[the effect of modifications of the "penam" part of penicillin o].		1976	826035
respiratory activity as a determinant of radiation survival response.	respiration is depressed in irradiated bacteria reaching a minimum level in most strains at 1-3 h after exposure when incubated in growth medium. since a delay in response is observed, direct action on respiratory enzymes is unlikely. the dosage response of respiration varies widely in the strains studied with do's from 15 kr for escherichia coli bs-1 to 1200 kr for micrococcus radiodurans. all strains exhibit two-component dosage-response curves. escherichia coli bs-1 uniquely possesses a posit ...	1976	788873
concentrations of erythromycin in serum and tonsil: comparison of the estolate and ethyl succinate suspensions.	concentrations of erythromycin were measured in serum and tonsil from children who had received either the estolate or ethyl succinate suspension before surgery. the in vitro assay measured total erythromycin activity against a group a beta hemolytic streptococcus. levels of erythromycin in serum and tonsil after single and multiple doses of the estolate were significantly higher than those after administration of the ethyl succinate. the therapeutic implications of these findings are unknown.	1976	792404
pharmacokinetic interpretation of erythromycin and tylosin activity in serum after intravenous administration of a single dose to cows.	the distribution and elimination kinetics of erythromycin and tylosin, which are macrolide antibiotics, were studied in healthy cows. a single dose (12-5 mg/kg) of drug was administered as an intravenous bolus, and blood samples were collected at precisely timed intervals. the standard cylinder plate bioassay method using sarcina lutea as test organism was employed to determine antibiotic activity in the serum. the results suggested that these drugs are distributed in at least two kinetically di ...	1976	1030820
penicillin tolerance in neisseria gonorrhoeae: evidence disallowing a penicillinase-mediated mechanism from a refined microbiological assay method.	a microbiological assay method has been developed and applied to neisseria gonorrhoeae, for the purpose of detecting enzymatic deactivation of benzyl penicillin. calibration of the method, using strains of escherichia coli k-12 with previously reported penicillinase (ec 3.5.2.6.) activities, has shown that it is extremely sensitive and may be used in a quantitative manner. at the limit of sensitivity the test is able to detect penicillin breakdown in the order of 3 x 10(-3) mug in 48 h, which is ...	1976	814985
quantitative structure-activity relationships. 2. a mixed approach, based on hansch and free-wilson analysis.	based on the theoretical and numerical equivalence of hansch's linear multiple regression model and the modified free-wilson model a mixed approach is developed. the mixed approach is a combination of both models which makes use of the advantages of each model and widens the applicability of hansch and free-wilson analysis. the free-wilson approach now is applicable also in the case of parabolic dependence of biological activity on a particular physical property, e.g., log p or pi. a rational ex ...	1976	818381
[experimental study of an aerosol preparation containing gentamicin (gentasol)].	composition of a suspension aerosol drug, gentasol for local application was developed. it contained gentamycin and prednisolon. the antimicrobial properties of the drug were studied in vitro. it was found that gentasol had a pronounced antimicrobiol effect and inhibited the growth of many microorganisms including cultures resistant to other antibiotics. the drug was active against ps. aeruginosa and proteus, which is an advantage of it as compared to other antibiotic aerosol drugs. the study sh ...	1976	818945
[drug residues in poultry (author's transl)].	the following microbiological tests: the bacillus subtilis bga (bundes-gesundheitsamt) test and sarcina lutea test as well as the test bacteria bacillus stearothermophilus var. calidolactis and e. coli were used to examine whether drug residues were detectable in broiler chickens during and after treatment with various drugs. with the exception of the occidiostat esb3, residues were not found to be present using the two above tests. on the other hand, residues of a number of drugs were detected ...	1976	821173

synthesis and antitumor activity of 2-deamino- and n2-(gamma-hydroxypropyl)actinomycin d.	2-deamino- and n2-(gamma-hydroxypropyl)actinomycin d were synthesized by modification of the parent actinomycin d molecule at the 2 position of the phenoxazinone moiety. the common intermediate was 2-deamino-2-chloroactinomycin d. catalytic hydrogenation of this material afforded the 2-deamino derivative while treatment with gamma-hydroxypropylamine yielded the n2-(gamma-hydroxypropyl) derivative. these 2-substituted actinomycin d derivatives were less potent in microbiological assays than the p ...	1975	809581
