Avian influenza A viruses isolated from (A) the Tanguar haor and (B) live poultry markets (LPMs) of Bangladesh. (A) In February 2015, December 2015 and February 2016, 120, 1000, and 1011 samples, respectively, were collected from ducks (Khaki Campbell) from free-range farms and wild birds in the Tanguar haor area. No viruses were isolated from the samples collected in February 2016. All viruses were isolated from ducks, except one H7N5 virus, which was isolated from a wild black-tailed godwit. (B) Monthly virus isolation from LPMs in Bangladesh. From February 2015 through February 2016, 160 samples (95, 95 and 93 samples were collected in February, March and April 2015, respectively) were collected per month from five LPMs in Bangladesh. Samples collected in May, October and November 2015 did not result in any virus isolates. (C) Viruses isolated from various species of birds in LPMs. Only 18 samples were collected from geese (April 2015) during the surveillance period, from which one H5N1 virus was isolated. Virus isolation rates (× 100 number of viruses isolated/number of samples inoculated in eggs) are shown on top of each column representing different species.
