Aeromonas hydrophila isolated from food and drinking water: hemagglutination, hemolysis, and cytotoxicity for a human intestinal cell line (HT-29)
Article Abstract:
Aeromonas hydrophila-mediated hemolysis takes place more in water isolates than in food isolates, whereas hemagglutination is more frequent in food isolates than in water isolates. Cytotoxicity of the bacterium is equally prominent in food and water isolates. These results are based on a study for the pathogenicity of Aeromonas hydrophila in the erythrocytes of human intestinal cell line (HT-29) and six other cells. Findings suggest that use of the HT-29 cells is effective for studying the enteropathogenicity of the bacterium for humans.

Infection of Tetrahymena pyriformis by Legionella longbeachae and other Legionella species found in potting mixes
Article Abstract:
A study was conducted on the ability of the environmental and human wild-type strains of Legionella longbeachae and other Legionella species to infect Tetrahymena pyriformis (T. pyriformis). Some Legionella isolates from humans were unable to infect T. pyriformis, showing the lack of a relationship between human and Tetrahymena infections. Researchers are reminded that strain variabilities, food and other ambiguous factors affect the susceptibility of T. pyriformis.

Influence of growth mode and sucrose on susceptibility of Streptococcus sanguis to amine fluorides and amine fluoride-inorganic fluoride combinations
Article Abstract:
Research was conducted to examine the effects of sucrose and growth mode on susceptibility of Streptococcus sanguis to amine fluorides and amine fluorides and inorganic fluoride combinations to determine the relative importance of each factor. S. sanguis NCTC 10904 was used in all the experiments. The differences in susceptibility of biofilms and planktonic cultures have been attributed to several causes including bacterial growth rate and pH.
