Enteric infections in childhood are estimated to be a primary cause of illness and death in the third world and Rotaviruses play a very important role in acute nonbacterial diarrheal enterocolitis. The Authors analyse the latest results of the direct investigation of the virus in the feces by ELISA method. The improvements in diagnostic techniques and the new knowledges about Rotaviruses and their pathogenic power acquired during the last decade have made it easier to know the consequences of Rotavirus infections particularly in the poorest countries, with very bad sanitary conditions. Much attention has therefore been paid to the study of dietetics and immunoprophylaxis in order to find the most suitable cure. At present only some vaccines of animal origin are available that many Authors consider to be harmless, and that, might hopefully be employed in the third world countries.

[Old and new pathologies proposed by epidemiology].

The results of a study made in the areas of Central Italy on a random community on the significant presence of cases with seroantibodies against Campylobacter, Yersinia, Legionella Pneumophila, Francisella Tularensis and Rotavirus confirm the hypothesis on the presence in the territory of microorganisms responsible. These positivities in man are not only single but also contemporaneous for at least two microorganisms. Hence the hypothesis of the presence in the environment (animals, soil, surface waters) of the microorganisms (Campylobacter, Yersinia, Legionella Pneumophila, Francisella Tularensis, and Rotavirus) responsible for the zoonoses of interest for man.

[From the historical background of Toxoplasma gondii to the sero-immunological interpretation of the 30-yr results of a longitudinal study of newborn infants until 96 months of age].

The Author's study ranges from the historical background of Toxoplasma gondii to our current biological knowledge and the role of Toxoplasma gondii in pathology and human infection. The Author has considered the diagnosis--always problematic from the interpretative point of view--and, on the basis of his own long and extensive research, suggests the usefulness of a comparison with the results obtained from the dye test findings observed in longitudinal surveys of new born up to a maximum age of 96 months. The Author believes that these results can represent an element of comparison for the purpose of prognosis, therapy and prophylaxis, and above all, in sedation to combat anxiety states, and banal preoccupations.
