ABSTRACT
The indirect hemagglutation test (IHT) indicated that rotaantigen infection of dairy foods (DF) selected at the milk processing shop in the year of high morbidity due to rotavirus infection (RVI) averaged 12.4%. Laboratory monitoring of DF sold in the year of relative low morbidity could establish that the rate of their rotaantigen contamination averaged 4.8%, as evidenced by IHT; polymerase chain reaction was positive in 19.3% of cases. Comparison of annual trends in the detection rate of rotaantigen in DF and RVI morbidity revealed that there was an increase in DF rotavirus contamination in the cold period of a year, following the seasonal activation of an epidemic process.

We report results on event-by-event fluctuations of transverse momentum, Phi(p(t)), in pi(+)p and K(+)p collisions at 250 GeV/c. For the first time, their dependence on rapidity region, transverse momentum acceptance, multiplicity, mean transverse momentum per event, and on the correlation between transverse momentum and multiplicity are systematically presented. The results are compared with those from the PYTHIA Monte Carlo generator. The fluctuations under the same acceptance cuts as used in current heavy-ion experiments are also presented.
