Resumo
The AA. carried out experiments in the leprosarium São Roque, State of Paraná, South Brazil, to verify if the cattle tick Boophilus microplus could be experimentally infected in lepers, which was true. The AA. Tried also to be ascertained if Boophilus microplus and Amblyomma cajennense could change of hosts during their feedings which was true, both ticks continue feeding, the last species for many days, after being transferred from one to another leper. The junior A. describes in full their experiments and also a dermatites caused by tick bites. The senior A. brought to Rio de Janeiro most of the infected ticks for examination, which revealed a very high positivity. He smeared the sediments of lots of both species of ticks in Loewenstein medium and after a variable periode of incubation at 37° C. he obtained four new samples of cultures of acid-fast organisms, two from Amblyomma cajennense and two from Boophilus microplus. These cultures are being studied and will be inoculated into laboratory animals. The senior A. inoculated new batches of white rats with sediments of many ticks infected in lepers. Various hypotheses of both previous notes upon the subject now are verified facts. The A. is accumulating facts to draw the conclusions in the future. He also suggested the leprosy workers in the interior of the country to cooperate with him in such important studies, specially in the habitat of lepers in the rural zones of various States.
