Abstract

Objective: This study aims to determine the seroprevalence of African swine fever (ASF) in pigs for slaughter in Leyte, Philippines. It underpins the concept that recovered and infected pigs from ASF are likely sent for slaughter to avoid perceived economic losses.

Materials and methods: A cross-sectional study was conducted from March to June 2023 in eight abattoirs, each representing both a city and a municipality in Leyte province. A total of 218 blood samples from 78 farms were examined for ASF virus (ASFV) (VP72) antibodies using a blocking enzyme-linked immunosorbent assay (ELISA) method. Descriptive and seroprevalence analyses were performed.

Results: ASF antibodies were detected in pigs for slaughter from abattoirs in Baybay and Ormoc cities, showing a seroprevalence of 3.57% (1/28 pigs) and 2.27% (1/44 pigs), respectively. An apparent absence of ASF antibodies was observed among pigs for slaughter in Isabel, Villaba, Abuyog, Kananga, Dulag, and Macarthur. The farm-level seroprevalence was 2.56% (95% CI: 0.71%-8.88%), while the pig-level seroprevalence was 0.91% (95% CI: 0.25%-3.27%).

Conclusion: Detecting ASF antibodies among pigs for slaughter implies exposure to the virus from the farm of origin. This means that, on some farms, ASF remains unreported or undiagnosed. Active surveillance is needed for early case detection and rapid response to control the spread of ASF in the country.

菲律宾莱特岛待宰猪的非洲猪瘟血清流行率。

研究目的本研究旨在确定菲律宾莱特岛待宰猪的非洲猪瘟（ASF）血清流行率。它证实了这样一个概念，即非洲猪瘟的康复猪和感染猪很可能被送去屠宰，以避免经济损失：2023 年 3 月至 6 月，在莱特省的八个屠宰场进行了横断面研究，每个屠宰场代表一个城市和一个市。采用阻断酶联免疫吸附试验（ELISA）方法对来自 78 个农场的 218 份血样进行了 ASF 病毒（ASFV）（VP72）抗体检测。对结果进行了描述性分析和血清流行率分析：在拜拜市和奥尔莫克市屠宰场的待宰猪中检测到 ASF 抗体，血清流行率分别为 3.57%（1/28 头猪）和 2.27%（1/44 头猪）。在伊莎贝尔（Isabel）、维拉巴（Villaba）、阿布约格（Abuyog）、卡南加（Kananga）、杜拉格（Dulag）和麦克阿瑟（Macarthur）的屠宰猪中，明显没有发现 ASF 抗体。农场血清流行率为 2.56%（95% CI：0.71%-8.88%），而猪血清流行率为 0.91%（95% CI：0.25%-3.27%）：结论：在屠宰用猪中检测到 ASF 抗体意味着从原产地猪场接触到了病毒。这意味着，在某些猪场，ASF 仍未报告或未确诊。需要积极开展监测工作，以便及早发现病例并做出快速反应，控制 ASF 在该国的传播。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
