“…Although the breed predisposition of cattle to neosporosis is not documented, milk-and meat-producing cattle frequently differ in their rate of infection -as observed in the present study -, seroprevalence being (often approximately twice) higher in dairy than in beef herds (Quintanilla-Gozalo et al, 1999). This is most likely a consequence of respective management systems, i.e.…”

In order to assess the seroprevalence of bovine neosporosis with indirect fluorescent antibody test (IFAT), blood samples were collected randomly from 1063 beef and dairy cattle belonging to 12 different breeds in Northeast Hungary. Antibodies to Neospora caninum were detected in 27 (2.5%) of the animals, kept on 19 of the 42 settlements included in this survey. Since samples were collected on 50 farms, herd prevalence amounted to 38%. The percentage of cattle with seroconversion increased with age, suggesting a postnatal source of infection. The highest rate of positivity was detected in Aberdeen Angus (3.3%) and HolsteinFriesian cows (3.2%), and the lowest in Limousine (0.9%), but no breed predisposition was statistically substantiated. Neosporosis was more prevalent in dairy (3.4%) than in beef (1.9%) cattle, although the difference was not significant. Only three out of the seropositive cows, all of them Holstein-Friesians, had a history of abortion.

Finding ofNeospora caninumin the wild brown rat (Rattus norvegicus)

et al. 2004

-Nine rats (16.4%) out of 55 (Rattus norvegicus) from cattle farms were seropositive to Neospora caninum. Two of the seropositive rats were also PCR positive but all were negative by immunohistochemistry and PAS staining. The brains of all the captured rats were homogenized and initially inoculated intraperitoneally into nude mice or into SPF ICR mice, which had been immunosuppressed with prednisolone. One mouse that was inoculated with brain material from a seropositive rat became infected with N. caninum, as demonstrated by the presence of a tissue cyst in the brain and confirmed by immunohistochemistry and PCR. This is the first finding of N. caninum in naturally infected farm rats. The findings show that natural N. caninum infection occurs in wild brown rats and thus rats may serve as a reservoir for the protozoan on the cattle farm.

“…It was shown that N. caninum detected in cows had 12.5% serological positivity in England and Wales (14), 36.8% in Spain (40), 15.5% in Poland (9), 56.9% in Argentina (38) and 59% in Mexico (48). Studies regarding T. gondii have been related mostly to sheep.…”

This study was aimed at determining the existence of Neospora caninum and Toxoplasma gondii in aborted bovine foetuses. In this research, 102 bovine foetuses were examined by duplex PCR, immunohistochemistry and immunofluorescence to determine the presence of N. caninum and T. gondii. None of the aborted bovine foetuses were shown to have T. gondii, but N. caninum was detected in 26 foetuses (25.49%) by duplex PCR, in 18 (17.64%) by immunohistochemistry and in 8 (7.84%) by immunofluorescence. Moreover, 16 livers, 13 kidneys, 12 spleens, 8 thymuses and 5 brains of the 18 foetuses examined by immunohistochemistry showed immunopositivity. Positive staining was found in the spleen of eight foetuses by the immunofluorescence method. In this study, immunohistochemistry was shown to be superior to immunofluorescence in terms of diagnosis. Although immunofluorescence has the advantage of being the easiest to use in practice, it makes diagnosis more difficult because of its non-specific staining.
