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 ... -
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 ... -
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 ... -
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 ... -
Sylvatic infestation of Oklahoma reptiles with immature Ixodes scapularis (Acari: Ixodidae)
(Oxford University Press (OUP), 2015-09)Reptiles were collected in nine counties in Oklahoma from September 2002 to May 2004 and examined for Ixodes scapularis (Say) larvae and nymphs to determine seasonal incidence and prevalence of these ticks. In total, 209 ... -
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 ... -
Walking cadence (steps/min) and intensity in 21-40 year olds: CADENCE-adults
(Springer Science and Business Media LLC, 2019-01-17)Background: Previous studies have reported that walking cadence (steps/min) is associated with absolutely-defined intensity (metabolic equivalents; METs), such that cadence-based thresholds could serve as reasonable proxy ... -
Waveforms from stylet probing of the mosquito Aedes aegypti (Diptera: Culicidae) measured by AC-DC electropenetrography
(Oxford University Press (OUP), 2020)Electropenetrography (EPG) has been used for many years to visualize unseen stylet probing behaviors of plant-feeding piercing-sucking insects, primarily hemipterans. Yet, EPG has not been extensively used with blood-feeding ...
