The objective of this research was to analyze the overall performance, especially the removal efficiency, of the combined plug-flow anaerobic digester (PFAD) and upflow anaerobic sludge blanket (UASB) system, at a large swine farm in Thailand. Eighty-four wastewater samples from the digester were collected during the observation period of 302 days. Appropriate influent and effluent regions were selected for wastewater collection. Treatment efficiencies of the system were evaluated by key parameters such as chemical oxygen demand (COD), soluble chemical oxygen demand (SCOD), total solids (TS), total suspended solids (TSS) and total Kjeldahl nitrogen (TKN). In addition, microbiological parameters such as …

Canine influenza viruses (CIVs) have been reported in dogs worldwide. Due to the relatively high risk of influenza A virus (IAV) infections in dogs and humans through dog-human interface, the seroprevalence of IAVs in dogs in Thailand was surveyed. A serological survey of IAV infections in dogs in Thailand was conducted from December 2012 to November 2013 using ELISA assays for detecting anti-nucleoprotein (NP) antibodies (NP-ELISA) and hemagglutination inhibition (HI) tests for detecting HA-specific antibodies using canine H3N2 (CIV-H3N2), human pandemic H1N1 2009 (Human-pH1N1) and human seasonal H3N2 (Human-H3N2) as viral antigens. A total of 9,891 serum samples were obtained …

Hemagglutination (HA) and hemagglutination inhibition (HI) tests are conventional, well-known methods used for the detection of influenza A viruses (IAVs) and antibodies to IAVs, respectively. The sensitivity of HA and HI tests is usually affected by the compatibility of sialic acid (SA) receptors on red blood cells (RBCs) with the HA proteins of IAVs. In this study, the erythrocyte binding preferences of sixteen avian, swine and canine IAVs from Thailand were investigated using five erythrocyte sources: chicken, turkey, goose, guinea pig and horse RBCs. The results demonstrated that, turkey RBCs yielded the highest HA titers against most avian, swine and …
