First detection of Rickettsia typhi and Rickettsia felis in fleas collected from client-owned companion animals in the southern Great Plains
(Oxford University Press (OUP), 2017-03-25)Flea-borne rickettsiosis occurs worldwide and includes a number of pathogens, namely, Rickettsia typhi and Rickettsia felis. Most studies in the United States have occurred in southern Texas and California where flea-borne ... -
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 ... -
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 ... -
Impact of inter- and intra-specific competition among larvae on larval, adult, and life-table traits of Aedes aegypti and Aedes albopictus females
(Wiley, 2015-12-08)1. Few studies have taken a comprehensive approach of measuring the impact of inter- and intra-specific larval competition on adult mosquito traits. In this study, the impact of competition among Aedes aegypti (L.) and A. ... -
Invasive plants as foci of mosquito-borne pathogens: Red cedar in the southern Great Plains of the USA
(Springer Science and Business Media LLC, 2021-10-05)West Nile virus (WNV) is the most significant mosquito-borne disease affecting humans in the United States. Eastern redcedar (ERC) is a native encroaching plant in the southern Great Plains that greatly alters abiotic ... -
Landscape and anthropogenic factors associated with adult Aedes aegypti and Aedes albopictus in small cities in the southern Great Plains
(MDPI AG, 2020-10-13)As mosquito-borne diseases are a growing human health concern in the United States, the distribution and potential arbovirus risk from container-breeding Aedes mosquitoes is understudied in the southern Great Plains. The ... -
Low seroprevalence of antibodies to Toxoplasma gondii in blood donors in central Namibia
