The Pantanal region, the largest floodplain in the world, has a huge biodiversity and is an important livestock center. Bovine brucellosis has been reported in the region over the last three decades, posing implications for cattle industry as well as for the maintenance of biodiversity. We aimed to investigate the presence of B.

Methods: Artiodactyl feces were collected between 2020 and 2021. The fecal samples were examined to identify the host through macroscopic and molecular analysis.
In captivity, snakes may present chronic infections with high mortality, such as those caused by Cryptosporidium serpentis, or they may be pseudoparasitized by species that present zoonotic potential. Thus, the aim of this study was to evaluate the frequency of helminths and protozoa in the feces of captive snakes, characterize the species and subtypes of Cryptosporidium spp. and correlate the parasites detected with other information obtained from these animals.

The law 13,123 / 2015 determined a significant change in the theme, mainly on the rules of distribution of benefits obtained for conservation and sustainable use of biodiversity, the access to technology and technology transfer, the exploitation of products or reproductive material from the GR or ATK and consignment to the outside of part or all the living or dead organism shipped for GR. The implementation of international treaties on GR and ATK for research, biotechnological development and bioprospecting have been causing difficulties for Brazilian researchers, mainly due to the lack of information and dissemination available for compliance with the legislation.

In South America, visceral leishmaniasis is a zoonotic disease with severe evolution characteristics in humans, and dogs are its main reservoir. In this context, this study aimed to evaluate the clinical status of dogs from a Brazilian endemic area naturally, at Barra Mansa municipality, infected with Leishmania infantum, in conjunction with their histopathological profile and, in order to determine possible markers of susceptibility or resistance to the disease, parasitic DNA load, cytokine and iNOS mRNA expression profiles were investigated in lymph nodes. High levels of IFN-ɣ and IL-6 mRNA were detected.
