serum and cerebrospinal fluid concentrations of rifampicin at two dose levels in children with tuberculous meningitis.twenty patients of tuberculous meningitis (tbm) in age group of 6 months to 10 years included in the study were divided into two groups of 10 patients each. rifampicin was administered in dosage of 10 mg and 7.5 mg/kg bw to each patient of groups i and ii respectively. drug concentrations in serum and csf of these patients were measured by a microbiological tube dilution method using a strain of sarcina lutea. in group i mean serum and csf concentration was 3.84 micrograms/ml and 0.178 microgram ...19979465533
antimicrobial effects of aqueous plant extracts on the fungi microsporum canis and trichophyton rubrum and on three bacterial species.aqueous extracts of 10 plants were tested for their ability to inhibit trichophyton rubrum and microsporum canis, the aetiological agents of dermal fungal infections in humans. these extracts were also evaluated for their activity against some bacteria. aqueous extracts from the leaves of inula viscosa produced detectable antifungal activity against these dermatophytes.19989489036
the mitochondrial phosphoglyceroyl-atp-containing polymer, purinogen, is unchanged by cardiac ischaemia and reperfusion but may function in the regulation of free intracellular inorganic phosphate concentrations.previous work in our laboratory demonstrating large unexplained systematic variations in the heart contents of free adenine nucleotides led us to propose the existence of some unrecognised sequestered form and thence to the purification of very labile acid-insoluble oligomers which we characterised as oligo[3-phospho-glyceroyl-gamma-triphospho(5')adenosine(3')] , abbreviated to (pg-atp)n. more recently, we provided evidence that these oligomers appear to be the end chains of a complex polymer lo ...19989652397
attachment of the chromosome to the cell poles: the strategy for the growth of bacteria in two and three dimensions.bacteria such as staphylococcus, lampropedia, and sarcina develop in characteristic two-or three-dimensional groups of cells. we propose here a model of how bacteria may generate such groupings by an extension of an earlier model for rod-shaped bacteria. no other mechanism for forming two- or three-dimensional structures of groups of cells has been proposed. our earlier model for division of rod-shaped bacteria into nearly equal-sized daughters assumed that the origin and terminus dna were attac ...199910395815
antimicrobial activity and stability of tingenone derivatives.quinone-methide triterpenes of the tingenone series were evaluated for their antimicrobial activity. these compounds were effective against bacillus cereus, b. subtilis, sarcina lutea, staphylococcus aureus, microsporum gypseum and a gram-negative bacterium, klebsiella pneumoniae. under acidic conditions, the quinone-methide part of these compounds rearranged into the divinyl-phenolic system, and the antimicrobial activity was thus lost.199910418334
bacteriological studies of blood, tissue fluid, lymph and lymph nodes in patients with acute dermatolymphangioadenitis (dla) in course of 'filarial' lymphedema.filarial lymphedema is complicated by frequent episodes of dermatolymphangioadenitis (dla). severe systemic symptoms during attacks of dla resemble those of septicemia. the question we asked was whether bacterial isolates can be found in the peripheral blood of patients during the episodes of dla. out of 100 patients referred to us with 'filarial' lymphedema 14 displayed acute and five subacute symptoms of dla. all were on admission blood microfilariae negative but had a positive test in the pas ...199910546838
absorption kinetics and bioavailability of cephalexin in the dog after oral and intramuscular administration.the pharmacokinetics of cephalexin, a first generation cephalosporin, were investigated in dogs using two formulations marketed for humans, but also often employed by practitioners for pet therapy. cephalexin was administered to five dogs intravenously and intramuscularly as a sodium salt and by the oral route as a monohydrate. the dosage was always 20 mg/kg of active ingredient. a microbiological assay with sarcina lutea as the test organism was adopted to measure cephalexin concentrations in s ...199910597534
