Prevalence of Virulence Factors and Antimicrobial Resistance of Streptococcus agalactiae and Streptococcus uberis in Ruminant Sub-clinical Mastitic Milk in Iran
Background and Aims: The aim of this study was to determine the virulence and antibiotic resistance properties of Streptococcus agalactiae (S. agalactiae) and Streptococcus uberis (S. uberis) isolated from the ruminant’s sub-clinical mastitic milk in Iran. Materials and Methods: Positive samples in the CMT test were cultured and S. agalactiae and S. uberis have been identified using bi...
متن کاملGenetic patterns of Streptococcus uberis isolated from bovine mastitis.
The aim of this study was to evaluate the genotypic relationships among 40 Streptococcus uberis isolated from bovine mastitis by using pulsed-field gel electrophoresis (PFGE). Additionally, the association between PFGE patterns and virulence profiles was investigated. The isolates exhibited 17 PFGE patterns. Different strains were found within and among herds; however, a low number of isolates ...
متن کاملPhenotypic and genotypic characterization of Streptococcus uberis isolated from bovine subclinical mastitis in Argentinean dairy farms.
The aim of this study was to investigate the phenotypic and genotypic characteristics of Streptococcus uberis isolated from subclinical mastitis (SCM) cases, and to examine the possible association between both characteristics. A total of 32 S. uberis were isolated from 772 quarter milk samples (SCM > 250,000 cells/ml) collected from 195 cows selected randomly from 18 dairy farms located in Arg...
متن کاملMolecular detection of virulence genes and multi-drug resistance patterns in Escherichia coli (STEC) in clinical bovine mastitis: Alborz province, Iran
The aim of this study was to identify virulence genes and antimicrobial resistance of Escherichia coli isolated from bovine clinical mastitis in dairy herds in Iran. Sampling was done from 86 inflamed quarters of dairy cows in 8 commercial farms of Alborz province, Iran in summer 2015. Shiga toxin-producing E. coli (STEC) virulence genes were detected by multiplex PCR and multi-drug resistance ...
متن کاملCorrelation of hypothetical virulence traits of two Streptococcus uberis strains with the clinical manifestation of bovine mastitis
Streptococcus uberis is a common cause of clinical and subclinical mastitis in dairy cattle. Several virulence mechanisms have been proposed to contribute to the species' ability to cause disease. Here, virulence characteristics were compared between S. uberis strains FSL Z1-048, which consistently caused clinical mastitis in a challenge model, and FSL Z1-124, which consistently failed to cause...
