Serotyping of clinical isolates of Acinetobacter baumannii and genospecies 13 capable of growth at 44 degrees C: detection of four new serovars.

Four new serovars (sv 35-38) were detected among clinical isolates of Acinetobacter baumannii and the unnamed genospecies 13 capable of growth at 44 degrees C. Polyclonal rabbit antisera were serovar-specific. None of them cross-reacted with 34 previously recognized servars of A. baumannii and genospecies 13 nor with 26 serovars of genospecies 3.
