| physicochemical and biological properties of sonically treated vi antigen. | electrophoretically purified vi antigen from citrobacter freundii 5396/38 was depolymerized by sonic treatment. the treatment caused an 80% reduction in specific viscosity and a reduction in molecular weight from 1.6 x 10(6) to 3.9 x 10(4). the o-acetyl and n-acetyl contents of the antigen and its infrared spectrum remained unchanged. the sonically treated antigen was only 1% as effective as the original antigen in eliciting protection in mice against challenge with salmonella typhi. sonically t ... | 1967 | 4964477 |

| taxonomic investigations on expressed and cryptic phospho-beta-glucosidases in enterobacteriaceae. | in the enterobacteriaceae, beta-glucosides are catabolized by a complex system formed of three permeases, with partly overlapping substrate specificities, and two hydrolytic enzymes, phospho-beta-glucosidase a and b, which hydrolyze only phosphorylated beta-glucosides. some enterobacteriaceae such as klebsiella-aerobacter (enterobacter) possess the complete system; others possess only parts of it or may have a cryptic phospho-beta-glucosidase activity without permease activity. a screening test ... | 1969 | 4897109 |

| biosynthesis of the o antigen from citrobacter 139. | the biosynthesis of the o antigen of citrobacter 139 (escherichia coli 3 zurich 4,5,12:z(20)) was shown to proceed through a series of lipid-linked intermediates, similar to those involved in o-antigen synthesis in salmonella. galactose was the first sugar incorporated, followed by rhamnose and mannose. abequose was incorporated from cytidine diphosphate (cdp)-abequose only when all three of the other nucleotide sugars (uridine diphosphate galactose, guanosine diphosphate mannose, and thymidine ... | 1968 | 4876133 |
| sisomicin: evaluation in vitro and comparison with gentamicin and tobramycin. | sisomicin is a new antibiotic produced by micromonospora inyoensis. the in vitro activities of sisomicin, gentamicin, and tobramycin, three similar aminoglycosides, were determined against 228 clinical isolates representing 10 genera of common pathogens. no difference was noted in the activities of these antimicrobial agents when assayed by a standard broth dilution technique against klebsiella, enterobacter, escherichia, salmonella, citrobacter, enterococci, or staphylococcus aureus. sisomicin ... | 1973 | 4790572 |

| neonatal meningitis caused by citrobacter koseri. | three cases of neonatal meningitis, two of which were fatal, occurred in a premature baby unit during a period of one week. a fourth case occurred in the same unit six months later. citrobacter koseri was isolated from the cerebrospinal fluid of all four cases. detailed biochemical and serological examination of the organisms showed that two distinct bioserotypes were involved. | 1973 | 4696833 |

| occurrence of potential pathogens in water containing ornamental fishes. | the bacterial population of the water supplied with ornamental fish purchased from retail outlets was examined qualitatively and quantitatively. as many as 10(9) viable aerobic organisms per 100 ml were present, with fecal coliform counts as high as 10(5) per 100 ml. citrobacter, escherichia, pseudomonas, and vibrio were isolated from 75% or more of the samples, whereas aeromonas, alcaligenes, enterobacter, flavobacterium, and streptococcus were isolated from 45 to 65% of the samples. pseudomona ... | 1974 | 4602309 |
| biochemical and antibiotic susceptibility studies of h2s-negative citrobacter. | ninety-four strains of h(2)s-negative citrobacter were biochemically characterized and their antibiograms were determined. the antibiograms demonstrated not only a difference from enterobacter cloacae but also a difference within the citrobacter group between the indole-negative and indole-positive strains. these differences were statistically significant and emphasize the importance of the indole reaction as an aid to speciation of the h(2)s-negative citrobacter. | 1974 | 4602308 |
| a new episomic element controlling fermentative metabolism and excretion of amino acids by citrobacter intermedium c3. | glutamate excretion by colonies of citrobacter intermedium c3 was detected by using the auxotrophic strain leuconostoc mesenteroides p-60. a constant ratio of strain c3 colonies did not excrete glutamate. these colonies were subcultured, and colonial analysis of their descendants established that the change from non-excretor to excretor (sg(-) --> sg(+)) is a spontaneous and random process with occurs at a high rate, and that an equilibrium state results from the back-transition sg(+) --> sg(-) ... | 1974 | 4600693 |

| pressure transducer method for measuring gas production by microorganisms. | a simple method for measuring gas production by microorganisms by using a pressure transducer to sense pressure buildup was developed and tested with members of the coliform group. the test system consisted of a 5.0 lb/in(2) pressure transducer and a pressure equalizer valve attached to the metal cap of a test tube (20 by 150 mm); gas pressure was recorded on a strip-chart recorder. gas pressure response curves consisted of (i) a lag period with no marked increase in pressure, (ii) a rapid press ... | 1974 | 4589123 |
| medium for the isolation of aeromonas hydrophila. | a new differential medium, rimler-shotts, was tested with 109 isolates representing 13 genera of bacteria obtained from aquatic environments and animals. this medium was effective in presumptive identification of the strains of aeromonas hydrophila examined, with 94% accuracy. strains of citrobacter which were hydrogen sulfide-variable could not be separated from a. hydrophila. this medium was designed to facilitate diagnosis of a. hydrophila infections in animals and humans. | 1973 | 4584594 |

| potential pathogens in the environment: isolation, enumeration, and identification of seven genera of intestinal bacteria associated with small green pet turtles. | bacteriological analyses were performed on fecal swabs and the aquarium water of 27 individually purchased specimens of the small green pet turtle, pseudemys scripta elegans. representatives of aeromonas, citrobacter, enterobacter, klebsiella, proteus, salmonella, and serratia were isolated. enterobacter, klebsiella, and salmonella were encountered in 20% or more of the specimens, whereas aeromonas was isolated from 63%. klebsiella pneumoniae counts ranged from 10(3) to 10(4) per milliliter of a ... | 1973 | 4572984 |

| klebsiella biotypes among coliforms isolated from forest environments and farm produce. | samples of water, soil, needles, and bark were collected from three different forest environments and from a pulp and paper mill. in addition, samples of fresh produce were obtained from a local supermarket. all samples were examined for total and fecal coliforms. the counts obtained from the forestrelated samples did not correlate with sample type or location. when 123 isolates were identified biochemically, 71% were klebsiella, 19% enterobacter, 8% citrobacter, and 2% escherichia. all the citr ... | 1972 | 4568255 |
| selective medium for hydrogen sulfide production by salmonellae. | triple sugar iron agar does not reveal hydrogen sulfide production by all salmonella organisms nor does it permit clear-cut separation of those nonsalmonellae which produce h(2)s. numerous media with varied combinations of nutrients, inhibitors, selective agents, ph levels, and metal salts were tested for h(2)s production of cultures of salmonella, citrobacter, edwardsiella, arizona, proteus, providencia, klebsiella, and enterobacter. an agar medium has been devised which promotes growth and h(2 ... | 1972 | 4557561 |

| sensitivity of citrobacter freundii and citrobacter koseri to cephalosporins and penicillins. | an examination of 99 field and reference strains of citrobacter freundii showed 79% of them to be resistant to cephaloridine and sensitive to carbenicillin, while 96% of 45 field and reference strains of citrobacter koseri examined were sensitive to cephaloridine and resistant to carbenicillin. susceptibility tests with these two antibiotics are therefore useful in separating the two species of citrobacter. | 1974 | 4496972 |
