Toxocara vitulorum infection in a yak (Bos mutus grunniens) calf from Tyrol (Austria).

The domestic yak Bos mutus grunniens is an important livestock animal in parts of Asia, especially of the Himalayan region, where people rely on it for meat, wool, milk and labour. In its countries of origin, the yak is commonly infected with the ascarid Toxocara vitulorum. This parasite mainly infects cattle (Bos taurus) and domestic buffalo (Bubalus bubalus) and is most commonly found in sub-tropical regions, but has been occasionally reported in more temperate climates, including several Central European countries.

Unnoticed arrival of two dipteran species in Austria: the synanthropic moth fly Clogmia albipunctata (Williston, 1893) and the parasitic bird louse fly Ornithoica turdi (Olivier in Latreille, 1811).

In the framework of a mosquito-monitoring program conducted from 2014 to 2018, non-culicid dipteran bycatch was identified to species-level with a focus on Diptera of medical and veterinary importance as part of a biodiversity initiative and barcoding project ("Austrian Barcode of Life"). Two species hitherto not known from Austria, the regularly sampled synanthropic moth fly Clogmia albipunctata (Psychodidae) and a single specimen of the louse fly Ornithoica turdi (Hippoboscidae), were collected in Vienna and Lower Austria. We confirmed identification results using a barcoding approach and provide the first reference sequence for O.

Monitoring of alien mosquitoes of the genus Aedes (Diptera: Culicidae) in Austria.

Systematic, continuous mosquito surveillance is considered the most reliable tool to predict the spread and establishment of alien mosquito species such as the Asian tiger mosquito (Aedes albopictus), Japanese bush mosquito (Aedes japonicus), and the transmission risk of mosquito-borne arboviruses to humans. Only single individuals of Ae. albopictus have been found in Austria so far.

Avian Plasmodium in Eastern Austrian mosquitoes.

Background: Insect vectors, namely mosquitoes (Diptera: Culicidae), are compulsory for malaria parasites (Plasmodium spp.) to complete their life cycle. Despite this, little is known about vector competence of different mosquito species for the transmission of avian malaria parasites.
