OBJECTIVE To determine rate of nasal colonization in Patients suffering from bacteraemia caused by methicillin resistant Staphylococcus aureus. METHODS This descriptive cross sectional study was carried out in a tertiary ca re, University Teaching Hospital (Shaikh Zayed Hospital, Lahore) from October 2010 to August 2011. Nasal swabs were taken from patients suffering from MRSA bacteraemia and...

Extension of drug resistant Staphylococcus aureus strains is one of the problems of modern society. Presence of methicillin-resistant Staphylococcus aureus (MRSA) in HIV-infected individuals is an important cause of severe infections. Therefore, the main goal of this study was to determine the prevalence rate of MRSA carriage rate among HIV patients referring to the Shiraz HIV referral center (...

Abstract  Background: Methicillin-resistant Staphylococcus aureus (MRSA) has been recognized as a matter of antibiotic resistance that is largely developed amongst common foodborne pathogens. MRSA is being considered as an important worldwide health threat and causes considerable concern to clinicians, food products manufacturers, governments and also consumers. OBJECTIVES: The objective of thi...

An in vivo experiment was conducted to evaluate the effects of tetracycline and zinc on pig colonization and transmission of methicillin-resistant Staphylococcus aureus (MRSA) sequence type (ST) 398. Eight piglets naturally colonized with MRSA ST398 and 8 MRSA-negative piglets of the same age and breed were assigned to three groups treated with tetracycline and zinc (Group 1), zinc (Group 2) or...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) is a nosocomial (hospital-acquired) pathogen of exceptional concern. It is responsible for life-threatening infections in both the hospital and the community. AIMS To determine the frequency of MRSA misidentification in hospitals in Tripoli, Libya using current testing methods. METHODS One hundred and seventy S. aureus isolates p...

Background: Nasal carriage of Staphylococcus aureus has a key role in the epidemiology and pathogenesis of infection. In this study we aimed to investigate the occurrence of the methicillin resistant Staphylococcus aureus (MRSA )and mecA gene among healthy primary school boys in north of Iran.Material and methods: This cross-sectional study was conducted from January 2017 to July 2017 in Sari l...

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is resistant to most antibiotics and is an important pathogen of nosocomial infections. Colonization with MRSA is no longer limited to hospitalized patients or persons with predisposing risk factors and at present there are several strains of community-acquired MRSA (CA-MRSA). Objectives: The aim of this study was to determine the p...

BACKGROUND The prevalence of community-associated methicillin-resistant Staphylococcus aureus [CA-MRSA] is unknown in Oman. METHODS Nasal and cell phones swabs were collected from hospital visitors and health-care workers on sterile polyester swabs and directly inoculated onto a mannitol salt agar containing oxacillin, allowing growth of methicillin-resistant microorganisms. Antibiotic suscep...

In a recent letter, Simor et al. reported results obtained by using oxacillin resistance screening agar base (ORSAB; Oxoid Limited, Basingstoke, England) for the detection of methicillin-resistant Staphylococcus aureus (MRSA) from clinical specimens (A. E. Simor, J. Goodfellow, L. Louie, and M. Louie, Letter, J. Clin. Microbiol. 39:3422, 2001). ORSAB is a modification of a mannitol-salt agar su...

BACKGROUND To study the nasal carriage rate of Staphylococcus aureus (S. aureus) (including methicillin-resistant strains) in secondary school community of the urban and rural districts of the Kurdistan region of Iraq, a cross-sectional population based survey was carried out in the city Duhok and rural areas of Amedya, Akre and Zakho. METHODS Nasal swabs were obtained from nostrils of 509 st...
