Evaluación de la sensibilidad a los antibióticos y factores de virulencia de bacterias Gram negativas aisladas de la carne de pollo que se expenden en el cantón de Ambato (Comamonas kerstersii, Aeromonas veronii, Pseudomonas aeruginosa)

Abstract

The following research work was developed in the Laboratories of the Technical University of Ambato, with the objective of evaluating the sensitivity to antibiotics and virulence factors of the following bacteria: Comamonas kerstersii, Aeromonas veronii, and Pseudomonas aeruginosa, isolated from meat of chicken that is spent in the Ambato canton. We worked with 6 samples, carrying out the management of the experiment in three phases. The statistical method used was the Kolmogorov Smirov method to determine if there is a normal distribution. Demonstrating the results, the following data: Pseudomonas aeruginosa and Comamonas kerstersii have greater sensitivity to the antibiotics used, while Aeromonas veronii showed resistance. The molecular mechanisms of resistance vary according to the type of bacteria and the antibiotic. Finally, as a defense mechanism, bacteria develop virulence factors to evade the response of the body's immune system. Keywords: Comamonas kerstersii, Aeromonas veronii, and Pseudomonas aeruginosa, sensitivity, resistance, antibiotic, bacteria, virulence factors.
