Detection and characterization of the hemolysin genes in Aeromonas hydrophila and Aeromonas sobria by multiplex PCR.
A multiplex PCR assay was designed to amplify the Aeromonas hydrophila and A. veronii bv. sobria hemolysin and aerolysin genes. The assay was evaluated by using 121 clinical isolates and 7 reference strains of Aeromonas spp., and these were divided into five genotypes on the basis of the results of the multiplex PCR. The five genotypes were characterized as type 1 for those carrying the ahh1 ge...
متن کاملPurification and characterization of cytolytic toxins produced by Aeromonas hydrophila and Aeromonas veronii biotype sobria strains.
Cytolytic toxins produced by Aeromonas hydrophila and Aeromonas veronii biotype sobria strains were partially purified from culture filtrates by two steps of purification: ammonium sulfate precipitation and hydrophobic chromatography using Phenyl-Sepharose CL-4B. Hemolytic activity was detected in one or two peaks in elution profile. Purified toxins were also cytotoxic to Vero and CHO cells. Mo...
متن کاملIn vitro susceptibilities of Aeromonas hydrophila, Aeromonas sobria, and Aeromonas caviae to 22 antimicrobial agents.
MICs of 22 antimicrobial agents for 60 strains of three Aeromonas species were determined by a microdilution method. The newer cephalosporins such as moxalactam, cefotaxime, and cefoperazone, the aminoglycosides, and chloramphenicol, tetracycline, nitrofurantoin, and trimethoprim-sulfamethoxazole inhibited most of the strains studied. Within the genus, A. hydrophila was more resistant than eith...
متن کاملIdentification of hydroxy fatty acids in Aeromonas hydrophila, Aeromonas sobria, and Aeromonas caviae.
Gas-liquid chromatographic analysis of fatty acid methyl esters obtained from clinical isolates of Aeromonas hydrophila, A. sobria, and A. caviae revealed the presence of two hydroxy fatty acid species, 3-OH 12:0 and 3-OH 14:0.
متن کاملDifferent Clinical Characteristics Among Aeromonas hydrophila, Aeromonas veronii biovar sobria and Aeromonas caviae Monomicrobial Bacteremia
This study aimed to compare the clinical presentations of Aeromonas hydrophila, A. veronii biovar sobria and A. caviae monomicrobial bacteremia by a retrospective method at three hospitals in Taiwan during an 8-yr period. There were 87 patients with A. hydrophila bacteremia, 45 with A. veronii biovar sobria bacteremia and 22 with A. caviae bacteremia. Compared with A. hydrophila and A. veronii ...
