Abstract:
Background: Acute lower respiratory tract infection, mainly pneumonia, were the main reasons cause death for children under 5 years old. Objectives: Determine the isolated rate of bacteria inpatients under 5 years old with acute lower respiratory tract infection in Ha Noi and antibiotic resistance of pneumococcal isolated form patients. Subjects and method: Patients under 5 years old with acute lower respiratory tract infection in National hospital of pediatrics and Bach Mai hospital from 01/2002. Using quantitative culturedand PCR method. Results: Out of total 164 patients with lower respiratory tract infection, there were 91 diagnosed pneumonia by chest X-ray, 73 cases of acute bronchitis. 73,6% of the pneumococcal isolated were penicillin resistance (gPRSP) with different genes such as pbp 1a+2x+ab. Most of the S.pneumoniae strains were serotype 19F or 23F. There were no statistic differences by comparison charactersistics of weight, vessel, subclinical symptoms such as: dissolved oxygen level (S\xac\xacp\xac\xac\xac\xacO\xac2\xac), the amount of leucocyte in blood. However, temperature of pneumonia patients was higher than bronchitis patients, breathing of pneumonia patients was also faster than bronchitis patients. Isolated bacteria with amount \ufffd?106 cfu/ml was H.influenzae, S.pneumoniae and Moraxell catarrhalis in pneumonia group, bronchitis group was 28,8% and control group was 17,1%. Conclusion: Penicillin, erythoromycin and co-trimoxazole resistance rate of S.pneumoniaein patients with acute lower respiratory tract infection was high. Quantitative cultured method has prognostic value in diagnosis pneumonia.
