Aiding .ck and .ck-‐borne disease control protocols Rothen, J., Bishop, R., Mwaura, S, Pﬂüger, V., Daubenberger, C., Olds, C. Delivering scienceTHE PROBLEM Tick distribu.ons are determined by clima.c factors such as temperature, precipita.on and humidity. Tick distribu.ons are shiKing drama.cally due to climate change. Consequently, the epidemiology of .ck-‐borne diseasess are changing with far reaching implica.ons for animal and human health. Maps ploMng current .ck distribu.ons in Africa are needed to understand and predict .ck-‐borne diseases. Matrix-‐assisted laser desorp.on/ioniza.on-‐Time of ﬂight (MALDI-‐TOF) mass spectroscopy is able to iden.fy .ck species cheaper and faster than other molecular techniques. ! Mapping .cks for human and livestock health ! Developing databases for .ck iden.ﬁca.on ! Developing predic.on models for .ck and .ck-‐borne disease distribu.on ! Training human and veterinary health professionals in .ck iden.ﬁca.on ! Mentoring students THE SOLUTION Collect .cks from livestock, humans and companion animals as well as ﬁeld traps. Iden.fy .cks using MALDI-‐TOF. Iden.fy any .ck-‐borne diseases present in collected .cks. Create new distribu.on maps for .ck species within Africa. Create models for further .ck and .ck-‐borne disease distribu.ons. THE PROGRESS Reference MALDI-‐TOF proﬁes have been created for economically important .cks of livestock in Africa. Field .ck species correctly iden.ﬁed in a ‘proof of concept’ experiment. Large scale .ck collec.ons should be carried out covering various geographic areas within Africa and the data used to update .ck distribu.on maps.
