[Phlebotominae: vectors of leishmaniasis in the provinces of Santa Fe and Entre Ríos, Argentina].

The transmission of tegumentary leishmaniasis (TL) has increased in 9 provinces of Argentina since 1985. Santa Fe and Entre Ríos did not record in this period autochtonous probed cases: however, an epidemic outbreak took place in 2003 in Bella Vista, Corrientes, located in an area with ecological continuity and contiguous to both provinces. In order to evaluate the potential risk of transmission of LT, Phlebotominae were captured at locations close to and southern from Bella Vista during February 2004.

[Infection outbreak due to resistant Enterococcus faecium to glycopeptides in a Hospital of Rosario, Argentina].

Enterococci causes serious illness in immunocompromised patients and in severely ill, hospitalized patients. They are commonly isolated from the human gastrointestinal tract, and resistance to vancomycin has increased in frequency during the past few years. We report three cases of nosocomial vancomycin resistant Entrococcus faecium (VRE) infections from September to December of 2000.

[AIDS and pregnancy: a case of mother-child transmission].

We report the case of a 4 month old baby in an advanced stage of HIV infection with AIDS according to the CDC definition. The HIV-infected mother was sexually promiscuous and a drug addict. The timing and route of the infection are speculative.
