The Study of the Streptococci Pathogenic in Man.

Abstract

and will also be subject to the general regulations applicable to Army Reserve officers so far as such regulations do not conflict with those laid down in this Warrant. The sum of £5 will be allowed towards the provision of uniform. We wish that we could consider that the Royal Warrant, the nature and terms of which are here set forth, is altogether calculated to fulfil its object in view, which is really one of national importance, especially in the case of war, for which eventuality all the arrangements for the expansion of the medical service in this respect require to be thoroughly thought out beforehand. VOLUNTEER CORPS.

Streptococcus salivarius and Other Non-hemolytic Streptococci of the Human Throat

“…When Streptococcus salivarius is segregated, the remaining non-hemolytic streptococci of the human throat fall into a rather ill-defined and heterogeneous group which may be most appropriately designated as the Streptococcus mitis of Andrewes and Horder (1906). Although clearly differentiable from Streptococcus salivarius and several of the other species of viridans streptococci, the Streptococcus mitis group appears to be decidedly heterogeneous on the basis of the methods now available for the study of streptococci.…”

“…Since Andrewes and Horder (1906) described Streptococcus equinus, the lactose-non-fermenting streptococcus which predominates in the intestine of the horse, it has been the custom to designate as Streptococcus equinus the nonhemolytic, lactose-non-fermenting streptococci which are isolated from human sources. Floyd and Wolbach (1914), Broadhurst (1915), Holman (1916, Blake (1917), Arnold (1920), Porch (1941), and many others, have reported as Streptococcus equinus such streptococci from human sources, most frequently from the throat but occasionally from urine and from infections.…”

Comparison of antibiotic susceptibility in viridans group streptococci in low and high antibiotic-prescribing General Practices

“…S. salivarius is a common commensal organism of the human mouth and nasopharynx, which is usually non‐pathogenic for the human host, although there have been several reports of S. salivarius ‐related infection . Phenotypically, this species of streptococci was chosen, as it was the most frequently isolated viridans group streptococcus in the mouth and nasopharynx, as well as being easy to isolate, as they produce large mucoid colonies on agar medium containing 5% sucrose, similar to those produced by Leuconostoc species …”

The Lesions of the Kidney in Ulcerative Endocarditis

“…The question of the substantiation of Streptococcus-viridans as a definite species is, however, open to criticism. The work of Andrewes and Horder [1], and Gordon [3], in my opinion, has substantiated the identity of this streptococcus with the common types of streptococcus found in various regions of the alimentary canalnamely, Streptococcus salivarius, which is a normal inhabitant of the mouth, and Streptococcus facalis, which normally inhabits the intestine.…”
