A total of 475 bovine sera collected in 1995-1996 from 10 areas belonging to two different bioclimatic strata were tested for antibody activity to Babesia bigeminaand Babesia bovisusing indirect immunofluorescence (IIF). In the Gharb, the B. bovisseroprevalence was 21.7 and for B. bigemina, 10.8. The infection rate for either or both species as determined microscopically with Giemsa-stained blood films was 18.9. The Tiflet area was considered an endemic focus, and the seroprevalence was 42.2 for B. bovisand 40 for B. bigemina. The infection rate by stained blood film microscopy was 66.6. In the Haouz region, only B. boviswas found, and the seroprevalence was 10.1 with 9.4 microscopically positive blood films. More than 80 of the cattle surveyed were infested by ticks and the mean infestation rate was 36 ticks per animal and 21 ticks per animal in the Gharb and Haouz, respectively. Six species were identified. Hyalomma marginatum, Hyalomma detritum, Hyalomma anatolicum Rhipicephalus bursa, Rhipicephalus sanguineousand Boophilusannulatus. Boophilus annulatuswas found in both regions with high prevalence in the Gharb (31.3). No further correlation was made between the identified species as vectors and the presence of B. bovisand B. bigeminain these areas. |
