Neospora caninum is an intracellular parasite which causes abortion in cattle worldwide. This descriptive, cross-sectional study was conducted during 2009 to investigate the sero-prevalence of Neospora Caninum infection among Cattle from three climate zones of Iran. Female animals that had abortion history were sampled. Totally, 226 serum samples were collected from cattle herds living in Ardeb...

The intracellular parasite Neospora caninumis prevalent in several countries and is increasingly recognized as an important cause of abortion and stillbirth in cattle. For characterizeing the tachyzoite antigens of Neospora caninumin aborted cows, sera were obtained from 116 cows which were aborted in the third semester of the pregnancy period and had antibodies to Neospora caninumin ELISA. To ...

This study aimed to determine the prevalence and reproductive impact of Neospora caninum in a herd of semi-free-ranging Père David's deer (Elaphurus davidianus) at a conservation facility, following a suspected abortion storm in 2008. Serum samples (n=103) collected from 60 individuals between 2002 and 2011 were evaluated using competitive ELISA for the detection of N. caninum-specific antibodi...

Flourescent antibody test (FAT) was applied to determine the cross-reactivities of monoclonal (mAb), polyclonal (pAb) antibodies to Neospora, Toxoplasma and Cryptosporidium and antisera from cattle naturally infected with Neospora canium against antigens from a number of sources. Both mAb and pAb to Neospora reacted strongly (FAT titre up to 2560) with the homologous antigens and demonstrated w...

The present study showed that incorporation of CpG adjuvant into plasmid DNA coding for NcGRA7 antigen resulted in a twofold increase in the level of protection against congenital transfer of Neospora caninum. The level of protection was considerably higher than that observed in pups born from dams immunized with nonrecombinant plasmid.

Retrospective testing of 3,232 serum samples from the general population and 518 serum samples from a high-risk group showed no evidence of human exposure to Neospora caninum in England. Results were obtained by using immunofluorescence antibody testing and ELISA to analyze frequency distribution.

Neospora caninum is an important veterinary pathogen that causes abortion in cattle and neuromuscular disease in dogs. Neospora has also generated substantial interest because it is an extremely close relative of the human pathogen Toxoplasma gondii, yet does not appear to infect humans. While for Toxoplasma there are a wide array of molecular tools and reagents available for experimental inves...

Neospora caninum is an obligate intracellular parasite and is recognised as the leading cause of bovine abortion worldwide. Natural infection with N. caninum has been described in sheep but it has generally not been regarded as a significant cause of abortion. Recently, there have been several New Zealand cases of foetal abortions where N. caninum was detected which strongly suggested the invol...

BACKGROUND Because of the economic importance of the Arab race horses and also the role of Toxoplasma gondii and Neospora spp. in abortion and reproductive failure of these animals, we decided to perform this study. OBJECTIVES We designed this study to investigate the seroprevalence of anti-Toxoplasma gondii and anti-Neospora spp. antibodies in Arab horses from 12 cities of Khuzestan province...

Toxoplasma gondii, Neospora spp., Sarcocystis spp., Hammondia spp. and Besnoitia besnoiti are genetically related cyst-forming coccidia. Serology is frequently used for the identification of T. gondii, Neospora spp. and B. besnoiti-exposed individuals. Serologic cross-reactions occur in different tests among animals infected with T. gondii and H. hammondi, as well as among animals infected by T...
