Bacillus spp. characterization and his intervention as a possible non-traditional etiology of chronic renal insufficiency in Tierra Blanca, Veracruz, Mexico

Environmental, socioeconomic, educational, custom, occupation, and native pathogen microbiota factors have been identified as unique etiological factors by region for chronic renal insufficiency (CRI). In the region of Tierra Blanca, Veracruz, there is a significant incidence of CRI. The objective of this research was to identify the presence of the genus Bacillus spp. and its kinetic characterization for recognition as a possible non-traditional etiology of CRI in the region. The methodology included the isolation and morphological, biochemical, molecular and kinetic characterization of strains of the genus Bacillus spp. and an analysis of factors that indicate that their presence could affect the occupational health of the population, prompting cases of CRI. The presence of Bacillus cereus (pathogenic strain for humans) was established (biochemical identification, similarity 99%, by 16S rRNA gene) in sugarcane crops, mainly in the MEX-69-290 variety, with the higher growth rate and lower lag phase, compared to the other isolates. The strains are reported as a potential danger of direct infection and a risk factor for the indirect development of CRI, in the non-traditional cause modality, in the sugarcane fields. It is recommended that committed actions be undertaken to protect and promote the health of the population.
