In the last years, importance of Enterococcus has been increasing because it is now known as causal agent of difficult-to-treat nosocomial infections, mainly due to their antimicrobial resistance. We identified Enterococcus strains using selective media to isolate it, differential assays for strains identification, and standarized disk-diffussion methods to assess antimicrobial susceptibility. Between march and november 1996, 113 strains of Enterococcus were isolated, 65,4% of which come from vaginal discharges, and the remainder from seminal fluid, urine specimens, faringeal secretions, ascitid fluid, sputum, skin wounds samples, prostatic fluid and uretral fluid. E. faecalis give a total of 88,5% of isolates, followed by E. faeccium, E. pseudoavium, E. avium, E. durans y E. raffinosus. Antibiogram analysis using 13 antimicrobial single drugs and another 2 combined with betalactamase-in...

Otorhinolaryngologic diseases in two Hospitals of Lima, hoth in children and ill adults, were studied looking for Moraxella catarrhalis along 12 months. 318 samples front the same miniher of patients were obtained; 40% of which were negative for pathogenic bacteria. Of the remaining 60%, 31% showed Staphilococcus aurcus as the causative agent, followed by Streptococcuspneumoniae in the 19%,Miraxella catarrhalis lit 16% and Haemophilus influenzae in 10%.The most important symptom was purulent rhinorrhea.Streptococcus pneumoniae, Moraxela catarrhalis and Haemophilus influetizae were isolated, ill most of cases, front boys younger than 14 years old.15% of the S. aureus isolated strains were oxacillin-resistant, 11% of tile S. neumoniae isolated strains were penicillin- resistant, and 70% of the M. catarrhalis as well as 5% of the H. influenzae isolated strains were, lactamase producers.Our ...
