Time course of nontyphoid salmonellosis in Slovakia 1957-2008

Yearly numbers of new cases of this disease, collected over one half century,were processed by uncostomed biometrical tools – testing of randomness of the time sequence using Poisson and „contagious“ distributions, cosinor regression and crosscorrelation.The older experience of these authors – cycling of the daily numbers of cases during synodic lunar cycle – has been extended to the years´ scales: cycling contemporal with the Moon nutation period was found as significant. It is another evidence for a putative effect of gravity on bacterial virulence of Salmonella. In the mean time, experiments in NASA laboratories,USA found a dangerous increase of Salmonella virulence in microgravity conditions. Practical consequencies for the medical securing of space flight crews are indicated.
