Predicting and mapping human risk of exposure to
2019
Background Tick-borne diseases have become increasingly common in recent decades and present a health problem in many parts of Europe. Control and prevention of these diseases require a better understanding of vector distribution. Aim Our aim was to create a model able to predict the distribution of Ixodes ricinus nymphs in southern Scandinavia and to assess how this relates to risk of human exposure. Methods We measured the presence of I. ricinus tick nymphs at 159 stratified random lowland forest and meadow sites in Denmark, Norway and Sweden by dragging 400 m transects from August to September 2016, representing a total distance of 63.6 km. Using climate and remote sensing environmental …
Spatial data of Ixodes ricinus instar abundance and nymph pathogen prevalence, Scandinavia, 2016-2017.
2020
ticks carry pathogens that can cause disease in both animals and humans, and there is a need to monitor the distribution and abundance of ticks and the pathogens they carry to pinpoint potential high risk areas for tick-borne disease transmission. In a joint Scandinavian study, we measured Ixodes ricinus instar abundance at 159 sites in southern Scandinavia in August-September, 2016, and collected 29,440 tick nymphs at 50 of these sites. We additionally measured abundance at 30 sites in August-September, 2017. We tested the 29,440 tick nymphs in pools of 10 in a Fluidigm real-time PCR chip to screen for 17 different tick-associated pathogens, 2 pathogen groups and 3 tick species. We present…
Patogēnu prevalence migrējošo putnu ērcēs 2018. gadā Papē
2022
Šajā pētījumā ir analizēta Borrelia spp., Babesia spp., Rickettsia spp., Anaplasma phagocytophilum un Ca. N. mikurensis prevalence 2018. gadā Papē ievāktās migrējošo putnu ērcēs. Izmantojot PCR metodes tika analizētas 788 Ixodes ricinus ērces, kas nolasītas no 369 putniem. Kur nepieciešams, patogēnus noteica līdz sugas līmenim, izmantojot sekvencēšanu. Tika konstatēts, ka minētie patogeni ir sastopami ar šādu prevelenci: Borrelia sp. – 7,86 %, Babesia sp. – 0,63 %, Rickettsia spp. – 11,41 %, A. phagocytophilum – 0,76 %, un Ca. N. mikurensis – 4,06 %. Proporcionāli visvairāk ērču bija Turdus ģints, Erithacus rubecula un Acrocephalus ģints putniem, kuru ligzdošanas un barošanās uzvedība veici…
