Development of an indirect ELISA for bovine mastitis using Sip protein of Streptococcus agalactiae
The sip gene encoding for a conserved highly immunogenic surface protein of Streptococcus agalactiae was amplified using polymerase chain reaction (PCR) and subcloned into prokaryotic expression vector pET32a (+) and expressed as a recombinant protein in E. coli BL21 (DE3). An indirect enzyme linked immunosorbent assay (ELISA) was developed using the purified Sip protein as a coating antigen, w...
متن کاملImmunizing mice using different combination antigens of the PI-2a fimbria subunit of Streptococcus agalactiae
Background: Streptococcus agalactiae is the main causal pathogen of bovine mastitis (BM), causing considerable economic loss to the dairy industry worldwide. Vaccines against S. agalactiae play an important role in preventing disease. Aims: The aim of this study was to evaluate the immunoprotection of S. agalactiae pilus isla...
متن کاملComparative genomics and the role of lateral gene transfer in the evolution of bovine adapted Streptococcus agalactiae.
In addition to causing severe invasive infections in humans, Streptococcus agalactiae, or group B Streptococcus (GBS), is also a major cause of bovine mastitis. Here we provide the first genome sequence for S. agalactiae isolated from a cow diagnosed with clinical mastitis (strain FSL S3-026). Comparison to eight S. agalactiae genomes obtained from human disease isolates revealed 183 genes spec...
متن کاملPrevalence 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 کاملBiofilm formation, hemolysin production and antimicrobial susceptibilities of Streptococcus agalactiae isolated from the mastitis milk of dairy cows in Shahrekord district, Iran
Streptococcus agalactiae is a major contagious pathogen causing bovine sub-clinical mastitis. The present investigation was carried out to determine some phenotypic characteristics of the S. agalactiae strains isolated from bovine mastitis cases in dairy cows of Shahrekord in the west-center of Iran. One hundred eighty California mastitis test (CMT) positive milk samples were ...
