Genotyping of rabies positive samples isolated from animals in Mato Grosso and Rondônia - Brazil.

Lyssavirus is a genus that causes infectious disease transmit by bats transmit, which results in economic losses in livestock and public health problems. From 2005 to 2019, more than 49 thousand cases of the disease were registered in animals in Brazil, with 3418 registered in Mato Grosso (MT). The lack of information on the genetic diversity and distribution of the rabies virus in MT was the motivation for carrying out this study.

Use of parasitological culture to detect Leishmania (Leishmania) chagasi in naturally infected dogs.

In Brazil, although the domestic dog is a major target for the control actions for visceral leishmaniasis, knowledge gaps of the Leishmania species present in those animals still exist in many endemic areas. The objective of this study was the use of parasitological culture as a diagnosis tool and identification of species of Leishmania and other trypanosomatids in the canine population in the city of Cuiaba/Mato Grosso. Biological samples such as blood, intact skin fragments, cutaneous ulcers, and bone marrow were collected during a cross-sectional study and cultured on biphasic medium (Novy-MacNeil-Nicolle [NNN]/Schneider's).

Granulomatous meningoencephalitis due to toxoplasma gondii in a black-headed night monkey (Aotus nigriceps).

This report describes toxoplasmosis infection in a black-headed night monkey (Aotus nigriceps) from the Zoological Park of the Federal University of Mato Grosso, Brazil. The animal was submitted alive to the Veterinary Hospital of the Federal University of Mato Grosso presenting neurologic clinical signs. There were no improvements on the animal's clinical condition after treatment, so it was euthanized.

[Seroepidemiological survey of canine leishmaniasis in endemic areas of Cuiabá, State of Mato Grosso].

Leishmaniases are zoonoses that are undergoing expansion in Brazil. Dogs are of importance regarding transmission and dispersion of the disease, especially in areas presenting visceral leishmaniasis. The aim of this study was to evaluate the seroprevalence of leishmaniasis among domestic dogs in the urban area of Cuiabá.
