OBJECTIVES We investigated the antimicrobial susceptibilities and resistance mechanisms of cattle-adapted Salmonella enterica serovar Dublin isolated in Japan in the past 30 years. This study is an example of evaluation of the impact of introduction of antimicrobials in veterinary medical practice on the selection of resistance in S. enterica. METHODS The antimicrobial susceptibilities and pr...

We investigated the susceptibilities against 7 antimicrobial agents in Campylobacter jejuni and C. coli isolates from food-producing animals in 2004. In comparison with the results of past surveillance, no significant difference was observed in resistance rates against all of the antimicrobials tested in Campylobacter isolates. However, slight increase of erythromycin (EM) resistance was found ...

The purpose of this study was to evaluate antibiotics effective for periodontopathic bacteria as chemotherapeutic agents for periodontal diseases. Antimicrobial activities of ten agents were evaluated by determinating minimal inhibitory concentrations against six periodontopathic bacterial species ( Bacteroides gingivalis, B. melaninogenicus ss intermedius, Fusobacterium nucleatum, Eikenella co...

Facklamia spp. are gram-positive cocci, arranged in short chains or diplos, and resemble viridans streptococci on 5% sheep blood agar. Eighteen strains representing four species of Facklamia were isolated from blood cultures, an abscess, bone, cerebrospinal fluid, gall bladder, vaginal swab, and one unknown source. Cultures were tested against 15 antimicrobial agents by using the broth microdil...

Monitoring trends in antimicrobial drug-resistant Neisseria gonorrhoeae is a critical public health and global health security activity because the number of antimicrobial drugs available to treat gonorrhea effectively is rapidly diminishing. Current global surveillance methods for antimicrobial drug-resistant N. gonorrhoeae have many limitations, especially in countries with the greatest burde...

Distillers grains, a coproduct of ethanol production from cereal grains, are composed principally of the bran, protein, and germ fractions and are commonly supplemented in ruminant diets. The objective of this study was to assess the effect of feeding wet distillers grains with solubles (WDGS) and monensin and tylosin on the prevalence and antimicrobial susceptibilities of fecal foodborne and c...

background the treatment of acinetobacter baumannii infections is difficult. carbapenems, sulbactam, and colistin are the most effective antibiotics. objectives the aim of this study was to evaluate the susceptibilities of genotypically different a. baumannii isolates to sulbactam, amikacin, netilmicin, meropenem, tigecycline and colistin. patients and methods isolates from various clinical sam...
