A qualitative study on knowledge, attitude, and practice (KAP) toward swine influenza, information on pig farms and zoonosis reporting systems in Thailand.

This qualitative study aimed to determine knowledge, attitudes, and practices (KAP) on swine influenza (SIV) among pig farm owners, pig farm workers, community leaders, public health personnel, and villagers who lived nearby pig farms in the northeastern (Nakhon Ratchasima), northern (Chiang Mai), and central (Nakhon Pathom) provinces of Thailand during May to December 2022. The qualitative information was collected from 91 respondents, including 33 individuals who participated in key informant interviews (KIIs) and 58 individuals who joined ten focus group discussions (FGDs) (5-7 persons per FGD). Our results showed that pig farmers, farm workers, and villagers lacked SIV-related knowledge and did not employ preventive measures.

Patterns of duck Tembusu virus infection in ducks, Thailand: a serological study.

Duck Tembusu virus (DTMUV), a mosquito-borne flavivirus, has been identified as a causative agent of an emerging viral disease in ducks, causing significant economic losses to the duck-producing industry. In Thailand, DTMUV has been detected sporadically in ducks since the first report in 2013. However, information on the patterns of DTMUV infection in ducks in Thailand is limited.

Persistence of pdm2009-H1N1 internal genes of swine influenza in pigs, Thailand.

Swine influenza is one of the important zoonotic diseases of pigs. We conducted a longitudinal survey of swine influenza A viruses (S-IAV) circulating in a pig farm with history of endemic S-IAV infection from 2017 to 2018. The samples were collected from 436 pigs including nasal swab samples (n = 436) and blood samples (n = 436).

Evaluation of host systems for efficient isolation and propagation of duck Tembusu virus.

Several phylogenetic clusters of duck Tembusu virus (DTMUV) that caused outbreaks in ducks in Asia have been identified since its emergence in 2010, highlighting the need for an efficient host system that can support isolation of all circulating phylogenetic clusters of DTMUV. In this study, various host systems, including different avian embryonated eggs (duck and chicken) and cell cultures (primary duck embryo fibroblast (DEF), primary chicken embryo fibroblast (CEF), baby hamster kidney (BHK-21), African green monkey kidney (Vero) and clone C6/36 (C6/36) cells), were evaluated and compared for their ability to support DTMUV isolation and propagation. Our results showed that all host systems were susceptible to DTMUV infection; however, BHK-21 and primary DEF cells supported more efficient replication of DTMUV compared to the other host systems.
