[Quantitative parameters of the length of time of Vibrio eltor survival on household objects]

On household articles contaminated with protein-containing excrements (as in the stool of cholera patients) V. eltor survive 4.6 times longer than on those contaminated with excrements without protein (as in the stool of vibriocarriers ). This is due to a lesser initial dose of vibrios and the absence of protein in the excrements of vibriocarriers . These differences in the survival time of V. eltor on household articles suggest that objects contaminated with the excrements of cholera patients are epidemiologically more dangerous than those contaminated with the excrements of vibriocarriers . The quantitative determination of the survival time of vibrios on household articles indicates that, probably, these articles merely play the role of intermediate factors in the transfer of V. eltor in the foci of cholera.
