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 ... -
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 ... -
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 ... -
Prior blood feeding effects on susceptibility of Anopheles gambiae (Diptera: Culicidae) to infection with cultured Plasmodium falciparum (Haemosporida: Plasmodiidae)
(Oxford University Press (OUP), 1994)We examined the relative susceptibilities of Anopheles gambiae Giles of different physiological ages to infection with cultured Plasmodium falciparum (Welch). Cohorts of mosquitoes were divided into three groups; one was ... -
Quantitation of Plasmodium falciparum sporozoites transmitted in vitro by experimentally infected Anopheles gambiae and Anopheles stephensi
(American Society of Tropical Medicine and Hygiene, 1991)The frequency and numbers of Plasmodium falciparum sporozoites transmitted in vitro and corresponding sporozoite loads were determined for experimentally infected Anopheles gambiae and An. stephensi. Geometric mean (GM) ... -
Quantitative synthesis of the role of birds in carrying ticks and tick-borne pathogens in North America
(Springer Science and Business Media LLC, 2016-09-26)Birds play a central role in the ecology of tick-borne pathogens. They expand tick populations and pathogens across vast distances and serve as reservoirs that maintain and amplify transmission locally. Research into the ... -
Questing behavior and analysis of tick-borne bacteria in Ixodes scapularis (Acari: Ixodidae) in Oklahoma
(Oxford University Press (OUP), 2018-08-06)The blacklegged tick, Ixodes scapularis Say (Acari: Ixodidae), is an economically important tick that affects veterinary and public health, but it can be difficult to collect in Oklahoma. The primary goal of this research ... -
Recombinase polymerase amplification (RPA) with lateral flow detection for three Anaplasma species of importance to livestock health
(Springer Science and Business Media LLC, 2021)Anaplasma marginale, A. ovis, and A. phagocytophilum are the causative agents of bovine anaplasmosis, ovine anaplasmosis, and granulocytic anaplasmosis, respectively. The gold standard for diagnosis of post-acute and ... -
Reverse transcriptase PCR amplification of Rickettsia typhi from infected mammalian cells and insect vectors
(American Society for Microbiology, 1998-06)We developed a reverse transcriptase PCR assay to detect expression of 120- and 17-kDa antigen genes in Rickettsia typhi. Infected Vero cell and flea RNAs were reverse transcribed by using random hexamers. The cDNA was ... -
Risk assessment of flavivirus transmission in Namibia
(Elsevier BV, 2014-05-25)The role of arboviruses causing acute febrile illness in sub-Saharan Africa is receiving more attention. Reports of dengue in tourists were published nearly 10 years ago in Namibia, but the current epidemiology of arboviruses ... -
Risk of encountering questing ticks (Ixodidae) and the prevalence of tickborne pathogens in Oklahoma state parks
(Society of Southwestern Entomologists, 2018-06)State parks, used by many for various kinds of recreation, are also places where people and their companion animals are exposed to ticks and tickborne pathogens. While most studies in state parks in the United States have ... -
Risk of encountering ticks and tick-borne pathogens in a rapidly growing metropolitan area in the U.S. Great Plains
(Elsevier BV, 2016-10-14)The prevalence of tick-borne diseases has increased dramatically in many urban areas of the U.S., yet little is known about the ecology of ticks and tick-borne pathogens in relation to characteristics of North American ... -
Sporogonic development of cultured Plasmodium falciparum in six species of laboratory-reared Anopheles mosquitoes
