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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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) ... -
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 ... -
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 ... -
Sporozoite transmission by Anopheles freeborni and Anopheles gambiae experimentally infected with Plasmodium falciparum
(The American Mosquito Control Association, 1992)A micro-membrane feeding technique was used to evaluate sporozoite transmission for Anopheles freeborni and An. gambiae experimentally infected with Plasmodium falciparum. From cohorts of infected mosquitoes with equivalent ... -
Updated checklist of the mosquitoes of Oklahoma including new state records and West Nile virus vectors, 2003-06
(The American Mosquito Control Association, 2015-12)The mosquito fauna of Oklahoma has not been evaluated since 1965 and no report has been published concerning species associated with urban areas in the state. Mosquito collections were conducted as part of the West Nile ... -
Updated distribution of Aedes albopictus in Oklahoma, and implications in arbovirus transmission
(The American Mosquito Control Association, 2015-03)A series of statewide surveys were conducted in Oklahoma in the summers between 1991 and 2004 to identify the distribution of Aedes albopictus. Adult mosquitoes were identified in 63 counties, bringing the currently known ...
