Priority of Micrococcus mucilaginosus Migula 1900 over Staphylococcus salivarius Andrewes and Gordon 1907 with proposal of a neotype strain

Abstract

Gordon in 1967 isolated a species t o which h e applied the n a m e Staphylococcus salivarius Andrewes and Gordon 1907. This is considered in Index Bergeyana (1966) to constitute a legitimate name. T h e r e is no r e a s o n t o doubt that Gordon's strains a r e , indeed, t r u e r e -i s o l a t e s of S. salivarius. However, extensive biochemical studies and-DNA base composition analysis in a m a t e r i a l of analogous isolates necessit a t e t r a n s f e r ot this entity t o the genus Micrococcus (Bergan

NOTES: Stomatococcus mucilaginosus gen.nov., sp.nov., ep. rev., a Member of the Family Micrococcaceae

“…Habitat: frequently isolated from the human mouth and upper respiratory tract. Also found in bronchial secretions and blood cultures (3,4,6,12).…”

“…The G+C content of the DNA is 56 to 60.4 mol% (as determined by the thermal denaturation and buoyant density methods) (4,6,8,12).…”

Mechanistic Model of Rothia mucilaginosa Adaptation toward Persistence in the CF Lung, Based on a Genome Reconstructed from Metagenomic Data

“…R. mucilaginosa was first isolated from milk in 1900 as Micrococcus mucilaginosus [15]. It was later re-isolated and further studied by Bergan et al in 1970 [16], and renamed Stomatococcus mucilaginosus in 1982 based on its 16S rDNA and biochemical characteristics [17]. A recent study comparing S. mucilaginosus to Rothia dentocariosa and another unknown species (later known as Rothia nasimurium ) led to the reclassification of S. mucilaginosus as R. mucilaginosa [18].…”

“…It has variable catalase activity, reduces nitrate, and hydrolyses aesculin [17]–[19]. It is a facultative anaerobe commonly found in the human oral cavity and upper respiratory tract [16], [20], [21], and occasionally the gastrointestinal tract [22], small intestinal epithelial lining [23], tongue [24], [25], teeth [26], [27], colostrum [28], breast milk [29], and dental plaques [30], [31]. Although R. mucilaginosa is commonly regarded as normal flora of the oral cavity and upper respiratory tract, its association with a wide range of diseases (Table S1) highlights its potential as an opportunistic pathogen, especially in immuno-compromised patients [32].…”

REISOLATION OF MICROCOCCUS MUCILAGINOSUS MIGULA 1900

“…Consequently, the Group A strains belong to the genus Micrococcus. Due to this fact, the classification given to them by Gordon ( 19), Staphylococcus saliuarius ( 1 ), would have to be changed ( 8 ) . However, it appears that an earlier name is available for this species, M .…”
