Evaluation of the card agglutination test (CATT/T. evansi) for detection of Trypanosoma evansi infection in water buffaloes (Bubalus bubalis) in Egypt.
A card agglutination test (CATT/T. evansi) was evaluated for detection of antibodies against Trypanosoma evansi (T. evansi) in experimentally and naturally infected buffaloes. Four calves were inoculated with a strain of T. evansi isolated from a dromedary camel. Parasitological examination of the calves revealed trypanosomes in the blood from days 4 to 9 post-inoculation (PI). General emaciation appeared from day 26 PI and aggravated until the end of the experiment (day 88 PI). Antibodies against T. evansi were detectable from day 8 PI till the end of the experiment. Parasitological examination of 200 water buffalo blood samples obtained from slaughterhouses revealed negative results. Serological examination of these animals showed that 48 (24%) water buffaloes had anti-T. evansi antibodies.
