Reactions of Rabbits to Non-hemolytic Streptococci
1. Accompanying and following the evolution of a secondary reaction in the skin of rabbits after inoculation with suitable doses of certain non-hemolytic streptococci there quickly develops a general state of hypersensitiveness or allergy towards these streptococci. 2. This state is made evident by ophthalmic reactions following corneal inoculations, by much increased reactivity of the skin fol...
متن کاملREACTIONS OF RABBITS TO NON-HEMOLYTIC STREPTOCOCCI. II. SraN
In previous papers it has been shown (1, 2) that rabbits inoculated in practically any manner, except intravenously, with sufficiently large doses of certain non-hemolytic streptococci developed a condition of tissue hypersensitiveness. This was made evident by the occurrence of secondary reactions at the site of the primary inoculation, by the presence of corneal sensitivity after a certain pe...
متن کاملReactions of Rabbits to Non-hemolytic
In previous communications (1) we reported the phenomenon of secondary reaction to certain strains of green streptococci. Briefly this consists of an inflammatory reaction which appears about the 8th to 10th day after intracutaneous inoculation of rabbits with these microorganisms and at a time after the primary reaction has receded. Because we were unable to obtain the reaction in any species ...
متن کاملThe Skin Response of Rabbits to Non-hemolytic Streptococci
An attempt has been made to interpret on the lines of the Arthus phenomenon the secondary reaction which follows the intradermal inoculation of certain non-hemolytic streptococci into rabbits; but evidence in support of this interpretation of the reaction has not been obtained. The facts make it seem probable that if this secondary reaction is due to a hypersensitive state it must be one more c...
متن کاملThe Conversion of Hemolytic Streptococci to Non-hemolytic Forms
From one strain of hemolytic streptococcus three forms were isolated, which produced three different degrees of hemolysis on the surface of blood agar in the presence of oxygen. The original form was moderately hemolytic; the glossy variant was more hemolytic than the original form; and the third form, obtained by passing the original culture through mice, was non-hemolytic. Under anaerobic con...
