Although leptospirosis has been described in capybaras, usually based on serological evidences, bacterial culture of leptospires has been scarcely reported in this species. The western Amazon is a reportedly endemic area where high seroprevalences have been reported in different species of wildlife, domestic animals and in human beings. The present study aimed at investigating the role of capybaras as carriers of leptospires in periurban and rural areas in the western Amazon region. A total of 44 animals were captured, and 41 blood samples (for serology) and 41 urine samples (for PCR and bacterial culture) were obtained. A total of 18/41 (43.9%) of sera were reactive and titers were generally low, indicating chronic infection. PCR was positive in 13/41 (31.7%) samples, isolates were recovered from urine samples belonging to Icterohaemorrhagiae, Grippotyphosa and Shermani serogroups. A high number of carriers (confirmed by PCR) associated to a tendency for harboring Icterohaemorrhagiae serogroup strains could be noticed. Our results suggest that capybaras are massively infected by leptospires. Analogously to Norway rats, capybaras present chronic infection with low titers and long-term bacterial shedding, and may be acting as reservoirs of this bacterium.

The objective of this work was to describe in 27 pacas (Cuniculus paca Linnaeus, 1766) at 30, 60 and 90 days (D) of pregnancy diagnosed by ultrasonography (U.S.) the cell types of the vaginal epithelium by vaginal smears, to report the vulva opening condition and the characteristics of vaginal mucus, to determine the progesterone (P4) serum concentration by radioimmunoassay, and also measure by ultrasound (U.S.) the fetuses biparietal diameter (BPD) at 60 and 90 days of pregnancy. At D30, 40% of the smears exhibited surface cells (with estrogenic characteristics) and of naked nuclei. At D60 and D90, parabasal, intermediate, superficial, and navicular cells were present in the same proportions, but endocervical cells were described in only 73.9% and 69% of those days smears, respectively. At D30 the highest proportion of navicular and surface cells differed (p < 0.05) compared with other cell types. The vaginal mucus was crystalline and fluid in 100% and 70% of females at D30 and D60, respectively. It was observed the vaginal vestibule open in around 50% of females in every day of exams. Minimum detectable P4 serum concentration was obtained on 72% and 83% of females, while the averages of the BPD were 1.25 cm (± 0.16) and 2.34 cm (± 0.25) on D60 and D90, respectively. Vaginal cytology aspects at D30, D60 and D90 and BPD provide elements to contribute to pregnancy diagnosis in paca. P4 concentration shows the need of further endocrinology of pregnancy studies of paca.

The interaction between men and animals results in consequences for public health, such as the increase of rabies cases, a lethal zoonosis. In this study, a total of 1047 file cards from the Brazilian Notification Aggravation Information System (Sistema de Informação de Agravos de Notificação SINAN) were analyzed. The analyzed data was representative of human anti-rabies preventive treatment in the city of Cruzeiro do Sul, Acre, from 2007 to 2015. Most cases were registered in 2013 (17.95%). The highest incidence of attacks occurred in urban regions (86.1%). Wounds from dog bites corresponded to 98.66% of the attacks. The animals were classified as suspected rabies in 65.42% of cases. However, only 1% were clinically diagnosed as positive. Only 4% of the human victims were subjected to examination for post-exposure titration. The results indicate that Public Health programs should consider dog bite attacks in the urban area as a priority in in the city of Cruzeiro do Sul.

Estrus synchronization is a reproductive biotechnology used to improve artificial insemination or pairing through the manipulation of the estrous cycle at a desirable time. Employing this technique in captive pacas (Cuniculus paca L.) is important because it creates expectation of meeting the demand for paca meat and, consequently, reduces poaching. Thus, this research aims to verify the effect of a progestogen implant associated with two doses of eCG on the synchronization and induction of fertile estrus. Twenty-seven adult pacas were used, 18 non-pregnant females and nine males, divided into three groups. G1 and G2 females groups (treatments) received 1.5 mg Norgestomet and were injected intramuscularly, seven days later, with 0.13 mg of prostaglandin. After 24 hours the implants were removed and the animals immediately received 25 IU and 50 IU of ECG intramuscularly, respectively. The mating of the three groups took place on the same days. G3 females’ group (control) showed estrus on different days after D0. Females under treatment displayed estrus only after removing the implant (D8). G1, G2, and G3 pregnancy rates were 100%, 66%, and 50%, respectively. Regarding births per parturition, 100% of G1 and G3 produced one offspring, while 50% of G2 produced two. Progestogen in the form of subcutaneous implants was effective in mimicking the luteal phase of the estrous cycle. After removal, implants favored the occurrence of a fertile estrus. As a conclusion, further studies must be conducted in order to establish in-depth possible association between 50 IU of eCG, and the occurrence of twin pregnancies.
