Implications of Mycoplasma hemofelis Bacterial Load on the Hematological Parameters of Naturally Infected Cats.

Mycoplasma hemofelis is the most pathogenic hemoplasma species that affect cats. M. hemofelis may cause an acute infection that leads to hemolytic anaemia.

Genetic Diversity of the Cryptococcus gattii Species Complex in Mato Grosso State, Brazil.

Cryptococcosis is caused by fungi of the genus Cryptococcus. Owing to its importance, this study aimed to analyze the genetic diversity of C. gattii isolates from animals, humans, and the environment in Mato Grosso State (MT), Brazil, during November 2010-December 2017.

Hemostatic assessment of dogs associated with hepatic parasite load of Leishmania infantum chagasi.

Leishmania infantum chagasi liver parasite load was compared to hemostatic abnormalities, as well as to clinical, laboratorial, and histopathological findings in dogs with visceral leishmaniasis. The liver parasite load of 30 dogs L. infantum chagasi naturally-infected was evaluated by quantitative real- time PCR and the results were compared with serum biochemistry and primary and secondary hemostasis findings.

SAINT LOUIS ENCEPHALITIS VIRUS IN MATO GROSSO, CENTRAL-WESTERN BRAZIL.

The dengue virus (DENV), which is frequently involved in large epidemics, and the yellow fever virus (YFV), which is responsible for sporadic sylvatic outbreaks, are considered the most important flaviviruses circulating in Brazil. Because of that, laboratorial diagnosis of acute undifferentiated febrile illness during epidemic periods is frequently directed towards these viruses, which may eventually hinder the detection of other circulating flaviviruses, including the Saint Louis encephalitis virus (SLEV), which is widely dispersed across the Americas. The aim of this study was to conduct a molecular investigation of 11 flaviviruses using 604 serum samples obtained from patients during a large dengue fever outbreak in the state of Mato Grosso (MT) between 2011 and 2012.

Identification of genes expressed by Cryptococcus gattii during iron deprivation.

Cryptococcus neoformans and C. gattii are pathogenic yeasts that cause life-threatening diseases in humans and animals. Iron is an essential nutrient for virtually every organism as it functions as a cofactor in numerous essential enzymatic reactions.

Molecular typing and in vitro antifungal susceptibility of Cryptococcus spp from patients in Midwest Brazil.

Introduction: Cryptococcosis is a systemic fungal infection that affects humans and animals, mainly due to Cryptococcus neoformans and Cryptococcus gattii. Following the epidemic of acquired immunodeficiency syndrome (AIDS), fungal infections by C. neoformans have become more common among immunocompromised patients.

Cryptococcus gattii VGII in a Plathymenia reticulata hollow in Cuiabá, Mato Grosso, Brazil.

Little is known about the ecology of agents of cryptococcosis in Mato Grosso, without any data regarding to the sources of both agents in the environment. This study aimed to investigate Cryptococcus gattii and Cryptococcus neoformans associated with decay in tree hollows within the urban area of three different cities of Mato Grosso. Seventy-two environmental samples collected from 72 living trees in the cities of Cuiabá, Várzea Grande and Chapada dos Guimarães were sampled and analysed.

First report on Cryptococcus neoformans in pigeon excreta from public and residential locations in the metropolitan area of Cuiabá, State of Mato Grosso, Brazil.

Cryptococcosis is a severe systemic mycosis caused by two species of Cryptococcus that affect humans and animals: C. neoformans and C. gattii.

In vitro susceptibility of Conidiobolus lamprauges recovered from sheep to antifungal agents.

Data regarding the susceptibility of Conidiobolus lamprauges is limited and there is no consensus about the optimal treatment for infections caused by Conidiobolus spp. In this context, the objective of this study was to evaluate the in vitro susceptibility of six C. lamprauges strains isolated from sheep conidiobolomycosis to amphotericin B, ketoconazole, fluconazole, itraconazole, posaconazole, voriconazole, anidulafungin, caspofungin, micafungin, flucytosine, and terbinafine using the CLSI M38-A2 microdilution technique.

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).

Molecular characterization of ovine zygomycosis in central western Brazil.

Zygomycosis is an important granulomatous disease that affects humans and animals, particularly sheep in tropical regions. Rhinofacial and nasopharyngeal zygomycosis were described in sheep in association with Conidiobolus spp. The present study characterized 5 samples of Conidiobolus isolated from 3 herds with clinical disease in Mato Grosso State, Brazil.
