expression of mosquito active toxin genes by a colombian native strain of the gram-negative bacterium asticcacaulis excentricus.	mosquito control with biological insecticides, such as bacillus sp. toxins, has been used widely in many countries. however, rapid sedimentation away from the mosquito larvae feeding zone causes a low residual effect. in order to overcome this problem, it has been proposed to clone the bacillus toxin genes in aquatic bacteria which are able to live in the upper part of the water column. two strains of asticcacaulis excentricus were chosen to introduce the b. sphaericus binary toxin gene and b. t ...	2001	11285507
species composition and natural infectivity of anthropophilic anopheles (diptera: culicidae) in the states of córdoba and antioquia, northwestern colombia.	malaria is a serious health problem in the states of córdoba and antioquia, northwestern colombia, where 64.4% of total colombian cases were reported in 2007. because little entomological information is available in this region, the aim of this work was to identify the anopheles species composition and natural infectivity of mosquitoes distributed in seven localities with highest malaria transmission. a total of 1,768 anopheles mosquitoes were collected using human landing catches from march 200 ...	2009	20140372
