“…Em testes com uso de RIFI realizados em búfalos no Irã (Navidpour & Hoghooghi-Rad 1998) e em São Paulo (Souza et al 2001), foram encontrados respectivamente com 8,8% (≥16) e 49,9% (≥64) de animais reagentes para anticorpos anti-T. gondii. Na presente pesquisa, apenas uma (0,27%) búfala apresentou anticorpos IgG anti-N. caninum e anti-T. gondii na RIFI com títulos 200 e 64, respectivamente.…”

Para determinar a ocorrência de anticorpos IgG anti-Neospora caninum e Toxoplasma gondii em 14 unidades produtivas de búfalos, situadas em 13 municípios no estado do Pará, foram coletadas amostras de soro sanguíneo de 374 fêmeas adultas. Os soros foram submetidos à reação de imunofluorescência indireta (RIFI), utilizando-se os títulos 200 e 64, respectivamente como ponto de corte para N. caninum e T. gondii. Obteve-se 153 (40,9%) de animais soropositivos para N. caninum com 100% das propriedades com focos da infecção, enquanto que quatro búfalas (1,1%) foram soropositivas em quatro fazendas para T. gondii e uma búfala (0,27%) foi soropositiva para ambos parasitos. A presença de anticorpos é um indicativo da circulação desses protozoários em búfalos das propriedades estudadas, representando uma fonte de infecção para outros animais, assim como o possível envolvimento em distúrbios reprodutivos nessa espécie.

“…Comparatively, lower seroprevalence rates of 4.8%, 10.75%, 2.60%, 3.86%, and 5.70% have been found in Iran [20], Egypt [21], Malaysia [22], Korea [23], and China [24], respectively. Varying rates of seroprevalence in buffaloes have also been reported by various researchers in several countries, including 20.4% in Afghanistan [25], 3% in Vietnam [26], 8.8% in Iran [12], 30% in Iraq [11], 2.9% in India [27], and 7.8% in Trinidad [13]. Various risk factors (age, sex, breed, diagnostic test, and climatic variations) may contribute to the differences in seroprevalence in the current study and other studies of the world.…”

“…The risk of toxoplasmosis is high in countries like Pakistan due to a lack of modern farming techniques. Several studies conducted in different parts of the world, including those conducted in Morocco [9], Thailand [10], Iraq [11], Iran [12], and Trinidad [13], have reported a prevalence of toxoplasmosis in cattle and buffaloes.…”

Introduction: Toxoplasmosis is a widespread zoonosis that causes significant economic losses due to abortions and other developmental disabilities in livestock animals. The objectives of the current study were to determine the prevalence and associated risk factors of Toxoplasma gondii infection in cattle and buffaloes in northern parts of Punjab, Pakistan, where no such work previously existed. Methodology:Serum samples obtained from 400 cattle and 422 buffaloes present on different private and government-owned farms were tested for anti-Toxoplasma IgG and anti-Toxoplasma IgM antibodies by using enzyme linked immunosorbent assay (ELISA). Additional data, including water sources, hygienic status at the farm, management practices, size of the herd, and presence of cats in the vicinity of the farm were obtained using a questionnaire in surveys and interviews. Results: The overall prevalence of infection was 19.75% (79/400) in cattle and 15.16% (64/422) in buffaloes. IgG antibodies were found in 75 (18.75%) cattle and 58 (13.74%) buffaloes, while IgM antibodies were found in 9 (2.25%) cattle and 10 (2.37%) buffaloes. Seroprevalence was significantly higher in females and older animals of both species. Seroprevalence was found to be associated with poor hygienic conditions, extensive management practices, and presence of cats in the surrounding areas. No difference of seroprevalence was observed with respect to different breeds, location, water source, and herd size. Conclusion: The present study found that T. gondii is prevalent in large ruminants in northern Punjab, and may have important implications for the livestock industry and public health.

“…Seroprevalence studies for N. caninum in buffaloes showed a positivity ranging from 1.5% to 70.9% and are described in southeastern and northern region of Brazil (Fujii et al 2001, Gennari et al 2005, Argentina (Campero et al 2007, Konrad et al 2013, Egypt (Dubey et al 1998), India (Meenakshi et al 2007), Vietnam (Huong et al 1998), and Italy (Guarino et al 2000).

ABSTRACT.-Portella L.P., Cadore G.C., Lima M., Sangioni L. The presence of antibodies against Neospora caninum, Sarcocystis spp. and Toxoplasma gondii was evaluated in buffaloes (Bubalus bubalis) from Rio Grande do Sul state (RS), southern Brazil. Serum samples (n=220) were analyzed for antibodies by indirect fluorescent antibody test (IFAT). Antibody presence was considered when the titers were equal or higher than 100 for these protozoa. A total of 60.5% (133/220) buffalo serum samples were positive for at least one of the protozoa evaluated in this study. Antibodies for N. caninum, Sarcocystis spp. and T. gondii were found in 36.4% (80/220), 25.5% (56/220) and 16.8% (37/220) of the buffaloes respectively, indicating a higher frequency of N. caninum infection (p=0.0133). The IFAT is a suitable method to diagnose N. caninum, Sarcocystis spp. and T. gondii infection in buffaloes for detecting IgG antibodies. This study demonstrates the presence of these three protozoa in buffalo herds in RS, Brazil, which may be source of infection to other animals. The high frequency of animals positive for N. caninum is important and could be related to reproductive problems. Additionally, the presence of Sarcocystis spp. and T. gondii in buffaloes can be a possible public health issue.
