Invasive woody plants as foci of tick-borne pathogens: Eastern redcedar in the southern Great Plains
(Society for Vector Ecology, 2021-06)Habitat preference and usage by disease vectors are directly correlated with landscapes often undergoing anthropogenic environmental change. A predominant type of land use change occurring in the United States is the ... -
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 ... -
Landscape and anthropogenic factors associated with adult Aedes aegypti and Aedes albopictus in small cities in the southern Great Plains
(MDPI AG, 2020-10-13)As mosquito-borne diseases are a growing human health concern in the United States, the distribution and potential arbovirus risk from container-breeding Aedes mosquitoes is understudied in the southern Great Plains. The ... -
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 ... -
Mosquito-borne parasites in the Great Plains: Searching for vectors of nematodes and avian malaria parasites
(Elsevier BV, 2021)Vector-borne diseases in the United States have recently increased as a result of the changing nature of vectors, hosts, reservoirs, parasite/pathogens, and the ecological and environmental conditions. While most focus has ... -
Mycobacteria, metals, and the macrophage
(Wiley, 2015-03)Mycobacterium tuberculosis is a facultative intracellular pathogen that thrives inside host macrophages. A key trait of M. tuberculosis is to exploit and manipulate metal cation trafficking inside infected macrophages to ... -
Neglected tropical diseases of Namibia: Unsolved mysteries
(Elsevier BV, 2012-09-21)Neglected tropical diseases (NTDs) are diseases most commonly found in settings of poverty and are responsible for the morbidity and/or mortality of millions each year. As an upper-middle income country, Namibia is not ... -
New records of Aedes aegypti in southern Oklahoma, 2016
(The American Mosquito Control Association, 2017-03)Aedes aegypti is an important subtropical vector species and is predicted to have a limited year-round distribution in the southern United States. Collection of the species has not been officially verified in Oklahoma since ... -
Noninfectious sporozoites in the salivary glands of a minimally susceptible anopheline mosquito
(American Society of Parasitologists, 1995-12)In studies to evaluate vector-malaria parasite relationships, we have found that Anopheles albimanus is minimally susceptible to the rodent malaria parasite Plasmodium yoelii. Normally, less than 10% of A. albimanus develop ... -
Pictorial key for identification of immature stages of common ixodid ticks found in pastures in Oklahoma
(Society of Southwestern Entomologists, 2017-03)Many species of ixodid ticks in the United States are parasitic on cattle and pose a threat to veterinary and public health for those engaged in occupations in pasturelands. While encountered often, nymphs and larvae of ... -
Plasmodium falciparum: Release of circumsporozoite protein by sporozoites in the mosquito vector
(Elsevier BV, 1992)The release of circumsporozoite (CS) protein by Plasmodium falciparum sporozoites was investigated to identify factors regulating this process within infected Anopheles gambiae mosquitoes. The potential for sporozoites to ... -
Plasmodium falciparum: The population structure of mature gametocyte cultures has little effect on their innate fertility
(Elsevier BV, 1994)In vitro cultured Plasmodium falciparum gametocytes were fed to Anopheles gambiae (G3) mosquitoes to identify parasite population characteristics useful for predicting successful mosquito infections. Parameters were collected ... -
Population dynamics of Plasmodium falciparum sporogony in laboratory-infected Anopheles gambiae
(American Society of Parasitologists, 1992)The population dynamics of cultured Plasmodium falciparum parasites was examined during their sporogonic development in Anopheles gambiae mosquitoes. Estimates of absolute densities were determined for each life stage, and ... -
PPE surface proteins are required for heme utilization by Mycobacterium tuberculosis
(American Society for Microbiology, 2017-03-08)Iron is essential for replication of Mycobacterium tuberculosis, but iron is efficiently sequestered in the human host during infection. Heme constitutes the largest iron reservoir in the human body and is utilized by many ... -
Predicting key malaria transmission factors, biting and entomological inoculation rates, using modelled soil moisture in Kenya
(Wiley, 1998-10)While malaria transmission varies seasonally, large inter-annual heterogeneity of malaria incidence occurs. Variability in entomological parameters, biting rates and entomological inoculation rates (EIR) have been strongly ... -
Prevalence of Babesia spp., Ehrlichia spp., and tick infestations in Oklahoma black bears (Ursus americanus)
(Wildlife Disease Association, 2017-10)American black bears (Ursus americanus) are commonly infested with ticks throughout their range, but there are few surveys for tick-borne disease agents in bears. To characterize tick infestations and determine the prevalence ... -
