Figure 5. Transfer of ASF leads to a reduction in urease activity and fecal ammonia levels.

Figure 5

(A) Urease activity in the feces of a conventionally housed mouse versus a mouse treated with ABX and a mouse colonized with ASF. (B) In vivo urease activity in conventionally housed (n = 5) and ASF-colonized mice (n = 5) quantified by the release of 13CO2 after i.v. injection of 13C-urea. (C) Fecal urease activity at the indicated time points after transplantation of ASF into prepared mice fed an irradiated diet (n = 3). (D) Fecal ammonia levels before and after transplantation of ASF into prepared mice fed a nonirradiated diet (n = 5). *P < 0.01; **P < 0.001. Tukey’s test for multiple comparisons.
