“…The higher prevalences documented in older dogs suggest most of them become infected after birth. In the present study, as well as in some others [10, 11, 13], no significant differences were observed between young and old animals. Nevertheless, it is important to point out that the number of dogs in the young group (i.e., 2–11 months old) was smaller than the adult group.…”

Neosporosis, caused by Neospora caninum, is an important cause of abortion in cattle and of neurological disease in dogs. This study investigated the prevalence and correlates of antibodies to N. caninum in 441 dogs from the five regions of mainland Portugal. A commercial competitive enzyme-linked immunosorbent assay (cELISA) was used and specific antibodies were detected in 35 (7.9%) dogs. Seroprevalence levels were significantly different among some of the studied regions, as well as between stray dogs (13.6%) and hunting dogs (1.7%). The difference between seropositivity in dogs presenting musculoskeletal or neurological signs (21.4%) and that in animals without clinical signs compatible with neosporosis (5.6%) was close to statistical significance. This is the first report on the seroprevalence of N. caninum in dogs in Portugal. Neosporosis should be considered in the differential diagnosis of neurological disorders of dogs.

“…We didn’t test the second batch samples because of non availability of reagents for testing of N. caninum by NAT, or IFA, or cELISA in China. Compared with other countries [10-13], the prevalence of N. caninum antibody was low in East Asia [14,15]; also it is low in this study. Although a comparison of different serological tests (NAT, IFA, cELISA) for the detection of N. caninum antibodies in dogs has not been made, it is generally accepted that results by NAT and IFA are comparable because both tests assess antibodies directed against whole tachyzoites [1].…”

Low prevalence of Neospora caninum and Toxoplasma gondii antibodies in dogs in Jilin, Henan and Anhui Provinces of the People’s Republic of China

BackgroundNeospora caninum and Toxoplasma gondii are important pathogens of worldwide distribution. N. caninum is a major cause of abortion in cattle and dogs are main reservoirs because they excrete the environmentally resistant oocysts. Toxoplasmosis is a worldwide zoonosis and dogs are considered as sentinels for this parasite because of their close contact with people and cats; additionally dog meat is also used for human consumption in China. The aim of the present study was to assess the prevalence of N. caninum and T. gondii infection in dogs from China. A total of 425 countryside dog hearts in Jilin, Henan and Anhui provinces of the People’s Republic of China were collected from slaughter houses in two batches; the first batch of 96 in October 2013, and the second batch of 329 in April 2014. Serum samples extracted from 96 dog hearts were tested for antibodies to N. caninum and from 425 dog hearts were tested for T. gondii antibodies in the modified agglutination tests (cut-off 1:25 for both), using respective antigens.ResultsAntibodies to N. caninum were 6 of 96 (6.25%) of dogs with titers of 1:25 in 2, 1:50 in 3, and 1:100 in 1. All seropositive dogs were more than 1 year old. Antibodies to T. gondii were found in 35 of 425 (8.24%) dogs with titers of 1:25 in 15, 1:50 in 14; and 1:100 in 6.ConclusionThe results of the present study indicated low prevalence of N. caninum and T. gondii antibodies in dogs of China, compared with Europe and America. Identification of the risk factors that underlie these differences may help prevention of neosporosis and toxoplasmosis. This is the first report of N. caninum infection in dogs from China.

“…Only asexual life stages of N. caninum have been observed in intermediate hosts (tachyzoites and encysted bradyzoites), including cattle [5, 31]. Previous studies have shown that the prevalence of N. caninum in dogs ranges anywhere from 2.1 to 36.4% in Europe, and 0.54 to 34.91% in central China [2, 10, 11, 17, 22, 28–30].…”

Although Neospora caninum is an important veterinary pathogen, veterinarians in various areas including in Mainland China lack a full understanding of neosporosis distribution in dog populations. This study aims to determine the emergence of anti-N. caninum antibodies in canine populations classified based on breeders, herdsmen, and huntsmen in northeast mainland China. In addition, the risk factors associated with seropositivity were explored. An indirect immunofluorescent antibody test (IFAT) was performed on canine serum to determine seroprevalence. Logistic regression models were used to collect and analyze individual and management data, in order to determine high-reliability predictors of seroprevalence as well as the level of anti-N. caninum antibodies. Among the 476 dogs tested, 95 (20%) were seropositive. Mixed breed (OR 1.53), former strays (OR 1.38), dogs living on cattle farms (OR 2.30), hunting dogs (OR 1.22) as well as raw meat feeding (OR 1.66) were correlated (p < 0.05) with N. caninum infection. Interestingly, the seropositivity of dogs on cattle farms was higher (28%) than that of those (24.8%) living in breeding facilities (p < 0.05). A large number of seropositive dogs were found on cattle farms in the study region, suggesting horizontal transmission between dogs and cattle. Therefore, this source of infection should be studied further, and should be a strong consideration in differential diagnoses of dogs raised on cattle farms.
