“…These cases show that toxoplasmosis in humans can also occur in the Arctic regions, although infections in these areas are rarer than in regions with hot and humid climates. In addition, there is a cumulative effect over time in wildlife, resulting in an increased prevalence of infection (Omata et al 2005a(Omata et al , 2005bAnwar et al 2006;Ryser-Degiorgis et al 2006).…”

Bovine neosporosis caused by Neospora caninum is among the main causes of abortion in cattle nowadays. At present there is no effective treatment or vaccine. Serological evidence in domestic, wild, and zoo animals indicates that many species have been exposed to this parasite. However, many aspects of the life cycle of N. caninum are unknown and the role of wildlife in the life cycle of N. caninum is still not completely elucidated. In North America, there are data consistent with a sylvatic cycle involving white tailed-deer and canids and in Australia a plausible sylvatic cycle could be occurring between wild dogs and their macropod preys. In Europe, a similar sylvatic cycle has not been established but is very likely. The present review is a comprehensive and up to date summary of the current knowledge on the sylvatic cycle of N. caninum, species affected and their geographical distribution. These findings could have important implications in both sylvatic and domestic cycles since infected wildlife may influence the prevalence of infection in cattle farms in the same areas. Wildlife will need to be taken into account in the control measures to reduce the economical losses associated with this important disease in cattle farms.

“…caninum may be congenitally transmitted in deer as in bovine infections (Dubey et al, 1999) and may therefore cause significant direct or indirect economic losses for producers. In Japan, brains from sika deer examined for N. caninum DNA by polymerase chain reaction (PCR) assays tested negative (Omata et al, 2005). Otherwise, little is known about N. caninum infection in sika deer, especially in China.…”
