<p>Due to the scarcity of data on the sero-positivity of anti-<i>T. gondii</i> &amp; anti-<i>N. caninum</i> antibodies and the worldwide importance of these protozoans in the Republic of Egypt, our research aimed to discover the sero-prevalence of <i>T. gondii</i> &amp; <i>N. caninum</i> in buffaloes &amp; cows from some Delta of Egypt provinces.

The overall sero-positivity of anti-<i>N. caninum</i> in cows from Gharbia, Beheira and Menoufia provinces were (22.19% for IgM) and (38.13% for IgG), respectively.

摘要

Due to the scarcity of data on the sero-positivity of anti-T. gondii & anti-N. caninum antibodies and the worldwide importance of these protozoans in the Republic of Egypt, our research aimed to discover the sero-prevalence of T. gondii & N. caninum in buffaloes & cows from some Delta of Egypt provinces. Both IgG & IgM against these protozoans were detected using specific recombinant surface Ag 2 of T. gondii (TgSAG2) & surface Ag 1 of N. caninum (NcSAG1) based ELISA. The overall sero-positivity of anti-N. caninum in cows from Gharbia, Beheira and Menoufia provinces were (22.19% for IgM) and (38.13% for IgG), respectively. While sero-positivity of anti-T. gondii in cows from the same examined provinces were (16.88% for IgM) and (31.88% for IgG), respectively. In buffaloes, the overall sero-positivity of anti- Neosporoa caninum from Gharbia, Damietta and Menoufia provinces were (6.82% for IgM) and (15.45% for IgG), respectively. While the total sero-positivity of anti-T. gondii in buffaloes from the Gharbia, Damietta and Menoufia provinces were (7.27%for IgM) and (16.82% for IgG), respectively. The rates of mixed infections were 16.56% in cattle & 9.09% in buffaloes. This study showed significant differences regarding the age; gender & season in cattle while in buffaloes significant changes were demonstrated regarding the age & season. In conclusion, toxoplasmosis and neosporosis are prevalent in cattle and buffaloes in the studied Provinces of the Delta of Egypt. In turn, these infections will represent a possible contaminated source for human infection and could affect the livestock industry development in Egypt.
