Objective To identify the awareness, attitudes and practices related to dengue in owners and workers of tire ships, as well as the levels of mosquito infestation in tire shops in Atlántico department - Colombia. Methods We conducted a descriptive study. The variables were described as percentages and measures of central tendency and dispersion. Index of larval infestation and containers were calculated in each of the municipalities studied. We visited and inspected 111 tire shops. 26.1 % (29/111) of these were found positive for Ae. aegypti larvae. The municipalities of Piojó, Santo Tomás, Santa Lucia, Sabanagrande and Luruaco were characterized by a higher larval infestation index. Results Regarding dengue, 90.9 % of respondents considered it a problem for them and their families. 94.6 % know that is transmitted by mosquitoes. 91.1 % know the vector larvae under the name "sarapico", 3.6 % as "gusarapo". 98.2 % felt that there is a relationship between the larva and Ae. aegypti mosquito. 100 % of participantes recognized tires to be a breeding for mosquitoes. 85.7% believed fever to be the most common symptom. 83 % reported accessing the health post to cure the disease. 90.8 % throw out unusable tires as if they were garbage. Conclusion In the population studied, there is good awareness of dengue and its vector. Nevertheless, there are problems related to attitudes and prevention practices.

La contaminación de la canal con E. coli O157:H7, agente etiológico de la Enfermedad Diarreica Aguda (EDA), durante el sacrificio es la ruta primaria para la contaminación de la carne picada de vacuno. El objetivo del presente estudio fue determinar la prevalencia de E. coli biotipo 1 genérico y E. coli O157:H7 en bovinos sacrificados en plantas de beneficio del departamento del Atlántico. Se analizaron 224 canales de bovino provenientes de plantas de beneficio de cuatro municipios. Las muestras fueron procesadas en el Laboratorio de Salud Pública del departamento del Atlántico. Se determinó E. coli O157:H7 por el método VIDAS UP E. coli O157 (incluyendo H7) (ECPT) y E. coli biotipo 1, usando agar TBX (Oxoid), método ISO 16649-2:2000. La prevalencia de E. coli O157:H7 fue de 0.45% y de E. coli biotipo 1 genérico fue de 0.89% en muestras con recuentos de E. coli biotipo 1 >100 UFC/cm2. En 54% de las canales con presencia de E. coli, las concentraciones oscilaron entre 1 y 758 UFC/cm2. Se concluye que la prevalencia de E. coli O157:H7 encontrada fue baja (0.45%); sin embargo, indica presencia de esta cepa patógena en la zona, por lo que se requiere fortalecer la vigilancia para expendios y distribuidores.
