phospholipase d activity of gram-negative bacteria.a phospholipase hydrolyzing cardiolipin to phosphatidic acid and phosphatidyl glycerol was characterized in gram-negative bacteria but was absent in preparations of gram-positive bacteria, saccharomyces cerevisiae, and rat liver mitochondria. in cell-free extracts of escherichia coli, salmonella typhimurium, proteus vulgaris, and pseudomonase aeruginosa, this cardiolipin-hydrolyzing enzyme had similar ph and mg2+ requirements and displayed a specificity which excluded phosphatidyl glycerol and p ...1975360
disorders of micturition in bacterial prostatitis.measurements of urinary flow rate were performed in 16 patients with established prostatitis before and after a course of antimicrobial therapy. before treatment the maximum flow rates were poor with abnormal flow curves and significant improvement in voiding characteristics were observed with treatment (p less than 0.01). a preliminary electrophysiological (emg) study of sphincter activity suggested that the obstruction to the flow of urine was at least in part due to failure of the external sp ...1975681
profiles for ph, temperature, and dissolved o2 levels in enzyme production: monitoring in small-scale fermentors.the profiles thus established may be utilized for investigations of an organism's relationship to its microenvironment including metabolic shifts and pathways. areas of maximum respiratory activity, enzyme production, enzyme degradation, and attainment of the stationary phase are quite evident; however, duration and magnitude of the various phenomena may change with nutrient, temperature, and aeration efficiency. practical application of this simplified method would include: a) determination of ...19751123
isolation and characterization of crystalline methylglyoxal synthetase from proteus vulgaris.methylglyoxal synthetase, which catalyzes the conversion of dihydroxyacetone phosphate to methylglyoxal and inorganic phosphate, has been isolated and crystalized in good yields from proteus vulgaris. the enzyme was shown to be homogeneous by a variety of criteria and was found to be a dimer (mr = 135,000; s20,w = 7.2 s) composed of two apparently identical catalytic and physical properties and their interconvertible nature suggest that they do not represent true isozymes. the enzyme is specific ...19761386
microbiological study of gentamiycin.gentamycin prepared at the all-union research institute of antibiotics did not differ by its antibacterial spectrum and the activity level from gentamycin samples from other countries. by its activity against clinical strains of ps. aeruginosa gentamycin was somewhat inferior than polymyxin but much more superior than carbenicillin. an agar-diffusion method using bac. pumilus ntcc 8241 as the test microbe was developed for determination of gentamycin activity. the gentamycin sulfate complex and ...19752095

[bacterial fora of patients treated with bleomycin].microflora of the pharynx, nose, sputum and excrements was investigated. it was found that bleomycin therapy may induce or aggravate the shifts in microbiocenosis of the pharynx and sputum in the direction of pathogenization (increase in the number of staph. aureus, hemolytic streptococci, enterobacteria). a tendency to elimination of bifidobacteria and appearance of proteus in the excrements was observed. complications associated with the treatment are rarely of infectious origin.197658578
antigenic relationship between morganella morganii and yersinia enterocolitica.two new o antigens have been described for the morganella morganii antigenic schema. o antigens of the strains representing the new serotypes (o43 :h2 and o44 : h19, 37) are related to yersinia enterocolitica o9 and o17, respectively.197659520
immunochemical study of the peptidoglycan of gram-negative bacteria.the specificity of antibodies directed against the peptidoglycan of gram-negative bacteria was studied. the peptidoglycans of proteus vulgaris, escherichia coli, moraxella glucidolytica, neisseria perflava, give identical precipitin reactions. by means of inhibition studies with various peptidoglycan subunits and synthetic peptides, it was shown that the antibodies are essentially directed against the peptide moiety of the peptidoglycan: l-ala-d-glu (l)-mesoa2pm-(l)-d-ala, that the peptide react ...197660233
rational choice of penicillins and cephalosporins based on parallel in-vitro and in-vivo tests.because of the unavailability of strictly comparable data, seven representative penicillins and the five cephalosporins currently used in britain were evaluated in parallel, both in vitro and in vivo. penicillin sensitive and resistant strains of staphylococcus aureus and proteus mirabilis were the main test organisms. minimum bacteriocidal concentrations of cloxacillin, flucloxacillin, cephalothin, and cephazolin in serum were much higher than conventional minimum inhibitory concentrations in t ...197661353
"5-amino-5"-deoxybutirosin, a semisynthetic analogue of butirosin a: antibacterial activity in vitro and in mice.aminodeoxybutirosin (ad-btn), the 5''-amino-5''-deoxy derivative of butirosin (btn), was synthesized to improve on the antibacterial activity of btn by preventing bacterial enzymatic phosphorylation at the 5'' position. ad-btn possesses the spectrum characteristic of btn and gentamicin (gtm) and was active at low levels in vitro against a wide variety of gram-negative species including pseudomonas aeruginosa, indole-positive proteus and serratia marcescens; its action was bactericidal against bo ...197662554
the contractile basis of amoeboid movement iii. structure and dynamics of motile extracts and membrane fragments from dictyostelium discoideum and amoeba proteus.motile extracts from d, discoideum and a. proteus have been characterized in order to compare the structural dynamics and chemical regulation of movement in 2 different types of amoeboid cells. the structural dynamics of both extracts involve the formation of a nonmotile cytoskeleton followed by the contraction of actin and myosin to generate both direct contractile force and cytoplasmic streaming. the contractions are regulated by calcium ions and a threshold of ca. 1.0 x 10(-6) m calcium induc ...197722087
[the effect of ear surgery to the immunologic defense system of the middle ear during chronic otitis media (author's transl)].alpha-1-antitrypsin and alpha-2-macroglobuline are very important proteinase inhibitors for the healing process in chronic otitis media, because they can inhibit numerous bacterial and leukocytic proteinases: alpha-2-macroglobuline can block the malignant proteinases of pseudomonas aeruginosa, staphylococcus aureus and proteus vulgaris. in 58 cases in the middle ear secretion was examined and the level of alpha-1-antitrypsin and alpha-2-macroglobulin investigated pre- and postoperatively. by the ...197663098

