Different formulations of trivalent oral poliomyelitis vaccine were tested, in order to obtain better thermostability, reduce corrosion of machinery and improve production costs. Magnesium chloride, sucrose, arginine and 199-Hank's medium were used in the formulations. The most appropriate formulation was a mixture of MgCl2 and arginine, which was highly thermostable, and had low production costs. The low corrosive formulation was rejected, due to low thermostability on storage

The occurrence of intestinal parasites, its relation with the transmission mechanism of HIV, and the clinical state of the AIDS patients, were analyzed in 99 Group IV patients (CDC, 1986), treated at "Hospital Universitário Pedro Ernesto" (HUPE), between 1986 and 1988. The group consisted of 79 (79.8%) patients whose HIV transmission mechanism took place through sexual contact and of 16 (20.2%) who were infected through blood. Feces samples from each patient were examined by four distincts methods (Faust et al, Kato-Katz, Baermann-Moraes and Baxby et al.). The moste occuring parasites were: Cryptosporidium sp., Entamoeba coli and Endolimax nana (18.2%), Strongyloides stercoralis and Giardia lambia (15.2%). E. histolytica and/or E. hartmanni (13.1%), Ascaris lumbricoides (11.1%) and Isospora belli (10.1%). Furthermore, 74.7% of the patients carried at least one species. Intestinal parasites were found in 78.5% of the patients who acquired the HIV through sexual intercourse and in 56,3% of those infected by blood contamination. The difference, was not statistically significant (p > 0.05). In the group under study, the increase of the occurrence of parasitc infections does not seem to depend on the acquisiton of HIV through sexual contact. It appears that in developing countries, the dependancy is more related to the classic mechanisms of parasites transmission and its endemicity

Estudo retrospectivo anatomopatologico de um caso de meningoencefalite amebiana primaria ocorrido no Rio de Janeiro em 1972, em paciente jovem e saudavel. O aspecto morfologico a microscopia otica e eletronica demonstrou tratar-se de N. fowleri.Na pesquisa epidemiologica, atual do poco que forneceu agua, veiculo da doenca, para a piscina nao-tratada, nao se isolaram cepas patogenicas de amebas de vida livre

Foram isoladas amebas dos generos Vahlkampfia, Glaeseria, Acanthamoeba, Filamoeba, Amoeba, Platyamoeba e Hartmanella de dez diferentes marcas de agua mineral engarrafadas, servidas no Rio de Janeiro, RJ (Brasil). Somente uma das marcas foi negativa para protozoarios, enquanto que de todas as outras foram isoladas amebas de vida livre. O significado desses resultados e discutido como um indicador de qualidade da agua mineral usada comercialmente, destacando-se o fato de que alguns desses microorganismos sao potencialmente patogenicos
