Influenza A virus infections in land birds, People's Republic of China.

Peterson AT, Bush SE, Spackman E, Swayne DE, Ip HS - Emerging Infect. Dis. (2008)

Bottom Line: Water birds are considered the reservoir for avian influenza viruses.We examined this assumption by sampling and real-time reverse transcription-PCR testing of 939 Asian land birds of 153 species.Influenza A infection was found, particularly among migratory species.

ABSTRACT
Water birds are considered the reservoir for avian influenza viruses. We examined this assumption by sampling and real-time reverse transcription-PCR testing of 939 Asian land birds of 153 species. Influenza A infection was found, particularly among migratory species. Surveillance programs for monitoring spread of these viruses need to be redesigned.

Southeastern Asia, showing 5 sites in the People’s Republic of China where land birds were collected and tested for influenza A virus. Prevalence values were 4% (n = 103) in Dashahe in 2006; 6% (n = 194) in Kuan Kuoshui in 2006; 0.3% (n = 328) in Shuipu in 2007; 3% (n = 184) in Jing Xi, in 2004; and 0% (n = 130) in Shiwandashan in 2005.

Figure 1: Southeastern Asia, showing 5 sites in the People’s Republic of China where land birds were collected and tested for influenza A virus. Prevalence values were 4% (n = 103) in Dashahe in 2006; 6% (n = 194) in Kuan Kuoshui in 2006; 0.3% (n = 328) in Shuipu in 2007; 3% (n = 184) in Jing Xi, in 2004; and 0% (n = 130) in Shiwandashan in 2005.

Mentions: During 2004–2007, as part of a broader biodiversity survey and inventory program, we sampled birds from mostly forested sites in Guangxi and Guizhou Provinces in the southern part of the People’s Republic of China (Figure). Sampling was conducted by mist netting and selective harvesting with shotguns; all birds in the study were apparently healthy and behaving normally at the time of collection. Because initial sampling was focused on endoparasite communities, samples from 2004–2005 consisted of complete gastrointestinal tracts frozen in liquid nitrogen. In 2006–2007, sampling was conducted specifically for viruses. Cloacal swabs were collected in 2006 and buccal–cloacal swabs were collected in 2007. All swabs were preserved in 95% ethanol.
