| proteus syndrome with huge tonsillar mass causing dysphagia: a rare case. | proteus syndrome is a rare and highly variable hamartomatous syndrome that can affect multiple organ systems. it is characterized by hyperplasia of connective tissue, vascular malformations, epidermal naevi and hyperostosis. most of the cases present to plastic and orthopaedic surgeons. otolaryngologic presentations are minimal. we report such a rare case, which presented with a huge unilateral tonsillar mass causing dysphagia. | 2006 | 16556346 |
| conditions affecting the viability of spheroplasts in urine. | penicillin-induced spheroplasts from escherichia coli and proteus vulgaris, which at neutral ph had little resistance to osmotic lysis, retained viability in media of low osmolality at ph 5.0 to 5.5. in the presence of 1,000 iu of penicillin per ml (ph 5.0) in liquid media, e. coli remained in rod form without conspicuous growth. on hypotonic agar media at ph 5.2 with 1,000 iu of penicillin per ml, the bacteria grew out as l-type colonies. these findings are discussed in relation to penicillin t ... | 1970 | 16557732 |
| prevention of experimental hematogenous and retrograde pyelonephritis by antibodies against enterobacterial common antigen. | rabbits were immunized with common antigen (ca) derived from salmonella typhimurium. animals with ca hemagglutinin titers of 1-320 to 1-81,920 were injected with 10(7) viable proteus mirabilis via the retrograde and hematogenous routes. nonimmune control groups were challenged similarly. from the retrogradely challenged groups sacrificed at 4 weeks, pyelonephritis was found in 89% of the control animals but not in those immunized. bacteriuria was present in 89% of the controls but in only 61% of ... | 1970 | 16557817 |
| effect of mg and ethylenediaminetetraacetate on the in vitro activity of coumermycin a(1) and novobiocin against gram-negative bacteria. | the effect of mg(2+) and ethylenediaminetetraacetic acid (edta) on the in vitro activity of coumermycin a(1) and novobiocin was determined against pseudomonas aeruginosa, escherichia coli, klebsiella pneumoniae, and proteus mirabilis grown in trypticase soy broth or defined synthetic medium. in the presence of edta, the activity of coumermycin a(1) was significantly enhanced (8- to 40-fold) against all four organisms in the synthetic medium lacking mg(2+); novobiocin activity was increased to a ... | 1970 | 16557848 |
| agar-gel precipitating antibody in pseudomonas aeruginosa infections. | the human immune response to pseudomonas aeruginosa infection was studied by using the double diffusion in agar-gel technique. antigens from fisher-devlin-gnabasik immunotypes were prepared by both trichloroacetic acid extraction and ultrasonic disruption. serum from 72 of 168 patients (43%) from whom p. aeruginosa was isolated formed from one to eight precipitin bands. precipitins were demonstrated in the sera of 60 of 66 (91%) patients recovering from bacteremia and deep infections; however, t ... | 1970 | 16557868 |
| factors affecting the transmission of salmonella by flies: natural resistance to colonization and bacterial interference. | groups of immobilized gnotobiotic houseflies, musca domestica l., were mono-contaminated with graded doses of salmonella typhimurium, bicontaminated with s. typhimurium and proteus mirabilis, and multicontaminated with s. typhimurium and a mouse fecal flora. of 45 flies fed an average of 22 salmonella cells alone, 26 showed bacterial multiplication, up to 1.4 x 10(7) in one case. there was a fairly consistent increase in percentage of salmonella excreters with increasing input, so that all flies ... | 1970 | 16557919 |
| cephalexin: absorption and excretion as related to renal function and hemodialysis. | cephalexin is a new semisynthetic cephalosporin c derivative, which is well absorbed from the gastrointestinal tract and excreted in high concentration in the urine. even in patients with impaired renal function, the concentrations of cephalexin present in the urine are adequate for the treatment of most urinary tract infections produced by escherichia coli, klebsiella, and proteus mirabilis. in anephric patients, single doses of 250 or 500 mg of cephalexin resulted in high, prolonged serum conc ... | 1971 | 16558013 |

| permanent alterations of the l-forms of proteus and salmonella under various conditions. | l-forms obtained from three strains of proteus and from one strain of salmonella have been kept for 15 to 20 years by weekly or monthly transfers on agar plates containing penicillin. the morphology and growth requirements of these strains have changed. they now grow abundantly on the surface of agar and in broth. the cultures consist of large bodies, small granules, and transitional forms. these organisms are more resistant to distortion and stain more deeply than organisms of the usual l-forms ... | 1970 | 16559115 |
| alterations of the l-forms of a sporebearing bacillus. | a large pleomorphic gram-negative bacillus developed as a contaminant on blood-agar. spores were formed in one culture. l-forms were produced with penicillin on blood-agar with 2.5% nacl; they grew well when transplanted to agar with 0.5% nacl. after several transplants and long incubation of the l-forms without penicillin, in three transplants small gram-negative pleomorphic bacilli grew, but no l-forms. this occurred once on blood-agar and twice on 30% gelatin. the growth obtained from these s ... | 1970 | 16559116 |
