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 ...
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 ...
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 ...
Mycobacteria, metals, and the macrophage
(Wiley, 2015-03)
Mycobacterium tuberculosis is a facultative intracellular pathogen that thrives inside host macrophages. A key trait of M. tuberculosis is to exploit and manipulate metal cation trafficking inside infected macrophages to ...
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 ...
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 ...
PPE surface proteins are required for heme utilization by Mycobacterium tuberculosis
(American Society for Microbiology, 2017-03-08)
Iron is essential for replication of Mycobacterium tuberculosis, but iron is efficiently sequestered in the human host during infection. Heme constitutes the largest iron reservoir in the human body and is utilized by many ...
