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 ...
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 ...
Variation in tick load among bird body parts: Implications for studying the role of birds in the ecology and epidemiology of tick-borne diseases
(Oxford University Press (OUP), 2020)
Wild birds play important roles in the maintenance and dispersal of tick populations and tick-borne pathogens, yet in field studies of tick-borne disease ecology and epidemiology there is limited standardization of how ...
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 ...
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 ...
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) ...
Active surveillance to update county scale distribution of four tick species of medical and veterinary importance in Oklahoma
(Society for Vector Ecology, 2017-06)
The incidence of tick-borne disease continues to increase in humans and companion animals in the United States, yet distribution maps for several tick vectors in Oklahoma, including Dermacentor variabilis, Dermacentor ...
Sporogonic development of cultured Plasmodium falciparum in six species of laboratory-reared Anopheles mosquitoes
(American Society of Tropical Medicine and Hygiene, 1994)
Sporogonic development of cultured Plasmodium falciparum was compared in six species of Anopheles mosquitoes. A reference species, A. gambiae, was selected as the standard for comparison. Estimates of absolute densities ...
Concentration of human erythrocytes by anopheline mosquitoes (Diptera: Culicidae) during feeding
(Oxford University Press (OUP), 1991-11)
Erythrocyte densities in the blood meals of six Anopheles mosquito species were compared with those of human host erythrocyte densities. During engorgement, An. gambiae Giles and An. stephensi Liston concentrated erythrocytes ...
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 ...
