Neospora caninum is associated with abortion in Algerian cattle.
Neospora caninum is a major cause of abortion in cattle worldwide. However, little information is available for Algeria. Accordingly, 799 cattle from 87 farms in the north and northeast of Algeria were enrolled in a seroepidemiological survey. An indirect fluorescence antibody test (IFAT) revealed a seroprevalence of 19.6%. The animals were divided into 3 groups according to their breed: import...
متن کاملSeroprevalence of Neospora caninum in sheep from Western Iran
Aim: The aim of present study was to determine the seroprevalence of Neospora caninum infection in aborted sheep population from Hamedan province of Iran. Materials and Methods: 358 serum samples of aborted ewes were evaluated for IgG-antibodies to N. caninum using enzymelinked immunosorbent assay (ELISA). Results: 8 samples (2.2%) were found seropositive for this infection (2.05< Confidence in...
متن کاملSerological response over time to recombinant Neospora caninum antigens in cattle after a neosporosis-induced abortion.
Recombinant Neospora caninum tachyzoite antigens were evaluated in an enzyme-linked immunosorbent assay (ELISA) for recognition by serum antibodies (Ab) from Neospora-infected cattle. Serum samples were obtained every 2 to 3 weeks for 8 to 15 months from 10 cows with histories of Neospora-associated abortion. Serum samples were also obtained from offspring of these animals and from a large numb...
متن کاملExperimental infection of sheep with Neospora caninum oocysts.
The purpose of the present study was to investigate the potential of Neospora caninum oocysts to infect sheep and determine whether N. caninum DNA could be detected by polymerase chain reaction (PCR) assay in blood and brain of sheep after oocyst inoculation. Six ewes were inoculated per os with 10(4) N. caninum oocysts, whereas 2 ewes served as uninoculated controls. All sheep were bled weekly...
متن کاملNeospora caninum and neosporosis
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...
