() is considered as an opportunistic zoonotic pathogen that may cause gastroenteritis in humans and other animals. Wild birds may be as potential vectors of around urban and suburban areas. Here, 520 samples were collected from 33 wild bird species in urban and suburban areas, Beijing. In total 57 were isolated from seven species. It was found that Nineteen (33.33%, 19/57) isolates were resistant to at least one of 11 antibiotics, especially streptomycin (36.84%) and four isolates resistant to all. Nineteen (33.33%, 19/57) isolates were multi-drug resistance. Multilocus sequence typing (MLST) analysis of the isolates showed that 36 different sequence types (STs) belonged to four Clonal complexes and unassigned. Twenty STs (55.56%) and six alleles among them were first detected. Virulence genes including , , and the cytolethal distending toxin (CDT) gene cluster, were detected in all isolates, but truncated gene clusters only detected in the isolates from the crow, daurian jackdaw and silver pheasant. In conclusion, it was the first detection of involved truncated gene clusters from the silver pheasant. These wild birds around urban and suburban areas may pose potential public health problems as reservoir vectors of .

Parasitic survey of birds of prey used for falconry in Poland.

Birds of prey raised in captivity have direct contact with the environment and are fed raw meat various animals, which increases the risk of infections caused by parasites, including endoparasites. The aim of this study was to evaluate the prevalence of endoparasites in predatory birds of the orders Accipitriformes and Falconiformes that are used in falconry in Poland. Fresh feces were sampled from 52 birds, including 16 saker falcons (Falco cherrug), 8 lanner falcons (Falco biarmicus), 7 peregrine falcons (Falco peregrinus), 8 Harris's hawks (Parabuteo unicinctus), 7 Eurasian goshawks (Accipiter gentilis), 3 common kestrels (Falco tinnunculus), 1 Eurasian sparrowhawk (Accipiter nisus), 1 red-tailed hawk (Buteo jamaicensis), and 1 common buzzard (Buteo buteo).

Background: The Japanese quail () is a small migratory bird whose main habitats are located in East Asia, Russia, China, Japan, Korea, and India. The Japanese quail was first introduced into the Iraqi research sector in the early 1980s. This investigation aimed to identify the genetic divergence between the available genetic lines of the Japanese quail in Iraq as a first step to conducting further conservation and breeding, benefiting from studying the genetic diversity related to productivity, adaptation, and immune susceptibility.

Origin, spread, and interspecies transmission of a dominant genotype of BJ/94 lineage H9N2 avian influenza viruses with increased threat.

Virus Evol

National Key Laboratory of Veterinary Public Health and Safety, Key Laboratory for Prevention and Control of Avian Influenza and Other Major Poultry Diseases, Ministry of Agriculture and Rural Affairs, College of Veterinary Medicine, China Agricultural University, 2 Yuanmingyuan West Road, Haidian District, Beijing 100193, China.

The H9N2 subtype of avian influenza viruses (AIVs) is widely prevalent in poultry and wild birds globally, with occasional transmission to humans. In comparison to other H9N2 lineages, the BJ/94 lineage has raised more public health concerns; however, its evolutionary dynamics and transmission patterns remain poorly understood. In this study, we demonstrate that over three decades (1994-2023), BJ/94 lineage has undergone substantial expansion in its geographical distribution, interspecies transmission, and viral reassortment with other AIV subtypes, increasing associated public health risks.

The superfamily Ascaridoidea are parasitic nematodes in vertebrates, including birds and humans. In order to investigate the presence and distribution of these parasitic nematodes in birds acting as the definitive host, 157 birds of 64 bird species belonging to 16 orders were collected and necropsied in the Kızılırmak Delta area in the Bafra district of Samsun province. The parasites collected were fixed in 70% ethyl alcohol and identified under a light microscope, and morphologically important regions were photographed for identification.

Researchers have identified Avastrovirus as a significant genus of bird viruses, linked to various avian diseases such as enteritis, growth retardation, nephritis and hepatitis. These infections can cause substantial economic losses in agrocultureand have a widespread impact on global food production. Although there have been numerous studies on these viruses, most of them-mainly focuses on poultry.
