The Department of Livestock Development would like to inform that no highly
pathogenic avian influenza virus or bird flu has been diagnosed in Thailand.
However, there might have been some confusion with an outbreak [in]
mid-November 2003, of mixed infection of fowl cholera (_Pasteurella
multocida_ type A) and acute pasteurellosis (_Pasteurella haemolytica_) in
one layer farm [of] about 68 000 birds at Nong Bua district in Nakorn Sawan
The birds were separated in 15 houses by age groups from 12-86 weeks. There
were 7100 layers aged 86 weeks in one house where 5000 birds died from
among 5500 affected hens.
These birds were due to be removed within the next few weeks. The last
vaccination against fowl cholera was more than 5 months ago, and native
chicken might be a source of infection.
A stamping-out measure was employed; that the farm was depopulated,
cleansed, and disinfected. The outbreak was completely contained. The area
was under close surveillance for 30 days (until 22 Dec 2003).
Controls on animal movement were in force within 60 kilometers; there is
also a ban on exportation of poultry produced in this area until 31 Mar
2004 in order to meet the health requirements of Thailand's poultry trade
This information appeared in an alert message on the OIE website on 20 Dec
[ProMED-mail would like to thank the Department of Livestock Development in
Thailand for clarifying the situation. For a background discussion on avian
cholera, see the Moderator comment on the recent ProMED-mail posting Avian
