These host cells are generally M cells and Peyer’s patches of the intestinal mucosa. The same mechanism also allows the bacteria to travel from cell to cell.

Listeria, Listeriosis, and Food. The responsible bacterium, infantoseptica Streptococcus agalactiae, may be found most often in the vagina and rectum of females and may be transmitted as the infant passes through the birth canal. Gastrointestinal symptoms, such as nausea, vomiting, and diarrheamay precede more serious forms of listeriosis or may be the only symptoms expressed. Pathogen, host and environmental factors contributing to the pathogenesis of listeriosis.

Symptoms secondary to these conditions depend on the anatomical site of infection infantispetica may include abdominal pain, bone pain, respiratory distress, pneumonia, and heart failure. Together we are strong.
