Pseudomonas aeruginosa infection: Activation of B suppressor cells which affect cell cooperation in the induction phase of contact sensitivity to oxazolone in mice.

Pseudomonas aeruginosa depresses contact sensitivity to oxazolone in mice by activating B suppressor cells within the lymph nodes that drain the site of sensitization. These suppressor cells affect the induction phase of the immune response by blocking the cooperation between 'stimulator' macrophages and 'initiator' T cells on one hand and 'recruited' T cells on the other.
