Resistencia Bacteriana en infecciones de vías respiratorias superiores en pacientes de consulta externa en el Hospital de Especialidades San Juan- Riobamba

Abstract

It was determined the bacterial resistance in infections of upper respiratory tract in patients of outpatient in specialties Hospital San Juan, from the city of Riobamba, Chimborazo province. The method was sowing and isolation of microorganisms, and then they were carried out biochemical tests for identification of the germ. Sensitivity and resistance tests were carried out through the antibiogram, by diffusion with discs impregnated with anti biotics. Determined that major infections that come the patients of outpatient area of Otolaryngology are chronic sore throat with 36% and chronic pharyngitis with a 64% diseases caused in a 39,6% by Staphylococcus aureus , a 37,7% for b - hemolytic Streptoco ccus group A. The chronic sore throat is mostly caused by 63% by Streptococcus b - hemolytic group A, and chronic pharyngitis is caused in higher percentage by Staphylococcus aureus with 44% of the cases. The microorganisms that cause these infections are 71 % lincomycin | and ampicillin - resistant and 66% are resistant to amoxicillin, 43 to 56% are resistant to azithromycin, erythromycin, penicillin, cephalexin, but they are 100% sensitive to cefotaxime. It concludes that upper airways infection - causing microorganisms have greater resistance against antibiotics beta - lactams and lincomycin. It is recommended the culture and antibiogram prior to treatment and avoids self - medication.
