Identification and Characterization of the ATG8, a Marker of Eimeria tenella Autophagy

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....

Association between Neospora caninum seropositivity and reproductive disorders in girolando cows

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...

Neospora caninum DNA distribution in tissues of gerbils as experimental models of chronic neosporosis

Neospora caninum is the main etiologic agent of neosporosis in domestic animals and its pathogenesis comprises two characteristic phases: acute and chronic. Rodents are used as experimental models to mimic acute and chronic bovine neosporosis. In this study, we inoculated a total of 27 female gerbils, wi...

Co-infection by Neopora caninum and bovine viral diarrhea virus in cattle from Rio Grande do Sul, Brazil, destined to exportation

Pesqui. vet. bras; 40 (8), 2020
Reproductive tests in cattle are of great economic importance, given the impact it can have on the production system and may be caused by agents. Neospora caninum and Bovine Viral Diarrhea virus (BVDV) are considered of great importance as reproductive and should be considered responsible for keeping ani...

DNA extraction methods for molecular detection of Eimeria spp. in cattle and sheep

Pesqui. vet. bras; 40 (7), 2020
Molecular detection of Eimeria species in fecal samples can be useful for experimental and diagnostic purposes. However, the parasite quantity presence in feces and the oocyst wall are an obstacle in DNA extraction protocols. Therefore, adequate sampling and effective disruption of the oocysts are essent...

Causes of abortion in dairy cows in Uruguay

Pesqui. vet. bras; 40 (5), 2020
A case series study was conducted to determine the frequency of causes of abortion in dairy cattle in Uruguay. The sample size of 102 cases was composed of 53 fetuses, 35 fetuses with placentas, and 14 placentas without an associated fetus. All cases underwent gross and microscopic pathologic examination...

Ocorrência de espécies do gênero Eimeria Schneider, 1875, em cordeiros confinados

Este trabalho descreve as espécies do gênero Eimeria Schneider, 1875, que ocorreram em um confinamento de cordeiros, bem como as dinâmicas da eliminação de oocistos no ambiente, a correlação com o ganho de peso médio diário (GMD) e as variáveis climáticas, durante nove semanas. Cento e quatro ...

Vitamin B12 deficiency in newly weaned goat kids associated with clinical infection with Eimeria arloingi

Abstract A severe outbreak of diarrhea associated with poor growth was reported in ten newly weaned goat kids that originated from a research farm (Group A). Two of these kids underwent necropsy examination. Five goat kids of the same age maintained in the same pen showed no clinical signs (Group B). The...

Diversity of enteric coccidia in pigs from the Paraíba Semiarid Region of Northeastern Brazil

Abstract There is great diversity in swine coccidia, which are responsible for causing intestinal disorders ranging from sporadic diarrhea to severe cases of hemorrhagic enteritis. Thus, determining the species of coccidia that affect the animals of a region and associating them with the characteristics ...
