Identification and biotyping of clinical isolates of Acinetobacter.

Author information

Unité INSERM 199, Institut Pasteur, Paris.


A total of 343 Acinetobacter strains, most isolated from hospital patients, were identified using a 16-test system (acid production from glucose, gelatin hydrolysis and utilization of 14 carbon sources) associated with tests for growth at 37, 41 and 44 degrees C. Of 299 nosocomial isolates, 253 were identified as A. baumannii, 20 as Acinetobacter genospecies 3, 8 as A. haemolyticus, 8 as A. lwoffii, 4 as A. johnsonii and 6 as other (presently) unnamed species. A biotyping system based on the utilization of levulinate, citraconate, L-phenylalanine, phenylacetate, 4-hydroxybenzoate and L-tartrate allowed recognition of 17 biotypes among 247 A. baumannii isolates. This biotyping system should be useful in epidemiological studies of Acinetobacter strains.
