Prevalence of the pathatus Cryptosporidium parvum in syananthropic biocenoses

The purpose of the research is to determine relationship between infestation Cryptosporidium parvum in calves that have regular contact with synanthropic reservoirs (rodents and birds) climatic zones Udmurtia. study distribution manifestations cryptosporidiosis was carried out among rodents (gray rat (Rattus norvegicus), house mouse (Mus musculus), common vole (Microtus arvalis), bank (Myodes glareolus)) birds (rock dove). (Columba livia), sparrow (Passer domesticus), jackdaw (Coloeus monedula)). In total, 255 calves, 160 80 were subjected study.The assessment by generally accepted coprological flotation methods, as well making native smears further Ziehl-Neelsen staining. results obtained evaluated using statistical methods: analysis variance, taking into account Fisher criterion Pearson correlation coefficient.The showed all natural Udmurt Republic a high percentage infection recorded.On territory southern zone, rate 62.35%, while captured mouselike prevalence invasion at level 37.25%, - 20.0%.In farms located on northern zone republic, degree reached 41.18%, 23.91%. minimum detection cryptosporidium oocysts observed north Udmurtia 11.77%.The fact dependence causative agent presence parasite carriers has been established. According calculating coefficient direct close revealed representatives reservoir rodents, birds, regularly agricultural crops. animals.
