influence of pili on the virulence of proteus mirabilis in experimental hematogenous pyelonephritis.the ability of heavily and lightly piliated proteus mirabilis to infect the renal parenchyma was compared in a model of hematogenous pyelonephritis. cortical abscesses occurred in 13 of 24 rats injected with lightly piliated p. mirabilis but in none of 24 rats challenged with heavily piliated organisms (p less than 0.001). lightly and heavily piliated organisms were cleared from the vasculature equally rapidly and were also delivered to the kidney in equal numbers. during the first 24 hr, howeve ...1978361900

the significance of serum-sensitive bacilli in gram-negative bacteremia.clinical findings from 76 patients (median age 67 years) with gram-negative bacteremia were analysed and related to the sensitivity of the blood isolates to the bactericidal activity of normal human serum. 28 strains (37%) were resistant, an equal number intermediately sensitive and 20 markedly sensitive (26%). no correlation was found between serum sensitivity and origin of the bacteremia, presence of fever or blood granulocyte count. the frequency of shock in immunocompromised patients with se ...1978362514
fermentation, isolation, and biological activity of maduramycin: a new antibiotic from actinomadura a continuing search for new antibiotics, the species actinomadura rubra (sveshnikova et al.) j. meyer et m. sveshnikova 1974 (strain imet 13001) was found to produce a red pigment with indicator properties, designated maduramycin. the pigment (c28h22o10; m.w. 518 m/e-; m.p. 305--310 degrees c (dec.); uvmax 225.307 nm) possesses a strong antimicrobial activity against gram-positive bacteria, including strains which produce inactivating enzymes for some commercial antibiotics. maduramycin forms ...1978362738

bacteriuria in urinary schistosomiasis in egypt a prevalence epidemiologic survey to assess the prevalence of bacteriuria in urinary schistosomiasis was carried out in a region endemic for urinary schistosomiasis in egypt. twenty of 390 (5.1%) school boys aged 5--16 years were bacteriuric. this prevalence rate is more than 10 times greater than that found in comparable surveys in areas non-endemic for urinary schistosomiasis. in this endemic population bacteriuria was found in 6.5% of active egg excreters and 2.3% of non-egg excreters.1978362956
an overview of results of world-wide clinical trials with cefadroxil.céfadroxil, a new semisynthetic oral cephalosporin, is absorbed similarly by fasted and non-fasted subjects, produces sustained serum levels and is eliminated at a relatively slow rate. these pharmacokinetic properties permit less frequent and more convenient dosage scheduling than cephalexin and cephradine and consequently greater patient compliance. cefadroxil was evaluated for safety in 1051 patients and for efficacy in 1030 patients. overall it achieved a 91.8% rate of clinical success resul ...1978363481
a hydroxamic acid from aspergillus nidulans with antibiotic activity against proteus iron-complexing antibiotic with a narrow spectrum of biological activity was produced by several strains of aspergillus nidulans when grown in a low-iron, chemically defined medium. its chemical and biological properties closely resembled those of desferritriacetylfusigen, a metabolite of several other aspergilli and penicillia.1978363670

[elimination of multiple drug resistance of intestinal bacteria in white mice in vivo with proflavine and rimactan].albino mice, infected with 0.4 cu. cm of 10(10) microbial cells (s. heidelberg), were treated with proflavin (0.4 cu. cm of a 0.3% solution) and rimactan rifamycin sv (0.4 cu. cm of a 0.4% solution). proflavin was given singly and four times, daily, in the course of four days, and rimactan was applied four times. given in a single dose proflavin was found to prolong twice as long the life span of albino mice infected with s. heidelberg. when injected four times it lowered considerably the mortal ...1978364820
