Dinâmica ovariana e microbiota vaginal durante o ciclo estral em cutias Dasyprocta prymnolopha Wagler, 1821 criadas em cativeiro.

Abstract

Abdominal ultrasonography was used to characterize the morphological changes occurring in the ovaries of the cutias of the species Dasyprocta prymnolopha raised in captivity, besides identifying the intravaginal microbiology existing in the same species for each phase of their respective strains cycles. All animals were submitted to daily vaginal cytology to identify the phases of the estrous cycle. For each phase, ultrasound examinations were performed to identify and describe the morphology of both ovaries, establishing topographic parameters in an ultrasound window to locate them, as well as the microbiological culture of vaginal contents in order to identify the colonies in the vaginal microbiota for each stage of the estrous cycle. The mean duration of the estrous cycle in the animals studied was 29.94 ± 6.7 days. In the analysis of ovarian morphology, no significant morphometric changes were observed in the measurements performed, however the presence of follicles was observed in 75% of the proestrus phases. It was observed a great diversity of bacteria existing in the vaginal microbiota of the agouti, predominating bacteria of the genera such as: Streptococcus sp., Bacillus sp., Escherichia coli, Citrobacter amalonattus, Staphylococcus sp., Corynebacterium sp., Klabsiella sp., Proteus sp., Ttrueperella sp., Enterobacter spp.
