We have evaluated a new simple technique using whole blood from experimentally infected cattle for the isolation and cultivation of Theileria annulata. The study was carried out on 20 Holstein-Frisian bovines that had been experimentally infected with a virulent lethal dose of Theileria annulata. This technique has been compared to the classical peripheral blood monocyte isolation with Ficoll carried out on 22 experimentally infected Holstein-Friesian calves. The effectiveness of the reference technique was estimated to 86.4%, whilst the effectiveness of the new technique was 100%. Moreover, this new technique leads to time and money saving estimated to € 3.06 per sample. It decreases the contamination risks by reducing the steps of sample manipulation.
Résumé
Les auteurs évaluent une nouvelle technique, très simple, permettant l’isolement de Theileria annulata à partir du sang total de bovins infectés expérimentalement. Cette étude a été réalisée sur 20 bovins de race Frisonne-Holstein qui ont été infectés par un stabilat létal de Theileria annulata. Cette technique a été comparée avec la technique conventionnelle d’isolement des monocytes avec le Ficoll. L’efficacité de la technique de référence a été estimée à 86,4 %, celle de la nouvelle technique est de 100 %. De plus, cette technique permet d’économiser du temps et de l’argent (3,06 €) par échantillon. Cette nouvelle technique diminue les risques de contamination en réduisant le nombre d’étapes de manipulation des échantillons.
