Antibiotic Susceptibility and Plasmid Profiles of Staphylococcus aureus Strains Isolated from Bovine Subclinical Mastitis in Tabriz, Iran
ABSTRACT Background and Objectives: Mastitis caused by Staphylococcus aureus is a widely distributed disease in cattle, goats and sheep. The infection is often subclinical in cattle, leading to reduced milk production and quality, but acute catarrhal or even gangrenous inflammation may also occur. The aim of this study was to investigate resistance of S. au...
متن کاملDiagnosis and characteristics of contagious mastitis caused by Staphylococcus aureus and Streptococcus agalactiae
With rapidly increasing herd sizes, focus on contagious udder pathogens becomes important. Based on a yearly test of bulk tank milk in Danish dairy herds, the prevalence of herds infected with Streptococcus agalactiae (S. agalactiae) increased from 2 % in 2000 to 7 % in 2010, while approximately 90 % of the herds were positive for Staphylococcus aureus (S. aureus) (Katholm, et al., 2012). The r...
متن کاملIn vitro susceptibility of Staphylococcus aureus strains isolated from cows with subclinical mastitis to different antimicrobial agents
Sensitivity to commercial teat dips (nonoxinol-9 iodine complex and chlorhexidine digluconate) of 56 Staphylococcus (S.) aureus strains isolated from quarter milk samples of various German dairy herds treated with different teat dipping schemes was investigated in this study. The minimum inhibitory concentration was determined using a broth macrodilution method according to the German Veterinar...
متن کاملIdentification of Streptococcus canis isolated from milk of dairy cows with subclinical mastitis.
Streptococcus canis was isolated from 31 milk samples from 11 cows in a dairy herd (with 49 lactating cows) affected by subclinical mastitis in north Rhine-Westphalia, Germany. Thirty-one isolates from the infected udder quarters were further characterized for their phenotypic and molecular properties. Most isolates (83.9%) produced alpha-galactosidase, and all were negative for beta-d-glucuron...
متن کاملHigh Frequency of biofilm related genes (icaD, fnbA, icaA and clfA) among Staphylococcus aureus isolated from bovine with subclinical mastitis
Background and aim: Regarding to the importance of Staphylococcus aureuscolonization in bovine mastitis and the role of biofilm in its pathogenesis, the aim of the present study were to assessment of biofilm production and identification of biofilm related genes among S. aureus isolated from bovine with subclinical mastitis. Materials and Methods: In this cross-sectional study, a total of 502 m...
