Multidrug-Resistant Hospital Bacteria: Epidemiological Factors and Susceptibility Profile.

Increase in antimicrobial resistance to antibiotics is the product of the evolution and natural adaptation of microorganisms through mutations and genetic recombination caused by the indiscriminate use of antibiotics and the ineffective control and prevention of infection. The current study analyzes the profile of multiresistant hospital bacteria in two hospitals in Pelotas, state of Rio Grande do Sul, Brazil. Over the course of 4 months, patient's gender and age, hospital accommodation type, and sample site were evaluated.
