title: Prevalence of blood parasites in cattle from wilayates of Annaba and El Tarf east Algeria.
abstract: Between June and September 2002, a preliminary study was conducted to assess the prevalence of blood parasites of cattle in eastern Algeria. Fifty-four bovines of different genotypes were submitted to clinical examination. From each animal, blood smears were made and stained by Giemsa. Four species of parasites, namely Theileria annulata, T. orientalis, Babesia bovis and Anaplasma marginale were encountered. Fifty animals carried single or multiple infections with blood parasites and four were found negative. The rate of single infections (72.3%, n = 39) was almost three times higher than multiple infections (20.3%, n = 11). The high percentage of single infections was recorded with T. annulata (53.7%). However single infection with Anaplasma marginale (7.4 %), B. bovis (5.6%) and T orientalis (5.6%) were very low compared to T. annulata infection. The rates of mixed infection were as follows: T. annulata/A. marginale 9.3%, T. annulata/T. orientalis 5.6%, A. marginale/T. orientalis 3.7% and B. bovis/A. marginale 1.9%.
