Avian Flu Scan for Feb 27, 2014
Avian flu strains in Egypt; H5N1 outbreaks in Cambodia, Nepal
Filed Under:
Avian Influenza (Bird Flu)
Study: 10% avian flu rate in Egyptian birds, H5N1-H9N2 co-infections
Active surveillance in Egypt found that 10% of all poultry samples from August 2010 through January 2013 tested positive for avian flu, and the H9N2 strain emerged in the country during that time and co-infected birds with H5N1, according to a report yesterday in Emerging Infectious Diseases.
A team of veterinarians collected cloacal (anus) and oropharyngeal (beak) swab samples from 11,452 birds from commercial farms, backyard flocks, live-bird markets, and abattoirs. The teams also collected samples from sick or dead birds at the sites.
Of the samples, 84.2% were from chickens, 10.3% from ducks, and 5.5% from other domestic bird species.
Polymerase chain reaction tests were positive for 1,144 birds (10%), with the percentage by governorate ranging from 3% in Menoufia to 18% in Dakahlia.
The authors, from Egypt and the United States, also noted their first detection of H9N2 virus in Egyptian poultry in December 2011 and the first H5N1-H9N2 co-infections in March 2012. They detected 151 such co-infections during the study period.
The authors advocate for continued avian flu surveillance and conclude, "Cocirculation of different subtypes poses concern for potential reassortment."
Feb 26 Emerg Infect Dis report
Cambodia, Nepal report H5N1 outbreaks in poultry
Highly pathogenic H5N1 avian flu has struck small flocks in Cambodia and Nepal recently, affecting 2,700 poultry, according to separate reports posted yesterday by the World Organization for Animal Health (OIE).
In Cambodia, H5N1 killed 210 birds in a village flock of 450 in Kampong Speu province, and the remaining 240 poultry were culled to prevent disease spread. And in adjoining Kandal province, the virus killed 200 of 250 birds, with the remainder of the village flock culled.
The provinces are in southern Cambodia, near the capital of Phnom Penh. Kandal abuts Vietnam on the province's southern border. The larger outbreak began Feb 18 and the other a day later. Both were resolved on Feb 25.
Feb 26 OIE report on Cambodia
In Nepal, H5N1 killed 570 of 2,000 poultry on a layer farm in Koshi province in the eastern part of the country, not far from its border with India. The remaining birds were culled to contain the outbreak.
Beginning Feb 13, the birds showed signs of depression, decreased egg production, respiratory distress, and paralysis before they died, the OIE report said. The farm is being disinfected, and officials have restricted movement of poultry in the area.
Both countries have experienced numerous recent H5N1 outbreaks in domestic birds, as has Vietnam.
