Dirofilaria repens and Dirofilaria immitis DNA findings in mosquitoes in Germany : temperature data allow autochtonous extrinsic development / R. Sassnau, C. Czajka, M. Kronefeld, D. Werner, C.

Abstract:
After the repeated demonstration of Dirofilaria repens infections in German dogs, D. repens and Dirofilaria immitis DNA was detected in mosquitoes trapped in 2011, 2012 and 2013 in northeastern and southwestern Germany within the framework of culicid monitoring projects. As temperature is the most important factor dictating the extrinsic development of dirofilarial larvae in the potential vector, data of the GermanWeather Service (DWD) were analysed for the
regions where the positive mosquitoes had been collected. Based on the mean daily temperatures recorded by weather stations most closely to the collection sites of the mosquitoes, it can be concluded that the mosquitoes were trapped in time periods that allowed for the completion of the developmental cycle of the worms in the mosquitoes and a subsequent transmission to a vertebrate host. The results of this study confirm the principal climatic suitability of certain German
regions for the establishment of natural dirofilarial transmission cycles. Moreover, the theoretical climatic considerations, together with findings of D. repens infections in German dogs.
