Background: The number of erythromycin-resistant has significantly increased around the world. The present study aimed to determine the serotype distribution and molecular epidemiology of the erythromycin-resistant (ERSP) isolated from patients with invasive disease.
Methods: A total of 44 isolates were tested for susceptibility to several antimicrobial agents.
Introduction: Encapsulated strains cause high morbidity and mortality, mainly in countries with no pneumococcal conjugate vaccines (PCVs) immunization program. This study investigated the epidemiological changes of isolates including serotype distribution and antimicrobial susceptibility in Tehran, Iran.
Methods: A total of 80 samples were collected from patients admitted to Shariati hospital over two periods.
