LOCAL PASSIVE ANTIBACTERIAL IMMUNITY AGAINST EXPERIMENTAL SKIN DIPHTHERIA IN RABBITS

Flagella-induced immunity against experimental cholera in adult rabbits.

The adult rabbit ligated ileal loop model was used to evaluate the prophylactic potential of a crude flagellar (CF) vaccine produced from the classical. Inaba strain CA401. A greater than 1,000-fold increase in the challenge inoculum was required to induce an intestinal fluid response in actively immunized adult rabbits equivalent to that produced in unimmunized animals. Similar protection was ...

Passive Antibacterial Immunization in Conjunctival Diphtheria in Guinea Pigs.

In a previous paper (Hirose et al., 1962) it was reported that guinea pigs highly immunized against a bacterial suspension of Corynebacterium diphtheriae resisted to a challenge by the conjunctival method (Murata et al., 1959) with a toxinogenic virulent strain without even traces of antitoxic immunity, while a passive transfer of the immunity failed. The reason for this failure may have been d...

Local Passive Immunity in the Skin of Rabbits to Infection with (1) a Filterable Virus, and (2) Hemolytic Streptococci

Small areas of skin infiltrated with immune serum proved refractory to the injurious action of a filterable rabbit virus inoculated 24 to 48 hours later. Infiltrations of normal serum did not appreciably protect the skin against the virus. The local protection afforded by the infiltrations of immune serum appears to constitute an example of local passive immunity. Small areas of skin infiltrate...
