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.

Distinct increase in the incidence of this disease, observed in Central and Eastern Europe recently, was registered also in Slovak children. Nevertheless, an original finding is the significant presence of 10-11-years cycling, corresponding probably with that in the solar activity, and of 7-years cycling, known for geomagnetic activity These periodicities are superposed on an increasing linear trend, affirmed in some Western „main stream“ journals (e.g.Diabetologia) as the only pattern in this issue.

Definition and composition of blood, its function. Determination of hematocrite, erythrocyte sedimentation rate and osmotic resistance.
