Antimicrobial susceptibility profile for escherichia coli in urine culture of patients from a home health program

Abstract: There is a high frequency ofE.coli genitourinary infections in patients of home care programs. The susceptibility profile of infectious agents in such patients needs to be studied toestablish effective preventive measures and treatment. Objective: We aimed to evaluate the profile of antimicrobial susceptibility of the E. coli isolated from patients assisted by a Home Care Program of health. Methods: Home visits were conducted and 112 urine samples were collected. Bacteria were isolated and identified through specific tests for each bacterial class. Susceptibility tests were performed for various classes of antibiotics. Results: Of the 112 cultures tested, 61 (54.5%, CI = 45.28 to 63.72) exhibited growth of an infectious agent, 46 from males (75.4%, CI = 67.42 to 83.38) and 15 from females (24.6%, CI = 16.62 to 32.58). Of the 61 cultures, 17 (27.87%) showed the presence of E. coli. Antibiogram analysis revealed that of the 17 samples tested 14 showed bacterial multiresistance. Conclusion: This was the first report that linkedbacterial multiresistance of urine cultures from patients to the home health program. Further studies are needed to define the genotypic associations and the resistance mechanisms of these agents.
