Caracterización microbiológica del aire en el casco urbano de Calceta, Manabí, Ecuador.

The presence of pathogenic microorganisms in the air has a direct effect on human health. The objective of this research was to microbiologically characterize the air in the urban area of Calceta-Manabí at different times and days. 12 data collection points were established, the sampling was carried out during July 2019; The sedimentation method in Petri dishes was used to collect samples. Nutrient agar was used for bacteria and malt extract agar for fungi. The Petri dishes were placed open at a height of 1.50 m from the ground for 30 minutes. It was found that there is a high bacterial concentration in points close to the central market; and lower fungal concentration. There is a significant difference in the frequency of monitoring, where the average concentration of CFU / m3 and UPC / m3 is higher on weekends. [ABSTRACT FROM AUTHOR]
