The study aimed to investigate the phenotypic and genotypic identification of in vitro antimicrobial susceptibility of 21 Staphylococci (10 Staphylococcus aureus and 11 Coagulase Negative Staphylococci) isolated from bovine mastitis to 12 antimicrobial drugs frequently using in veterinary medicine in Algeria. Isolates of staphylococci from bovine mastitis were tested for antibiotics with disc-d...

BACKGROUND Staphylococcus aureus is a harmful pathogen known to express numerous virulence factors and cause severe infections. High levels of methicillin-resistant Staphylococcus aureus (MRSA) strains are one of the important healthcare problems because of the inefficient treatment of these infections. OBJECTIVES The purpose of the current study is to evaluate the incidence of the toxic shoc...

Introduction: In this study, using the phenotypic and genotypic methods, oxacillin susceptibility in Staphylococcus aureus (S. aureus) strains isolated from patients at two government hospitals in Ilam, Iran was tested. Materials and methods: Out of 200 S. aureus isolates from different human clinical specimens consisting of blood (31%), wound (20%), urine (21%), catheters (7%), sputum (12...

  Background and Objective: Methicillin resistance in Staphylococcus aureus is an increasingly important clinical problem. A chromosomal gene, mecA, mediates resistance to penicillinase-resistant penicillins such as methicillin and oxacillin in Staphylococcus aureus. We evaluated the validity of disk diffusion test by using oxacillin, methicillin an...

conclusions frequency of s. epidermidis was significantly lower, compared to other studies. presence rate of meca and susceptibility to linezolid and vancomycin did not show significant differences with other investigations, while resistant to trimethoprim-sulfamethoxazole was significantly lower compared to other investigations, and resistance to tetracycline was significantly higher in compar...

Detection of the mecA gene or PBP2a is considered the gold standard for detecting mecA-mediated methicillin resistance in staphylococci. Among available phenotypic methods, the Clinical and Laboratory Standards Institute (CLSI) has introduced the cefoxitin disk diffusion (DD) test for predicting the presence of mecA in S. aureus and CoNS, which is preferred over the oxacillin DD test. Automated...

The aim of this study was to determine the presence methicillin resistant staphylococci (MRS) in retail raw chicken meat samples sold Hatay. antimicrobial susceptibility isolates tested for 13 different antimicrobials by disc diffusion method and investigated resistance genes encoding (mecA), tetracycline (tetM, tetK), penicillin (blaZ), macrolide (ermA, ermC), lincosamide (lnuA) aminoglycoside...

Abstract The aim of this study was to investigate the rate resistance macrolide-lincosamide-streptogramin B (MLSB) antibiotics, mechanisms underlying and evaluate their relationship with virulence genes profiles 435 Bulgarian clinical isolates Staphylococcus aureus . highest observed penicillin (96.09%), followed by erythromycin clindamycin (34.02 22.76%, respectively). Of tested strains S. , 9...

We previously characterized over 100 Staphylococcus sciuri isolates, mainly of animal origin, and found that they all carried a genetic element (S. sciuri mecA) closely related to the mecA gene of methicillin-resistant Staphylococcus aureus (MRSA) strains. We also found a few isolates that carried a second copy of the gene, identical to MRSA mecA. In this work, we analyzed a collection of 28 S....

Background and Aims: Staphylococcus aureus is one of the important pathogens around the world. The present investigation was carried out to study the distribution of Staphylococcal Cassette Chromosome Mec (SCCmec) types and antibiotic resistance properties in methicillin-resistant Staphylococcus aureus isolated from Isfahan hospitals. Materials and Methods: A total of 250 clinical specimens ...
