Vibrio shiloi is the first and well-documented bacterium which causes coral bleaching, particularly, during summer, when seawater temperature is between 26 and 31 degrees C. Coral bleaching is the disruption of the symbiotic association between coral hosts and their photosynthetic microalgae zooxanthellae. This is either due to lowered resistance in corals to infection or increased virulence of the bacterium at the higher sea surface temperature. The concentration of the oxygen and resulting oxygen radicals produced by the zooxanthellae during photosynthesis are highly toxic to bacteria, which also assist corals in resisting the infection. Hence, in this study we examined the …

OBJECTIVE: Shigella dysenteriae Type 1 dysentery is a major cause of morbidity and mortality in children from less developed and developing countries. The present study explores the hypothesis that lactobacilli protect the host cell during S. dysenteriae Type 1 infection and its mechanism of action. METHODS: Caco-2 cells incubated for 1h with Lactobacillus rhamnosus or Lactobacillus acidophilus at the multiplicity of infection of 100, either alone or in combination followed by addition of Shigella at the same multiplicity of infection for 5h served as treatment groups. Cells incubated with Shigella without lactobacilli addition served as infected cells. At the end …
