial susceptibility patterns. Methodology: All strains were recovered from clinical specimens according to 0.5 McFarland standard inoculated on Muller Hinton agar. Antibacterial susceptibility was tested by d...

Sir—In their study of the community prevalence of carriage of methicillin-resistant Staphylococcus aureus (MRSA) among San Francisco's urban poor, Charlebois et al. [1] found an overall prevalence of MRSA carriage of 2.8%. Injection drug use and prior hospitalization within 1 year were significant multivariate risk factors for MRSA acquisition. During the spring of 2000, a similar point prevale...

Limited data exist from the Gulf Cooperation Council states on the prevalence and population dynamics of Staphylococcus aureus colonizing livestock or contaminating retail meat. This study was designed to determine the presence and genetic characteristics of Staphylococcus aureus isolated from raw retail meat sold in Riyadh, Saudi Arabia. Over a period of 9 months, different raw retail meat typ...

background and objectives:   staphylococcus aureus is one of the main causatives of bovine mastitis. resistance of some strains to methicillin, can complicate the treatment of its infections. on the other hand, enterotoxin production is also im- portant. therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in s. aureus isolates caused bovine m...

Background: Methicillin resistant Staphylococus Aureus (MRSA) is a cause of ‎nosocomial infections at intensive care unit (ICU), which imposes a high mortality and ‎morbidity on the health care systems.‎ The objective of this study was to evaluate the role of MRSA in patients with clinically ‎suspected ventilator associated pneumonia (VAP) in toxicological ICU admitted ‎patients.Methods: This ...

There is renewed interest in the hospital environment as a potentially important factor for cross-infection with methicillin-resistant Staphylococcus aureus (MRSA) and other nosocomial pathogens. The aim of this study was to evaluate the effectiveness of a portable high-efficiency particulate air (HEPA)-filtration unit (IQAir Cleanroom H13, Incen AG, Goldach, Switzerland) at reducing MRSA envir...

Methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) present major challenges (1–4). Our objective was to define the frequency of MRSA and VRE fecal carriage in healthy children and their mothers to evaluate potential reservoirs and opportunities for reducing transmission. After approval by the Washington University Human Research Protection Office, info...
