Midgut Microbial Community of Culex quinquefasciatus Mosquito Populations from India
The mosquito Culex quinquefasciatus is a ubiquitous species that serves as a major vector for west nile virus and lymphatic filariasis. Ingestion of bloodmeal by females triggers a series of physiological processes in the midgut and also exposes them to infection by these pathogens. The bacteria normally harbored in the midgut are known to influence physiology and can also alter the response to...
متن کاملIsolation and characterization of Vagococcus sp from midgut of Culex quinquefasciatus (Say) mosquito.
BACKGROUND & OBJECTIVES Mosquito gut is a rich source of microorganisms. These microorganisms exhibit close association and contribute various physiological processes taking place in mosquito gut. The present study is aimed to characterize two bacterial isolates M19 and GB11 recovered from the gut of Culex quinquefasciatus mosquito collected from Bhuj and Jamnagar districts of Gujarat, India. ...
متن کاملChryseobacterium culicis sp. nov., isolated from the midgut of the mosquito Culex quinquefasciatus.
A yellow-pigmented bacterial strain, R4-1A(T), isolated from the midgut of the mosquito Culex quinquefasciatus (a vector of lymphatic filariasis), was studied using a polyphasic approach. Cells of the isolate were rod-shaped and stained Gram-negative. A comparison of the 16S rRNA gene sequence of this organism with sequences of type strains of the most closely related species clearly showed an ...
متن کاملinsecticide-resistant mosquito Culex quinquefasciatus
Resistance to organophosphates in Culex mosquitoes is typically associated with increased activity of non-specific esterases. The commonest phenotype involves two elevated esterases, A2 and B2, while some strains have elevation of esterase B1 alone. Overexpression of the two B esterase electromorphs is due to gene amplification. Full-length cDNAs coding for amplified esterase B genes from a res...
متن کاملToxic Response of Mosquito Culex Quinquefasciatus (Diptera: Culicidae) to some Agricultural Pesticides (Butachlor and Pertilachlor)
Background: The expansion of herbicide used in aquatic ecosystems as well as in terrestrial if is not properly controlled may produce harmful effects on freshwater fisheries. Residue limits of these agricultural chemicals in tropical fishery waters should be established. The aim of this study was to determine the acute toxicity of butachlor and pertilachlor as potential dangerous herbicides to ...
