RESUMO
Escherichia coli BJ4, a rat isolate, was used to examine the growth and differentiation of the microorganism in its natural habitat, the intestine. Growth of E. coli BJ4 in the large intestine of streptomycin-treated mice was compared with its growth in laboratory media. By a number of methods, it was shown that E. coli BJ4 differentiates, during growth in the intestine, into two distinct populations, one that has the characteristics of the laboratory-grown strain and one that appears as a coccoid cell. Furthermore, it was shown that there is a natural selection for the coccoid-type cell in the intestine, while in laboratory media growth of rod-shaped E. coli BJ4 is enhanced.
