antibacterial activity of amifloxacin (win 49, 375), a new quinolone agent.the in vitro activity of amifloxacin, a quinolone antimicrobial agent was compared with those of ciprofloxacin, enoxacin, ofloxacin and norfloxacin against gram-positive and gram-negative bacteria. ninety percent of escherichia coli, klebsiella species, aeromonas, salmonella, shigella, citrobacter, enterobacter species, proteus mirabilis, serratia marcescens, and morganella morganii were inhibited by less than or equal to 0.5 microgram/ml. amifloxacin inhibited branhamella, haemophilus, and neis ...19854064609
aeromonas caviae: an enteric pathogen?of the aeromonas spp. isolated routinely in our laboratory from human feces, about two thirds represent aeromonas caviae. in contrast to aeromonas hydrophila and aeromonas sobria, this species has been considered to be of little enteropathogenic significance due to the absence of known virulence factors. the clinical data presented here suggest a clinical significance of a. caviae, at least in some cases. as yet nothing is known about the pathogenic mechanisms involved.19854066046
peritrichous flagella in mesophilic strains of aeromonas.a total of 186 mesophilic strains of aeromonas, comprising 151 a. hydrophila and 35 a. caviae, were tested for peritrichous flagella by leifson's staining method. when incubated on solid medium for 18 hr at 22 c, peritrichous flagella were demonstrated in 28 (18.5%) of the 151 strains of a. hydrophila and in 6 (17.1%) of the 35 strains of a. caviae. the peritrichous flagella in these 34 mesophilic strains of aeromonas were also observed by electron microscopy.19854068347
ticarcillin plus clavulanic acid versus moxalactam therapy of osteomyelitis, septic arthritis, and skin and soft tissue infections.a controlled, randomized study to compare the efficacy and safety of ticarcillin plus clavulanic acid with moxalactam was carried out in 25 evaluable patients with bone, joint, and skin or skin structure infections. of the 13 patients in the ticarcillin plus clavulanic acid-treated group, nine had osteomyelitis, two had septic arthritis, one had cellulitis, and one had a wound infection. four of the 12 moxalactam-treated patients had osteomyelitis, one had septic arthritis, and the other seven h ...19854073082
aeromonas-related diarrhea in adults.we have reviewed the incidence of aeromonas in patients with enteric disease at our hospital and found it to be the highest of any potential enteric pathogen. eighty adult patients with diarrhea had aeromonas isolated from feces, and in 73 aeromonas was the only potential bacterial or parasitic pathogen detected. the spectrum of illness in patients with aeromonas-related diarrhea ranged from acute, self-limited diarrhea to a chronic, indolent diarrheal illness. sixteen percent (13/80) of the pat ...19854074035
prevalence and pathogenicity of aeromonas hydrophila.a field survey to determine the prevalence of aeromonas hydrophila revealed a recovery rate of 8% in 141 specimens derived from a range of live, companion, and exotic avian species. the prevalence rate was similar in 240 sequential postmortem submissions during 1984. studies on the pathogenicity of a. hydrophila showed that 2-to-4-day-old chicks and turkey poults were highly susceptible to exposure via the subcutaneous, yolk-sac, and intracerebral routes, and mortality of 80-100% occurred within ...19854074237
spectral and kinetic studies of metal-substituted aeromonas aminopeptidase: nonidentical, interacting metal-binding sites.apoenzyme prepared by removal of the 2 mol of zn2+/mol from aeromonas aminopeptidase is inactive. addition of zn2+ reactivates it completely, and reconstitution with co2+, ni2+, or cu2+ results in a 5.0-, 9.8-, and 10-fold more active enzyme than native aminopeptidase, respectively. equilibrium dialysis and spectral titration experiments with co2+ confirm the stoichiometry of 2 mol of metal/mol. the addition of only 1 mol of metal/mol completely restores activity characteristic of the particular ...19854074699
antigen localization in the lymphoid organs of carp (cyprinus carpio).a brief morphological description is given of the spleen, head kidney and trunk kidney, the three peripheral lymphoid organs of carp. an antigen-localization study was carried out using aeromonas hydrophila (a cellular bacterial antigen) and an indirect immunofluorescence test. examination of the lymphoid organs at various times after injection (up to 12 months) showed that antigen was at first present in splenic ellipsoids and in solitary phagocytic cells in the spleen, head and trunk kidney. l ...19854075373

growth of aeromonas spp. on cefsulodin-irgasan-novobiocin agar selective for yersinia enterocolitica.twenty-eight strains of aeromonas spp. were analyzed for their ability to grow on two different kinds of cefsulodin-irgasan (triclosan; ciba-geigy ag, basel, switzerland)-novobiocin (cin) agar containing 15 or 4 mg of cefsulodin per ml and on inositol-bile salts-brilliant green (ibb) agar. relative to blood agar, 68% of the strains were inhibited by more than 2 logs (i.e., less than 1% growth) at 37 degrees c (39% at 25 degrees c) on cin i (high cefsulodin concentration), 7% were inhibited at ei ...19854077959
holding effects on coliform enumeration in drinking water samples.standard procedures for analyzing drinking water stress the need to adhere to the time and temperature conditions recommended for holding samples collected for microbiological testing. the national drinking water laboratory certification program requires compliance with these holding limits, but some investigators have reported difficulties in meeting them. research was conducted by standard analytical methods to determine if changes occurred when samples were held at 5 and 22 degrees c and anal ...19854083877
