Over a 16-month period, Klebsiella pneumoniae isolates from 102 patients admitted to a university hospital in Liege (Belgium) produced extended-spectrum beta-lactamases. Pulsed-field gel electrophoresis of genome macrorestriction patterns with XbaI and antibiotic susceptibility patterns subdivided 39 isolates into eight clonally related groups. Two of them were implicated in the course of this outbreak. They were responsible for successive waves of infection or colonization in different wards of the hospital while the others were encountered sporadically. A beta-lactamase with an isoelectric point of 7.6 and consistent with type SHV-2 characterized all nine isolates chosen among both major groups. [less ▲]

As soon as the early 70's, group B streptococci (GBS) became clearly predominant in neonatal infections. There was a dramatic increase in the incidence of GBS neonatal sepsis and meningitis throughout developed countries and GBS emerged as the leading cause of severe neonatal infections. Most of these infections, associated with high mortality and morbidity, could be prevented by intrapartum chemoprophylaxis given to risk mothers. AAP, ACOG and the CDC issued guidelines for their prevention. Today, in Belgium, there are still no recommendations for the prevention of GBS early-onset infections. [less ▲]

The need of a simple and reliable method for routine yeasts susceptibility testing led us to evaluate two commercially available methods. We investigated the in vitro susceptibility of 67 clinical isolates (26 C. albicans, 32 C. glabrata, 4 C. krusei, 2 C. tropicalis, 2 C. kefyr and 1 S. cerevisiae) to 6 drugs flucytosine (FC), amphotericin B (A), fluconazole (FZ), itraconazole (IT), kétoconazole (K), miconazole (M), comparing two methods Fungitest (Sanofi Pasteur) and Neosensitabs (Rosco). A broth microdilution adaptation from the NCCLS-M27A procedure was used as reference method. Fungitests consist of individually packed 16 wells microplates containing 6 drugs at two critical concentrations in buffered medium. Reading was performed after 24 and 48h incubation. Neosensitabs is an agar diffusion method on Shadomy agar using antifungals tablets. Reading was performed after 24h. For all strains Neosensitabs was in concordance with NCCLS M27-A for FC (94%), A (98%), FZ (55%) I (53%) with p<0.05. Fungitest correlated with NCCLS method for all antifungals after 24 and 48h incubation time (p<0.05) with respectively 95/95% for FC, 100/100% for A, 80/76% for FZ, 81/55% for I and 93/75% for K, and 88/81 for M. Candida glabrata gave the poorest result with Neosensitabs with 28% concordance for FZand 39% for I; therefore the method can't be recommended for this species. Fungitest concordance observed was 55% for I after 48h. Our results suggest that Fungitest is appropriate for routine yeast susceptibility testing. However itraconazole testing has to be improved with this method. [less ▲]

Fifty nosocomial isolates of Serratia marcescens, collected in six Belgian hospitals between 1986 and 1990, were characterized by using pulsed-field gel electrophoresis (PFGE) with XbaI. The results were compared with those previously obtained by three other methods: biotyping, esterase electrophoresis typing and ribotyping with EcoRI and HindIII. Macrorestriction analysis (42 PFGE groups) and esterase typing (42 zymotypes) proved to be the most discriminating, followed by ribotyping (28 ribotypes) and biotyping (10 biochemical profiles). Biotyping would serve as a screen to identify isolates, due to its accessibility. Esterase typing provided a reliable tool to make subdivisions within biotypes because of congruence between biochemical groups and esterase patterns. Additional discrimination was still achieved by ribotyping and PFGE. It is concluded that the combined results of these four markers were useful for distinguishing all epidemic and sporadic isolates.
