Abstract:
In the last decade there has been a growing increase in antimicrobial resistance, this has been due to bad practices and excessive use in the clinical and agricultural area. Aeromonas species cause infections in fish and shellfish, causing furunculosis, causing large economic losses in fish farms. In humans Aeromonas causes gastroenteritis and infections in wounds and soft tissues. According to the WHO Aeromonas is classified as a priority pathogen for the development of new strategies for its control. Bdellovibrio is a predatory bacterium that has a wide range to attack Gram-negative bacteria even greater than some phages, which represents a great potential for the control of pathogenic bacteria. In this study, ten bacteria of the genus Bdellovibrio were isolated from environmental samples (soil, water and feces of mammalian animals), all were identified within the genus Bdellovibrio, through partial sequences of the 16S rRNA gene. Their predation efficiency against Aeromonas strains of clinical and environmental origin was evaluated. All Bdellovibrio spp. isolates showed efficiency in preying on Aeromonas species. In the predation efficiency results, Bdellovibrio isolates showed a reduction in the population of Aeromonas strains after 5 to 16.5 h of their inoculation.
