Detection of multiple serotype carriage is important in understanding pneumococcal epidemiology. We compared random selection of 4 pneumococcal colonies per swab with selection by colony morphology. Multiple serotypes were detected in 20% of 98 swabs; 14% by morphology and 17% by random selection. Selection by morphology was more efficient per colony, but underestimated the true rate of multiple carriage.
