Abstract

Pigs have an important role in the ecology of influenza virus since they are sensitive to influenza viruses from human and avian origin. Influenza A virus has a host specificity, although not absolute, so most of the AI virus circulating in various species is only limited to the species, but sometimes there are interactions between different AI virus species or strain. Farming systems that combine a variety of animal species together in the same or around the sites have an important role in the spread of disease and transmission between species. This study is aimed to investigate the cycle of AI virus in order to determine the potential occurrence of viral transmission among species pig and bird at the pig farm that also raising poultry. Influenza virus was identified by methods of RT-PCR and qRT-PCR. The results showed that the novel H1N1 pandemic virus was detected in one pig farm in Tangerang (Banten Province). The AI/H5 virus is also detected in the pig farm that also raises poultry or poultry/pig farmers and located adjacent each other. The AI virus / influence A is also detected in most of the pigs. Detection of AI viruses that infected in pig farm which kept birds or poultry farm around the pigs farm had potential of AI virus transmission from birds species to pig or vise versa. The pigs could serve as a mixing vessel, thus providing opportunities likelihood of reassortant viruses.

Abstract

Avian influenza virus subtype H5N1 outbreak has become endemic in Indonesia since 2003. The disease does not only cause immense economic losses but it also leads to significant fatality of human being. The existence of traditional markets including live bird trading is suspected to play important role in the spreading and evolution of the virus. The objective of this study was to identify the circulation of H5N1 virus at traditional markets of East Java in 2012 by using reverse transcriptase polymerase chain reaction (RT-PCR) test and virus isolation. As results, this study detected the presence of the H5N1 virus circulating in Gresik, Mojokerto, Lamongan and Surabaya in both of live birds and environmental samples. The successfulness of virus isolation indicated a potential transmission to other hosts, including to human. This study suggests that the improvement of the poultry trading system at traditional markets by implementing sanitation, hygiene and biosecurity is necessary to reduce the burden of virus contamination at the market environment.
