Streptococcus faecalis

Several tetrahydroquinazoline analogs of folic acid were synthesized by Baker and co-workers as potential anticancer agents, and the substance (61), at 50 m/ g/ml, gave a 50% inhibition of growth of Streptococcus faecalis on a Flynn folic acid medium containing 3 m/i,g of folic acid. 

A number of deaza analogs of pteroic acid (182, Ri = R2 = OH) have been prepared and examined by Rydon el al. as antagonists of folic acid in Streptococcus faecalis and Lactobacillus casei. Two of the pyrido[3,2-d]pyrimidines (183, R = OH or OEt, R2 = NH2) showed...

Nearly all microbiologic assays for folic acid activity have used Streptococcus faecalis and Lactobacillus casei. Earlier it appeared that these organisms could not detect folic acid deficiency in man (C2, L8) for example, in one study using S. faecalis there was no detectable activity in the fasting serum of humans (C3). Administration of a loading dose of folic acid with subsequent assay by S. faecalis (G9) has served as a workable means of determining folic acid deficiency (C6), a technique having definite drawbacks (G10). 

Because of the multiplicity of folic acid factors reported in whole blood (Ul), the microbiologic assay for folic acid in whole blood and serum was regarded as valueless (C2, L8, W9) results based on S. faecalis methods (C2, C3) did not contradict this view. Streptococcus faecalis is inferior to L. casei in its utilization of the PGA polyglutamates...

The association between vitamin B6 deficiency and transamination emerged from 1945 when Schlenk and Fisher noted that pyridoxine-deficient rats had a diminished capacity for transamination. In the same year Gunsalus and his colleagues found transamination in Streptococcus faecalis depended on pydridoxal phosphate. The properties of the heat-stable component in purified glutamic-oxaloacetate transaminase were similar to those of pydridoxal phosphate. Later pyri-doxal phosphate was established as an essential coenzyme in many amino acid transformations.

The majority of sepsis cases, especially the more severe forms, have bacterial etiologies. Common bacterial species include Staphylococcus aureus. Streptococcus pneumoniae, Escherichia coli. Salmonella typhi (and other enterobacterial species). Pseudomonas species and haemolytic streptococci in children Haemophilus influenzae and Neisseria meningitidis are important whereas nosocomial episodes of sepsis are frequently caused by Staphylococcus epidermidis. Streptococcus faecalis (syn. enterococci), yeasts and anaerobes.

Studies on growth factors required by certain microorganisms, for example Streptococcus faecalis and Lactobacillus casei, and of their relevance in animal nutrition, led to the isolation and characterization of folic acid, pteroylglutamic acid (104), the structure of which was determined in 1946. It is an essential vitamin for man and together with vitamin B12 it is involved in the development of blood cells. Deficiency causes macrocytic anaemia. Many microorganisms do not use exogenous folic acid, but synthesize their own, and some... 

London and Meyer (33) have demonstrated the presence of a malic enzyme, E.C. 1.1.1.39, in Streptococcus faecalis. In their system, the organism grows at the expense of L-malic acid, producing carbon dioxide, acetate, and ethyl alcohol and NADH as major end products, and a small amount of lactic acid as a minor end product. The authors speculate that the major function of the malic enzyme is to provide energy, presumably...
