Literature primarily associates the transmission of Leptospira interrogans with contact with the urine and carcasses of rodents, particularly Rattus norvegicus and Rattus rattus. However, it is understood that inter and intraspecific transmission occurs in other hosts, including domestic species such as Canis familiaris. Given the strengthening bond between humans and companion animals, coupled with urbanization and disparities in public health policies, a shift in the epidemiological profile of the disease has been observed. The objective of this research was to establish a correlation between the occurrence of leptospirosis in dogs and the determining factors of the disease in the city of Uberlândia-MG. A descriptive analysis of the characteristics of seroreactive dogs was performed, along with an evaluation of the efficacy of municipal rodent control and the application of a binomial test for two proportions between reactive animals during the rainy and dry seasons. The results demonstrated a change in the serological profile of the canine population, with the majority of positive animals being mixed-breed and non-neutered. The rodent control program promoted a reduction in the infestation index of manholes in the analyzed neighborhoods. Furthermore, no statistically significant difference was observed in the occurrence of cases between the dry and rainy periods, although the influence of potential biases in laboratory test requests on these results is discussed.

In this context, the present study investigated the effects of genetic alterations and age on the reproductive function of knockout mice. For this purpose, males of the C57BL/6 (wild type), Galectin-3-/-, Interferon Gamma (IFN-γ-/-) and Toll-Like Receptor 3 (TLR-3-/-) strains were used at two different ages, 8 and 12 weeks. After euthanasia, body and reproductive organ weights were assessed, and sperm were collected for analysis of vitality, motility, and morphology. No significant differences in body or reproductive organ weights were observed between the groups. However, sperm analysis showed that TLR-3-/-, animals had a higher incidence of midpiece insertion defects. The GAL-3-/- group, on the other hand, had a higher incidence of tail defects. In contrast, the IFN-γ-/- lineage did not show detectable abnormalities in any of the sperm parameters analyzed. Based on the results found, it can be concluded that the absence of TLR-3 and Galectin-3 has a distinct and negative impact on sperm quality. On the other hand, the absence of changes in the IFN-γ-/- group suggests a modulatory role for this gene, where its absence may be associated with functional stability. These findings reinforce the selective influence of immune genes on reproduction and point to potential therapeutic applications in the treatment of reproductive problems, requiring further studies with this focus.

Commonly associated with latent and recurrent infections, herpesviruses are highly host-specific, linked to their hosts through coevolution, and, in rarer cases, can be transmitted between individuals of distinct species through spillover events, enabling potential zoonotic transmission. In this study, a total of 92 tissue samples (spleen and lung) were collected from animals hunted in Indigenous communities in the state of Mato Grosso or roadkilled in the state of Pará. Sampled species included the red howler monkey (Alouatta guariba), collared peccary (Dicotyles tajacu), gray short-tailed opossum (Monodelphis brevicaudata), crab-eating fox (Cerdocyon thous), mouse opossum (Marmosa demerarae), gracile mouse opossum (Gracilinanus microtarsus), red-rumped agouti (Dasyprocta leporina), black bearded saki (Chiropotes satanas), common opossum (Didelphis marsupialis), ocelot (Leopardus pardalis), Guiana capuchin (Sapajus apella), wild marsupials (Monodelphis spp.), Brazilian porcupine (Coendou prehensilis), lowland paca (Cuniculus paca), brown-throated sloth (Bradypus tridactylus), Linnaeus’s two-toed sloth (Choloepus didactylus), South American coati (Nasua nasua), white-lipped peccary (Tayassu pecari), wild rodents (Akodon spp., Cavia spp., and Proechimys spp.), southern tamandua (Tamandua tetradactyla), Brazilian rabbit (Sylvilagus brasiliensis), and red brocket deer (Mazama americana). Herpesvirus detection was performed by Nested PCR targeting the herpesvirus DNA polymerase gene. Overall, 43.47% (40/92) of the samples tested positive, with 8.69% (8/92) from white-lipped peccaries, 6.52% (6/92) from brazilian porcupines, 6.52% (6/92) from pacas, 5.43% (5/92) from red howler monkeys, 3.26% (3/92) from Guiana capuchins, 2.17% (2/92) from southern tamanduas, 2.17% (2/92) from red brocket deer, and 1.08% (1/92) each from collared peccary, crab-eating fox, mouse opossum, black bearded saki, common opossum, ocelot, wild rodents, and Brazilian rabbit. These results represent the first detection of herpesviruses in collared peccaries, mouse opossums, black bearded sakis, Brazilian porcupines, pacas, southern tamanduas, and red brocket deer.
