Observations on Pseudomonas pyocyanea

The Antigens of Pseudomonas aeruginosa Studied by the Ouchterlony Technique and Immuno-electrophoresis

“…Grouping of strains of this species on the basis of antigenic structure has also attracted much attention (Aoki, 1926;Sandiford, 1937;Gaby, 1946;Mayr-Harting, 1948;Christie, 1948 ;Munoz, Scherago & Weaver, 1949;Homma, Sagehashi & Hosoya, 1951 ;Verder & Watt, 1953;Gould & McLeod, 1960) and might be expected to provide a means for detecting minor differences between strains. Agglutination tests, however, have given rather disappointing results, partly because of diiliculties in distinguishing flagellar from somatic antigens (see for example MayrHarting (1 948) and some experiments briefly reported in the present paper).…”

A New Species of the GenusPseudomonasPathogenic for certain Reptiles

“…For example, Sanborn (1933) reported the presence of P. fluorescens on the surface of fresh halibut; this may be regarded most probably as a contam-.inant from the holds of fishing boats, nets, etc. Sandiford (1937) found that cultural characteristics listed in Bergey (1934) do not differentiate strains isolated from water from those of human origin; he regards P. fluorescent as a saprophytic form of P. aeruginosa. Because of the confusion which exists in the literature relative to descriptions, the variability which may be encountered in this genus in both morphological and cultural respects, and the scanty knowledge which exists in regard to pathogenicity, we have constantly compared the bacterium herein described with the genus type species, P. aeruginosa.…”

Study of Dissociative Behavior ofPseudomonas aeruginos

“…These authors also reported that agglutination and absorption tests failed to reveal any differences among the various strains tested. Standiford (1937) found that he could not distinguish between P. aeruginosa and P. fluorescens culturally or serologically; thus he labeled all his strains P. aeruginosa. Brooks, Nain, and Rhodes (1925) examined a group of the fluorescent microorganisms associated with plant diseases by cultural, biochemical, and serological methods.…”
