Polymorphism in spa gene of Staphylococcus aureus from bovine subclinical mastitis
AIM The virulence-associated protein-A of Staphylococcus aureus, encoded by spa gene shows a variation in length in different strains. In this study, the spa gene variation in S. aureus strains was studied which were isolated from subclinical cases of bovine mastitis. MATERIALS AND METHODS About 38 isolatesof S. aureus were recovered from Holstein-Friesian (HF) crossbred (n=16) and Rathi catt...
متن کاملComparative sequence analysis of spa gene of Staphylococcus aureus isolated from bovine mastitis: characterization of an unusual spa gene variant.
The protein A encoding gene spa of four Staphylococcus aureus strains isolated from bovine clinical mastitis was amplified by PCR and sequenced. The four strains were selected after an initial screening of spa gene of 41 strains isolated from mastitic cows and were subjected to detailed investigations. According to the sequencing results the spa gene of three strains (M1, M2, M3) appeared with ...
متن کاملAntibiotic 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 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...
متن کاملIdentification of Toxic Shock Syndrome Toxin-1 (TSST-1) gene in Staphylococcus aureus isolated from bovine mastitis milk
Staphylococcus aureus is a major causative pathogen of clinical and subclinical mastitis of dairy domestic ruminants. This agent produces a variety of extracellular toxins and virulence factors including Toxic Shock Syndrome Toxin-1 (TSST-1) which is the major cause of Toxic Shock Syndrome (TSS). In this study 58 S. aureus isolates obtained from 9 dairy herds in East and West Azerbaijan provinc...
