[Modifications of the fluorescence method for detecting salmonella in feces]

The Authors illustrate two modifications of the indirect method for identifying Salmonellae on faeces using fluorescent antibodies. They compare a Commercial polyvalent serum with serum containing only the fundamental antigens of groups B, C and D of Kauffmann-White with the aim of reducing the phenomenon of aspecificity. In order to reduce the time required for this test they substitute the enrichment of the specimen in broth by filtering, first the specimen of faeces and then, successively, centrifuging the filtrate. These two modifications have been demonstrated satisfactorily when the test is carried out in children with active gastroenteritis.
