Nosocomial Pneumonia Associated to PVL-Producing Staphylococcus aureus in Children in Benin
Figure 2
Schematic representations (AI to III) of PFGE SmaI fingerprints from the three major clones of S. aureus isolates obtained from the pneumonia outbreak (from 3 to 11 isolates per patient) are comparable with isolates obtained from some controlled foods (A1 to 6). Isolates issued from patient 1 and one of the controlled foods (lanes AI, A1, and 2), isolates issued from patients 2, 4, and 6, respectively (all comparable for patients 2 to 7, 9, and 10 and specific nurturing) (lanes AII, A3, 4, and 6); from isolates issued from patient 8 (lane AIII); and from the isolates issued from the community case of pneumonia observed in an adult at the same hospital during the study period. During the same period of the outbreak, other PVL-producing isolates were obtained from other foods, environment of the hospital service, and personnel (b); they distributed within 16 pulsotypes, which for some of them were retrieved from different points of environment and nurses. Other series of positive isolates mainly concerned foods.
