To determine the genetic origins of novel H3 avian influenza viruses of chickens and ducks in Korea, genetic characterization of H3 avian influenza viruses isolated from live poultry markets and migratory aquatic birds in South Korea during 2004–2006 was conducted. Phylogenetic analysis revealed that at least four novel genotypes of H3N2 and two genotypes of H3N6 avian influenza viruses were co-circulating in backyard poultry of Korea. The viruses were reassortants between H9N2 viruses of Korean chickens and unknown influenza viruses of migratory birds. Genetic comparison of H3 viruses from live bird markets with those from wild bird isolates revealed that certain gene segments of wild bird isolates are related closely to those of Korean group H9N2 viruses isolated from live poultry markets in 2003. Furthermore, animal-challenge studies demonstrated that the pathogenicity of certain avian H3 influenza viruses was altered due to reassortment, leading to H3 avian influenza viruses in Korea that can potentially expand their host range to include mammals. These studies emphasize the continuing need to monitor backyard poultry at live poultry markets to better understand interspecies transmission and the emergence of novel influenza viruses that have the potential to infect humans.

In order to analyze the spread of avian influenza A (H7N9), we construct an avian influenza transmission model from poultry (including poultry farm, backyard poultry farm, live-poultry wholesale market, and wet market) to human according to poultry transport network. We obtain the threshold value for the prevalence of avian influenza A (H7N9) and also give the existence and number of the boundary equilibria and endemic equilibria in different conditions. We can see that poultry transport network plays an important role in controlling avian influenza A (H7N9). Finally, numerical simulations are presented to illustrate the effects of poultry in different places on avian influenza. In order to reduce human infections in China, our results suggest that closing the retail live-poultry market or preventing the poultry of backyard poultry farm into the live-poultry market is feasible in a suitable condition.

Newcastle disease (ND) is a serious disease of poultry that causes significant economic losses. Despite rampant ND outbreaks that occur annually in Kenya, the information about the NDV circulating in Kenya is still scarce. We report the first countrywide study of NDV in Kenya. Our study is aimed at evaluating the genetic characteristics of Newcastle disease viruses obtained from backyard poultry in farms and live bird markets in different regions of Kenya. We sequenced and analyzed fusion (F) protein gene, including the cleavage site, of the obtained viruses. We aligned and compared study sequences with representative NDV of different genotypes from GenBank. The fusion protein cleavage site of all the study sequences had the motif 112RRQKRFV118 indicating their velogenic nature. Phylogenetic analysis revealed that the NDV from various sites in Kenya was highly similar genetically and that it clustered together with NDV of genotype V. The study samples were 96% similar to previous Ugandan and Kenyan viruses grouped in subgenotype Vd This study points to possible circulation of NDV of similar genetic characteristics between backyard poultry farms and live bird markets in Kenya. The study also suggests the possible spread of velogenic NDV between Kenya and Uganda possibly through cross-border live bird trade. Our study provides baseline information on the genetic characteristics of NDV circulating in the Kenyan poultry population. This highlights the need for the ND control programmes to place more stringent measures on cross-border trade of live bird markets and poultry products to prevent the introduction of new strains of NDV that would otherwise be more difficult to control.

Poultry Farming

Backyard chicken farming is as an effective tool for poverty reduction in rural areas, by providing living to resource poor communities; it is an important source of extra cash income other than eggs and meat for family consumption. The present study was carried out to assess the role of backyard poultry farming in supplementing household economy of rural farmers dwelling in district Quetta, Pakistan. Information from ninety-nine randomly selected female backyard poultry farmers were gathered during November 2016 to March 2017. Owing to previous government and non-government interventions backyard poultry keeping was found as an established practice. Women were found the main custodian of backyard poultry birds and consequently were the main beneficiary of the activity. Poultry birds of Fayoumi and Golden / Rhode Island Red (RIR) breeds were the main types. Majority of the farmers reared these birds under scavenging conditions in combination with feeding on household left over dry bread (52%); most of the respondents (62%) were taking care of the birds by themselves which resulted in overall low production cost. Income included the earning received from sale of birds, eggs and the home consumption of poultry meat and eggs. Net income per annum per household was estimated as Pakistani Rupee (PKR) 79290/- (US$ 566). The estimated Rank Based Quotients (R.B.Q) based on farmers perception disclosed backyard poultry keeping as an important domestic source of meat and eggs with almost no or very little capital investment, ranked (I, 80%) followed by a substantial source of supplementary income and was ranked (II, 79%). Amongst the problems, disease outbreaks were the most prevailing problem (I, 90%) followed by unavailability of vaccines (II, 85%). The backyard poultry farming generated subsistence income and provided high quality valuable food that improved household nutrition.
