COAGULASE-NEGATIVE STAPHYLOCOCCUS SCHLEIFERI AS AN ETIOLOGICAL FACTOR OF INFECTIOUS DERMATITIS IN DOGS

Abstract

The purpose of the work was to establish the cause of mass chronic dermatitis in Central Asian sheepdog dogs. The study sample consisted of dogs kept in enclosures and exhibiting symptoms of alopecia and papules with bloody contents on their faces and chests. The contents of the papules were collected using a sterile syringe for analysis and identification of the cause of the disease. This was done in order to determine the cause of the disease. The collected contents were then directly cultured on nutrient media. As a result, a pure culture of Staphylococcus schleiferi was isolated from all affected dogs. The article describes its cultural, biochemical properties and sensitivity to antibiotics. The zoonotic potential of the pathogen has been proven by other authors, as well as by isolating a pure culture of Staphylococcus schleiferi with the same biochemical properties from all animals. The multiresistance of the isolated cultures of Staphylococcus schleiferi to the same antibiotics was established using the disk-diffusion method. The antibiotics to which the studied microorganism is sensitive were determined. These include cephalosporins, amoxicillin with co-amoxiclav, ampicillin/sulbactam, linezolid, streptomycin, and furadonin. The obtained data are consistent with the studies of other authors studying the sensitivity to antibiotics of coagulase-negative staphylococci causing dermatitis in dogs, indicating the main selective role of antibiotics in the pathogenesis of dermatitis and otitis in dogs caused by Staphylococcus schleiferi, prescribed by veterinarians without microbiological determination of the sensitivity of cultures to antibiotics. Therefore, when dermatitis and otitis occur in dogs, it is necessary to analyze the sensitivity of isolated cultures to antibiotics and prevent the chronic form of the inflammatory process.
