Abstract
Eastern equine encephalomyelitis virus (EEEV) is endemic in Michigan, showing an upsurge in human cases and in infections of white-tailed deer, horses, and other animals in the past decade (2010-2020). However, blood-host associations of the enzootic mosquito vector Culiseta melanura in the Great Lakes region are poorly known compared with other better-studied regions. Vertebrate sources of blood meals of Cs. melanura collected from resting boxes were determined through sequencing of the mitochondrial cytochrome B gene generated from polymerase chain reaction. Thirty-six unique avian species were detected in the samples, and 42% of the blood meals originated from only two species (American robin and northern cardinal). This result shows that although the Cs. melanura population investigated here used a wide range of avian hosts, American robin and northern cardinal are the main hosts in southwestern Michigan.
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
