RESUMO
The cellular immune response of twelve patients from the Brazilian Amazon basin with lobomycosis were assessed. Delayed skin reaction to bacterial and fungal antigens, skin allograft rejection, and sensitization to dinitrochlorobenzene were studied. Ninety-two percent of the patients were not reactive to dinitrochlorobenzene after sensitization; skin allograft rejection occurred in an average of 17 days. Delayed skin reaction to streptococcal, staphylococcal, trichophytin and candida antigens was negative in the majority of the patients. Reactivity to mycobacterial antigens, however, was very high. The results suggest that patients with lobomycosis are partially cellular immunodeficient.

The prevalence of anemophilus fungi was studied in three small towns located at the Brazilian border with Colombia and Venezuela (a hot and humid zone) during the month of July. On a single collection carried out in different spots, colonies were cultivated which could be attributed to eighteen different species of anemophilus fungi with predominance of Mucor (64%), Candida (55%), Rhodotorula (38%) and Penicillum (38%). The alternaria species, a very potent airbone allergen, was found only in one of the three collection spots with high prevalence of respiratory tract allergies.

A study was made of twenty-two biopsies of achromic lesions of Tikuna Indians, carriers of tertiary pinta, inhabitants of the Umariuassu island, on the Peruvian border, ten of the subjects had been treated two years previously with a single dose of penicillin. The histopathological picture was similar for both groups. In most cases (86.36%) slight hyperkeratosis was found on the epidermis, as well as acanthosis (18.18%), with atrophy in only two cases (9.09%). In all cases there was a reduction of the melanin of the basal layer. The inflammatory lymphocyte infiltrate was predominantly perivascular (88.18%). There wasn't any endothelial swelling.

A microbiological study was performed in the adult population of tier Brazil-Colombia, a very damp place with warm weather. It was observed a higher prevalence of P. versicolor (41.5%) and candidiasis (28.09%), followed by P. hortai and E. floccosum. The T. Tonsurans was the principal agent of the trichophitics of the hair. It's a higher prevalence of superficial mycosis was observed in the male.

Realizaram-se estudos micologicos em escolares nos vilarejos da fronteira Brasil-Colombia em julho de 1978, dentro da floresta amazonica. Observaram-se prevalencia da pityriasis versicolor em escolares de Ypiranga e Vila Bittencourt e de Piedra Negra em escolares de Cucui, seguidas da tinea capitis por Trichophyton tonsurans. Analisou-se a predominancia das micoses superficiais no sexo feminino
