“…However, de Oliveira et al [ 42 ], described the uterus as being partially double, comprising of two horns and a septate cervix (two internal cervical ostia), in which the septum disappeared caudally to create a single ostium (external cervical ostium) that opened into the vagina. On the other hand, Martins et al [ 44 ] stated that, despite there being only one external cervical ostium, it was characterized as a double uterus.…”

This is the second of two literature reviews that focuses on the female reproductive anatomy and reproductive technologies used in selected neo-tropical hystricomorphic rodents. The rodents chosen included the agouti (Dasyprocta leporina), the capybara (Hydrochoerus hydrochaeris), and the paca (Cuniculus paca). Over seventy references were used, spanning the years 1919–2021. Knowledge of the reproductive tract is important in understanding any unique features, which may affect the use of reproductive technologies. Some unique characteristics common to these species included the presence of a vaginal closure membrane and a lobulated placenta with a vascular sub-placenta. The capybara had hyperpigmentation of the vagina that was unique to each individual, while the agouti and paca had accessory corpora lutea, in addition to the main one. Some reproductive technologies have been used, with attempts at estrous induction and synchronization taking place within the past five years. Even though most work has been done over the past twenty years, there is still a dearth of information.

“…A cutia constitui uma espécie com crescente interesse científico, fato que pode ser observado em diversos artigos recentes sobre determinação da taxa metabólica basal (BRITO et al, 2010), anatomia dos esqueletos axial (OLIVEIRA et al, 2009a) e do apendicular (OLIVEIRA et al, 2009b), além de anestesia (MARTINS et al, 2011a), cirurgia (MARTINS et al, 2010), morfologia uterina (MARTINS et al, 2011b) e determinação da microbiota intestinal (OLIVEIRA et al, 2009c).…”

ResumoOs órgãos genitais dos animais domésticos geralmente são colonizados por diversos microrganismos. O objetivo deste trabalho é descrever a microbiota do útero e da vagina em cutias nulíparas e não nulíparas, pertencentes ao Zoológico Municipal de Catanduva -SP. Durante ovariossalpingohisterectomia, colheu-se material para a análise microbiológica mediante a introdução de swabs estéreis na vagina e em cada corno uterino. Observou-se presença de Proteus sp. no material uterino de apenas um dos animais. No material vaginal de todos os animais constatou-se a presença de várias bactérias (Proteus sp., Escherichia coli, Citrobacter sp., Pseudomonas sp. e Staphylococcus sp.) e leveduras. A microbiota vaginal e uterina de cutias apresenta padrão de colonização diferente daquela observada em outros animais domésticos, na mulher e na rata. Palavras-chave: Lagomorfo; Microbiota; Roedor; Trato reprodutivo AbstractMicrobiological analysis of the uterus and vagina of nulliparous and non-nulliparous agoutis (Dasyprocta azarae). The genital organs of domestic animals are usually colonized by several microorganisms. This paper aims at describing the uterine and vaginal microbiota of nulliparous and non-nulliparous agoutis, which belong to the Catanduva City Zoo, Sao Paulo, Brazil. During the procedure of ovariosalpingohisterectomy, material was collected for microbiological analysis through the introduction of sterile swabs in the vagina and in each uterine horn. The presence of Proteus sp. was observed in the uterine material of only one animal. In the vaginal material of all animals, several bacteriae (Proteus sp., Escherichia coli, Citrobacter sp., Pseudomonas sp., and Staphylococcus sp.) and yeasts were found. The vaginal and uterine microbiota of agoutis presents a colonization pattern different from that observed in other domestic animals, in women, and in female rats.

The study investigated the gross and microscopic anatomy of the genital organs of 20 agoutis at different stages of the estrous cycle and four in the final trimester of pregnancy. Specimens were euthanized and their reproductive organs were fixed in a 4% paraformaldehyde or 2.5% glutaraldehyde solution and submitted to routine histological techniques for light and scanning electron microscopy. In the ovary, during the proestrus phase, we observed developing follicles and corpus luteum (CL) in regression; during estrus, there were Graafian follicles; during metestrus, there was a hemorrhagic corpus, whereas in diestrus, there was a mature CL. The uterus was partially double because the cervix was cranially septate but caudally, the septum disappeared, forming a single ostium that opened into the vagina. Changes occurred along the estrous cycle in the uterine and vaginal epithelia, that is, an increase in the uterine epithelium height accompanied by an increase of thickness of the vaginal epithelium during the follicular phase and a decrease of thickness of both epithelia during the luteal phase. The endometrial lining was composed of a simple cuboidal epithelium to simple columnar epithelium with basal nuclei. The vaginal mucosa consisted of epithelium that varied from nonkeratinized stratified squamous (luteal phase) to keratinized stratified squamous (follicular phase). The clitoris was external to the vagina. It presented two protruding lateral keratinized spicules and a centralized urethra, with no common parts between the urinary and genital tracts. Anatomical and histological changes were observed mainly in the cervix, vagina and spicules of the clitoris during the EC.
