Neospora caninum causes reproductive problems in cattle such as abortion, premature birth, retention of fetal membranes, and metritis. Therefore, this study aimed to verify possible risk factors for N. caninum infection in dairy cattle and their cause-effect relation to neosporosis. Serum samples of 1518 dairy cows from the West of Santa Catarina State, Southern Brazil were analyzed by indirect immunofluorescence assay (IFA) for N. caninum, where 466 were found to be positives (30.69%-CI95%; 28.3- ...

Toxoplasma gondii, an intracellular protozoan, may cause chronic infection in the brain tissue of the host inducing a systemic pro-inflammatory profile. Chronic infections can induce numerous physiological changes, such as alterations in the immune and oxidative profiles. Diphenyl diselenide (PhSe)2, an organoselenium compound, has shown antioxidant and immunomodulatory activities in recent studies. So, the aim of this study was to investigate the activity of purinergic enzymes and reactive oxygen ...

The aim of this study was to verify the effect of diphenyl diselenide (PhSe)2 on hepatic nucleotidases and on the concentration of purines in mice infected by Toxoplasma gondii. The animals were divided into four groups: Group A (uninfected), Group B (uninfected and treated with (PhSe)2), Group C (infected), and Group D (infected and treated with (PhSe)2). The inoculation (groups C and D) was performed with 50 cysts of T. gondii (ME-49 strain). Mice from groups B and D were treated with 5 μmol kg-1 of (PhSe) ...

A infestação por carrapatos em bovinos é responsável por perdas econômicas significativas à indústria animal em várias regiões brasileiras, incluindo o Rio Grande do Sul. As perdas se devem ao stress, a perdas de peso e a injúrias na pele, bem como aos custos com tratamentos. O uso indiscriminado de carrapaticidas tem contribuído para o aparecimento da resistência genética dos ixodídeos a várias drogas, representando um sério problema no controle de carrapatos.

Neospora caninum and Toxoplasma gondii are coccidian parasites (protozoa: Apicomplexa) that cause reproductive losses in ruminants. Although, in sheep, abortion is generally related to T. gondii, potential damage caused by N. caninum must be considered. The aims of this study were to evaluate the frequencies of antibodies against Neospora spp. and T. gondii, and to identify the risk factors related to neosporosis and toxoplasmosis in sheep from ten flocks located in Central-Western, Northwestern, ...

Toxoplasma gondii is a protozoan that has great genetic diversity and is prevalent worldwide. In 2018, an outbreak of toxoplasmosis occurred in Santa Maria, Brazil, which was considered the largest outbreak ever described in the world. This paper describes the isolation and molecular characterization of Toxoplasma gondii from the placenta of two pregnant women with acute toxoplasmosis who had live births and were receiving treatment for toxoplasmosis during the outbreak. For this, placental tissue ...

The protozoan Toxoplasma gondii is a causative agent of toxoplasmosis, an important and widespread zoonotic disease. The transmission of this disease in humans includes ingestion of sporulated oocysts present in contaminated water or food. T. gondii oocysts are widely distributed and toxoplasmosis is considered a major food- and waterborne pathogen worldwide, making drinking water containing sporulated T. gondii oocysts a major source of contamination for people.
