In disc diffusion tests, hyper-producers of penicillinase may show small methicillin or oxacillin
zones of inhibition, whereas most true methicillin/oxacillin-resistant isolates give no zone.12
The most prevalent lineage USA100 tended to present multidrug resistance, with high MIC values for oxacillin
, vancomycin, and daptomycin.
Antibiotics use were; oxacillin
(1ug), cefoxitin (30 ug), ceftriaxone (30 ug), amikacin (30 ug), co-amoxiclav (30 ug), azithromycin (15ug), ciprofloxacin (30 ug), vancomycin (30 ug), and clindamycin (2 ug).
A large number of poultry meal samples contained bacteria that were resistant to oxacillin
, aziocillin, ceftriaxone, streptomycin, bacitracin, cefuroxime, tetracycline and amoxicillin/clavulanic acid, whereas few samples were contaminated with bacteria resistant to ciprofloxacin, kanamycin and sulfa drugs.
aureus were put to antibiotic susceptibility against Oxacillin
and Ampicillin (Penicillin), Cefoxitin (Cephalosporin), and Vancomycin (Glycopeptide).
Owing to improve in vitro stability, oxacillin
, a penicillinase-resistant semi-synthetic penicillin, is commonly used in veterinary microbiology laboratories to detect methicillin resistant staphylococci (COLE et al., 2006).
Staphylococcus aureus were resistant to most of the antibiotics such as azithromycin, penicillin, doxycycline, ciprofloxacin, tetracycline, gentamicin, ofloxacin, chloramphenicol, ampicillin and oxacillin
. Ninety percent of the Staphylococcus aureus isolated were methicillin resistant S.
Our study is planned to know the prevalence of MRSA among different clinical samples received in laboratory with the aim to compare the PCR of the mecA gene with four phenotypic methods--cefoxitin disc diffusion test, oxacillin
disc diffusion test and MIC of oxacillin
by E test and screen agar test for detection of MRSA.
The farmer was prescribed ciprofloxacin multiple times; this could have contributed to emergence of borderline oxacillin
While forty-four of eighty strains were found to be resistant to oxacillin
, thirteen of these strains were found to be serogroup 19.
The overall resistance to clindamycin, vancomycin, trimethoprim-sulfamethoxazole, tetracycline, penicillin G, oxacillin
, and cefoxitin was 23.9%, 2.2%, 30.4%, 41.3%, 71.7%, 6.5%, and 4.4%, respectively.
aureus ATCC43300 Oxacillin
resistant strain were used as control strains.
His antibiotics were tailored to oxacillin
2 gm IV every 4 hours as blood and sputum cultures revealed growth of methicillin-susceptible Staphylococcus aureus.
ciprofloxacin, clindamycin and methicillin (oxacillin
A dilution series was prepared using oxacillin
