Estudio de bacterias causantes de infecciones intestinales en productos orgánicos en los mercados de Riobamba

There is a morbidity and mortality increase worldwide, due to the contaminated food ingestion, so the objective of this study is to identify pathogenic bacteria for man, isolated from organic products sold in markets in the city of Riobamba, Chimborazo, Ecuador, and determine the antimicrobial susceptibility and resistance. It is a descriptive, transversal and field work. The products were purchased On site, the physical conditions of the samples and hygiene data in the markets were recorded using the observation sheet. Gender and species identification tests were applied in the collected products, using conventional methods and the Kirby Bauer diffusion technique to measure susceptibility and resistance. The most isolated family was Enterobacteriaceae (79.00%), represented by Citrobacter diversus, Citrobacter amalonaticus, Citrobacter freundii, Enterobacter aerogenes, Enterobacter cloacae, Klebsiella pneumoniae, Klebsiella oxytoca, Escherichia coli, Salmonella sp, Proteus vulgaris alvei; followed by Streptococcaceae (21.00%), as the only isolated Gram positive, the genus Enterococcus. All the isolates regarding to antimicrobial activity showed good sensitivity and did not show resistance mechanisms. It is concluded that the organic products sold in these markets are contaminated with bacterial population, this is caused by some failure from harvest to sale chain and becomes a risk to human health, due to the increase in enteropathogens present. We recommended to promote educative lecturers on hygienic-sanitary measures to avoid diseases that cause both personal and government economic expenses.
