Campylobacter were detected by PCR in feces of monkeys of different species (clinically healthy, with diarrhea, and dead from acute enteric infections). High prevalence of these bacteria in monkeys was revealed. The incidence of C. jejuni DNA in monkeys with acute enteric infections was higher than in healthy animals (69.6 and 51.3%, respectively). The highest percentage (92.3) of positive results was observed in Macaca mulatta with enteric diseases and in macaque dead of these diseases. The presence of C. jejuni in monkeys with diarrhea and the absence of pathogenic enterobacteria (Shigella, Salmonella, Yersinia) in feces probably attest to etiological relationship of acute enteric infections with Campylobacter.
Carriership of agents of sexually transmitted diseases (Trichomonas, Chlamydia, Mycoplasma, Ureaplasma) is highly prevalent in healthy monkeys living in the Adler Breeding Center. The incidence of these microorganisms is appreciably higher in animals with gestoses and labor abnormalities in comparison with animals with normal genital function. Mixed infection caused by 2-4 agents is much more incident than monoinfection.
Staphylococcus aureus (S. aureus) is a microorganism that causes a great number of diseases in humans and animals, including sepsis, pneumonia, food toxicoinfections, wound abscess, etc. Numerous studies on genotyping S. aureus strains isolated from humans, food and mastitis in cattle and small ruminants have been carried out. The lack of information on the genotyping of methicillin-susceptible S. aureus detected in monkeys served as a stimulus to conduct a similar research, since staphylococcal infections in the primates are widespread. The present study is devoted to molecular genetic testing of S. aureus isolated from different biological samples taken from monkeys and is based on typing of agr polymorphic locus which acts as a regulator of pathogenic gene expression. As a result of PCR analysis of 301 S. aureus isolates it was established that most of S. aureus belonged to agr IV (55%), and agr I (34%) was the second most group. Data resulting from the study differ from the results of other researchers published in literary sources, who performed typing of salmonella isolated from people with agr I prevailing. In conducting the study, neither distinct correlation between microbial isolation source and agr complex groups, nor relationship between the diseases and S. aureus group specificity were detected. Prevalence ratio of each agr group is nearly similar in S. aureus isolated from rhesus macaques and crab-eating macaques. But in hamadryas baboons and green monkeys II and III groups of agr complex were not detected.
Screening of monkeys for anaerobic bacteria showed that the incidence of non-spore-forming anaerobes was 2.0-2.5 times higher than that of clostridia. The overwhelming majority of isolated anaerobes were saprophytes and opportunistic bacteria. The incidence of C. perfringens was higher in monkeys with enteric infections of obscure etiology and dead from these diseases than in healthy animals (48.2 vs. 36.8%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
