| Summary: | Os autores apresentam os resultados preliminares da relação entre o grau de contaminação pelo C. tetani e a composição química de 82 amostras da camada superficial do solo do Estado do Rio de Janeiro, colhidas ao acaso. Não encontram relação importante entre a presença do bacilo e a concentração de potássio, magnésio, fósforo, alumínio, carbono e o pH do solo. As amostras ricas em cálcio, porém, apresentaram maior positividade. Devido à heterogeneidade das amostras, possibilitando a influência de outros fatores nos resultados, os autores pretendem estudar o assunto em amostras mais selecionadas. The authors made a initial study about the relationship between the soil contamination by C. tetani and the chemical composition of 82 soil samples from the Estado do Rio de Janeiro (Brasil). C. tetani was found in 29.2 % of the samples. No relationship could be demonstrated between the presence of the bacillus and the amount of potassium, magnesium, phosphorus, aluminium and carbon (organic material), as well as the pH of the soil. The microbe was or was not found either in rich soils or in poor ones, as well as in acid, neutral or basic soils. It was found a correlation between the amount of calcium and the positivity of the bacillus. Since many factors may have influenced the results, the authors will study this subject more deeply.
