Virulence Genes, Biofilm Production and Antibiotic Susceptibility in Trueperella pyogenes Isolated from Cattle
ABST RACT Trueperella pyogenes (formerly Arcanobacterium pyogenes) is a commensal bacterium present on the upper respiratory and urogenital tract mucosa of domestic and wild animals. It is also the most common opportunistic pathogen and isolated from the infections of cattle such as mastitis, metritis, arthritis and pneumonia. The aim of this study was to determine virulence genes (plo, nanH, n...
متن کاملDetecting Virulence Factors and Antibiotic Resistance Pattern of Trueperella Pyogenes Isolated from Bovine Mastitic Milk
Backgrounds and Aims: Mastitis is a mammalian disease which is considered important due to its potential economic damages. Trueperella pyogenesis is one of the important opportunistic pathogens of the mammary glands of cattle. This bacterium can produce acute mastitis infection in dairy cattle. In fact, this bacterium has several virulence genes which contribute to its pathogenicity. Therefore,...
متن کاملPhenotypic antimicrobial susceptibility and occurrence of selected resistance genes in gram-positive mastitis pathogens isolated from Wisconsin dairy cows.
In the United States, few intramammary antimicrobials exist that are approved for treatment of bovine mastitis; thus, ensuring judicious use of these products is a priority. The objectives of this study were to determine phenotypic susceptibility and presence of selected antimicrobial resistance genes from staphylococci, streptococci, and streptococcal-like organisms recovered from cases of cli...
متن کاملEtiology and antimicrobial susceptibility of udder pathogens from cases of subclinical mastitis in dairy cows in Sweden
BACKGROUND A nationwide survey on the microbial etiology of cases of subclinical mastitis in dairy cows was carried out on dairy farms in Sweden. The aim was to investigate the microbial panorama and the occurrence of antimicrobial resistance. Moreover, differences between newly infected cows and chronically infected cows were investigated. METHODS In total, 583 quarter milk samples were coll...
متن کاملCharacteristics of staphylococci isolated from clinical and subclinical mastitis cows in Shahrekord, Iran
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...
