  Salmonella enterica serovar typhimurium is a facultative anaerobic bacterium, gram-negative, flagellated which generally develops and grows preferably in a wide variety of tumor cells. Until now, several factors for this predilection have been described, such as: an increase in number of nutrients favorable for bacterial growth due to rapid growth of the tumor cells, adaptation of S. typhimurium, loss of macrophages and neutrophils bactericidal activity in areas of hypoxia, the absence of antibodies and complement factors around the tumor. This study analyzed the infection in vitro of Salmonella enteritidis serovar typhimurium in A549 cell lineage, in three different aspects: morphological characterization of the infection, analysis of cellular DNA degradation and production of cytokines such as TNFα. The morphological assay showed tumor cell shrinkage, nuclear fragmentation wit.. View More»