[false-positive results obtained on examining slaughtered animals for the presence of antibiotic residues (author's transl)].	as part of the examination of emergency-slaughtered animals for the presence of antibiotic residues, studies were done to see whether false-positive results would be obtained when the sarcina lutea kidney test and bacillus subtilis bga test were performed. when the s. lutea kidney test was positive in cattle, calves and swine, penicillin was invariably found to be present in those animals, the histories of which showed that they had not been given antibiotics. a syringe and an injected fluid con ...	1975	809859
[transfer of organisms during exchange of heat and moisture in air conditioning installations (author's transl)].	with the exhaust air from ventilation and air conditioning installations escaping into the open, the heat content is also lost which fresh air from outside obtains at considerable expense of energy and technical equipment. the heat content, on the other hand, consists of about equal proportions of sensible heat and latent heat which is associated with the moisture content of the air. in order to regain the heat content of the escaping air so as to be able to use it again - and this is becoming i ...	1975	811009
[residues of antimicrobial substances in the meat and organs of slaughter calves].	using a modified gartside diffusion method (1960) the incidence of the residues of antimicrobial substances was followed in two categories of calves commercially slaughtered at the brno slaughter house. for testing the following three collection strains were used: b. subtilis (atcc 6633), b cereus, var. mycoides (atcc 11778), sarcina lutea (atcc 9341). in light weight calves samples of bile, liver, kidney, diaphragmatic and hind limb muscles, in heavy calves, due to technical reasons, only bile, ...	1975	807014
systematic difference in the methylation of ribosomal ribonucleic acid from gram-positive and gram-negative bacteria.	a survey of gram-positive and gram-negative organisms was performed to compare the distributionof n6-methylated adenine. it was found that (i) all the gram-positive strains tested, staphylococcus aureus, sarcina lutea, bacillus stearothermophilus, bacillus subtilis, and bacillus megaterium, contain neither n6-monomethyl adenine (m6a) nor n6-dimethyladenine (m26a) in 23s ribosomal ribonucleic acid (rrna). in the case of s. aureus and streptococcus pyogenes, strains which are clinically resistant ...	1975	807565
synthesis and antibacterial and antifungal activities of 5-nitro-2-furfurylidene polyhalophenoxyacethydrazides viii.	fifteen 5-nitro-2-furfurylidene phenoxyacethydrazides were synthesized, and the antibacterial and antifungal activities of the compounds prepared were determined against different microorganisms. the o-methoxy derivative was found to be the most active compound.	1975	807705
chemistry of cephalosporin antibiotics. 28. preparation and biological activity of 3-(substituted)vinyl cephalosporins.	3-(substituted)vinylcephem nuclei have been prepared by the reaction of 3-formylcephem derivatives with stabilized phosphoranes. appropriate synthetic steps allowed preparation of a series of 3-ethoxycarbonylvinyl- and 3-carboxyvinylcephem derivatives bearing a variety of 7-acylamino functions. the phenoxyacetyl and thiopheneacetyl derivatives of the 3-cyanovinylcephem nucleus were also prepared. although general gram-positive activity was comparable to cephalothin in many cases, against penicil ...	1975	808607

inhibition of microbial growth by fatty amine catalysts from polyurethane foam test tube plugs.	when polyurethane foam test tube plugs are autoclaved, they release volatile fatty amines that inhibit the growth of some microorganisms. the chemical structures of these amines were determined by the use of a gas chromatograph-mass spectrometer. they are catalysts used to produce the foam. the problem of contaminating growth media with toxic substances released from polymeric materials is discussed.	1975	1096816
investigations on the efficacy of surface disinfection and surface cleaning procedures. 3. evaluation of the results of in-use and laboratory tests.	3 disinfectants and 3 disinfectant cleaning agents were subjected to comparative tests as to their germicidal activity. these were (a) laboratory tests with germ carriers and (b) in-use tests with sarcina-contaminated floor surfaces in a medical institute. the results, details of which are given in the two preceding publications, were assessed under the following angles: validity of the test methods, requisite changes of the test procedures and practical usefulness of the different types of prep ...	1975	1106070
