通过对坦桑尼亚坦加地区小型奶牛场饲养年限不到10年的牲畜群进行纵向研究，估计蜱传疾病（TBD）的发病率和潜在决定因素。在研究期间，血清学试验、血液和淋巴结涂片联合用作诊断试验。从1999年8月至2001年7月，共跟踪了549只猪的动物年。总体发病率和死亡率（全因）分别为8.26和12.0/100动物年。其中56%归因于TBD（37.5%-东海岸热（ECF）），估计ECF的特定发病率和死亡率分别为3.57和4.51/动物年风险，无形体病的风险分别为2.21和2.25/100只动物。对死亡存活时间的分析表明，小牛
The incidence and potential determinants of tick borne diseases (TBDs) were estimated a longitudinal study that was conducted in cohorts of youngstock animals of less than years kept in smallholder dairy farms in Tanga region, Tanzania. A combination serological tests, blood and lymph node smears were used as diagnostic tests for during the study. A total number of 549 youngstock were followed for a total of animal years from August 1999 to July 2001. Overall morbidity and mortality rates (due all causes) were 8.26 and 12.0 per 100 animals year at risk, respectively. Of the total 56% were attributed to TBDs (37.5%-East Coast fever (ECF) and Specific morbidity and mortality rates for ECF were estimated to be 3.57 and 4.51 per animals year risk, respectively, and for anaplasmosis 2.21 and 2.25 per 100 animals risk, respectively. Analysis of survival times to death indicated that calves
