Head lice collection in Senegal.
A: Head lice collection areas (Dakar, Kaolack, Sine-Saloum, Dielmo and Ndiop). B: Head lice collection sites in the suburbs of the Dakar region. Diamonds: number of lice positive for A. baumannii; green diamonds: A. baumannii negative for the blaOXA23-like gene; red diamonds: A. baumannii positive for the blaOXA23-like gene.

CLUSTAL W2 nucleotidic alignment of the three blaOXA23-like-positive A. baumannii found in lice (indicated louse 1 to 3) and of the six blaOXA23-like-positive A. baumannii found in human stool samples (indicated stool 1 to 6).
The blaOXA23-like gene AJ132105 was taken as reference.

PFGE and hybridization analysis.
A. Pulsed field gel electrophoresis (PFGE) profiles obtained for the two Acinetobacter baumannii strains isolated from the stool samples from two patients living in Mbao. The Low Range PFG Marker (LRM) was used as molecular weight marker. B. Southern blot profile obtained for the two Acinetobacter baumannii strains isolated from the stool samples from two patients living in Mbao after hybridization against the blaOXA-23 like DIG-labeled probe. Arrows indicate putative plasmids.