sarcina -like bacteria, clostridium fallax and clostridium sordellii in lambs with abomasal bloat, haemorrhage and ulcers.a study of abomasal disease in lambs aged 2-5 weeks, made during the period 1993-1998, included 67 cases and 45 non-affected controls. gross pathological findings included various combinations of bloat, haemorrhage and ulcers in the abomasum. sarcina -like bacteria were found in sections and smears from the abomasum of 79% (53/67) of the cases. from one case, a lamb with abomasal bloat, the anaerobic "packet"-forming sarcina ventriculi was cultivated from the abomasal contents and identified by ...200010684688
metabolites of colletotrichum gloeosporioides, an endophytic fungus in artemisia mongolica.a new antimicrobial metabolite, named colletotric acid (1), was isolated from a liquid culture of colletotrichum gloeosporioides, an endophytic fungus colonized inside the stem of artemisia mongolica. the structure was determined using spectroscopic methods (eims and fabms,(1)h and (13)c nmr, (1)h-(1)h cosy, hmbc, and hmqc). compound 1 inhibited the growth of bacillus subtilis, staphylococcusaureus, and sarcina lutea with minimal inhibitory concentrations (mics) of 25, 50, and 50 microg/ml, resp ...200011087599

studies on aminopyrazoles: antibacterial activity of some novel pyrazol.hydrazones 2a-d were prepared from diazotiazation of sulfanilamide or its derivatives followed by coupling with ethyl cyanoacetate. 3-aminopyrazoles 3a-d were obtained by refluxing of 2a-d with hydrazine hydrate in ethanol. [bis(-methylthio)methylene]malononitrile (4) was reacted with aminopyrazoles 3a-d in refluxing dmf containing triethylamine to yield the novel pyrazolo[1,5-a]pyrimidines 6a-d. the anilino derivatives 8a-h were obtained by fusion of compounds 6a-d with aromatic amines. when co ...200011152240
lactic acid bacteria from healthy oral cavity of thai volunteers: inhibition of oral pathogens.the aims of the present study were to screen and characterize the antimicrobial lactic acid bacteria which were isolated from healthy oral cavities of thai volunteers, and to characterize their inhibiting substances. among 3790 isolates (suspected to be lactic acid bacteria) from 130 volunteers, five showed an appreciable effect against sarcina lutea atcc 9341, bacillus cereus atcc 11778, escherichia coli atcc 25922, staphylococcus aureus atcc 6538, streptococcus mutans dtmu 1, strep. salivarius ...200111168719
methylosarcina fibrata gen. nov., sp. nov. and methylosarcina quisquiliarum sp.nov., novel type 1 methanotrophs.two novel species of obligate methane-oxidizing bacteria, isolated from landfill soil, were characterized. both strains were unusual in that some members of the population grew in irregularly shaped, refractile cell packets that resembled sarcina-like clusters. electron microscopy revealed that the cell packets were covered with a slime layer and the cells contained many large granular inclusion bodies. the individual cells of each strain were sometimes motile and had differing morphologies. iso ...200111321107
production of the gram-positive sarcina ventriculi pyruvate decarboxylase in escherichia coli.sarcina ventriculi grows in a remarkable range of mesophilic environments from ph 2 to ph 10. during growth in acidic environments, where acetate is toxic, expression of pyruvate decarboxylase (pdc) serves to direct the flow of pyruvate into ethanol during fermentation. pdc is rare in bacteria and absent in animals, although it is widely distributed in the plant kingdom. the pdc gene from s. ventriculi is the first to be cloned and characterized from a gram-positive bacterium. in escherichia col ...200111535783
ultra-high vacuum and microorganisms.experimental study of the space environment effect on living organisms is one of the most important tasks of exobiology. however location of the living organisms under study outside space vehicles and sputniks is combined with technical difficulties. therefore it is much more suitable to reproduce conditions found in space in laboratory and to study its effect on living cells. it was proved that low temperatures, even those approaching absolute zero do not kill microorganisms. the fact of microo ...196512035798
female genital tissue concentrations of roxithromycin.a new macrolide, roxithromycin, appears to have some interesting pharmacokinetic characteristics dissimilar to those of erythromycin, e.g. it has the unusual property of a long serum half-life and the possibility of once daily dosing. moreover tissue levels are higher than those obtained with other macrolides, and the drug is still present in the tissues up to 24 h. after dosing. the pharmacokinetics of roxithromycin were studied in 36 women undergoing gynecological surgery, and divided by means ...199112041780
