Qualitative analysis of preputial and vaginal bacterial microbiota in owl monkeys (Aotus azarai infulatus) raised in captivity.

BACKGROUND: The aim of this study was to identify the aerobic bacteria of the preputial and vaginal microbiota in owl monkeys that have been raised in captivity and to evaluate the antimicrobial susceptibility of these bacteria by gender and social organization. METHODS: Thirty clinically healthy Aotus azarai infulatus were used. A total of 134 samples were collected, 60 from the preputial mucosa and 74 from the vaginal mucosa. An automated system of bacterial identification was used. RESULTS AND CONCLUSIONS: Staphylococcus intermedius and Proteus mirabilis were the microorganisms that were most frequently identified according to gender and social organization. The antimicrobial susceptibility of the isolated gram-positive bacteria was similar in both sexes. However, the gram-negative strains had some differences. The aerobic bacterial population of the vaginal and preputial microbiota is similar in owl monkeys, and there are no differences in the number and bacterial species according to sex and social organization.

Effect of age and number of parturitions on uterine and ovarian variables in owl monkeys.

BACKGROUND: We aimed to evaluate the uterine and ovarian volumes of owl monkeys in different age groups with different numbers of live births and to analyze the interaction between both. METHODS: We performed pelvic ultrasound exams to compare the uterine measurements with weight, age (infant, juvenile, subadult, young adults, and adults) and the number of live births (nulliparous, primiparous, and multiparous) and to compare the ovarian measurements with weight and age. RESULTS AND CONCLUSIONS: The uterine volume (UV) was directly proportional to the number of parturitions, which was the most important factor in the uterine growth of adult females (P < 0.05). The body weight and age of the animals showed a high positive correlation with UV (r = 0.5354, r = 0.6489, P < 0.01), respectively. The volume of the ovaries grew in proportion to the age of the females (P < 0.05). Puberty was the period of greatest uterine and ovarian growth.

Hematological, hepatic, and renal evaluation in Aotus azarai infulatus.

BACKGROUND: Knowing the physiological ranges of certain hematological and biochemical parameters is necessary for understanding the alterations caused by pathogenic agents and establishing differences between states of health and disease. Hematological evaluations and clinical chemistry were performed on livers and kidneys from owl monkeys with different sexes and age ranges. METHODS: Forty-one healthy owl monkeys were evaluated (26 males and 15 females) in three different age groups (AG1=3months to 1 year old; AG2=2-6years old; AG3=over 7years old). The animals received physical exams, abdominal ultrasounds, and clinical laboratory tests. RESULTS AND CONCLUSIONS: Significant differences were observed in hematocrit and hemoglobin values between males and females. The levels of alkaline phosphatase in the tissues were significantly influenced by age. There was also a sex influence on blood urea nitrogen and creatinine levels. The results show that some hematological and clinical chemistry parameters in owl monkeys may be influenced by sex and age.
