Abstract
During the 2024 Oropouche virus (OROV) outbreak in South America, mosquito surveillance led to the identification of pools of Culex quinquefasciatus infected with the virus. Because of the outbreak strain's status as a novel reassortment and the novel sequela discovered during this outbreak, concerns arose about Culex species as potential vectors in the continental United States. To assess the risk posed by Cx. quinquefasciatus and the closely related species Culex pipiens, the vector competence of mosquitoes reared from eggs collected in Dallas, TX, and New Jersey was examined. Three replicates of an infectious bloodmeal were offered to Cx. quinquefasciatus at generations F2, F4, and F9, resulting in 0/305 individuals with midgut infections. One infectious bloodmeal was offered to Cx. pipiens at generation F4, with 0/120 resulting midgut infections. These data, which align with other recent publications, indicate that United States populations of Cx. quinquefasciatus and Cx. pipiens are not competent vectors of the outbreak strain of OROV.
期刊介绍:
The American Journal of Tropical Medicine and Hygiene, established in 1921, is published monthly by the American Society of Tropical Medicine and Hygiene. It is among the top-ranked tropical medicine journals in the world publishing original scientific articles and the latest science covering new research with an emphasis on population, clinical and laboratory science and the application of technology in the fields of tropical medicine, parasitology, immunology, infectious diseases, epidemiology, basic and molecular biology, virology and international medicine.
The Journal publishes unsolicited peer-reviewed manuscripts, review articles, short reports, images in Clinical Tropical Medicine, case studies, reports on the efficacy of new drugs and methods of treatment, prevention and control methodologies,new testing methods and equipment, book reports and Letters to the Editor. Topics range from applied epidemiology in such relevant areas as AIDS to the molecular biology of vaccine development.
The Journal is of interest to epidemiologists, parasitologists, virologists, clinicians, entomologists and public health officials who are concerned with health issues of the tropics, developing nations and emerging infectious diseases. Major granting institutions including philanthropic and governmental institutions active in the public health field, and medical and scientific libraries throughout the world purchase the Journal.
Two or more supplements to the Journal on topics of special interest are published annually. These supplements represent comprehensive and multidisciplinary discussions of issues of concern to tropical disease specialists and health issues of developing countries
