Assessment of antibiotics sensitivity of the most frequent potential pathogen bacteria isolated in the microbiology laboratory of the Faculty of Veterinary Medicine Iași, during 2017-2018

Abstract

In the veterinary practice, establishing the etiological diagnosis represents the quintessence of the anti- infectious therapy. The final diagnosis based on the correctness of the laboratory results and the microbiological examination, together with the hematological, immunological, histopathological, etc., has a major role in getting the right therapeutic protocol. In the current context, characterized by a wide etiological variety of infections, it is necessary to identify and test the sensitivity to antibiotics of pathogens isolated from different biological samples. The present study of the Microbiology Laboratory of the Faculty of Veterinary Medicine Iași presents the results obtained on various strains isolated from dogs and cats with different diseases during 2017-2018. The tests performed on of 83 microbiological samples (otic, pharyngeal, cutaneous and conjunctival secretions, urine, feces, etc.) identified 107 aerobic and anaerobic bacterial strains, classified into 20 bacterial genera. The most commonly isolated aerobic bacterial species were: Staphylococcus pseudointermedius (27.10%), Streptococcus sp.gr.G (8.41), Enterococcus faecalis (4.67%), Streptococcus sp. gr.C (3.73%), Pseudomonas aeruginosa (5.60%), Klebsiella pneumoniae (2.80%). The most commonly isolated anaerobic bacterial species were: Clostridium perfringens (9.35%), Campylobacter sp. (1.87%).The results of the antibiograms revealed a wide variability of sensitivity and resistance of the isolated strains to the antibiotics, most of them being multiple drug resistance.
