متن کاملActive and Passive Immunization in Typhus Fever.
Inspection of the paleontologic history of many phyla shows that when certain members of a series of polyisomeres have been subjected to in-. creasing stresses through long periods of geologic time, they have often become enlarged, strengthened or fused with their neighbors and have thereby passed into a state of anisomerism. Thus taxonomy, paleontology, comparative anatomy, genetics, experimen...
متن کاملActive Immunization against Poliomyelitis in Monkeys
1. A combination of poliomyelitis virus and specific human serum is effective for the production of active immunity. 2. For each gram of active virus given intradermally as an emulsion, 6 cc. of human immune serum, injected subcutaneously, was required in our experiments to protect a monkey from paralysis. Some degree of active immunity was induced. 3. Immunity, without symptom of the disease, ...
متن کاملImmunity to pertussis 5 years after booster immunization during adolescence.
BACKGROUND We conducted a 5-year follow-up study on the persistence of pertussis-specific antibody and cell-mediated immunity after booster immunization of adolescents aged 11-13 years with a tricomponent acellular pertussis vaccine (Boostrix; trials diphtheria-tetanus-acellular pertussis [Tdap]-004/030). METHODS Cellular and humoral immunity to pertussis toxin (PT), filamentous hemagglutinin...
