ANDUEZA-LEAL, Félix Daniel et al. Biodiversidad bacteriana en aguas de balnearios mineromedicinales de Ecuador y Venezuela. Figempa [online]. 2023, vol.15, n.1, pp.56-77. ISSN 2602-8484.  https://doi.org/10.29166/revfig.v15i1.4368.

The medicinal mineral waters in Ecuador and Venezuela have been used for centuries as medicines by the population of these countries. However, bacterial biodiversity is poorly understood. Therefore, the objective of the work was to know the bacterial biodiversity in the medicinal mineral water’s spas in Ecuador and Venezuela. Water samples were taken at various points in each spa. The microbiological studies were carried out following the schemes proposed by MacFaddin, complemented with the biochemical tests of the API and Microgen gallery. In the waters of the spas of Ecuador, 284 colonies of the genera Acidovorax, Acinetobacter, Actinomyces, Aeromonas, Alcaligenes, Bacillus, Brevibacterium, Brevundimonas, Budvicia, Burkholderia, Citrobacter, Corynebacterium, Edwardsiella, Ewingella, Flavobacterium, Kurthia, Micrococcus, Moraxella were identified. Proteus, Pseudomonas, Psychrobacter, Ralstonia, Staphylococcus, Vibrio, Yersinia, Yokonella and Xenorhabdus. In the waters of the Venezuelan spas, it was possible to identify 158 colonies of the genera Aeromonas, Alcaligenes, Bacillus, Brevundimonas, Burkolderia, Chromobacterium, Citrobacter, Comamonas, Edwardsiella, Enterobacter, Klebsiella, Kluyvera, Moraxella, Plesiomonas, Proteus, Pseudomonas, Ralstonia, Shewanella, Staphylococcus, Weeksella and Vibrio. A clear predominance of Gram-negative bacteria of the Gamma proteobacteria class was observed.
