Publication Metadata only Detection of neutralizing antibody against porcine epidemic diarrhea virus in subclinically infected finishing pigs(2018-01-01) Naoki Koike; Thi Ngan Mai; Mamoru Shirai; Meiko Kubo; Kazuhiro Hata; Nobuyuki Marumoto; Shinji Watanabe; Yosuke Sasaki; Shuya Mitoma; Kosuke Notsu; Tamaki Okabayashi; Anuwat Wiratsudakul; Emmanuel Kabali; Junzo Norimine; Satoshi Sekiguchi; Vietnam National University Hanoi; National Institute of Infectious Diseases; Mahidol University; University of Miyazaki; Miyakonojo Livestock Hygiene Service Center; Zambia Medicines Regulatory Authority; Miyakonojyo Meat Inspection Office) of the case farms were indeed positive for PEDV. The proportion of seropositive animals from case farms was 63.7%, significantly different from that of non-case farms (4.3%, P<0.05). In both case and non-case farms, the proportion of seropositive animals... in farrow-to-finish farms was significantly higher than in wean-to-finish farms (P<0.05). Seropositive animals in non-case farms were detected by NT in a sero-survey by sampling at slaughterhouses. Therefore, subclinically infected pigs should be consideredPublication Metadata only Simulation modeling of influenza transmission through backyard pig trade networks in a wildlife/livestock interface area(2019-09-01) Jessica Mateus-Anzola; Anuwat Wiratsudakul; Oscar Rico-Chávez; Rafael Ojeda-Flores; Universidad Nacional Autónoma de México, Facultad de Medicina; Mahidol University© 2019, Springer Nature B.V. Influenza constitutes a challenge to animal and human health. It is a highly contagious disease with wildlife reservoirs and considered as endemic among swine populations. Pigs are crucial in the disease dynamics due... to their capacity to generate new reassortant viruses. The risk of informal animal trade in the spread of zoonotic diseases is well recognized worldwide. Nevertheless, the contribution of the backyard pig trade network in the transmission of influenza in a wildlifePublication Open Access The exploration of financial impacts among three stakeholders during the 2016 Foot-and-Mouth Disease Outbreak in a Dairy Cooperative, Chiang Mai province, Thailand(2019) Wilasinee Jongthanachote; Manthita Poontrakulkeat; Kwankla Mungthisarn; Anuwat Wiratsudakul; Sineenard Jiemtaweeboon; วิลาสินี จงธนโชติ; มัณฑิตา พูนตระกูลเกียรติ; ขวัญกล้า มังธิสาร; อนุวัตน์ วิรัชสุดากุล; สินีนาถ เจียมทวีบุญ; Mahidol University.

Two independent FMD outbreak data sources including data from the livestock authorities and survey questionnaires were... analyzed using Chapman estimator and Chao estimator. Results showed that the estimated number of FMD outbreak farms was 264 (95% CI = 250, 277) and 273 (95% CI = 259, 292) farms based on the Chapman estimator and Chao estimator, respectively.

El-Khaiat; Junzo Norimine; Satoshi Sekiguchi; Graduate School of Medicine and Veterinary Medicine; Benha University; Mahidol University; University of Miyazakiand the estimated number of introduced BLV-infected cattle. Remarkably, the introduction of approximately six cattle allowed at least one BLV-infected animal to be added to the farm in the worst-case scenario. These data suggest a high risk of BLV infection on farms... spreads easily without detection by farmers and veterinarians due to the lack of obvious clinical signs. Cattle movement strongly contributes to the inter-farm transmission of BLV. This study quantified the farm-level risk of BLV introduction using aPublication Open Access Intervention models to solve the declining problem of swamp buffalo (Bubalus bubalis) population in Ubon Ratchathani province of Thailand(2017) Anuwat Wiratsudakul; Poonyapat Sedwisai; Teeraporn Makaroon; Sunisa Kinawong; Kittipat Angchokchatchawal; Bopit Puyati; Surapong Senayai; Mahidol University. Faculty of Veterinary ScienceSwamp buffalo population in Thailand has dramatically decreased in the last three decades. The present study was conducted to predict trends and future population size of swamp buffaloes and to formulate different interventions to prevent further decline and rejuvenate the existing population. The study is based on a questionnaire survey to access information regarding buffalo husbandry and marketing. Based on derived data, age-structured Leslie matrix population model was constructed to predict the population of the buffalo cows in the coming decades. Three different intervention models were subsequently proposed including Buffalo bank campaign, prohibition of slaughtering buffalo cows and the combination of these two interventions. A total of 398 farmers rearing buffaloes were interviewed and data encompassed information on 1,366 buffaloes (418 buffalo bulls and 948 cows) were retrieved. Initial buffalo cow population in Ubon Ratchathani province was estimated to be 42,766 heads. The number was projected to decline by 36% in the next ten years, with population growth rate estimated to be 0.93. The most feasible and sustainable intervention was to carry out both campaigns simultaneously. This strategy allows the slaughtering prohibition to be successful with the support from the Buffalo bank. These campaigns should be rigorously implemented to maintain this valuable livestock resource. The present model might be implemented for similar studies in different parts of the developing world.
