Ehrlichia sp. in dairy cattle from Bahia, Brazil: high seropositivity rates and molecular confirmation of Ehrlichia minasensis.

Background: Ehrlichia spp. are obligate intracytoplasmic Gram-negative tickborne bacteria from the Anaplasmataceae family. Ehrlichiosis is considered an emerging disease in humans and animals.

sp. shed by the common boa snake () in Brazil.

The genus contains around 200 species and 25 of these infect snakes. Two spp. shed by snakes have called special attention of the scientific community.

Cryopreservation of jaguar () sperm cells using different cryoprotectants and different thawing temperatures.

The cryopreservation of jaguar semen must be improved to produce high-quality biobanking doses. Until now, the rare studies of semen freezing in the species have only evaluated glycerol, always with a significant reduction in sperm quality in thawed semen. The purpose of this study was to assess the efficacy of three cryoprotectants, dimethylsulfoxide (DMSO), glycerol (GLY), and methanol (MET), in the cryopreservation of jaguar semen in an LDL-based extender, as well as the effect of thawing temperature on dosage quality.

Translation, cross-cultural adaptation, and validation of the Behavioral Activity Rating Scale (BARS) for the Brazilian population.

Introduction: Few instruments are available in Brazil to evaluate psychomotor activity in psychiatric emergency, clinical, and research settings. This study aimed to perform a cross-cultural adaptation of the Behavioral Activity Rating Scale (BARS) into Brazilian Portuguese and assess the adapted scale's psychometric properties.

Method: An expert consensus committee conducted a translation and back-translation of the original scale, resulting in the BARS-BR.

Reactivity of Horse Sera to Antigens Derived From -Like and .

and are protozoan parasites endemic to the Americas. The former is the major cause of equine protozoal myeloencephalitis, and the latter is associated with pulmonary sarcocystosis in birds. The opossum is the definitive host of these parasites in North America.

Serologic cross-reactivity between Sarcocystis neurona and Sarcocystis falcatula-like in experimentally infected Mongolian gerbils.

Sarcocystis neurona is the major cause of the equine protozoal myeloencephalitis (EPM) in the Americas and has opossums of the genus Didelphis as definitive hosts. Most isolates of Sarcocystis sp. shed by opossums in Brazil differ genetically from the known species of Sarcocystis.

-like derived from opossum in Northeastern Brazil: propagation in avian cells, molecular characterization and bioassay in birds.

Most reported isolates of spp. derived from Brazilian opossums ( sp.) have genetic characteristics distinct from the known species of , but behave similarly as , as they are infective to budgerigars.

Toxoplasmatinae Parasites in Bats from Bahia State, Brazil.

Toxoplasma gondii and Neospora caninum are widespread cyst-forming coccidian parasites of the subfamily Toxoplasmatinae that infect a wide range of wild and domestic animals. Whereas T. gondii is a zoonotic disease, N.

Sarcocystis spp. in sheep and goats: frequency of infection and species identification by morphological, ultrastructural, and molecular tests in Bahia, Brazil.

Sarcocystis spp. are cyst-forming coccidia that infect numerous animals species, including several livestock species. Despite the importance of sheep and goat production in Brazil, little it is known about the Sarcocystis species that infect small ruminants in the country and their potential impact on meat condemnation due to the presence of macroscopic cysts of the parasite.

Diagnostic performance of anti-beta2 glycoprotein I and anticardiolipin assays for clinical manifestations of the antiphospholipid syndrome.

The objective of the present study was to analyse the performance of the tests for detection of anti-beta2 glycoprotein I (beta2 GP I) and anticardiolipin (aCL) antibodies for identification of clinical manifestations of the antiphospholipid syndrome (APS). Patients with systemic lupus erythematosus (SLE) as well as carriers of infectious diseases such as Kala-azar, syphilis and leptospirosis were studied. Particular interest was given to the presence of clinical complications related to APS.

[Frequency and implications of autoantibodies in acute viral hepatitis].

There are interactions between hepatotropic viruses and the host immune system, which could contribute to liver damage in viral hepatitis. The aim of this study was to investigate the frequency of autoantibodies in patients with acute viral hepatitis and their relationship with biochemical activity, severity of acute illness and chronicity rate. From 1992 to 2000, 156 patients with acute viral hepatitis were enrolled in a prospective study.
