This article investigates the role of local fauna in Western Kazakhstan as potential reservoirs of the camelpox virus (CMLV). The study emphasizes analyzing possible sources and transmission pathways of the virus using polymerase chain reaction (PCR) and serological methods, including virus neutralization tests and enzyme-linked immunosorbent assays (ELISA). Samples were collected from both young and adult camels, as well as rodents, ticks and blood-sucking insects in the Mangystau and Atyrau regions. The PCR results revealed the absence of viral DNA in rodents, ticks and blood-sucking insects; also, the ELISA test did not detect specific antibodies in rodents. These findings suggest that these groups of fauna likely do not play a significant role in the maintenance and spread of CMLV. Consequently, the primary sources of transmission are likely other factors, potentially including the camels themselves. The study's results indicate the need to reassess current hypotheses regarding infection reservoirs and to explore alternative sources to enhance strategies for the control and prevention of the camelpox virus.
本文研究了哈萨克斯坦西部地区的当地动物群在作为骆驼痘病毒(CMLV)潜在宿主方面的作用。本研究强调使用聚合酶链反应(PCR)和血清学方法(包括病毒中和试验和酶联免疫吸附试验(ELISA))分析病毒的可能来源和传播途径。在曼格斯套州和阿特劳地区,从小型骆驼和成年骆驼,以及啮齿动物、蜱和吸血昆虫中采集了样本。PCR 结果显示,啮齿动物、蜱和吸血昆虫中未检测到病毒 DNA;此外,ELISA 试验也未在啮齿动物中检测到特异性抗体。这些发现表明,这些动物群在 CMLV 的维持和传播中可能没有发挥重要作用。因此,主要的传播源可能是其他因素,可能包括骆驼本身。本研究结果表明,有必要重新评估当前关于感染宿主的假设,并探索替代来源,以加强控制和预防骆驼痘病毒的策略。
