For a long time, Staphylococcus aureus has been always thought to be the only pathogenic species among Staphylococcus, while coagulase-negative staphylococci (CNS) were classified as contaminant agents. However, molecular techniques have shown that these microorganisms also possess enterotoxin-encoding genes. The aim of this study was to analyze the frequency of genes for staphylococcal enterot...

Trichinellosis is a helminthic infection where different species of Trichinella nematodes are the causative agents. Several molecular assays have been designed to aid diagnostics of trichinellosis. These assays are mostly complex and expensive. The genomes of Trichinella species contain certain parasite-specific genes, which can be detected by polymerase chain reaction (PCR) methods. We selecte...

introduction: drug resistant staphylococci are the most important agents of nosocomial infections. in this survey, effect of different antibiotics on these bacteria and their drug resistance was investigated. methods: the study included 500 strains of staphylococci. minimum inhibitory concentrations of all antibiotics was determined by the broth macro dilution technique and standard methods fro...

Staphylococcus aureus is a commensal and pathogenic bacterium that causes infections in humans and animals. It is a major cause of nosocomial infections worldwide. Due to increasing prevalence of multidrug resistance, alternative methods to eradicate the pathogen are necessary. In this respect, polyvalent staphylococcal myoviruses have been demonstrated to be excellent candidates for phage ther...

Evaluation of an immunochromatographic assay for rapid detection of penicillin-binding protein 2a in human and animal Staphylococcus intermedius group, Staphylococcus lugdunensis, and Staphylococcus schleiferi clinical isolate.

BACKGROUND Little is known about the impact of meticillin-resistant Staphylococcus aureus on patients with advanced cancer, such as its impact on the quality of life of this vulnerable group. To date, research on meticillin-resistant Staphylococcus aureus in the palliative care setting has had a quantitative focus. AIM The purpose of this study was to explore the impact of a meticillin-resist...

This study was carried out to determine the prevalence of sub-clinical mastitis, its etiological agents and their antibiogram in Murrah buffaloes at an organized farm. A total of 326 quarter milk samples were screened from 82 apparently healthy buffaloes. The percent prevalence of sub-clinical mastitis was found to be lower on the basis of SCC (>5x105/ml) alone (23.17) as compared to cultural e...

Staphylococci are Gram-positive bacteria which play an important role in infectious disease and are major causes of communityacquired and hospital-acquired infections. Strains of Staphylococcus aureus are reported as genomically and phenotypically highly heterogeneous; hence in-silico based comparison of genomic data on simple sequence repeats may provide valuable information for understanding ...

Objective Analyze nasal colonization by oxacillin-sensitive and oxacillin-resistant Staphylococcus aureus in people with HIV/AIDS (PWHA) at days 1 and7 of hospitalization. METHOD A prospective observational study conducted in a hospital in the countryside of the state of São Paulo. Nasal swab samples were collected and analyzed through microbiological identification, at days 1 and 7 of hospit...

conclusions in our study, inducible clindamycin resistance rate was 4%; so it is necessary to conduct d-test regularly by disc diffusion for this bacterium. resistance to erythromycin, clindamycin, ciprofloxacin and gentamicin was significantly higher in mrsa isolates than methicillin susceptible staphylococcus aureus (mssa), although the methicillin resistance prevalence was low. background st...
