Neospora caninum has been detected in several wild mammalian species, i.e., deer, coyotes, dingoes, and foxes. Farm-bred foxes were rarely reported to be affected by the parasite. In this study, we detected for the first time the infection of N.caninum in farm-bred young blue foxes (Alopex lagopus) in China. Neospora-like tissue cysts were observed in brains and kidneys of the foxes by histopat...

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...

Neospora caninum is a protozoan cyst forming apicomplexan parasite that causes neosporosis, notably in cattle (Bos taurus) and domestic dogs (Canis familiaris) [1,2]. It is closely related to Toxoplasma gondii and has emerged as a major cause of reproductive failure in cattle worldwide [2]. The parasite was first described in a dog with encephalomyelitis and myositis [1] and was later described...

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. cani...

Neosporosis is an important cause of bovine abortion worldwide. Many aspects of transmission of Neospora caninum in nature are unknown. The white-tailed deer (Odocoileus virginianus) is considered one of the most important wildlife reservoirs of N. caninum in the USA. During the hunting seasons of 2008, 2009, and 2010, brains of 155 white-tailed deer fetuses were bioassayed in mice for protozoa...

background: the aim of this study was to determine the seroprevalence of antibody to neospora can­inum in healthy and aborted dairy cattle in tabriz, capital of east-azarbaijan in northwest of iran. methods: in this cross-sectional study serum samples were collected from 266 healthy and ab­orted holestein-feriesisnc cows from september 2008 to august 2009. the sera were analyzed to de­tect of a...

Bovine Neosporosis, a disease caused by the protozoan parasite, Neospora caninum, is now recognized throughout the world. It is the major identified cause of abortion in many regions, including California. A critical feature of the disease is that the infection is maintained in cattle as a chronic, persistent infection that is efficiently passed on to the fetus during pregnancy. While fetal inf...

Neospora caninum is a worldwide distributed pathogen which causes abortion in cattle leading to economic loss in the cattle industry. The aim of this study was to determine the seroprevalence of N. caninum antibodies in the native cattle slaughtered in various areas of Kurdistan province (western Iran) from September 2010 to September 2011. Serum samples from 368 cattle slaugh...

A serological survey was conducted in the Patagonia region of Argentina to estimate the prevalence of nine disease agents within the populations of free-ranging culpeo (Dusicyon culpaeus) and grey (Dusicyon griseus) foxes. The disease agents were Aujeszky's disease virus (ADV), Brucella, canine adenovirus (CAV), canine distemper virus (CDV), canine parvovirus (CPV), Encephalitozoon cuniculi, Le...

Neospora caninum is an important cause worldwide of abortion, stillbirth and calves born weak. Abortion is the major clinical sing associated to Neospora caninum infection, it typically occurs between months four to seven of gestation, but may occur from three months to term. Abortions tend to occur during mid-gestation and it appears that foetuses exposed in early gestation are more likely to ...
