Abstract
- Members of the Bacillus cereus group demonstrate different pathological effects. B. cereus is a spore-forming, gram positive bacterium responsible for most foodborne illnesses. It was shown that susceptibility to infection and response to vaccines or treatments can be attributed to specific immunogenetic factors including gender and ethnicity. Glycoconjugate polymers (GCs) are potentially important in pharmaceutical and biomedical research. Our group has shown that GCs activate murine macrophages and promote killing of Bacillus cereus spores during phagocytosis. We hypothesized that the GCs effects are independent from gender and race. The goal of the present study was two-folds: A) determine whether GCs influence on human PMNC exposure of B. cereus spores and B) analyze whether gender and ethnicity influence of the effect of GCs. GCs were studied during exposure and post-exposure conditions. Phagocytosis was performed during exposure of PMNC to Bacillus spores. Post-exposure analysis involved cytotoxicity, cell viability and activation, and colonies forming unit. GC1 and GC3 enhance Bacillus spore killing. GC1 proved more effective than GC3 in spore killing while activating PMNC. Results demonstrate GCs effect were independent from ethnicity or gender. Findings of this research demonstrated that GC can be used as ligands to stimulate PMNC and kill B. cereus spores. [ABSTRACT FROM AUTHOR]
