Bacteriophages for Controlling spp. Pathogens on Dairy Cattle Farms: In Vitro Assessment.

Pathogenic spp. strains are significant agents involved in mastitis and in skin and limb infections in dairy cattle. The aim of this study was to assess the antibacterial effectiveness of bacteriophages isolated from dairy cattle housing as potential tools for maintaining environmental homeostasis.

Serotypes, Antibiotic Susceptibility, Genotypic Virulence Profiles and SpaA Variants of Strains Isolated from Pigs in Poland.

The aim of the study was phenotypic and genotypic characterization of strains isolated from diseased pigs in Poland and comparison of the SpaA (Surface protective antigen A) sequence of wild-type strains with the sequence of the R32E11 vaccine strain. The antibiotic susceptibility of the isolates was assessed using the broth microdilution method. Resistance genes, virulence genes, and serotype determinants were detected using PCR.
