Phages-Adsorption-Test for Differentiation of Genus: Brucella

Abstract

Brucella-phages-adsorption test on killed (70°) cells of all types of Brucella in the pure “S” phase has orientating value for determination of the Genus: “Brucella”. Brucella abortus “S” strains are in 100% positive in this test. Brucella melitensis “S” strains are in 83% positive and in 17% weakly positive. Brucella suis “S” strains are in 100% positive. Brucella atypica “S” strains are mostly positive. All types of Brucella in “R” phase are negative in this test. This experiment is important from point of view of general systematics of bacteria and for the explanation of phage—specific receptors in the “S” and “R” phase. © 1965, Walter de Gruyter.
