Abstract
Clinical features of respiratory infection in the elderly with penicillin insusceptible (31 cases) and resistant (7 cases) Streptococcus pneumonia (PSSP/PRSP) are compared to those with penicillin sensitive S. pneumoniae (PSSP) (29 cases). Incidence of bacteremia and pneumonia was higher in the PSSP group. PISP/PRSP tend to be isolated from patients with bronchitis underlaid with chronic pulmonary disease without statistic significance. Efficacy of the penicillins and 1st and 2nd generation cephem was satisfactory except in only one case of pneumonia with PISP which needed an alternative choice to the 3rd generation cephem. Now a day the degree of resistance is not so high and the available antibiotics are sufficient for the treatment of pneumococcal infection in the elderly patients. However, the wide use of oral cephems and certain new quinolones which do not have enough activity against Streptococcus pneumoniae may increase resistance. In which case, continuous surveillance and clinical caution against this resistant strain is necessary.
