[Salmonella gastroenteritis in children].

Introduction: The gastroenteritis (GE) by Salmonella is an important cause of disease in childhood. In Portugal an average of 456 cases per year are notified, 82% of which before the age of fifteen.

Aim Of The Study: Clinical and laboratorial characterization of the pediatric population with GE by Salmonella admitted in a level two hospital.

Modified Pseudomonas agar: new differential medium for the detection/enumeration of Pseudomonas aeruginosa in mineral water.

Pseudomonas aeruginosa has been implicated as a foodborne and waterborne pathogen and is now considered a primary infectious agent. In the present study, the survival of P. aeruginosa inoculated in mineral water was evaluated by drop counts on Pseudomonas Agar Base (PAB), PAB with CN supplement X107, PAB with cetrimide, PAB with nalidixic acid, and these media with added FeSO(4).
