bacteremia in patients with cirrhosis of the liver.infections are frequent in patients with liver cirrhosis, as their defenses against infectious agents are altered. but bacteremia occurring in cirrhotic patients has seldom been reported in the literature. from 1981 to 1986, we collected 197 cases with 228 episodes of bacteremia for this retrospective study. the incidence of bacteremia in cirrhotic patients was 8.8%; no significant difference was noted between cirrhotic patients with variant etiologies of hbv(+), hbv(-) and alcohol. but the inci ...19911779712

in vitro and in situ survivals of bacterial populations added to fresh water environments.the fate of aeromonas hydrophila, alcaligenes denitrificans, vibrio cholerae non-01, pseudomonas putida and four different isolates of escherichia coli in fresh river water were assessed by using different microcosms (i.e., membrane diffusion chamber and erlenmeyer flask). when water samples were incubated at 16 +/- 1 degrees c, the differences in extent of survival among test bacteria were in general not significant. if the incubation temperature was raised to 29 +/- 1 degrees c, in the in situ ...19937982366
increasing antibiotic resistance in clinical isolates of aeromonas strains in taiwan.a total of 234 clinical isolates of aeromonas, primarily a. hydrophila, were collected for the present study. most were isolates from blood. by the agar dilution method, more than 90% of the aeromonas strains were found to be susceptible to moxalactam, ceftazidime, cefepime, aztreonam, imipenem, amikacin, and fluoroquinolones, but they were more resistant to tetracycline, trimethoprim-sulfamethoxazole, some extended-spectrum cephalosporins, and aminoglycosides than strains from the united states ...19968723478

Bacteremia due to extended-spectrum-ß-lactamase-producing Aeromonas spp. at a medical center in Southern Taiwan.Although extended-spectrum-ß-lactamase (ESBL)-producing aeromonads have been increasingly reported in recent years, most of them were isolates from case reports or environmental isolates. To investigate the prevalence of ESBL producers among Aeromonas blood isolates and the genes encoding ESBLs, consecutive nonduplicate Aeromonas blood isolates collected at a medical center in southern Taiwan from March 2004 to December 2008 were studied. The ESBL phenotypes were examined by clavulanate combinat ...201121968366
bacteriology of naja atra snakebite wound and its implications for antibiotic therapy.a total of 112 cases of naja atra envenomation were examined at two referring hospitals: taichung veterans general hospital in central taiwan and taipei veterans general hospital (vgh-tp) in northern taiwan. overall, 77% (86/112) of cases developed clinically suspected wound infections and 54% (61/112) required surgery secondary to tissue necrosis, finger or toe gangrene, and/or necrotizing fasciitis. morganella morganii was the most abundant gram-negative bacterial strain isolated from bite wou ...201626976881
