Abstract

Feline Leukemia Virus is a retrovirus causing fatal disease in domestic cats. While FeLV has been controlled in many countries, it remains a major concern in Latin American countries. This study conducted an epidemiological survey of FeLV in 182 Chilean domestic cats using PCR to detect provirus infection. The results were analysed using Multivariate Logistic Regression to examine risk factors associated with FeLV detection. The FeLV prevalence was 54.95 %, and statistically significant associations (p < 0.05) were found for two protective factors and one risk factor. Cats from Concepcion city (95 %CI 0.08–0.56 %) and cats sampled in 2022 (95 %CI 0.1–0.06 %) had lower odds ratios for provirus positivity, whereas non-vaccinated cats (95 %CI 2.3–15.8 %) had an increased odds ratio. No other factors were statistically significant. The high FeLV prevalence is similar to other Latin American countries and the geographical differences highlighted in this study likely correspond to the socioeconomic status of the owners. This study highlights the need for improved FeLV control measures such as promoting FeLV vaccination, implementing health screening prior to adoption of new cats, and educating owners about FeLV to control its circulation.

智利城市猫（Felis catus）感染猫白血病病毒的高流行率和风险因素。

猫白血病病毒是一种逆转录病毒，可导致家猫患上致命疾病。虽然许多国家已经控制住了 FeLV，但在拉丁美洲国家，它仍然是一个令人担忧的主要问题。本研究利用 PCR 检测前病毒感染，对 182 只智利家猫进行了 FeLV 流行病学调查。研究结果采用多元逻辑回归法进行分析，以研究与检测到 FeLV 相关的风险因素。FeLV 感染率为 54.95%，发现两个保护因素和一个风险因素之间存在显著的统计学关联（p < 0.05）。康塞普西翁市的猫（95 %CI 0.08-0.56%）和2022年采样的猫（95 %CI 0.1-0.06%）的病毒阳性几率较低，而未接种疫苗的猫（95 %CI 2.3-15.8%）的几率较高。其他因素均无统计学意义。FeLV的高流行率与其他拉丁美洲国家相似，本研究中强调的地域差异很可能与猫主人的社会经济地位有关。这项研究强调了改进 FeLV 控制措施的必要性，例如推广 FeLV 疫苗接种、在领养新猫之前进行健康检查，以及对猫主人进行有关 FeLV 的教育以控制其传播。

期刊介绍： Research in Veterinary Science is an International multi-disciplinary journal publishing original articles, reviews and short communications of a high scientific and ethical standard in all aspects of veterinary and biomedical research. The primary aim of the journal is to inform veterinary and biomedical scientists of significant advances in veterinary and related research through prompt publication and dissemination. Secondly, the journal aims to provide a general multi-disciplinary forum for discussion and debate of news and issues concerning veterinary science. Thirdly, to promote the dissemination of knowledge to a broader range of professions, globally. High quality papers on all species of animals are considered, particularly those considered to be of high scientific importance and originality, and with interdisciplinary interest. The journal encourages papers providing results that have clear implications for understanding disease pathogenesis and for the development of control measures or treatments, as well as those dealing with a comparative biomedical approach, which represents a substantial improvement to animal and human health. Studies without a robust scientific hypothesis or that are preliminary, or of weak originality, as well as negative results, are not appropriate for the journal. Furthermore, observational approaches, case studies or field reports lacking an advancement in general knowledge do not fall within the scope of the journal.
