Abstract

Influenza A virus (IAV) is a zoonotic pathogen with a broad host range, including birds, humans, and various mammalian species. Domestic cats have been documented as incidental hosts, particularly in regions with ongoing avian influenza outbreaks. Cats are important companion animals in Dhaka, Bangladesh; however, data on IAV infection in this population are limited. This study aimed to investigate the presence of IAV in domestic cats in Dhaka through molecular surveillance. A total of 50 nasal swab samples were collected from domestic cats with mild respiratory signs presented from different areas of Dhaka city. Samples were tested for IAV using real-time reverse-transcription polymerase chain reaction (qRT-PCR) targeting the matrix (M) gene. All 50 samples tested negative for IAV. No evidence of IAV infection was found within the sampled population, suggesting low or no detectable zoonotic risk from domestic cats during the study period. These findings provide baseline data on IAV surveillance in domestic cats in Dhaka. However, given the limited sample size and sampling period, larger longitudinal surveillance studies are warranted to better assess the potential for IAV spillover in high-risk settings.

分子监测未发现达卡家猫感染甲型流感。

甲型流感病毒（IAV）是一种人畜共患病原体，宿主范围广泛，包括鸟类、人类和各种哺乳动物。家猫已被记录为偶然宿主，特别是在持续爆发禽流感的地区。在孟加拉国的达卡，猫是重要的伴侣动物；然而，这一人群中禽流感病毒感染的数据有限。本研究旨在通过分子监测方法调查达卡地区家猫中IAV的存在情况。从达卡市不同地区出现轻度呼吸症状的家猫身上共收集了50份鼻拭子样本。采用针对基质(M)基因的实时逆转录聚合酶链反应（qRT-PCR）检测样品的IAV。所有50个样本的IAV检测均呈阴性。在抽样人群中未发现内窥病毒感染的证据，这表明在研究期间家猫的人畜共患风险很低或没有检测到。这些发现为达卡家猫的IAV监测提供了基线数据。然而，鉴于样本量和采样周期有限，有必要进行更大规模的纵向监测研究，以更好地评估高风险环境中IAV溢出的可能性。

期刊介绍： EcoHealth aims to advance research, practice, and knowledge integration at the interface of ecology and health by publishing high quality research and review articles that address and profile new ideas, developments, and programs. The journal’s scope encompasses research that integrates concepts and theory from many fields of scholarship (including ecological, social and health sciences, and the humanities) and draws upon multiple types of knowledge, including those of relevance to practice and policy. Papers address integrated ecology and health challenges arising in public health, human and veterinary medicine, conservation and ecosystem management, rural and urban development and planning, and other fields that address the social-ecological context of health. The journal is a central platform for fulfilling the mission of the EcoHealth Alliance to strive for sustainable health of people, domestic animals, wildlife, and ecosystems by promoting discovery, understanding, and transdisciplinarity. The journal invites substantial contributions in the following areas: One Health and Conservation Medicine o Integrated research on health of humans, wildlife, livestock and ecosystems o Research and policy in ecology, public health, and agricultural sustainability o Emerging infectious diseases affecting people, wildlife, domestic animals, and plants o Research and practice linking human and animal health and/or social-ecological systems o Anthropogenic environmental change and drivers of disease emergence in humans, wildlife, livestock and ecosystems o Health of humans and animals in relation to terrestrial, freshwater, and marine ecosystems Ecosystem Approaches to Health o Systems thinking and social-ecological systems in relation to health o Transdiiplinary approaches to health, ecosystems and society.
