Background: In the Americas, visceral leishmaniasis (VL) results from the zoonotic transmission of Leishmania infantum. VL has a high occurrence rate in the Metropolitan Region of Belo Horizonte (BH), Minas Gerais, Brazil, and has rapidly spread throughout the municipality since it was first recorded in 1994. This research analysed a historical perspective over 25 y of human VL occurrence in BH.

Blastocystis is a protist that infects both human and animal hosts worldwide. This study aimed to investigate the presence of Blastocystis in humans and domestic animals living in a periurban (PZ) and rural zone (RZ) in Northeastern Argentina and to assess their relation to socio-environmental conditions and hygiene practices as risk factors for human infection. In addition, we identified Blastocystis subtypes to evaluate the risk of zoonotic transmission.

Forest edges, where humans, mosquitoes, and wildlife interact, may serve as a nexus for zoonotic arbovirus exchange. Although often treated as uniform interfaces, the landscape context of edge habitats can greatly impact ecological interactions. Here, we investigated how the landscape context of forest edges shapes mosquito community structure in an Amazon rainforest reserve near the city of Manaus, Brazil, using hand-nets to sample mosquitoes at three distinct forest edge types.

Ardeids are wild birds well adapted to urban and periurban environments. However, the association of wildlife with humans and livestock increases the chances of transmission of microorganisms between wild animals, domestic animals and humans. The present study aimed to investigate the occurrence of Salmonella spp.

Domestic animals can share viral pathogens with humans, acting mainly as a bridge host. The genus hosts important zoonotic species that have emerged in urban areas worldwide. Nevertheless, the role of companion animals, such as dogs and cats, in the circulation of orthopoxviruses in urban areas remains poorly understood.
