Abstract
Eighty-two equine sera from 13 farms in northern Colombia were examined for antibodies toBabesia caballi andB. equi using the complement fixation (CF) and the indirect fluorescent antibody (IFA) test. Seroreactors to both piroplasms were present on all farms. The IFA test indicated a prevalence of 90% forB. caballi and 94% forB. equi. The CF test detected antibodies toB. caballi in 41% and toB. equi in 65% of the animals. The prevalence of seroreactors in different age groups revealed a significant decline in CF antibodies toB. caballi in animals older than three years. IFA titres for bothBabesia spp. gradually declined with increasing age of the animals but were still present in most animals of the oldest age group (over nine years old).Anocentor nitens was found on all farms whereasAmblyomma cajennense was found only on two farms located on the coast. On a recherché sur 82 sérums de chevaux de 13 fermes de Colombie du nord les anticorps anti-Babesia caballi etB. equi par les tests de fixation du complément (FC) et d'immunofluorescence indirecte (IFA). On a trouvé des sérums positifs dans toutes les fermes. Le test IFA donne une prévalence de 90% pourB. caballi et 94% pourB. equi. Le test FC détecte des anticorps anti-B. caballi chez 41% et anti-B. equi chez 65% des animaux. La prévalence des réagissants dans les groupes d'âge montre un déclin significatif des anticorps fixant le complément pourB. caballi chez les animaux de plus de 3 ans. Les titres IFA pour les deuxBabesia spp. déclinent graduellement avec l'âge mais sont toujours présents chez la plupart des animaux du groupe le plus âgé (plus de 9 ans). On a trouvéAnocentor nitens dans toutes les fermes, maisAmblyomna cajennense dans uniquement deux fermes de la région côtière. Se examinaron 82 sueros equinos provenientes de 13 fincas en el norte de Colombia, por la presencia de anticuerpos deBabesia caballi yB. equi, mediante la fijación del complemento y la prueba indirecta de anticuerpos fluorescentes. Se encontraron seroreactores a ambos piroplasmas en todas las fincas. La prueba de anticuerpos fluorescentes reveló una prevalencia de 90% paraB. caballi y 94% paraB. equi. La prueba de fijación del complemento detectó anticuerpos deB. caballi en 41% de animales y deB. equi en 65%. La prevalencia de seroreactores en grupos de diferentes edades reveló un descenso significativo en anticuerpos fijadores del complemento deB. caballi en animales mayores de tres años. Los títulos de anticuerpos fluorescentes para ambos piroplasmas declinaron con la edad, pero siempre estuvieron presentes inclusive en animales de nueve años de edad y más. La garrapataAnocentor nitens se encontró en todas las fincas, y elAmblyomma cajennense se encontró únicamente en dos de las fincas estudiadas.Keywords
