Marked differences in pneumococcal carriage and resistance patterns between day care centers located within a small area Academic Article uri icon


  • Carriage rates of Streptococcus pneumoniae and their antibiotic resistance, capsular types, and genetic patterns were studied among 264 children aged 12‐35 months attending 8 day care centers located within a 2.5-mile radius in the same city. Nasopharyngeal cultures were obtained within a 2-month interval from all 264 children. Significant differences in each of the studied characteristics were found between day care centers, and each day care center had a unique pattern of the carried pneumococci. Our findings show that day care centers are independent microenvironments and emphasize their role in the transmission and augmentation of antibiotic-resistant S. pneumoniae in the community. Streptococcus pneumoniae is an important cause of morbidity and mortality in all societies [1]. The spectrum of illness caused by the pneumococcus is a reflection of its ability to survive in various ecological niches in the human body. S. pneumoniae resides in the nasopharynx, most commonly without adverse
