staphylococci isolated from 98 mastitic cow’s milk samples were analyzed for the production of alpha,beta and delta-hemolysin on sheep, bovine and horse red blood cells and in vitro susceptibility to several antimicrobial agents. out of a total of 18 isolated strains, 100% demonstrated hemolytic activity either alone or in combined forms. among 8 isolates of s. aureus 3 isolates produced α/β an...

BACKGROUND: Lactobacilli are known as a valuable sourceof antimicrobial compounds and have a high potential of use infood biopreservation against food related microorganisms.OBJECTIVES: Antimicrobial potency of 63 dairy lactobacilliisolates against four highly important food-related microorganismswere evaluated. In addition, a new way in data organization wasintroduced, which led to a more info...

Antimicrobial control programs are widely used to decrease drug expenditures, but effects on antimicrobial resistance and outcomes for patients are unknown. When a requirement for prior authorization for selected parenteral antimicrobial agents was initiated at our urban, county teaching hospital, total parenteral antimicrobial expenditures decreased by 32%. Susceptibilities to all beta-lactam ...

Shigella sonnei isolates from southwestern Korea during the epidemic periods of 1998 to 2000 were genetically related. The antimicrobial susceptibilities of the outbreak-related isolates changed annually. All isolates carried class 2 integrons, and the outbreak-related isolates from 1999 also carried class 1 integrons. The antimicrobial susceptibilities of S. sonnei isolates are readily changed...

The antimicrobial susceptibilities of 78 strains of Clostridium difficile isolated from patients with and without gastrointestinal symptoms were determined and compared. Strains from patients with symptoms were more likely to show resistance to antibiotics. The antimicrobial susceptibilities of toxigenic and non-toxigenic strains were found to be similar.

INTRODUCTION Pseudomonas aeruginosa is one of the most important causes of nosocomial infection. Several reports indicated a correlation of antimicrobial usages and declined susceptibilities. In this report, we evaluated their relation in a tertiary care teaching hospital in Tokyo, Japan for 4 years. METHODS We evaluated the susceptibilities of 149 strains of P. aeruginosa isolated from blood...
