Abstract

ABSTRACT Salinatis (antigenic formula, 4,12:d:eh:enz 15 ) is a rare Salmonella serotype currently designated a triphasic variant of the diphasic serotype Duisburg ( 1 ,4,12, 27 :d:enz 15 ) (underlining indicates that the O antigen is determined by phage lysogenization). Salinatis could also be related to serotype Sandiego (4,[5],12:eh:enz 15 ), from which it might have been derived by loss of H-d flagellin genes. Nineteen Salmonella strains of serotypes Salinatis, Duisburg, and Sandiego were examined by biotyping, Pvu II and Sma I ribotyping, IS 200 fingerprinting, and pulsed-field gel electrophoretic profiling. Results from these methods, used alone or together, indicate that serotype Salinatis is more likely to be related to serotype Sandiego than to serotype Duisburg. For future lists of serotype names, it is recommended that Salinatis be considered a variant of Sandiego.
