The purpose of research is increasing the resistance of Guinea pigs to the action of pathogenic and conditionally-pathogenic microorganisms causing gastroenteritis. Based on the objectives of the problems were pointed– isolation and identification of guinea pigs transient and resident representatives microbiocenosis; study of morphological, tinctorial, cultural, biochemical and serological properties of these microorganisms. In the study, samples of facals and chimus of guinea pigs with the pathology of the gastrointestinal tract (gastroenteritis) have been isolated and identified resident microorganisms: Enterococcus faecalis – KOE 3.08h103±0.06, Peptostreptococcus anaerobius – 4.14h104±0.17, Lactobacillus delbrueckii – 4.36h103±0.04, Bifidobacte-rium bifidum – 3.85h103±0.06, Escherichia coli – 3.27h104±0.05, Serratia marcescens – 3.78h104±0.04, Bac-teroides fragilis – 3.88h105±0.14. Among the transient microorganisms were isolated Staphylo-coccus saprophiticus, Streptococcus entericus, S. gallolyticus, Enterobacter cloacae, Citrobacter diversus, Salmonella enteritidis, Yersinia enterocolitica, Bacillus subtillis, B. cereus, B. mycoides, B. lichieni-formis, Clostridium sporogenes, C. haemolyticum, C. histolyticum, Helicobacter pylori and Campylobacter coli. In conclusion: the main etiological factor for gastroenteritis tested guinea pigs are bacilli and clostridia, which in association with salmonella, jersiniya, helicobacter and campylobacter lead to growing intoxication and bacteriamia of animals. Against this background, the reduction in the concentration of resident microbial cultures that occupy an ecological area in the gastrointestinal tract. |
