| human plasma and the antibacterial effect of peritoneal dialysis solutions. | the influence of human plasma on the antibacterial effect of solutions for peritoneal dialysis was studied. the solutions contained 43 meq per litre of either acetate or lactate as the source of base. enough pooled human plasma was added to half of each solution to give a total concentration of a gramme of protein per litre. the numbers of viable organisms from 15 clinical isolates each of staphylococcus aureus, escherichia coli, and pseudomonas species were counted before and after incubation i ... | 1971 | 5541232 |
| the hygiene and marketing of fresh cream as assessed by the methylene blue test. a report by a working party to the director of the public health laboratory service. | the hygiene and marketing of fresh cream in england and wales was investigated by a working party of the public health laboratory service (phls) between 1 october 1968 and 31 july 1969. thirty-one cream-producing dairies were visited and observations made in the light of the code of practice published by the milk and milk products technical advisory committee of the ministry of agriculture, fisheries and food, and the scottish home and health department. suggestions are made in this report to st ... | 1971 | 4326247 |
| epicillin: in vitro laboratory studies. | a new semisynthetic penicillin, structurally related to ampicillin, has been assigned the generic name epicillin, 6-[d-2-amino-2-(1, 4-cyclohexadienyl) acetamido]-penicillanic acid. the antimicrobial spectrum and level of activity of epicillin in vitro are similar to those of ampicillin. in studies with recent clinical isolates, these two antibiotics, when compared with carbenicillin, showed consistently higher antimicrobial activity against staphylococcus aureus, streptococcus pyogenes, escheri ... | 1971 | 4343402 |
| use of the clumping factor reaction for the identification of encapsulated strains of staphylococcus aureus from human sources. | using the clumping factor test on 815 strains of staphylococcus aureus, 775 positive strains were of compact morphology. of 40 negative strains, 39 were diffuse in serum-soft agar. the test may be used to detect capsulated s. aureus strains. | 1971 | 16558041 |
| experimental infection of the skin in the hamster simulating human impetigo. iii. interaction between staphylococci and group a streptococci. | the interaction between staphylococci and group a beta hemolytic streptococci in mixed lesions was investigated in an experimental impetigo model. a strain of staphylococcus of phage type 71, which has been shown in vitro to produce a bacteriocin for streptococci and other gram-positive organisms, eliminates or reduces group a streptococci in mixed lesions. in contrast, staphylococcal strains of phage types 75 and 81, which do not produce a demonstrable bacteriocin in vitro, exhibit no such effe ... | 1971 | 15776563 |
| biological and immunological properties of encapsulated strains of staphylococcus aureus from human sources. | of 875 strains of staphylococcus aureus isolated from human source clinical specimens, 37 (4.2%) were encapsulated strains. these were all negative for clumping factor and could not be typed with bacteriophages or by serology. twenty-one of these did not produce any hemolysins, 15 produced alpha hemolysin, 1 produced beta hemolysin, and 1 produced both beta and delta hemolysins. after one or two subcultures, 27 of the encapsulated strains converted to the compact variant form, all became positiv ... | 1970 | 16557873 |
| flucloxacillin, a new isoxazolyl penicillin, compared with oxacillin, cloxacillin, and dicloxacillin. | flucloxacillin, a new isoxazole penicillin, is active against penicillinase-producing strains of staphylococcus aureus and is well absorbed in man after oral and intramuscular administration. compared with isoxazole penicillins in current clinical use-namely, oxacillin, cloxacillin, and dicloxacillin-flucloxacillin has proved as active against gram-positive cocci, including penicillin-resistant staphylococci. the extent of binding of flucloxacillin to the protein of human serum was similar to th ... | 1970 | 5481218 |
| isolation and partial characterization of a staphylococcal leukocyte cytotaxin. | a factor which attracts rabbit polymorphonuclear leukocytes both in vitro and in vivo was isolated from the culture filtrate of a strain of staphylococcus aureus. the activity of the chemotactic factor was independent of fresh serum and it was nondialyzable. incubation of the factor with heat-inactivated human serum markedly inhibited its chemotactic property. the factor was heat-labile (80 c, 10 min) in the crude culture filtrate but was heat-stable when partially purified. | 1969 | 5776515 |
| ammonium sulfate coprecipitation antibody determination with purified staphylococcal enterotoxins. | the ammonium sulfate coprecipitation technique of farr was applied in a study of the purified enterotoxins of staphylococcus aureus. ammonium sulfate coprecipitation of iodine-131-labeled enterotoxins a, b, and c, with the use of a 1.6 m concentration of (nh(4))(2)so(4), revealed differences in the antigen-binding capacity of normal and immune rabbit sera for the enterotoxins. the coprecipitation technique provided a quantitative test for detecting antibody to enterotoxin that was more sensitive ... | 1969 | 4979439 |
| modified microbiological assay for rapid estimation of antibiotic concentrations in human sera. | antibiotic concentrations in human sera were estimated in 5 to 6 hr by a modified microbiological assay. by using staphylococcus aureus and streptococcus pyogenes as the assay organisms, the seeded assay plates were preincubated for 2 to 6 hr and then were stored at 4 c until used for assay. paper discs saturated with the specimen were placed on the preincubated assay plates with reference discs saturated with known concentrations of antibiotic. after 5 to 6 hr of incubation, zones of antibacter ... | 1969 | 4896101 |
| 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 |
| serological activity of protein a of staphylococcus aureus: the precipitinogen as an antigen for determining antibodies by the passive hemagglutination test. | tanned sheep erythrocytes have been considered incapable of sensitization with the precipitinogen of protein a of staphylococcus aureus, so that the activity of this antigen in serological reactions has so far been studied by means of the agar diffusion test (adt) only. the precipitinogen of the protein a in this study was found to become attached to the tanned erythrocytes and to sensitize them for the passive hemagglutination test (pht). it was determined that, in contrast to nonspecific react ... | 1968 | 4969604 |
