MARIN MENDEZ, Mayelin et al. Characterization of bacterial agents isolated in diseases outbreaks transmitted by foods. MEDISAN [online]. 2020, vol.24, n.2, pp.235-251.  Epub Apr 24, 2020. ISSN 1029-3019.


Diseases transmitted by foods are produced due to ingestion of a food, including water that can be contaminated by diverse agents.


To characterize the bacterial agents isolated in diseases outbreaks transmitted by foods.


An observational, descriptive and cross-sectional study of 100.0 % of the diseases outbreaks transmitted by foods in Santiago de Cuba, from January, 2018 to December, 2019 was carried out, for which samples of foods and stools were selected. The characterization of the isolated bacterias was based on the results of growth and other biochemical-metabolic tests. Results of the isolation and confirmation of agents identified in each one of the outbreaks from the samples mentioned above were used. Among the analyzed variables we can mention: number of outbreaks, samples of foods, samples of stools and results of biochemical and metabolic tests.


An isolation of bacterial agents was obtained in 100.0 % of foods samples. There was a higher frequency of Gram negative bacterias (82.0 %) and the lower corresponded to Gram positive microorganisms (18.0 %). Salmonella D was the most frequent microorganism.


This result represents an instrument for the etiological diagnosis of diseases outbreaks transmitted by foods in Santiago de Cuba.

Keywords : diseases transmitted by foods; epidemiological markers; bacterial agents; stool culture; culture means.
