Intestinal and lung tissues collected from mice exposed to virulence factors from NE- or LE-E. faecalis. A Intestine and lungs collected from control (green) and LE-LTA-exposed (blue) mice. B Intestine tissues from LE-LTA-exposed mice depicting ulcerated nodules on the surface (red circles). C, D Haematoxylin-eosin staining of lung and intestine tissue samples. Red boxes indicate C collapsed alveoli and loss of the lung septum, as well as D cleaved and broken intestinal villi, with a reduced number of cupped cells. Scale bar: 200 × magnification. Abbreviations: ECP, extracellular product; LE, pathological; LTA, lipophosphatidic acid; NE, normal; SP, surface protein
