We reviewed pathological findings and to a lesser extent epidemiological data from 70 free-ranging columbiforms naturally infected with Pigeon paramyxovirus-1 (PPMV-1) from 25 different PPMV-1 mortality events in columbiforms in the USA. In a subset of 17 birds from 10 of the studied outbreaks, we carried out immunohistochemistry targeting PPMV-1 nucleoprotein to determine the tissue distribution of the virus.

Data set pertaining to avian paramyxovirus (APMV-1) sequences used in phylogenetic analyses. Data contains GenBank Accession numbers, host species common name and taxonomic order, collection year, and collection location.

This data set consists of two tables associated with a study of Haemosporidian parasite infection in Northwestern Crows (Corvus caurinus) sampled at six locations throughout southcentral and southeast Alaska in 2007-2008. The first table contains species, location, banding, and morphometric data for all samples. The second table contains results from heamosporidian parasite screening of crow blood samples using molecular techniques. Genomic DNA was extracted from blood samples and screened for the presence of Haemoproteus, Plasmodium, and Leucocytozoon blood parasites using a nested-PCR method. Parasite genetic data is provided as GenBank accession numbers for any samples that tested positive for haemosporidian infection

This dataset includes one table of blood parasite (hematozoa) infection data from 197 Emperor Geese (Anser canagicus) and 110 Cackling Geese (Branta hutchinsii minima) sampled on the Yukon-Kuskokwim Delta, Alaska, in 1998 and 2014. Three genera of blood parasites (Leucocytozoon, Haemoproteus, Plasmodium) were detected by molecular sequencing of a 479 bp fragment of the Cytochrome-b gene. The table provides age, sex, infection status, and NCBI GenBank accession numbers of the DNA sequences obtained from infected samples.

Only one virus, Avipox, has been documented in wild birds in Hawaii. Here, using immunohistochemistry and PCR, we found that two native threatened Hawaiian geese, one with multicentric histiocytoma and another with toxoplasmosis and one Laysan albatross with avian pox were infected with reticuloendotheliosis virus (REV). The virus was isolated from one of the geese by cell culture. PCR surveys of other Hawaiian geese with various pathologies, avian pox cases, and pox viral isolates failed to reveal REV suggesting the virus is uncommon, at least in samples examined. The full genome of the Gag, Pol, and Env genes were sequenced for all three infected birds and revealed geographic divergence of the Pol gene suggesting it to be under strong selective pressure. Our finding of REV in Hawaii makes this only the second virus documented in native Hawaiian birds associated with pathology. Moreover, the presence of REV in a pelagic seabird is unusual. Future surveys should seek the reservoir of the virus in efforts to trace its origins.

The purpose of this project is to determine the infectious status and exposure status of several diseases that have the potential to impact the health of greater sage grouse (Centrocercus urophasianus) captured in Montana, USA to be translocated to Alberta, Canada. Specific disease status to be tested include, infection with avian influenza virus (AIV), infection with Avian Paramyxovirus-1 (APMV1) causative agent of Newcastle disease virus, and exposure to West Nile Virus (WNV) via serology to detect antibodies to WNV.
