The aim of our study was to find a possible existence of various vaccination effects on the formation of antibodies against three individual Borrelia afzelii strains (dead cell suspension) isolated from a vector, potential vector and host of this spirochaete, which makes this experiment unique in the research of Lyme disease causative agents. Three strains of Borrelia afzelii were isolated from...
Background & Objectives: Mosquitoes (Diptera: Culicidae) are medically considered as one of the most important species of insects in terms of disease transmission to human beings; hence, they can be vectors of remarkable diseases such as malaria, West Nile, dengue fever, yellow fever, and filariasis. This study aimed to determine the species diversity and larval habitat characteristics of mosqu...
Three media formulated from molasses and cornsteep liquor and another media based on the basal medium formulation of IPS-82 were assessed for the growth and production of insecticidal properties of B. thuringiensis H-14 .• Bacterial powders prepared from the broth cultures were assayed against the larvae of Culex pipiens and Anopheles stephensi. A standard powder of IPS-82 was included in ...
Understanding mosquito dispersal is critically important for vector-borne disease control and prevention. Mark-release-recapture methods using various marking techniques have made substantial contributions to the study of mosquito biology. However, the ability to mark naturally breeding mosquitoes noninvasively and with life-long retention has remained problematic. Here, we describe a method to...
In May 2001 a sample of Culex pipiens pipiens variety molestus Forskål from Marin County, California, collected as larvae and reared to adults, was found to show reduced resmethrin and permethrin knock-down responses in bottle bioassays relative to a standard susceptible Cx. pipiens quinquefasciatus Say colony (CQ1). Larval susceptibility tests, using CQ1 as standard susceptible, indicated that...