amino sugar and amino acid constituents of the cell walls of the extremely halophilic cocci.	cell wall hydrolysates of nine strains of extremely halophilic cocci all contained gylcine, glucosamine, galactosamine, and gulosaminuronic acid. muramic acid was not present in any of the strains.	1975	1119892
microbial degradation of erythromycins a and b.	growing cultures, as well as broken and lyophilized cells of pseudomonas 56 were found to degrade erythromycin a, and lyophilized cells inactivated erythromycins a and b. the enzyme system involved in this degradation was constitutive and the enzyme level in the cells could be increased about 8-fold when oleandomycin or erythromycin b was added to the growth medium. the ability of whole or broken cells to inactivate erythromycin a was completely lost when these preparations were boiled, and the ...	1975	1150530
[distribution of rifamycin sv in de bovine tissues following intramammary administration of rifamastene (author's transl)].	depending on the physiological activity of the udder, from 4 to 95 per cent of the rifamycin sv administered by intrammary injection are absorbed from the udder and approximately 95 per cent of the absorbed rifamycin sv are excreted through the liver. the rifamycin sv eliminated in the faeces will lose its microbiological activity more or less rapidly, depending on the temperature and oxygen tension. accumulation of rifamycin sv in the meat and organs will not occur on intramammary administratio ...	1975	1154345
inhibitory effects of citrates in the determination of trace amounts of penicillin.	in the microbiological assay for the determination of trace amounts of penicillin, it has been shown that sodium citrate and penicillin act synergistically against sarcina lutea. the inhibitory action of citrate appears to involve a sequestering of divalent cations essential to the growth of the organism as shown by minimal inhibitory concentration and agar diffusion studies. the addition of calcium or magnesium to broth or agar at various concentrations overcomes this inhibition, and 0.02 m mag ...	1975	1164006
n-acetyl-l-phenylalanyl-l-phenylalaninol a metabolite of emericellopsis salmosynnemata.	a new metabolite n-acetyl-l-phenylalanyl-l-phenylalaninol was isolated from culture filtrates of emericellopsis salmosynnemata which produces zervamicins i and ii. the structure was assigned from spectral properties and degradative studies.	1975	1184465
mechanism of the inhibitory effect of pas granules on the absorption of rifampicin: adsorption of rifampicin by an excipient, bentonite.	the bioavailability (plasma concentrations, auc and urinary excretion) of an oral solution of rifampicin was investigated in six healthy volunteers. simultaneous administration of pas granules produced a significant decrease in the absorption of rmp, whereas na-pas tablets had no effect. this indicated that the dosage form of the granules and not pas itself was responsible for the interaction, and that the dissolution of rmp was not involved. the interaction could be reproduced by giving dummy g ...	1975	1233228

[antibacterial activity of a lysozyme-like enzyme from staphylococci].	a lysozyme-like enzyme isolated from the culture broth of staph. aureus 712 presented in its native state a lipoproteid complex. the lytic and antibacterial spectrum of the enzyme was similar to that of the egg albumin enzyme. however, the lipoproteid complex was somewhat superior to the egg albumin complex in its activity against micrococcus lysodeikticus, a number of gramnegative bacteria and staphylococci. out of the organisms studied microccus lysodeikticus, sarcina and bac. subtilis proved ...	1975	813563
comparison of the effects of three fluorocarbons on certain bacteria.	three fluorocarbons were tested to determine their effect on bacterial growth. freon 11 and 21 in various concentrations had an inhibitory effect on selected test organisms, but freon 22 had no effect. both aerobic and anaerobic microorganisms, as well as gram-positive and gram-negative species, were included among the bacteria tested. freon 11 and 21 caused a similar response with freon 11 being more inhibitory to some species and freon 21 more inhibitory to others. inhibition was dependent on ...	1975	803403
singlet excited oxygen as a mediator of the antibacterial action of leukocytes.	human polymorphonuclear leukocytes kill a colorless mutant strain of sarcina lutea much more readily than a carotenoid-containing strain. a similar protective effect has been reported in the organism during photodynamic inactivation, where it is attributable to the quenchintg of singlet excited oxygen by carotenoids. the findings with leukocytes support the suggestion that singlet excited oxygen acts as one of the mediators of their bactericidal action.	1974	4415781
