Among children under two years of age, the proportion of cases due to nonsusceptible strains fell after vaccine licensure but then increased in 2004, such that no change overall was seen between 1999 and 2004 for most of the antibiotics tested (). In this age group, the proportion of isolates with intermediate resistance to penicillin was 12.8 percent in 1999, 10.7 percent in 2000, 14.0 percent in 2001, 7.4 percent in 2002, 10.8 percent in 2003, and 18.4 percent in 2004; the prevalence of high-level resistance was 26.2 percent, 26.4 percent, 21.3 percent, 13.2 percent, 13.2 percent, and 19.1 percent, respectively. The proportion of isolates nonsusceptible to one or more antibiotics did not differ significantly between 1999 and 2004 either among children under two years of age (52.5 percent and 51.7 percent, respectively; P=0.87) or among children two to four years of age (43.5 percent and 40.0 percent, respectively; P=0.61). Individual serotypes were as likely to be resistant in 2004 as they were in 1999 (). In 2004, a single serotype, 19A, accounted for 35 percent (51 of 147) of all penicillin-nonsusceptible strains among children under two years of age, as compared with only 2 percent (13 of 711) in 1999.
