[Production of slime by coagulase-negative staphylococci as a marker of systemic infection in newborn infants].

We studied 310 strains of Staphylococcus spp. from neonates admitted in intensive care unit from june 1988 to may 1990, with the purpose of establishing a relationship between the slime production and the occurrence of sepsis. The original technique for its determination was modified; this facilitated the performance and the reading of results.

A ten-laboratory study of lomefloxacin (NY-198 or SC 47111) antimicrobial activity in Argentina.

The antimicrobial activity of a new fluoro-quinolone, lomefloxacin (NY-198, SC47111), was evaluated by standardized susceptibility testing methods at ten laboratories in Argentina. Lomefloxacin was found to be the most active drug against 1,316 recent clinical isolates compared directly to norfloxacin, co-trimoxazole, and gentamicin. Only 1.

[Neonatal Chagas disease: laboratory diagnosis during the first year of life].

This paper describes the parasitologic and serologic studies carried out during the first year of life in 721 pediatric patients born to mothers serologically positive for Chagas disease. The search for circulating trypomastigotes was performed by Strout, blood culture and/or Xenodiagnosis. In some cases, amastigotes were also detected in placenta and umbilical cord.
