background and objectives:   staphylococcus aureus is one of the main causatives of bovine mastitis. resistance of some strains to methicillin, can complicate the treatment of its infections. on the other hand, enterotoxin production is also im- portant. therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in s. aureus isolates caused bovine m...

Staphylococcus aureus is a harmful bacterium that often contaminates milk; hence it believed to become severe health risk for humans . S. resistant β‑lactam drugs can be termed methicillin (MRSA). Dairy farms have high incidence of MRSA infections due the repeated use same medicines on dairy cows and physical contact between farmers during milking. This study looked in cow milk farmer hand swab...

The in vitro antibacterial activity of nine cephalosporins (cephalothin, cephaloridine, cephalexin, cefazolin, cefamandole, cefuroxime, cefatrizine, cefoxitin, and cefazaflur) was determined against 344 strains of Enterobacteriaceae and 99 nonfermentative gram-negative bacilli. Cefamandole, cefazaflur, and cefuroxime were the most active cephalosporins against the Enterobacteriaceae (with the e...

background and objectives: methicillin-resistant staphylococcus aureus (mrsa) is a well-known pathogen with a worldwide distribution. given the increasing rate of mrsa infections, implementing of reliable, accurate and rapid testing for diagnosis of mrsa is necessary. the aim of this study was to compare four diagnostic methods for detection of mrsa isolates. materials and methods: from decembe...

The in vitro susceptibility of 155 strains of anaerobic bacteria to five cephalosporin antibiotics was tested. Cefoxitin was the most active against 33 isolates of Bacteroides fragilis; 82% of the strains were sensitive at 16 mug/ml. At 64 mug/ml cefazolin and cephaloridine were also generally effective. Cephalothin and cephalexin were relatively inactive versus B. fragilis. Cefoxitin, cephalor...

The in vitro susceptibility of 157 anaerobic bacteria to imipenem was compared with that to cefoxitin, latamoxef (moxalactam) and clindamycin. The isolates were cultured from clinical specimens submitted to Tufts Anaerobic Laboratory between January 1981 and March 1983. Two strains of Bacteroides fragilis only, were highly resistant to imipenem. The incidence of cefoxitin resistance in the Bact...
