Neospora caninum has been found to infect a wide range of animals and it has emerged as a very
important cause of abortion in cattle worldwide. In Spain, high herd seroprevalence and high percentages
of infected aborted fetuses have been observed. We revise here several epidemiological
aspects of neosporosis based on our studies in high producing dairy herds in North-eastern Spain. Our
results indicated a close relationship between mother seropositivity to N. caninum and abortion risk
and that irrespective of the herd level of Neospora-seroprevalence, plasma antibody titration against
N. caninum is a good indicator of risk of abortion; Neospora-infection does not affect fertility nor
compromises the subsequent maintenance of gestation during the first trimester of gestation in animals
chronically infected prior to pregnancy; Neospora-seropositivity can be very stable throughout
years so that chronically infected cows can show a high rate of repeat abortions; and that the use of
beef semen, especially that derived from the Limousin bulls, reduces dramatically the incidence of
abortions. The later approach has been included in the control measures for neosporosis in dairy
herds with high prevalence of N. caninum and significantly reduced both abortion and seroprevalence
levels in those herds.
