Abstract In the 77 reference strains for Klebsiella K types, there are 17 strains (22.1%) of Klebsiella planticola , 6 strains (7.8%) of Klebsiella oxytoca , 1 strain (1.3%) of Klebsiella terrigena , and 53 strains (68.8%) of Klebsiella pneumoniae . The species K. planticola , which was originally isolated from botanical and aquatic environments and hence thus named, was also identified at high incidence (81 strains, 18.5%) among the 439 recent clinical isolates of Klebsiella species. Among these K. planticola strains of hospital origin, 52 (64%) were isolated from sputum, 17 (21%) from urine, and the remaining 12 (15%) from other sources. The capsular types of these isolates were determined by the gel precipitation reaction. Seventy of 81 K. planticola isolates (86.4%) were typable by antisera to Klebsiella reference strains for K types and the K types of the clinical isolates distributed to 35 kinds of K types. The proportion of typable strains among clinical isolates of K. planticola was very similar to those in K. pneumoniae (87.5%) and K. oxytoca (86.0%).
