The interplay of biotic and abiotic factors driving Ixodes ricinus abundance trends are not fully understood. Machine learning (ML) approaches being increasingly used to explore this predict future patterns species, however, the studies focusing on date have had limitations (including short study duration, limited sample size, narrow geographical range use a single ML model). This was undertaken address these by applying 11 predictive models (across three data clustering techniques) large I. occurrence dataset (27,150 records) containing temporal from 20-year period across 30 European countries, coupled with covering climatic habitat features (temperature, rainfall, Normalised Difference Vegetation Index (NDVI), percentage discontinuous urban fabric land category). To assess which model most suited prediction abundance, four performance metric values were calculated per model: Root Mean Square Error (NRMSE), Scatter (SI), Absolute Percentage (MAPE) R2, all describe statistical relationship between predicted actual values. Furthermore, using Random Forest (RF) methods, we determined significantly impacted upon abundance. demonstrated that Agglomerative Hierarchical Clustering (AC) methods Linear Regression (LR) modelling performed best dataset. Our findings revealed rainfall primary contributors temperature playing lesser role. measured according extent error increase following exclusion factor analysis. We provide summary strongly linked can be guide interventions aid control ticks tick-borne disease Europe.

Tick-borne pathogen epidemiology involves vectors, in Europe mainly Ixodes ricinus, and vertebrate hosts. Ruminants are reservoirs for Anaplasma phagocytophilum, but not Borrelia burgdorferi sensu lato (s.l.), possibly clearing the infection from ticks. However, such clearance is epidemiologically relevant nymphal Of 1874 ticks collected wildlife present study, 1535 spp. (796 nymphs, 739 females) were tested by qPCR, with a proportion of 26.3% (nymphs: 24.5%, females: 28.3%) positive 87.4% A. phagocytophilum 62.8%, 92.4%). In female deer (N = 720), nymphs 785), frequency declined significantly increasing engorgement duration as inferred coxal index. differentiation revealed B. s.l. nine miyamotoi one ten successfully analysed having engorged <48 hours, only three s.l.- vs. six miyamotoi-positive coinfected tick among longer engorgement. copy numbers showed U-shaped relationship duration.

The results imply that on cervids may reduce prevalence presumably due to low overall blood volume ingested, insufficient this stage.

This study applied participatory citizen science across Spain Portugal to gather public perspectives on the impact tick bites, presence TBDs potential connection α-Gal syndrome (AGS). Data collected from questionnaire (380 participants) was geographically represented using QGIS Geographic Information System fitted into multiple generalized linear models (GLMs). Statistical analysis identified factors influencing occurrence local skin reactions post-tick bite, AGS-compatible symptoms visits health centers following exposure.
