“…This information would have been valuable for developing disease control strategies. The observed overall seroprevalence of antibodies to E. ruminantium in this study is relatively higher than the 62% and 51.6% reported in sheep by Wesonga et al (2006) in Pastoral community area in Kenya and Faburay et al (2005) in Gambia, West Africa, respectively. Ahmadu et al (2004) in Zambia reported a goat seroprevalence of 40%, and in Zimbabwe a goat seroprevalence range of 67% to 100% on free range flocks was reported by Peter et al (2001) and Kakono et al (2003).…”

“…This was similar to past finding, where sheep were found to be severely affected than goats (Njenga and Mugera 1989). Goats were reported to be commonly affected by peracute form of the disease but sheep usually suffer from an acute or chronic form (Njenga and Mugera 1989).The variation could also be attributed to differences in feeding habits of the two animal species where goats are mainly browsers while sheep are grazers and have wool to which ticks can easily attach compared to the hair of goats (Wesonga et al 2006).…”

Sera from 497 sheep and 555 goats collected in a cross sectional study from different geographical locations in north-eastern Tanzania were examined for antibodies to Ehrlichia ruminantium using MAP 1-B ELISA technique. E. ruminantium antibodies were found in 68.6% (341/497) of sheep and 64.7% (359/555) of goats. Overall seroprevalence was 66.5% (700/1052). Infection rates were higher in sheep than goats (P < 0.05), in pastoral than in agro-pastoral production systems (P < 0.05) and in female sheep than males (P < 0.05). (131/143) 91.6% of the farms/flocks tested revealed sero-positive animals. E.ruminantium infections were found in all the geographical villages and districts tested. The infection rates per administrative district varied from 36.4% (Muheza) to 90% (Mkinga) in goats and from 11.9% (Muheza) to 94.6% (Mkinga) in sheep. The results shows E. ruminantium infection was prevalent and widely but unevenly distributed throughout the eight districts under study. These findings should be taken into consideration when future disease control and livestock upgrading programs are implemented.

Background Surveillance data documenting tick and tick-borne disease (TBD) prevalence is needed to develop risk assessments and implement control strategies. Despite extensive research in Africa, there is no standardized, comprehensive review. Methods Here we tackle this knowledge gap, by producing a comprehensive review of research articles on ticks and TBD between 1901 and 2020 in Chad, Djibouti, Ethiopia, Kenya, Tanzania, and Uganda. Over 8356 English language articles were recovered. Our search strategy included 19 related MeSH terms. Articles were reviewed, and 331 met inclusion criteria. Articles containing mappable data were compiled into a standardized data schema, georeferenced, and uploaded to VectorMap. Results Tick and pathogen matrixes were created, providing information on vector distributions and tick–pathogen associations within the six selected African countries. Conclusions These results provide a digital, mappable database of current and historical tick and TBD distributions across six countries in Africa, which can inform specific risk modeling, determine surveillance gaps, and guide future surveillance priorities.
