conclusions the present study showed a high prevalence of aminoglycoside-resistance genes among mrsa isolates in two cities in iran. results the results of drug susceptibility testing showed that the highest rate of resistance was against erythromycin in tehran (84.4%) and gentamicin (71.7%) in sari. all isolates were sensitive to vancomycin, and all strains harbored the meca gene. the aac (6’)...

Surgical site infections caused by bacteria that are resistant to multiple classes of antimicrobials are an important and increasing problem in veterinary medicine. Organisms such as methicillin-resistant staphylococci, extended spectrum beta-lactamase Enterobacteriaceae and multi-drug resistant Enterococcus, Acinetobacter and Pseudomonas spp. are among the current concerns; however, the emerge...

Background: The spread of resistant bacteria has caused serious concern worldwide. multidrug-resistant (MDR) and extensive drug-resistant (XDR) limits the choice antibiotics, making available antibiotics less effective. Objectives: This study aimed to investigate resistance patterns seven global threatening organisms announced by Centers for Disease Control Prevention (CDC) one year in Iran, ca...
