Overview of avian influenza virus in urban feral pigeons in Bangkok, Thailand.
Epidemiological investigations on the role of clinically healthy racing pigeons as a reservoir for avian paramyxovirus-1 and avian influenza virus
The results suggest that the examined racing pigeons may have had contact with AIV, but virus replication may have been too low to induce detectable circulating antibody levels, highlighting the relevance of APMV-1 vaccination and indicating the importance of flock immunity.
Investigation of Avian Influenza Viruses (H9N2-H5nx) in Pigeons during Highly Pathogenic Avian Influenza Outbreaks in Iran, in 2016.
Results of the tests performed on the swab and tissue samples were negative for H5 nor H9N2 viruses, and the Newcastle disease virus was isolated in most of the samples taken from dead pigeons, after inoculation in embryonated chicken eggs.

Avian Influenza A (H7N9) Virus in a Wild Land Bird in Central China, Late 2015
Genetic analysis showed that the virus was highly similar to the H7N9 viruses that circulated in poultry in other provinces in 2014, suggesting that virus transmission might have occurred between these two regions.

Susceptibility of herons (family: Ardeidae) to clade H5N1 subtype high pathogenicity avian influenza virus
It is demonstrated that most Ardeidae species are susceptible to H5 HPAIVs, sometimes with lethal effects, and the risks of cluster infection and contribution to viral dissemination should be continuously evaluated.
Epidemiology and Control of Avian Influenza H5N1 Virus in Thailand
Knowledge gained from this thesis emphasized that epidemiological analysis provides insight information of past epidemics which can be used for improving control measures and preventing the future epidemic of HPAI.
A Study of Risk Factors for Infection with HPAI H5N1 in Small Poultry Farms in Thailand Using a Questionnaire Survey
To fully understand the epidemiology of infection of small poultry farms with HPAI H5N1, control of movement of domestic poultry and serological and virological testing of the poultry population should be applied.
Global Avian In耀uenza Surveillance in Wild Birds: A Strategy to Capture Viral Diversity ONLINE REPORT
It is called for sustained, cost-effective investments in locations with high avian in�耀uenza diversity in wild birds and efforts to promote standardized sampling, testing, and reporting methods, including full-genome sequencing and sharing of isolates with the scienti-耀c community.


Molecular analysis of highly pathogenic avian influenza virus of subtype H5N1 isolated from wild birds and mammals in northern Germany.
Phylogenetic analyses of the HA and neuraminidase nucleotide sequences showed that avian influenza H5N1 isolates from the Astrakhan region located in southern Russia were the closest relatives and reassortment events could be excluded in comparison with other 'Qinghai-like' H 5N1 viruses.
Detection of Antibody to Avian Influenza A (H5N1) Virus in Human Serum by Using a Combination of Serologic Assays
A more sensitive microneutralization assay is developed to detect antibodies to avian influenza in humans and is being used for the seroepidemiologic investigations of the avian H5N1 influenza outbreak.
Wild bird surveillance from 2004 to 2007 in Thailand indicated that the prevalence of infection with avian influenza H5N1 virus in wild birds was low, but the annual prevalence varied considerably over this period, with a peak of 2.8% in 2007.
Molecular characterization of the complete genome of human influenza H5N1 virus isolates from Thailand.
The Thailand viruses contained more avian-specific residues than the 1997 Hong Kong H5N1 viruses, suggesting that the virus may have adapted to allow a more efficient spread in avian species.
Comparative Susceptibility of Selected Avian and Mammalian Species to a Hong Kong–Origin H5N1 High-Pathogenicity Avian Influenza Virus
It is demonstrated that the chicken/HK virus could infect multiple avian species, but also that the virulence of the chicken /HK virus varied significantly among avianspecies, including those species that are members of the same order.
The Surface Glycoproteins of H5 Influenza Viruses Isolated from Humans, Chickens, and Wild Aquatic Birds Have Distinguishable Properties
It is found that changes in both HA and NA may be required for the adaptation of influenza viruses from wild aquatic birds to domestic chickens and raises the possibility that chickens may be a possible intermediate host in zoonotic transmission.
New Strain of Influenza A Virus (H5N1), Thailand
The phylogenetic tree of the hemagglutinin (HA) gene showed that the Phichit samples were similar to the cluster of samples isolated during 2004 and 2005 in Thailand and Vietnam, and the Nakhon Phanom sample was clustered into the same group with viruses isolated from southeast People's Republic of China.
Highly pathogenic avian influenza.
Control programmes, which imply allowing a low incidence of infection, are not an acceptable method for managing HPAI, but have been used during some outbreaks of MPAI.
