Background Tick infestations severely impair cattle health and productivity in Nigeria through blood loss, hide damage, and transmission of tick-borne pathogens. Objective This study assessed key risk factors influencing tick infestation and evaluated control methods among Fulani pastoral herds in Plateau State. Methods A cross-sectional survey involving 250 cattle from ten herds was conducted across five Local Government Areas. Tick burden was analyzed against acaricide application methods (pour-on vs. hand-spray), hand-picking frequency, and herd mobility (sedentary vs. migratory). Data were collected via owner interviews and manual tick counts. Statistical analyses were performed using generalized linear models in R software. Results Cattle treated with pour-on acaricides had significantly lower tick burdens compared to those treated via hand-spray (P<0.05). Herds that practiced hand-picking five times weekly had fewer ticks than those hand-picking thrice weekly (P<0.01). Migratory herds recorded significantly lower infestations than sedentary herds (P<0.05). Conclusion Effective tick control requires the integration of optimized acaricide application, frequent manual removaland consideration of herd mobility patterns. Education, capacity building, and policy support are necessary to enhance adoption of effective tick control measures among pastoralists.

Studies have linked freshwater snails with human flukes as a result of repeated contacts with contaminated water. This study is aimed to determine the distribution of freshwater snails and their infectivity rates along human dwellings in Okigwe Imo state using Physico-Chemical parameters. Freshwater snails were collected by using long plastic spoons and with hand-picking method. The Physico-Chemical parameters were determined with appropriate instrument and freshwater snails harvested from the site were morphologically identified. One thousand four hundred and nine (1409) freshwater snails belonging to the species Lymneae and Bulinus were collected once a week throughout the period of study with the relative percentage of 43.9%; 29.9% ;26.2% respectively. The infectivity rate was highest in snails that were collected in the month of May compared to those collected in June and July, the rate was 69.2%, 50.1% and 33.6% in the months of May, June and July respectively. Dissolved oxygen (DO), Biological oxygen demand (BOD) and PH were found to significantly influence snail distribution in the site (p<0.05). The finding showed that 54.2% of all the snails collected were infected. The snail distribution observed may give an insight into some aspects of the epidemiology of trematodes infection in Okigwe the site for the study and their potential risks to infect human beings and animals.
