Abstract The aim of this study was to evaluate the seroprevalence and factors associated with the presence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies in sheep from Paraná state. The detection of antibodies for T. gondii and N. caninum was performed by homemade and commercial indirect...

Abstract The objective of this research was to evaluate the control of coccidiosis in the litter of commercial poultry housing in the Western region of Paraná, Brazil, which adopts sanitary management to control Salmonellosis. Three litter treatments were selected, proposed by an integrating company in ...
Abstract Between December 2016 and April 2017, a spate of abortions occurred in a closed dairy herd from the central eastern region of Paraná, Brazil, in which 75 cows aborted. To identify its cause, organ fragments were collected from an aborted fetus for histopathology, and the blood samples from a st...

Abstract Aimed with this study to evaluate vertical transmission of Neospora caninum in naturally infected sheep and to monitor the kinetics of antibodies against this protozoon in their lambs. Therefore, 48 pregnant ewes, from five herds, were divided into two groups: G1 - positive for anti-N. caninum a...

Abstract Autophagy plays an important role in maintaining cell homeostasis through degradation of denatured proteins and other biological macromolecules. In recent years, many researchers focus on mechanism of autophagy in apicomplexan parasites, but little was known about this process in avian coccidia....

Abstract Coccidiosis, a disease caused by the parasitic Eimeria spp., affects birds of all ages, particularly young birds more intensely. Infected poultry presents significant economic losses. Bacillus thuringiensis var israelensis (Bti) is a Gram-positive, spore-forming bacterium that produces proteins ...
The aim of this study was to investigate the presence of anti-Neospora caninum antibodies in Girolando cows, in order to evaluate the association between seropositivity and reproductive disorders. Blood samples were collected from 40 dairy cows in their reproductive phase from the cranial superficial epi...
