| studies on streptococcal bacteriophages. ii. adsorption studies on group a and group c streptococcal bacteriophages. | evidence has been presented that group c bacteriophages differ as to their inactivating site on the streptococcal cell wall. while all three phages adsorb to isolated cell walls, only the c1 phage was inactivated by enzymatically prepared group-specific carbohydrate. none of the group c phages were inactivated by chemically extracted group-specific carbohydrate. in contrast, all virulent group a streptococcal bacteriophages adsorbed only to living group a streptococci. however, group a temperate ... | 1968 | 4384046 |

| in vitro antimicrobial activity and human pharmacology of cephaloglycin. | serum and urine concentrations of cephaloglycin (an orally absorbed derivative of cephalosporin c) were determined in normal volunteers and in patients. the in vitro activity of cephaloglycin was also studied. all strains of group a streptococci (streptococcus pyogenes) and diplococcus pneumoniae were inhibited by 0.4 mug of cephaloglycin per ml. eighty per cent of the staphylococcus aureus strains and about 50% of the escherichia coli and proteus mirabilis strains were inhibited by 1.6 mug of c ... | 1968 | 4385749 |

| predicted and unpredicted cross-reactions of an acetylphosphogalactan of sporobolomyces yeast. | the teichoic acid of streptococcal group n, with end groups of galactose phosphate, had been shown to cross-react with antipneumococcal sera of types vi, xiv, xvi, and xxvii. end groups of d-galactose-1-phosphate in the phosphogalactans of sporobolomyces yeasts made it predictable that these galactans would precipitate the same antipneumococcal sera and also antisera to streptococcal group n. the predictions were verified, and other unpredicted reactions were found. precipitation of much of the ... | 1968 | 4385642 |

| effect of inoculum size on in vitro susceptibility testing with lincomycin. | there is disagreement in the literature as to whether lincomycin is primarily a bacteriostatic or a bactericidal agent against gram-positive cocci and also regarding the levels of activity of this agent against susceptible microorganisms. these questions were examined in a study of the effect of inoculum size on the results of tube dilution susceptibility determinations with lincomycin against 49 clinical isolates of staphylococcus aureus and 25 strains of streptococci and pneumococci. lincomyci ... | 1968 | 4387221 |
| cephalexin and cephaloglycin activity in vitro and absorption and urinary excretion of single oral doses in normal young adults. | a large number of recently isolated bacterial pathogens were tested for susceptibility to cephalexin and cephaloglycin by the replica inoculating method. strains of group a hemolytic streptococci, viridans (alpha and gamma) streptococci, pneumococci, gonococci, meningococci, and penicillin g-sensitive staphylococcus aureus were all moderately to highly susceptible to both of these cephalosporin analogues, nearly all of the strains being two to eight (median four) times more susceptible to cephal ... | 1968 | 4387222 |
| carbenicillin: activity in vitro and absorption and excretion in normal young men. | carbenicillin is a new semisynthetic penicillin which differs from other penicillins in showing moderate antibacterial activity against pseudomonas. its activity in vitro is enhanced at low ph. serum binding is of low order and does not appreciably alter activity. strains of pseudomonas exposed to subinhibitory concentrations of carbenicillin rapidly develop resistance by a mechanism that does not depend upon destruction of the drug. in normal subjects, high levels of anti-pseudomonas activity a ... | 1968 | 4387223 |

| penicillin-resistant variants of pneumococci. | all of the 74 strains of pneumococci isolated from human infections from 1963 to 1964 proved to be uniformly and highly susceptible to penicillin. of these strains, 15 were identified by capsule-swelling reactions and were submitted to serial transfer in the presence of increasing concentrations of penicillin. highly penicillin-resistant mutants were selected from 14 of the 15 strains, whereas one strain was moderately resistant. of these mutants, 11 could still react with specific antiserum, an ... | 1968 | 4384590 |

| bacteriology and clinical significance of hemolytic haemophilus in the throat. | hemolytic haemophilus are rarely isolated in the clinical laboratory, as they do not grow on sheep or human blood-agar alone. on rabbit blood-agar they grow well and are hemolytic, but they grow less well and are not hemolytic on sheep blood-agar with added x and v factors. a survey was made to determine their incidence in pharyngitis. from 28 of 100 sore throats and from 57 of 100 normal throats, only normal bacterial flora were isolated. beta-streptococci were present in significant numbers in ... | 1968 | 4384589 |

| mutation in pneumococcus type 3 affecting multiple cistrons concerned with the synthesis of capsular polysaccharide. | the genetic behavior in transformation reactions of 20 noncapsulated mutants of pneumococcus type iii suggests that each has a single-site mutation in the locus controlling the synthesis of uridine diphosphate glucose (udpg) dehydrogenase. each strain is capable of yielding transformants of the binary capsular type si-iii when exposed to deoxyribonucleic acid (dna) from type i cells. one additional mutant reacted differently and behaved as if it were a multisite mutant with the mutation affectin ... | 1968 | 4386791 |
| antibodies to pneumococcal polysaccharides: relation between binding and electrophoretic heterogeneity. | antibodies to type iii and type viii pneumococcal polysaccharides were examined with respect to ligand binding and electrophoretic heterogeneity. both antibodies showed apparent binding homogeneity, although multiple light chain and heavy chain electrophoretic species were demonstrated. | 1968 | 4386872 |
| pneumococcal c-substance, a ribitol teichoic acid containing choline phosphate. | 1. pneumococcal c-substance was isolated from the non-capsulated pneumococcus 1-192r, a.t.c.c. 12213, by extraction with trichloroacetic acid solution followed by chromatography on deae-cellulose (hco(3) (-) form). 2. the polymer contains 7.0% of phosphorus and 6.0% of nitrogen and is composed of phosphate, n-acetyl-d-galactosamine, d-glucose, n-acetyldiaminotrideoxyhexose, ribitol and choline in the molecular proportions 2:1:1:1:1:1. 3. after acid hydrolysis, d-galactosamine hydrochloride and g ... | 1968 | 4387389 |

| unstable binary capsulated transformants in pneumococcus. | through transformation reactions, binary capsulated si-iii strains of pneumococci have been isolated that are unstable and lose the si capsular genome at high frequency. the instability is caused by the specific mutation in the siii capsular genome common to all of the unstable strains. in the family of strains studied, the si capsular genome was integrated into the recipient chromosome in at least two loci: one apparently adjacent to the resident capsular genome and a second some distance from ... | 1969 | 4389232 |
