Alterations in gut morphology of mice. Representative macroscopic images for the gross morphological alterations of the small intestine and caecum from mice at 24 h of treatment. (A) Small intestine Black arrows indicate normal small intestine in the uninfected group (blue arrowhead) indicate normal caecum. (B) White arrows point to injury in small intestine in the infected and untreated group (blue arrow) shows caecum is swelling. (C) Black arrows indicate injury in small intestine (blue arrows) caecum is swelling and enlarged in the tetracycline group. (D) Black arrows indicate normal small intestine as in A (blue arrowhead) indicates normal caecum. (E) Black arrows indicate normal small intestine in the LFchimera group as in D (blue arrow) indicate caecum.
