“…Similarly, to the findings of Oliveira, et al 24 , N. caninum prevalence rate was greater among water buffaloes kept with close contact with pet dogs. This could be attributed to dogs consuming aborted materials and consequently shedding infective oocyst which contaminate food and play a significant role in horizontal spreading of N. caninum infection to vulnerable animals 57 .…”

“…In the present study, the overall seroprevalence rate of N. caninum in water buffaloes was 31.3%, falling within the previously reported range (27.5% to 35.4%) in Brazil 24,25 . The reported seroprevalence rate for neosporosis in the current survey was higher than those reported in in Vietnam (1.05%) 26 , Thailand (9.1-16.7%) 27 , India (9.9%) 28 , Iran (19.3%) 29 and Mexico (24.3-41.2%) 30,31 .…”

“…In addition, the rearing systems, geographic location, and farm management were varied in different countries 15,37,[39][40][41][42][43][44] . Furthermore, comparing studies is challenging since researchers use varied sample criteria, serological procedures, and cut-off values, particularly for the immunofluorescence antibody test 24 .…”

Neosporosis is a parasitic disease that causes reproductive disorders in animals, making it a barrier to maximum efficiency. The purpose of this study was to determine the seroprevalence ofNeosporacaninum(N.caninum) antibodies in water buffaloes from four governorates in northern Egypt. A commercial indirect-ELISA test was used to detect antibodies againstN.caninumin the serum of 450 water buffaloes. The total seroprevalence ofN.caninumin water buffaloes from Egypt was 31.3%, and the highest prevalence was observed in Gharbia governorate. The identified risk factors forN.caninuminfections in water buffaloes were sex (OR = 1.96, 95%CI: 1.22−4.17), buffaloes more than 4 years of age ( OR = 5.80, 95%CI: 2.26−14.86), abortion in second trimester (OR = 16.48, 95%%CI: 2.99−34.03), history of abortion (OR = 3.45, 95%CI: 1.58−7.52) and contact with dogs (OR = 2.55, 95%CI: 1.51−4.32). Thus, more studies are needed to determine the role of buffaloes in the epidemiology of neosporosis in Egypt.

“…In female water buffalo from Brazil, the risk factors associated with neosporosis were grazing and animals derived from animal markets and/or reputable sellers ( 70 ), reinforcing the hypothesis of postanal transmission due to the ingestion of food or water contaminated with oocysts. By logistic regression analysis, the presence of pigs was considered as a risk factor for neosporosis in buffalo in Paraíba state, Brazil ( 21 ), although pigs do not play an important role in the epidemiology of N. caninum .…”

A Review of Toxoplasmosis and Neosporosis in Water Buffalo (Bubalus bubalis)

et al. 2020

Toxoplasmosis and neosporosis are diseases with worldwide distribution that are associated with reproductive problems in livestock and responsible for economic losses. This review presents an overview of the current knowledge relative to these diseases in water buffalo (Bubalus bubalis). In general, buffalo are considered resistant to clinical toxoplasmosis because there are studies only reporting serological evidence of natural infection in these animals. Studies have described age, poor hygienic status of the farm, and presence of cats as risk factors for the development of Toxoplasma gondii infection in buffalo. It must be highlighted that buffalo meat, which does not receive adequate freezing treatment, could be a potential source for toxoplasmic human infection as well as the importance of raw buffalo milk in the transmission of toxoplasmosis to human beings. Neospora caninum is considered one of the major causes of abortion and responsible for huge economic losses in cattle. Vertical transmission is the main route to infect calves, and is responsible for maintaining the parasite within a herd. In buffalo, vertical transmission is also described; moreover, although there are indications that N. caninum may be associated with abortion in dairy buffalo, the reproductive importance of neosporosis is apparently lower in buffalo relative to cattle. Most studies have identified a higher time of exposition to N. caninum oocysts relative to age. The household system was also described as a risk factor for infection, possibly due to persistent contact between the home-raised buffalo and canids. The fetal immune competence of buffalo is similar to bovine, and buffalo fetus are highly susceptible to infection during the first trimester of pregnancy, indicating that N. caninum may be an abortigenic agent in buffaloes. Alternatively, it is interesting to note there is evidence that the inflammatory response in pregnant buffalo infected with N. caninum is mild enough to avoid abortion in most cases. It is proposed that the possible transmission of toxoplasmosis through unprocessed milk and buffalo meat may occur, which is important in terms of public health. Additionally, there is strong evidence to suggest that N. caninum may be associated with abortion in buffalo.

“…It is noteworthy that the serological condition of the acquired cattle was unknown to the purchasers. According to Oliveira et al (2018), when buffaloes of unknown health status were purchased, movement of infected individuals between herds was promoted. In the Kalunga community, cattle trading among its residents predominated (Baiocchi, 2013), and this transit of seropositive animals reinforced the presence of this coccidian in and around the Kalunga area.…”

Little is known about Toxoplasma gondii infection among cattle living in the Cerrado (Brazilian savanna) biome in Brazil. In particular, there is no epidemiological data relating to infection in quilombo lands, i.e. areas settled by Afro-descendants of escaped slaves. The aim of this study was to determine the prevalence, spatial distribution and risk factors associated with T. gondii infection among cattle in the Kalunga quilombo, in the Cerrado biome. Blood samples were collected from 1533 cattle for antibody detection using the indirect fluorescence antibody test (IFAT). The study area was subdivided into five macroregions to determine the spatial distribution of infection. An objective questionnaire was applied to the cattle owners to evaluate risk factors, which were analyzed using univariate analysis and logistic regression. The prevalence of T. gondii infection among cattle was 8.93% (137/1533), and antibodies were found in 49.6% of the herds (66/133), in all macroregions. The risk factors associated with T. gondii infection in cattle were the following: number of animals in the herd (OR: 30.56), purchase of cattle (OR: 2.57), age group (OR: 1.95) and average annual temperature (OR: 1.77). Thus, the occurrence rate, spatial distribution and risk factors associated with T. gondii infection among cattle in the Kalunga quilombola community are documented here, for the first time.
