Towards the Development of Microbial Ecotoxicology Testing Using Chlorpyrifos Contaminated Sediments and Marine Yeast Isolates as a Model.

Chlorpyrifos (CP), a widely used pesticide, and its metabolite 3,5,6-trichloro-2-pyridinol (3,5,6-TCP), are xenobiotic compounds detected in many biomes, notably in marine sediments, all over the world. These compounds are posing a serious environmental and health problem given their toxicity to wildlife and possible exposure effects to human neurodevelopment. Microorganisms at CP-impacted environments could harbor metabolic capabilities that can be used as indicators of the biological effects of the contaminant and could encode selected functions reactive against contaminants.

[Knowledge, attitudes and practice regarding dengue in a neighborhood forming part of the city of Cartagena].

Objective: Identifying attitudes, practice and knowledge regarding dengue in a neighborhood of the city of Cartagena.

Methods: This was a cross-sectional study of 870 people living in a neighborhood in the south-eastern part of Cartagena. Probabilistic, randomized, three-staged sampling was used; it was intended to ascertain attitudes, practice and knowledge about dengue.
