Abstract :The objectives of this study were to identify staphylococci isolated from different animal clinical samples, to examine some of the virulence factors in the isolates, to determine relationships between these virulence factors and coagulase positive Staphylococcus insert ignore into journalissuearticles values(CoPS);/coagulase negative Staphylococcus insert ignore into journalissuearticles values(CoNS); strains. A total of 180 strains of Staphylococcus spp. were isolated from bovine mastitis, dogs with otitis externa and chickens with various infections. The isolates were identified as S. aureus insert ignore into journalissuearticles values(29.4%);, S. hyicus insert ignore into journalissuearticles values(16.7%);, S. intermedius insert ignore into journalissuearticles values(3.9%);, S. chromogenes insert ignore into journalissuearticles values(16.1%);, S. lentus insert ignore into journalissuearticles values(13.3%);, S. epidermidis insert ignore into journalissuearticles values(11.1%);, S. simulans insert ignore into journalissuearticles values(7.8%); and S. haemolyticus insert ignore into journalissuearticles values(1.7%);. The rate of positiveness for deoxyribonuclease insert ignore into journalissuearticles values(DNase); test, thermonuclease insert ignore into journalissuearticles values(TNase); test, presence of the capsule, slime and biofilm formation, hemolysis, and hemagglutination tests for CoPS strains were 42.2%, 43.3%, 53.3%, 77.8%, 74.4%, 58.9%, 46.7%, and for CoNS strains were 54.4%, 5.6%, 13.3%, 44.4%, 36.7%, 28.9% and 41.1%, respectively. The virulence factors which were investigated were determined CoNS and CoPS strains. Thus, it was thought that CoNS strains might be as dangerous as CoPS strains for both animals and humans.
