Abstract. Modern intensive livestock management leads to polymorphic symptoms of associated infections. Microorganisms such as enterococcus and yeast-like fungi of the genus Candida spp. aggravate the course of the infectious process. Accurate diagnosis is only possible with the determination of a wide range of microorganisms, to avoid false-positive or false-negative results. Studies aimed to determine the pathomorphological changes in internal organs in rabbits with associated bacterial infections diagnosed using a wide range of selective media. Pathomorphological and bacteriological studies were carried out on 15 rabbit corpses from two farms in the Kemerovo region. The death of 9 animals occurred after weaning from the doe-rabbit at the age of 15-20 days, 6 animals died at the age of 60 days. The death of animals occurred sporadically without reference to a specific place or season. In bacteriological analysis, the widest range of nutrient media was used: for the cultivation of enterobacteria, staphylococci, enterococci, microscopic yeast-like fungi, the significance of which in infectious pathology is confirmed by the literature data. Associated opportunistic infections cause dystrophic changes in the liver and kidneys, pneumonia and meningoencephalitis, gastroenteritis, flatulence, fibrinous peritonitis. In each clinical case, yeast of the Candida spp. family was present in all internal organs, the proportion of which was 23%. Microorganisms of the Enterococcus spp. accounted for 22%, Staphylococcus spp. – 17%, which indicates their importance in the infectious process in rabbits. All animal deaths were associated with polymicrobial infection. There is a need to use selective media for the cultivation of these families of microorganisms in diagnostic manoeuvres.
