Outer membrane protein profiling to distinguish between Haemophilus aegyptius and non-capsulate Haemophilus influenzae biotype III.
Outer membrane protein profiling was used to assist in determining the identity of an isolate of Haemophilus spp. that was presumptively identified as non-capsulate Haemophilus influenzae biotype III. The possibility that this strain was in fact Haemophilus aegyptius was queried because of clinical information and the source of the isolate. Sodium dodecyl-sulphate polyacrylamide gel electrophoresis was used to establish the identity of the isolate as non-capsulate H. influenzae biotype III and no H. aegyptius. Generally, protein profiling compared very favourably with other standard tests for identifying H. aegyptius: the method was easily and rapidly performed and gave an unequivocal result.
