Summary
Equines are particularly susceptible to infection withTrypanosoma evansi andT. brucei, but rarely is naturalT. congolense andT. vivax infection seen in horses. An outbreak of trypanosomosis occurred in a herd of horses used for patrolling the pineapple fields on the Del Monte Farm, Thika, Kenya initially involving 6 horses. On subsequent screening of the entire group,T. brucei,T. congolense andT. vivax infections were detected in 16 of the 35 horses. The tests used for diagnosis included microscopic examination of stained blood smears, buffy coat technique, mouse inoculation and antigen detection enzyme immunoassay (antigen ELISA).
Résumé
Les équins sont particulièrement sensibles aux trypanosomoses àT. evansi etT. brucei mais les infections àT. congolense etT. vivax sont rarement rencontrées chez les chevaux. La trypanosomose est apparue dans un groupe initial de six chevaux utilisés pour surveiller les champs d'ananas de la ferme Del Monte, à Thika, au Kenya. A la suite de la mise à l'écart de tous les chevaux, les infections àT. brucei,T. congolense etT. vivax ont été décelées chez 16 des 35 chevaux. Les tests utilisés pour le diagnostic comprenaient l'examen microscopique de frottis sanguin coloré, la centrifugation en microtubes à hématocrite, l'inoculation aux souris et la détection d'antígèns par le test ELISA.
Resumen
Los caballos son particularmente susceptibles a infecciones porTrypanosoma evansi yT. brucei. pero raramente a infecciones porT. congolense yT. vivax. Un brote ocurrió en un grupo de caballos utilizados para patrullar los campos de piña en la finca Del Monte en Kenia; inicialmente enfermaron seis caballos. Examinados todos los caballos del grupo, se encontraronT. brucei,T. congolense yT. vivax en 16 de 35 caballos. Las pruebas utilizadas para el diagnóstico incluyeron el examen microscópico de frotis de sangre coloreada, la técnica del sobrenadante en tubo capilar centrifugado, inoculatión de ratones y detección de antígeno mediante la prueba ELISA.
