The MICs of 21 antimicrobial agents were determined for 60 strains of Aeromonas spp. isolated from human feces. All isolates tested were susceptible to aztreonam, tetracycline, imipenem, moxalactam, pipemidic acid, gentamicin, trimethoprim-sulfamethoxazole, pefloxacin and ciprofloxacin. Resistance to erythromycin and streptomycin was observed in all 60 strains. Aeromonas caviae was less susceptible to cefamandole, cefotaxime, norfloxacin, chloramphenicol, tetracycline, sulfamethoxazole and trimethoprim than was either Aeromonas hydrophila or Aeromonas sobria. It was concluded that cotrimoxazole or one of the newer quinolones can be considered for treatment of aeromonas-associated diarrhea.

From July 1985 to March 1987, the occurrence of motile Aeromonas sp. in stool, food and environmental specimens was investigated to assess their pathogenic significance and to determine sources and routes of infection. A total of 9366 stool specimens were examined; Aeromonas was isolated from 11.1% of diarrhoeal stools and 2.2% of normal stools (P less than 0.001). Aeromonas counts in food specimens, which included minced beef, pork and chicken, seafood and various vegetables and their products, were unexpectedly high suggesting that infection might be food-borne rather than water-borne. About 70% of the isolates from meat products were A. hydrophila and A. sobria, while A. caviae was the most common in sea-fish, vegetables and their products. Most A. hydrophila and A. sobria strains produced haemolysin, but haemagglutinin was found more frequently in A. sobria.

“…Control wells without bacteria or monolayer cells were also prepared, as were wells with chloramphenicol 25 mg/L (MIC90 for A . caviae 8 mg/L) to stop bacterial protein synthesis [27]. Chloramphenicol was also used to stop protein synthesis for adherence assays when bacteria grown at 4, 12, 26 and 37°C were employed to investigate the effect of altering growth temperature.…”

Adherence of Aeromonas caviae to HEp-2 and Caco-2 cell monolayers was investigated with 24 clinical isolates. Growth phase, temperature, multiplicity of infection and length of incubation affected adherence. Treatment of the bacteria with trypsin, sodium metaperiodate, mechanical shearing and the addition of cytochalasin B and cycloheximide to the monolayer significantly reduced the adherence capabilities of the strains investigated. The use of chloramphenicol to inhibit protein synthesis reduced the adhesive capabilities of bacteria grown in liquid medium and those subjected to mechanical shearing. Light microscopy, scanning and transmission electron microscopy were employed in the investigation of bacteria-bacteria and bacteria-monolayer interactions and indicated similarities with the aggregative adherence patterns of the Enterobacteriaceae. The presence of extracellular bacterial appendages and their correlation with increased adhesive capacity may indicate a role in the process of adherence.
