Combined histological examination and avidin-biotin immunohistochemical staining of formalin-fixed brain and myocardium from aborted bovine foetuses presented to the Allerton Regional Veterinary Laboratory were utilized for the diagnosis of bovine neosporosis. Two out of 144 cases were diagnosed positive for neosporosis, indicating a low prevalence of infection and confirming Neospora caninum t...

The phylogenetic relationships amongst Hammondia, Neospora and Toxoplasma were investigated by DNA sequence comparisons of the D2/D3 domain of the large subunit ribosomal DNA and the internal transcribed spacer 1. The results obtained allow us to reject the hypothesis that N. caninum and H. heydorni are the same species and show that Hammondia hammondi is probably the sister taxon to Toxoplasma...

A 16-day-old white rhinoceros calf died suddenly while in excellent condition and showing no obvious previous clinical signs. It was the 9th calf of a mature female kept free-ranging with 11 other rhinoceros as well as various other game species on a 2000 hectare game breeding centre adjacent to the town of Lichtenburg and outlying cattle farmlands in the Northern Province. At post mortem exami...

Aim: This cross-sectional survey was conducted to detect antiN. caninum antibodies in bovine dams' sera samples in nine States of the Sudan. Materials and Methods: Two hundred and seventy six bovine dams' sera samples collected from nine States in the Sudan were screened for anti-Neospora caninum antibodies using a commercial competitive ELISA (cELISA) kits. Results: The results showed an overa...

Abstract Background Toxoplasma gondii and Neospora caninum are important protozoan parasites with worldwide distribution among warm-blooded animals. Moreover, T. is a zoonotic parasite that infects humans. Poultries intermediated hosts of N. . However, little known about the contamination poultry eggs these parasites. We aimed to investigate molecular frequency chicken, domestic duck, quail fro...

Neosporosis, a parasitic infection caused by Neospora caninum (N. caninum), is one of the main contagious factors that cause reproductive disturbances in cattle and neuromuscular complaints dogs. This review was performed to determine prevalence dogs neosporosis Iran. Data were systematically gathered from January 2004 July 2020 Islamic Republic Iran following electronic databases: PubMed, Goog...

Neospora caninum, the causative agent of neosporosis, is a protozoan parasite responsible for high rate of abortion in cattle worldwide. In dogs, consequences of infection vary from severe neuromuscular disorders to asymptomatic infection and shedding of environmentally resistant oocysts. In this study, we determined the occurrence of N. caninum antibodies in dairy cattle and dogs in Vojvodina ...

Neosporosis is a disease caused by the protozoon Neospora caninum that leads to significant economic losses in many countries. In the present study, we report on use of the recombinant protein NcSRS2 of N. caninum expressed in Pichia pastoris in an indirect immunoenzymatic assay (ELISA) for diagnosing neosporosis infection in sheep and dogs. We observed that the ELISA test yielded specificity o...

Despite the enormous economic importance of Neospora caninum related veterinary diseases, the number of effective therapeutic agents is relatively small. Development of new therapeutic strategies to combat the economic impact of neosporosis remains an important scientific endeavor. This study demonstrates molecular, structural and phenotypic evidence that N. caninum calcium-dependent protein ki...
