Serologic Types of Pseudomonas Aeruginosa Based on Heat-Stable 0 Antigens: Correlation Of Habs' (European) and Verder and Evans' (North American) Classifications

Serological and Pyocine Types of Pseudomonas aeruginosa from Various Sources

“…In Japan, other investigators [9,11] have studied the serological types of P. aeruginosa by employing either the Verder and Evans' or Habs' classification. Their results and our results reported in this paper suggest that the distribution of the P. aeruginosa serotypes in Japan is substantially the same as that in other countries [14,19,23].…”

“…In addition, the 07a, 7b antigen was proven to have no relationship to the 07a, 7c antigen. Recently, Muraschi et al [14] have reported similar experimental results, and consider the Verder and Evans 0 antigen 07a, 7b as 03 because it had no relationship to 07a, 7c. We frequently encountered P. aeruginosa belonging to this 0 group and the occurrence of this 0 group in other areas of Japan is evident.…”

“…Those studies, including early ones, are reviewed by Verder and Evans [19], Hobbs and Cann [8] and Muraschi et al [14]. Today, two different systems of serological classifications of P. aeruginosa are in current use.…”

“…The other, established independently by Verder and Evans [19], proposed an antigenic schema for P. aeruginosa composed of 35 serotypes constructed by combinations of ten 0 antigens and eight H antigens. Muraschi et al [14] has performed comparative studies on the 0 antigenic relationships between these two different serological groups, and because of their efforts the strains of P. aeruginosa used in this study can be compared by both schemes. Undoubtedly, this knowledge facilitates epidemiological investigations of this microorganism throughout the world.…”

“…This included the 13 0 type strains of Verder and Evans, and in addition 3 of Habs' 0 type strains, 04, 07 and 010. The latter 3 were included in our group of serological test strains, since, according to Muraschi et al [14], they had no counterpart in the Verder and Evans group of 0 types.…”
