False-negative test results in the Slidex Staph Plus (bioMérieux) agglutination test are mainly caused by spa-type t001 and t001-related strains

Abstract: The relative sensitivity of commercial agglutination kits for fast identification of S. aureus is usually given to be about 98%. This reported sensitivity has sometimes been questioned. In this study, three collections of molecularly defined, single-copy strains of S. aureus were used to compare the sensitivities of agglutination-based identification and the MALDI-TOF mass spectrometry-based identification using the Biotyper 2.0 database to a molecularly defined reference method. Clinical isolates (n = 363) of… Show more

“…In many species, this identification is superior to the classical biochemical identification approaches [7,9,19]. A high amount of latex bead agglutination-negative S. aureus isolates have recently been described [35]. The use of such fast agglutination-based tests for the identification of suspected S. aureus isolates should, thus, be reconsidered and a MALDI-TOF MSbased identification should be favored instead.…”
