1. In the course of the examination of sputum from cases of lobar pneumonia, observations have been made on the incidence of the chief types of pneumococci. In the district from which the material was obtained, there was an apparent local diminution in the number of cases of lobar pneumonia due to Type II the figures were 326 per cent. of Type II cases in the period 1920–22, and only 74 per cent. in the period 1924–27. The incidence of Type I was approximately the same in the two periods, the… 
The Serological Classification of Streptococcus pyogenes
  • F. Griffith
  • Medicine, Biology
    Epidemiology and Infection
  • 1934
TLDR
The haemolytic streptococci associated with scarlet fever, tonsillitis, septic conditions, etc., belong to one group or species designated Streptococcus pyogenes, and the principles involved in the serological classification of a bacterial group are discussed.
The History of Pneumococcal Disease
This chapter reviews some of the major events in the history of Streptococcus pneumoniae—events that have led to our modern understanding of the pathogenesis, diagnosis, treatment, and prevention of
The Relation of Virulence in Pneumococci to Disease, with a Comparison of Virulence of the Different Types of Pneumococci in various Pathological Conditions

Pneumococci form a group of organisms of which the individual strains exhibit wide differences in character. Like the streptococci, certain types of which they closely resemble, they show a
ON STRAINS OF A MONOPHASIC SALMONELLA VARIANT 1
TLDR
This recent accumulation of a rather remarkable number of members of the monophasic variant group led to a restudy of the epidemiologic, biochemic, and serologic characteristics of the cultures in the hope that some clue to the ancestry of the type might be found.
Current Problems in Studies of Streptococci Second Griffith Memorial Lecture
TLDR
It is now known that certain M-type infections with some strains are followed by epidemic glomerulonephritis, and infections with other strains of the same type occur in streptococcal epidemics unassociated with nephritis.
Growth Curve of S. Pneumoniae

TLDR
This work has extensively studied lysogeny with E.coli K-12 and its virus bacteriophage lambda and found that the virus COVID-19 (RNA genome) in the authors' respiratory cells may be responsible for their antigenic variation.
The discovery of pneumococcal type transformation: an appreciation
  • W. Hayes
  • Biology, Medicine
    Journal of Hygiene
  • 1966
TLDR
A series of careful and painstaking experiments show beyond doubt that the ability to produce a polysaccharide capsule can regularly be restored to ‘rough’ (R) strains of pneumococci which have lost it, by the subcutaneous inoculation of mice with an excess of heat-killed, capsulated (S) virulent bacteria.

Growth Curve of S. PNEUMONIAE -A Serious Pathogen
TLDR
Solution for the global population is to develop now an alternative preventive, lowcost hometherapy by inhibiting the growth of this pathogen by understanding the growth curve of such a pathogen.
Changing the Ecology of Pneumococci with Antibiotics and Vaccines
TLDR
This chapter describes the mechanisms and consequences for the pneumococcal population of the selective pressures imposed by antibiotics and vaccines, and emphasizes the effects of vaccines and antibiotics on the ecology of pneumococci taking place against a background of a genetically diverse population structured by direct and indirect ecological interactions between strains.
