Microbial landscape in acute purulent-catarrhal postpartum endometritis in cows

Abstract

A special place among environmental factors affecting the body of animals is occupied by microorganisms— pathogens of infectious diseases. In this regard, the problem of circulation of associations of conditionally pathogenic microorganisms capable of causing a fairly wide range of pathologies in cattle in cattle is acute. The article provides a study of the microbial background of the vaginal-luminous contents selected in the acute purulent-catarrhal postpartum endomethry in cows. It was shown that 58 strains of opportunistic microorganisms of 13 species, classified into 6 genera, were isolated from 20 cows suffering from acute purulent catarrhal endometritis. The most frequently isolated cultures were St. aureus, E. coli (serotypes O4, O9 and O83), Str. pyogenes, Str. agalactiae, P. aeruginosa, Str. uberis and Str. faecalis. Moreover, the development of acute purulent-catarrhal endometritis in cows was more often caused by grampositive bacteria. Of the 58 isolated strains of microorganisms, 22 (37.9%) cultures caused the death of white mice when administered intraperitoneally. At the same time, gram-positive cocci were more likely to have pathogenic properties, namely representatives of the genera Streptococcus spp. (11 — 50.0%) and Staphylococcus spp. (6 — 27.3%) isolates, respectively. It was found that endometritis more often causes associations of opportunistic microorganisms, which included three joints in 14 (50.0%) cases, less often four joints in 7 (25.0%) cases. The isolated microorganisms were sensitive to only three antibacterial drugs: cefkin, cefepime and marbofloxacin.
