Avian influenza (AI) is a zoonotic viral endemic disease that affects poultry, swine, and mammals, including humans. Highly pathogenic avian influenza (HPAI) is caused by influenza type A virus subtypes H5, and H7 which are naturally carried by a wild bird and often affect domestic poultry. Avian influenza (AI) is a major problem worldwide that causes significant economic losses in the poultry sector. Since 2003, the widespread H5N1 HPAI in poultry has led to high mortalities resulting in huge economic losses in the poultry sector in Indonesia. Domestic poultry is a key source of income that contributes to economic growth, both directly and indirectly, by reducing poverty among the people living in rural communities. Furthermore, in many developing countries, including Indonesia, rural people meet a portion of their food needs through backyard poultry. Nevertheless, this sector is strongly affected by biosecurity hazards, particularly in Indonesia by HPAI infections. Avian influenza (AI), subtype H5N1 has zoonotic significance, posing major risks to public health and poultry. Due to close interaction between wild migratory birds and ducks, the domestic poultry sector in Indonesia is directly affected by this virus. This virus continues to be ubiquitous in Indonesia as a result of the unpredictable mutations produced by antigenic drift and shift, which can persist from a few days to several years. In this review, the epidemiology and impact, of highly pathogenic avian influenza H5N1 subtype virus infection on backyard poultry in Indonesia were discussed.

“…Leekaew et al (2008) In this study, ducks (Anseriformes) might determine the role of waterfowl as a natural reservoir for avian influenza (AI) virus. Susanti, Soejoedono, Mahardika and Wibawan (2008a) state that waterfowl is allegedly act as a natural reservoir for avian influenza (AI) virus subtype H5N1, as evidenced by the high prevalence of H5N1 infection in the unvaccinated healthy waterfowl. Waterfowl has reported to have no experience in pain, paralysis and death even though they are infected with AI virus subtype H5N1 which is shown to be molecularly and biologically pathogenic (Susanti, Soejoedono, Mahardika, & Wibawan, 2008b).…”

ABSTRACT. This study was realized to determine the genetic variation of Central Javanese duck based on the D-Loop mtDNA gene. D-loop gene was amplified using PCR technique by specific primer and sequenced using dideoxy termination method with ABI automatic sequencer. ClustalW from MEGA-6.06 software program was employed for multiple alignments of nucleotide sequences. Nucleotide sequences of D-loop gene of mtDMA from the Central Javanese duck were aligned together with other Anas isolates from Genbank using ClustalW of MEGA-6.06 program. The estimation of genetic distance and phylogenetic tree construction were analyzed by Neighbor-Joining method, whereas the calculation of distance matrix was performed using Kimura 2-parameter. Multiple alignments obtained were 720 nucleotides at position 56 to 779 at the 5 'end. The results of the polymorphism analysis on D-loop sequences produced 23 haplotypes. However, this haplotype information does not represent the relationship among the geographical origins of duck with the certain duck species name. Moreover, a total number of 32 variable sites were identified. Insertions were detected in four sequences (126, 155, 771 and 779 nucleotide number). In the phylogenetic analysis, it is safe to conclude that the Central Javanese duck is closely related to Anas platyrhynchos and Anas zonorynchos.
