[Echinococcus granulosus infection (hydatid cyst): a case report]. / Infección por Echinococcus granulosus (quiste hidatídico): reporte de un caso.

Larval Echinococcus granulosus infection (hydatid cyst) was reported in a 10 years-old Ukranian girl. The clinical manifestations were slight since she only complained of frequent abdominal pain. The diagnosis was made by ultrasound and immunoenzymatic detection of antibodies to Echinococcus (ELISA). Antibody titers were 1/800. She was repeatedly treated with albendazol, and she managed to recover while the size of her cyst was reduced.

Preliminary assessment of the safety and immunogenicity of a new CTXPhi-negative, hemagglutinin/protease-defective El Tor strain as a cholera vaccine candidate.

Vibrio cholerae 638 (El Tor, Ogawa), a new CTXPhi-negative hemagglutinin/protease-defective strain that is a cholera vaccine candidate, was examined for safety and immunogenicity in healthy adult volunteers. In a double-blind placebo-controlled study, no significant adverse reactions were observed in volunteers ingesting strain 638. Four volunteers of 42 who ingested strain 638 and 1 of 14 who received placebo experienced loose stools. The strain strongly colonized the human small bowel, as evidenced by its isolation from the stools of 37 of 42 volunteers. V. cholerae 638, at doses ranging from 4 x 10(7) to 2 x 10(9) vibrios, elicited significant serum vibriocidal antibody and anti-Ogawa immunoglobulin A antibody secreting cell responses.
