The results of a study on the abundance of Amblyomma variegatum in different ecological zones and of Cowdria ruminantium infection rates in nymphal and adult ticks of the North Guinean zones are given. Joint research is also conducted on the evaluation of seroprevalence. In this study, it appears that the vector is most important in the North Guinean zone, followed by the South Sudan and the coastal Niayes zones. Elsewhere, the tick populations are not significant or absent. The infection rate in the North Guinean zone is high: 1.1% at least for adult ticks and 7.8% for nymphs. The seroprevalence in the North Sudan and the Sudano-Sahelian zones is very low in the hinterland whereas the values are higher near the coast.
给出了关于不同生态区变异革蜱丰度以及北几内亚地区若蜱和成蜱中反刍兽考德里氏体感染率的研究结果。还开展了关于血清阳性率评估的联合研究。在本研究中，似乎该传播媒介在北几内亚地区最为重要，其次是南苏丹和沿海尼亚耶斯地区。在其他地方，蜱虫种群数量不多或不存在。北几内亚地区的感染率很高：成年蜱至少为1.1%，若蜱为7.8%。在苏丹北部和苏丹 - 萨赫勒地区，内陆的血清阳性率非常低，而在沿海地区数值较高。
