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 ...
High prevalence of "Candidatus Rickettsia andeanae" and apparent exclusion of Rickettsia parkeri in adult Amblyomma maculatum (Acari: Ixodidae) from Kansas and Oklahoma
(Elsevier BV, 2015-03-13)
Amblyomma maculatum (the Gulf Coast tick), an aggressive, human-biting, Nearctic and Neotropical tick, is the principal vector of Rickettsia parkeri in the United States. This pathogenic spotted fever group Rickettsia ...
Physical activity engagement outside of college physical education: Application of the transtheoretical model
(P N G Publications, 2021-09-01)
Objective: In this study, we examined physical activity (PA) engagement outside of college physical education (PE) classes using the Transtheoretical Model (TTM). Methods: Overall, 414 university students enrolled in PE ...
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 ...
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 ...
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 ...
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 ...
Using human-centered design to develop an innovative teen pregnancy prevention program: Lessons learned from a case study
(Scientific Research Publishing, 2022)
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) ...
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 ...
