Abstract

A total of 129 isolates of Streptococcus pneumoniae from nasopharyngeal specimens was typed by the Neufeld reaction using diagnostic antipneumococcus sera produced at Statens Seruminstitutt, Denmark. Most isolates (87.6%) reacted with the serum pools B (41.9%), H (34.9%), and D (10.8%) comprising the types 3, 6, 8, 9, 11, 13, 14, 15, 16, 19, 23, 28, 36 AND 37. Only 12.4% of the isolates belonged to the remaining six serum pools. Among the strains reacting with serum pools B, D, and H, the most frequently encountered types were 6 (33%), 19 (18%), 3 (13%), 14 (11%), 23 (11%) and 15 (7%). Among these six types, only type 15 is not included in the available pneumococcal vaccine.
