RESUMO
Foram testados 543 escolares do Estado da Guanabara, Brasil, na faixa etária de 12 a 14 anos, quanto à hipersensibilidade tuberculínica ao PPD-Rt 23 e ao PPD-B.
Confirmou-se a alta prevalência de sensibilidade às tuberculoproteínas em crianças, obtendo-se 33,65% de reatores fortes ao PPD-Rt 23. Da população estudada 85,63% reagiu ao PPD-B, sendo que 6,26% apresentou reação maior a esta tuberculina que ao PPD-Rt 23, sugerindo uma hipersensibilização pelo bacilo Battey, ou outra microbactéria mais relacionada antigenicamente a esse microrganismo que ao Mycobacterium tuberculosis.
SUMMARY
The tubberculin hypersensitivity to PPD-Rt 23 and PPD-B was tested on 543 children, 12 to 14 years old in “Estado da Guanabara”, Braiil.
The sensitivity to tuberculin proteins was found high. About 33,65% of the children showed strong reactions to PPD-Rt 23 in about 6,26% of the children population, what suggests a hypersensitivity due to the Battey bacillus or another mycobacteria more antigenically related with this microorganism than the M. tuberculosis.
