Biological properties of staphylococci derived from cats and dogs

Abstract

Dogs and cats play an important role in human life, and they are often a source of zoonotic agents. The purpose of the study was to investigate domestic dogs and cats for staphylococcus carriers and to study their biological properties, biofilm ability, and antibiotic resistance in isolated cultures. Staphylococci were detected in 54% of all samples selected 25 cultures of Staphylococcus spp. Plasma coagulation reaction was negative in 100% of strains isolated from cats, and positive in 2 strains isolated from dogs (18%). Lecithinase activity was shown by 85.8% of strains isolated from cats and 72.8% from dogs. 71.5% of the strains isolated from cats and 63.7% from dogs had the ability to hemolysis. Mannitol was fermented in 50.0% of strains isolated from cats and 54.6% from dogs. 78.6% of strains isolated from cats and 91.0% isolated from dogs grew on crystal violet lactose agar in the form of blue colonies. Simultaneously showed lecithinase activity, hemolysis, fermented mannitol and grew on crystal violet lactose agar 28.5% isolated from cats and 27.2% isolated from dogs strains. The derived strains from cats and dogs had multiple resistance to Oxacillin, two or more groups of antibiotics. All 100% of the isolated isolates from dogs had a high (OD> 1.0) ability to form a biofilm. Only 21.4% of strains isolated from cats had a medium (OD> 0.5 1.0) ability to form a biofilm.
