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...

The prevalence of gastrointestinal parasites in dogs was studied in the province of Córdoba (southern Spain), with special attention to those parasites that can be transmitted to man. The experiment was completed with the examination of soil samples from public parks and city gardens. The study was carried out over a population of 1800 animals entered in the Control Animal Centre (CECA) by copr...

Parasitic diseases of camels are major causes of impaired milk and meat production, decreases in performance or even death. Some camel parasites also represent a threat to human health. About 171,500 one-humped camels (Camelus dromedarius) and 100-300 two-humped camels (Camelus bactrianus) live in Iran. Knowledge of the biodiversity of their parasites is still limited. The present review covers...

Cyst-forming coccidia of the genus Sarcocystis (Alveolata: Apicomplexa: Coccidea) parasitize vertebrates worldwide. Data from the small subunit rRNA genes (SSU) and the D2 domain of the large subunit rRNA genes were used to reconstruct phylogeny for all species in the Sarcocystidae for which sequences are currently available. We have focused on the evolutionary history of species that circulate...

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 ...

Domestic dog (Canis domesticus) and the coyote (Canis latrans) are the only known definitive hosts for the protozoan Neospora caninum that causes abortion in dairy cattle. In the present study, antibodies to N. caninum were sought in three species of wild canids, Cerdocyon thous, Lycalopex gymnocercus and Dusicyon vetulus from Brazil. Antibodies to N. caninum were assayed by the indirect fluore...
