Parasitocenoses in cattle and their circulation in small farms

Abstract

Research on the study of parasitocenoses in endometritis and mastitis in cows, as well as gastrointestinal and respiratory diseases of newborn calves, were carried out in 12 farms in the Moscow region with a total number of 4,445 cows and 12,254 cattle. It was found that parasitocenosis in cattle in the farms of Moscow region are vulnerable to factor of infections composed of S. agalactiae, S. dysgalactiae, S. uberis, S. pyogenes, S. pneumoniae, S. faecalis, S. aureus, S. albus, S. saprophyticus, S. epidermidis, S. intermedius, S. enterica (S. enteritidis, S. typhimurium, S. dublin), E. coli (O1, O2, O4, O8, O9, O18, O22, O26, O33, O78, O101, O111, O126, O137), P. aeruginosa, P. multocida, K. pneumoniae, K. oxytoca, P. vulgaris, P. mirabilis, B. subtilis, B. cereus, C. freundii, L. plantarum, L. rhamnosus, L. acidophilus, L. xylosus, L. lactis and C. albicans. This research found that mastitis and endometritis in cows, as well as gastrointestinal and respiratory diseases in newborn calves, are caused by almost similar associations of microorganisms (parasitocenoses) that circulate in the farm (intra-farm infection). The results of the experiment indicate that the association of conditionally pathogenic microorganisms that circulate among cattle of farms in the Moscow region are parasitocenoses, and are independently regulated under the influence of macroorganism and environmental factors; it is a complex, multicomponent, strictly balanced ecosystem, each of which is an important link in the etiological factor of cattle infections.
