“…There are reports on the occurrence of canine neosporosis in various parts of the world, with seroprevalence levels ranging from 0% to 32% being reported [1,2,8,14-17]. A previous Kenyan study reported that out of 140 dogs screened, none was seropositive to NC [14].…”

Aim:The objective of this study was to determine the seroprevalence of Neospora caninum (NC) and its risk factors in farm dogs in Kenya.Materials and Methods:As part of a longitudinal study on dairy cattle abortion in 2010 in Kenya, serum samples were collected from 84 dogs in 53 randomly selected dairy cattle farms to determine the seroprevalence and risk factors of seropositivity for NC.Results:15 (17.9%) of the dogs were seropositive to NC antibodies, and at least one seropositive dog was found in 12 (22.6%) of the 53 farms. The final multivariable logistic regression model identified free-roaming as the only factor significantly associated with seropositivity (odds ratio=4.48; p=0.03).Conclusion:The findings of this study indicate that canine neosporosis does exist in Kenya and that farmers should restrict their dogs from roaming to reduce the risk of their dogs becoming a reservoir for NC. More studies need to be carried out to determine the reproductive effects of NC on dairy cattle in Kenya.

“…In this area, most of the owners allow their dogs to roam outside the home, which presumably places them in closer contact with other sources of animal products and allows exposure to T. gondii oocytes from freely roaming cats. Nevertheless, it was found that the seroprevalence of T. gondii in dogs in this area was lower than that in most other parts of China [25], perhaps because since 2002 the owners of dogs in Shanghai have been supplied a sulpha drug free of charge by the animal health authorities [16].…”

The aim of this study was to determine the seroprevalence of Leishmania infantum and Toxoplasma gondii among household dogs in Shanghai (the most important industrial and commercial city in China), and to assess the possible risk factors associated with the infection. During 2014-2015, a total of 408 sera were collected from healthy household dogs and tested for L. infantum and T. gondii infection using commercial ELISA kits. The endemic characteristics according to gender, age group and breed were revealed by statistical descriptions and inference. The positive rates of L. infantum infection (24/408, 5.9%) were lower than those of T. gondii infection (37/408, 9.1%), and co-infection with both parasites was detected in seven dogs (7/408, 1.7%). Seropositivity for either parasite was more likely associated with age: the seroprevalence of T. gondii infection ranged from 1.3% (dogs≤1 year) -18.7% (dogs>6 years), whereas that of L. infantum ranged from 1.3% (dogs≤1 year) -9.9 % (dogs>6 years). Interestingly, the rates of exposure to both L. infantum and T. gondii were higher in males than in females. Relatively higher exposure rates for L. infantum and T. gondii were also observed in crossbred dogs compared with purebred dogs. However, neither gender nor breed is likely a determining factor for infection with these two parasites (P > 0.05). Identification of the risk factors that underlie these differences may help in the prevention of L. infantum and T. gondii infection in household dogs. To the best of our knowledge, this is the first report of L. infantum and T. gondii infection in household dogs in Shanghai, which shows that these two important parasites are still prevalent in this region. Therefore, it is necessary to take integrated strategies for prevention and control of infection in animals, which could help to reduce human infection in the region. et al.

“…Antibodies to N. caninum have been reported in dogs worldwide [ 21 , 28 , 29 ]. There have also been some surveys of N. caninum infections in dogs in some provinces or cities of China in recent years ( Table 1 , [ 1 , 16 , 18 , 19 , 26 , 30 , 32 , 35 ]). However, little information is available on the epidemiology of N. caninum infections in dogs in central China.…”

Serological study ofNeospora caninuminfection in dogs in central China

Neospora caninum is a protozoan parasite that causes abortion in cattle as well as reproduction problems and neurological disorders in dogs. Dogs are important in the epidemiology of N. caninum because they act as definitive hosts, shedding oocysts in the environment. To investigate the seroprevalence of N. caninum infection in dogs in central China, 1176 serum samples were collected from domestic dogs in Henan province, central China between March 2015 and February 2016 and tested for IgG antibody against N. caninum, using the indirect fluorescent antibody test (IFAT). The overall seroprevalence of N. caninum was nearly 15% (172/1176). No significant difference was observed between this seroprevalence according to sex and breed of dogs (p > 0.05). The infection rate in rural dogs (18%) was higher (p < 0.05) than in urban dogs (11%). The prevalence of N. caninum infection in dogs increased (p < 0.05) with age. The results of the present study indicate the high prevalence of N. caninum antibodies in dogs in Henan province, central China. Sanitary conditions and animal health must be improved to prevent the transmission risk of N. caninum by dogs.
