We report transovarial transmission of Gamboa virus (Bunyavirus) in Aedeomyia squamipennis, a tropical mosquito which is active and bloodfeeding throughout the year. Gamboa virus was isolated during each of the 28 months of the study from every mosquito stage, including eggs, demonstrating that vertical transmission is a maintenance mechanism of this virus. The overall minimum infection rate was 5.1/1,000 mosquitoes. Identification of the 567 isolates by neutralization indicated that greater than or equal to 2 serotypes or subtypes of Gamboa virus circulate at the study site.
我们报告了甘博阿病毒（布尼亚病毒）在鳞斑伊蚊中的经卵传播，鳞斑伊蚊是一种全年活跃且吸血的热带蚊子。在为期28个月的研究中，每个月都从包括卵在内的蚊子各个发育阶段分离出了甘博阿病毒，这表明垂直传播是该病毒的一种维持机制。总体最低感染率为每1000只蚊子中有5.1只感染。通过中和试验对567株分离株进行鉴定表明，在研究地点有大于或等于2种血清型或亚型的甘博阿病毒在传播。
