Lizards were caught by a noose attached pole or bare hands, identified species, examined for presence ticks. Each lizard then released at site capture. Ticks removed tweezers, species using keys, molecular tests performed pathogens. From 28 (17 specimens Z. 11 L. agilis) total 445 ticks, including 321 larvae 124 nymphs, as I. collected.

Vegetation changes in savanna ecosystems are playing an increasingly important role shaping tick populations and the spread of tick-borne diseases, with consequences for both wildlife livestock health. This study examines how factors such as climate variability, land use, vegetation structures, host availability influence survival, distribution, behavior. As grasslands degrade woody plants become more dominant, ticks finding suitable habitats, often supported by microclimatic conditions that favor their development. At same time, increased contact between domestic wild animals is facilitating transmission pathogens. review highlights seasonal patterns, fire regimes, grazing pressure, change driving shifts activity expanding geographical range. These increase risk disease humans alike. Addressing these challenges calls integrated management strategies include control, population monitoring, sustainable vector control methods. A holistic approach connects ecological, animal, human health perspectives essential effective prevention long-term ecosystem management.

Abstract The development of interventions targeting reservoirs Borrelia burgdorferi sensu stricto with acaricide to reduce the density infected ticks faces numerous challenges imposed by ecological and operational limits. In this study, pharmacokinetics, efficacy toxicology fluralaner were investigated in Mus musculus Peromyscus leucopus mice, main reservoir B . North America. Fluralaner showed rapid distribution elimination, leading fast plasma concentration (C p ) depletion first hours after administration followed a slow elimination rate for several weeks, resulting long terminal half-life. Efficacy fell below 100% while C (± standard deviation) decreased from 196 ± 54 119 62 ng/mL. These experimental results then used simulations treatment duration equivalent active period Ixodes scapularis larvae nymphs. Simulations that doses as low 10 mg/kg have potential protect P against infestation full I season if administered at least once every 7 days. This study shows investigating pharmacology candidate acaricides combination pharmacokinetic can provide important information support effective Lyme disease. It therefore represents critical step may help surpass limits inherent these interventions.