the bacteriology of skin cysts.thirty-nine clinically uninflamed cysts of the three most common varieties, epidermoid cysts, trichilemmal cysts and steatocystoma multiplex were removed under sterile conditions and the contents cultured under aerobic and anaerobic conditions. seventy-three percent of epidermoid cysts grew significant numbers of organisms whereas none of the trichilemmal cysts did so. the organisms found were the common skin commensals, staphylococcus epidermidis biotype i, anaerobic gram positive cocci of the ...197717428
a polyvalent human gamma-globulin immune to pseudomonas aeruginosa: passive protection of mice against lethal infection.as a means to development of guidelines for therapeutic application to human disease, preparations of human polyvalent gamma-globulin immune to pseudomonas aeruginosa (pg) were studied in acute infections in mice. pg was highly effective in controlling lethal infections induced in mice by the major immunotypes of p. aeruginosa; greater than or equal to 10 microgram of of gamma-globulin per mouse protected against challenge with less than or equal to 10(6) 50% lethal doses of p. aeruginosa. pg wa ...197770492
inhibition of phagocytosis in vitro by obligate anaerobes.a variety of species of obligate anaerobes have been shown to interfere with the phagocytosis and killing of proteus mirabilis and other aerobic bacteria in vitro. although all the obligate anaerobes examined showed this activity, the effect was greatest with strains of bacteroides melaninogenicus and b. fragilis. in contrast, none of the 36 aerobes tested acted in this way. these observations suggest that the presence of obligate anaerobes may be fundamental to the pathogenesis of some types of ...197773952
specific and cross-reactive activation of rabbit peripheral blood lymphocytes by streptococcal vaccines.the ability of primed rabbit blood lymphocytes to respond in vitro to the homologous streptococcal group antigen depends on its presence in culture in the form of vaccine or cell walls thereof. these lymphocytes can also be stimulated in vitro by streptococcal vaccines with chemically related group antigens. the basis for this cross-stimulation apparently resides in shared rhamnose moieties. activation of these lymphocytes was not achieved by vaccines from unrelated bacteria. there is also the s ...197874347

inhibition of bacterial agmatinase by substrate analogs.activity of agmatinase (ec 3.5.3.11) from proteus vulgaris was studied in presence of guanidine derivatives of agmatine as substrates. the guanidine derivatives, containing carboxyl group, did not interact with the enzyme. an inhibitory effect developed if the carboxyl group was esterified. for exhibition of the effect the length of hydrocarbon radical in ligand and presence of hydrophobic groups were important. one of the most effective inhibitor was n-isoamylene agmatine (k1=0.001 m). compound ...197617224
intestinal autoflora of the test subjects in a 6-month biological engineering experiment.during a 6-month bioengineering experiment the intestinal microflora of four test subjects was examined. changes in the composition of different groups of intestinal microflora (bifidobacteria, lactic-acid bacteria, sporogenous anaerobes, proteus, etc) were found. in spite of the unstable pattern of the intestinal microflora and its tendency for simplification, the total number of microorganisms in 1 g of feces remained relatively unchanged in all the test subjects.197715161

resistance to antibiotics of bacteria involved in respiratory infections (author's transl).the present status of resistance to antibiotics of bacteria involved in respiratory infections is reviewed. schematically it can outlined as follows. streptococcus b-haemolyticus as well as pneumococcus did not change their sensitivity to penicillin, but some strains are now resistant to tetracycline. streptococcus viridans, enterococcus and h. influenzae did not change substantially their sensitivity to antibiotics. staphylococcus aureus is the bacterial species that always poses some problems ...197613744
stomach as source of bacteria colonising respiratory tract during artificial ventilation.10 adults had intermittent positive-pressure ventilation for 3--34 days. all 10 had paralytic ileus. microbial overgrowth in the stomach was found in 9 patients (bacterial in 7 and fungal in 2); gram-negative bacteria predominated. the trachea invariably became colonised by bacteria, mainly gram-negative organisms. in 3 instances the gram-negative bacteria were found in the stomach before they appeared in the tracheal aspirate, and in 1 case the pathogen originated in the faeces.197881991
effect of organic mercurials and sulfhydryl compounds on the urease activity of proteus: inhibition by urine and ascorbic acid.meralluride, mercaptomerin, ethacrynic acid, and penicillamine inhibited urease activity of proteus mirabilis. the activity of the organic mercurials and ethacrynic acid was markedly inhibited by human and dog urine. antiurease activity could not be detected in the urine of a human and a dog given meralluride by injection. urine from patients receiving penicillamine also failed to inhibit urease activity. ascorbic acid inhibited, whereas dehydroascorbic acid enhanced, the activity of the mercuri ...197610828
urinary beta 2 microglobulin in upper and lower urinary-tract infections.beta 2-- microglobulin excretion in 24 h urine collections and beta2- microglobulin clearance were significantly increased in patients with upper-urinary-tract infections, but beta 2- microglobulin clearance and excretion were normal in patients with cystitis. beta 2-microglobulin estimation may be used to distinguish between upper and lower urinary-tract infections, except when pre-existing tubular damage is present. voided urine must have a ph above 6 . 0, since beta 2- microglobulin is rapidl ...197986044
