A descriptive analysis of the potential association between migration patterns of bean and white-fronted geese and the occurrence of Newcastle disease outbreaks in domestic birds.

The sightings and migration patterns of 65 bean (Anser fabalis) and 65 white-fronted geese (Anser albifrons) are reported. In the past, these geese were serologically screened for the occurrence of Newcastle disease virus (NDV) and other avian viral diseases by Hlinak et al. (3).

Characterisation of pseudorabies virus isolated from wild boar (Sus scrofa).

Seroepidemiological evidence had suggested that pseudorabies (Aujeszky's disease) virus (PrV) infections occur in the European wild boar population in eastern Germany, although attempts to isolate the causative agent had failed. In 1995 and 1996, five virus isolates were recovered from latently infected wild boar originating from two regions where the disease was endemic. The isolates were identified as PrV by immunofluorescence and neutralisation with specific sera and grouped as PrV type I.

[Occurrence of paramyxovirus 1 (PMV 1) infections in pigeons].

From 1992 to 1997 the occurrence of the paramyxovirus-1 infection in pigeons in the region of Berlin-Brandenburg was examined. Using the haemagglutination inhibition test the presence of PMV 1/NDV could be demonstrated indirectly. There was a rather high percentage (19.

Serological survey of viral pathogens in bean and white-fronted geese from Germany.

Sera from wild geese were tested for antibodies to selected viral pathogens at a resting site for wild waterfowl in Germany. Serum samples from both bean geese (Anser fabalis) and white-fronted geese (Anser albifrons) collected in October 1991 were examined using serological methods licensed for routine diagnosis in domestic poultry. Of 130 sera tested, antibodies to several infectious agents were found including Newcastle disease virus (45%), goose parvovirus (48%), avian reovirus (29%), and avian adenovirus or egg drop syndrome 76 virus (6%).

Pseudorabies in the European wild boar from eastern Germany.

Sera collected from European wild boar (Sus scrofa) shot in Eastern Germany between January 1991 and December 1994 were tested for antibodies to pseudorabies virus (PRV). Of 3,143 sera tested, 281 (8.9%) and 13 (0.
