Reconstruction of the molecular evolution of Usutu virus in Germany: Insights into virus emersion and circulation.

Usutu virus (USUV) is a mosquito-borne flavivirus that is widely distributed in southern and central Europe. The zoonotic virus circulates primarily between birds and mosquitoes, can, however, in rare cases infect other mammals including humans. In the past, USUV has been repeatedly associated with mass mortalities in birds, primarily blackbirds and owls.

Genotyping of isolates in healing process of bovine clinical mastitis.

In the present work, macrorestriction analysis was applied to characterize 44 field strains isolated from lactating cows suffering from mastitis in three dairy herds in Hesse State, Germany. Analysis of the obtained data by Pulse-Field Gel Electrophoresis (PFGE) showed that most of the isolates originating from different herds and cows were not related to each other. However, identical macrorestriction patterns were noted in 12 of 13 mastitic quarters in healing process, in three quarters even over the whole sampling period indicating persistent infection.

[Pathologic-anatomical changes in newborn goats caused by an intrauterine Schmallenberg virus infection].

A complex of various malformations in newborns was observed to an increased extent in sheep farms in the 2011/2012 lambing season. An intrauterine Schmallenberg virus (SBV) infection was identified as the cause of these malformations. To date, a detailed pathological description of the deformity complex has only been given for bovine and ovine newborns.

Use of competition ELISA for monitoring of West Nile virus infections in horses in Germany.

West Nile virus (WNV) is a mosquito-borne viral pathogen of global importance and is considered to be the most widespread flavivirus in the World. Horses, as dead-end hosts, can be infected by bridge mosquito vectors and undergo either subclinical infections or develop severe neurological diseases. The aim of this study was to detect WNV specific antibodies in horses in Germany as an indicator for an endemic circulation of WNV.

Detection and characterization of Histoplasma capsulatum in a German badger (Meles meles) by ITS sequencing and multilocus sequencing analysis.

A wild badger (Meles meles) with a severe nodular dermatitis was presented for post mortem examination. Numerous cutaneous granulomas with superficial ulceration were present especially on head, dorsum, and forearms were found at necropsy. Histopathological examination of the skin revealed a severe granulomatous dermatitis with abundant intralesional round to spherical yeast-like cells, 2-5 μm in diameter, altogether consistent with the clinical appearance of histoplasmosis farciminosi.
