Geographical variation in antimicrobial resistant Salmonella Schwarzengrund from chicken meat in Japan.
Chicken meat is a major source of foodborne salmonellosis. In Japan, fluoroquinolones and third-generation cephalosporins are the first- and second-choice treatments for Salmonella gastroenteritis, respectively. We investigated the prevalence and antimicrobial resistance of Salmonella in 154 chicken meat products from Hokkaido (42), Tohoku (45), Kanto (5), and Kyushu (62), Japan. Salmonella was isolated from 133 products (86.4%). High resistance rates were observed for streptomycin (56.5%), tetracycline (50.7%), and kanamycin (47.8%), while all isolates were susceptible to cefazolin, cefotaxime, gentamicin, ciprofloxacin, colistin, and chloramphenicol. The most common serovar, Salmonella Schwarzengrund (83.3%), showed clear regional differences in multidrug resistance: 100% in Kyushu, 41.5% in Tohoku, and 0% in Hokkaido. These findings highlight significant geographical variation in antimicrobial resistance among Salmonella Schwarzengrund isolates.
期刊介绍：
JVMS is a peer-reviewed journal and publishes a variety of papers on veterinary science from basic research to applied science and clinical research. JVMS is published monthly and consists of twelve issues per year. Papers are from the areas of anatomy, physiology, pharmacology, toxicology, pathology, immunology, microbiology, virology, parasitology, internal medicine, surgery, clinical pathology, theriogenology, avian disease, public health, ethology, and laboratory animal science. Although JVMS has played a role in publishing the scientific achievements of Japanese researchers and clinicians for many years, it now also accepts papers submitted from all over the world.
