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 ...
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 ...
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 ...
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 ...
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 ...
Rickettsia parkeri and Candidatus Rickettsia andeanae in Amblyomma maculatum group ticks
(Centers for Disease Control and Prevention (CDC), 2020-02)
We determined prevalence of Rickettsia spp. in 172 ticks of the Amblyomma maculatum group collected from 16 urban sites in Oklahoma City, Oklahoma, USA, during 2017 and 2018. Most ticks (59.3%) were collected from 1 site; ...
Spatial and temporal risk as drivers for adoption of foot and mouth disease vaccination
(Elsevier, 2018-08-09)
Identifying the drivers of vaccine adoption decisions under varying levels of perceived disease risk and benefit provides insight into what can limit or enhance vaccination uptake. To address the relationship of perceived ...
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 ...
