Angiostrongylus dujardini infection in a coconut lorikeet (Trichoglossus haematodus) from a zoological garden in Switzerland.

Angiostrongylus spp. (Metastrongyloidea) can cause severe disease in several animal species and humans. This report describes an infection with Angiostrongylus dujardini in a captive coconut lorikeet (Trichoglossus haematodus) from a zoo in Switzerland.

Avian haemosporidian parasites in captive and free-ranging, wild birds from zoological institutions in Switzerland: Molecular characterization and clinical importance.

Avian haemosporidian parasites are widespread and infect birds from a broad variety of avian families with diverse consequences ranging from subclinical infections to severe and fatal disease. This study aimed to determine the occurrence and diversity of avian haemosporidia including associated clinical signs and pathomorphological lesions in captive and free-ranging, wild birds from two zoos and the near environment in Switzerland. Blood samples from 475 birds, including 230 captive and 245 free-ranging, wild individuals belonging to 42 different avian species from 15 orders were examined for the presence of avian haemosporidian DNA by a one-step multiplex PCR designed to simultaneously detect and discriminate the genera , and by targeting mitochondrial genome sequences.

Single-inlet univentricular heart with persistent truncus arteriosus in a Sumatran orangutan (Pongo abelii).

Univentricular heart malformations are rarely described in the veterinary literature. This case report describes a single-inlet univentricular heart with persistent truncus arteriosus as a cause of death of a captive-bred, 2-day-old, female Sumatran orangutan (Pongo abelii), a critically endangered species.

in free-ranging white stork () nestlings in Switzerland.

Syngamosis is a disease caused by the strongylid nematode which infects the respiratory tract of various bird species around the world. The parasite appears to be harmful for a wide variety of avian orders, occasionally leading to a fatal outcome, particularly in young birds. The aim of this study was to examine the parasitic fauna in deceased or euthanized, free-ranging white storks nesting at the Zoo Basel in 2019 and 2020; and to assess the extent to which these parasites contributed to the wild birds' death.

Fatal avian malaria in captive Atlantic puffins () in Switzerland.

Avian malaria is a vector-borne disease caused by species which may affect a broad spectrum of bird families worldwide. In most endemic and migratory birds, infections seem not to cause severe harm; however, non-indigenous species kept in human care such as penguins may experience high morbidity and mortality rates. Fatal avian malaria may also occur in other non-native seabirds such as puffins ( spp.
