Development of a loop-mediated isothermal amplification (LAMP) assay for rapid screening of ticks and fleas for spotted fever group rickettsia
(Public Library of Science (PLoS), 2018-02-01)Background: The importance of tick and flea-borne rickettsia infections is increasingly recognized worldwide. While increased focus has shifted in recent years to the development of point-of-care diagnostics for various ... -
Differences in mosquito communities in six cities in Oklahoma
(Oxford University Press (OUP), 2019-04-05)Vector-borne diseases in the United States have recently increased as a result of the changing nature of vectors, hosts, reservoirs, pathogens, and the ecological and environmental conditions. Current information on vector ... -
Exflagellation responses of cultured Plasmodium falciparum (Haemosporida: Plasmodiidae) gametocytes to human sera and midguts of anopheline mosquitoes (Diptera: Culicidae)
(Oxford University Press (OUP), 1994)The process of exflagellation was quantified for cultured Plasmodium falciparum gametocytes exposed to human sera and midgut homogenates from six vector species of Anopheles mosquitoes. Neither serum factors related to ... -
Exogenously scavenged and endogenously synthesized heme are differentially utilized by Mycobacterium tuberculosis
(American Society for Microbiology, 2022-10-26)Heme is both an essential cofactor and an abundant source of nutritional iron for the human pathogen Mycobacterium tuberculosis. While heme is required for M. tuberculosis survival and virulence, it is also potentially ... -
Exposure and risk factors to Coxiella burnetii, spotted fever group and typhus group rickettsiae, and Bartonella henselae among volunteer blood donors in Namibia
(Public Library of Science (PLoS), 2014-09-26)Background: The role of pathogen-mediated febrile illness in sub-Saharan Africa is receiving more attention, especially in Southern Africa where four countries (including Namibia) are actively working to eliminate malaria. ... -
Flea-borne rickettsioses: Ecologic considerations
(Centers for Disease Control and Prevention (CDC), 1997-07)Ecologic and economic factors, as well as changes in human behavior, have resulted in the emergence of new and the reemergence of existing but forgotten infectious diseases during the past 20 years. Flea-borne disease ... -
Immunological factor that affects Anopheles gambiae survival
(The American Mosquito Control Association, 1995)High titers of antibodies against Anopheles gambiae midguts were produced in New Zealand rabbits to identify midgut targets for an antimosquito vaccine. The serum from one of 8 rabbits (designated R2B6) killed 71.6% (Abbott's ... -
Impact of variations in temperature on early Plasmodium falciparum development in Anopheles stephensi
(Cambridge University Press (CUP), 1995) -
Ingestion of Plasmodium falciparum sporozoites during transmission by anopheline mosquitoes
(American Society of Tropical Medicine and Hygiene, 1992)We investigated the process of sporozoite transmission during blood feeding for Anopheles gambiae and An. stephensi experimentally infected with Plasmodium falciparum. When infective mosquitoes were fed 22-25 days postinfection ... -
Invasive plants as foci of mosquito-borne pathogens: Red cedar in the southern Great Plains of the USA
(Springer Science and Business Media LLC, 2021-10-05)West Nile virus (WNV) is the most significant mosquito-borne disease affecting humans in the United States. Eastern redcedar (ERC) is a native encroaching plant in the southern Great Plains that greatly alters abiotic ... -
Knowledge and practices of residents in two north Namibian towns with regard to rabies and pet care
(Informa UK Limited, 2014)Recent studies have highlighted the epidemiology of rabies in southern Africa and the unique nature of kudu rabies in Namibia. However, the serious effect on human populations in northern Namibia lacks focused attention. ... -
Knowledge, attitudes, and practices regarding ticks, tick-borne pathogens, and tick prevention among beef producers in Oklahoma
(Society of Southwestern Entomologists, 2020-06)Tick-borne diseases are increasing in the United States, with regional need to understand how knowledge of ticks translates into preventative behavior among specific occupational groups. Little is known regarding what ... -
Low seroprevalence of antibodies to Toxoplasma gondii in blood donors in central Namibia
(Informa UK Limited, 2014)Although emphasis has been placed on research relating to human immunodeficiency virus (HIV), tuberculosis and malaria, several researchers in Africa are focusing on other threats to human health, such as neglected tropical ... -
Mapping of schistosomiasis and soil-transmitted helminths in Namibia: The first large-scale protocol to formally include rapid diagnostic tests
(Public Library of Science (PLoS), 2015-07-21)Background: Namibia is now ready to begin mass drug administration of praziquantel and albendazole against schistosomiasis and soil-transmitted helminths, respectively. Although historical data identifies areas of transmission ... -
Mosquito community and West Nile virus risk on a National Guard training base in Oklahoma
(The American Mosquito Control Association, 2020-06)Military bases are important areas for mosquito surveillance to maintain active duty combat readiness and protect training exercises. The aim of this study was to assist Camp Gruber National Guard training facility personnel ... -
Mosquito ingestion of antibodies against mosquito midgut microbiota improves conversion of ookinetes to oocysts for Plasmodium falciparum, but not P. yoelii
(Elsevier BV, 2011-07-13)The mosquito midgut is a site of complex interactions between the mosquito, the malaria parasite and the resident bacterial flora. In laboratory experiments, we observed significant enhancement of Plasmodium falciparum ... -
