Experimental infection of Macaca mulatta monkeys with Lednice (Yaba 1) virus.
Macaca mulatta monkeys were inoculated with Lednice (Yaba 1) virus strain 6118. The animals developed no clinical signs and the body temperature and values of complete haematological examination remained within normal limits. In spite of positive immunofluorescence in regional lymph nodes, no virus could be recovered from them by passages in mice. Viraemia was not demonstrated. The antibody response was directly proportional to the amount of virus inoculated, i.e. it was significant after a higher virus dose or after repeated inoculation. The results obtained are discussed in respect of and in comparison with serological findings in man.
