Dynamics of Pneumococcal Nasopharyngeal Colonization During the First Days of Antibiotic Treatment in Pediatric Patients.
Pediatr Infect Dis J 17: 880-885, 1998.
It is well-known that previous use of antibiotics leads to formation of resistant S pneumoniae in the nasopharynx of children. This study demonstrates that the appearance of resistant S pneumoniae in children treated with penicillin and ampicillin produces resistant strain in 3-4 days. This may contribute to the spread of resistant pneumococci.

Methicillin-Resistant and Borderline Methicillin-Resistant Asymptomatic Staphylococcus aureus Colonization in Children without Identifiable Risk Factors.
Pediatr Infect Dis J 18:410-414, 1999
Several recent reports have described the occurrence of community acquired MRSA in patients without risk factors. This study demonstrates the changes in the epidemiology of MRSA in the community.
Carriers were isolated in children who do not have MRSA risk factors and who do not come in contact with MRSA or health care settings with the community. We can say that the carriage rate in MRSA in the community is low but not zero.
