Prevalence of Neospora caninum and Toxoplasma gondii Antibodies and DNA in Raw Milk of Various Ruminants in Egypt

Abstract: The prevalence of Neospora caninum and Toxoplasma gondii antibodies in raw milk samples was estimated in different ruminants and Egyptian governorates. Of 13 bulk milk samples tested by ELISA, five (38.5%) were positive for antibodies to N. caninum, and two samples were additionally positive for antibodies to T. gondii, resulting in a seroprevalence of 15.4% for both T. gondii and co-infection. In individual milk samples (n = 171) from the same bulks, antibodies to N. caninum were detected in 25.7%, to T. gond… Show more

“…For instance, using a TgSAG2t-ELISA, 10.8% of the cattle sera from the Delta region ( 23 ), and 23.6% of the cattle from Qena, Kafr Elsheikh, and Minoufia tested positive ( 19 ). In Shebein El-Kom, molecular detection in cattle milk revealed 19.35% (6/31) positive for T. gondii DNA ( 30 ), while one in ten bulk milks tested positive for T. gondii DNA in a recent study ( 26 ). Cattle meat samples from Sohag city showed 31.3% positive by PCR ( 20 ).…”

“…In comparison to the previous studies on N. canimum in cattle in Egypt, this work reported a similar prevalence rate (24.6%) to the 20.43% reported in cattle of the Delta region ( 23 ), a neighboring region of Beheira governorate, and also to the 18.9% in cattle from southern Egypt ( 24 ). Recently, three of ten bulk milks from different farms and different regions in Egypt were shown to contain antibodies to N. caninum , and one of these bulk milks was additionally positive for N. caninum DNA ( 26 ). For other livestock like camels, variable seroprevalences of 3.6% ( 37 ), 11% ( 21 ), and 25.7% ( 25 ) have been reported.…”

“…Thus, we deemed that such a panel of samples would be appropriate for the evaluation of our tested method (serum ELISA kit, (ID. Vet, Grabels, France)) [18]. Generally, the availability of samples based on animal owners' cooperation determined the currently used numbers of samples which were collected randomly.…”
