TABLE 2.

Density of active bacteria colonizing the adjacent intact intestine and the subsections of the intestinal segment remaining either isolated or reconnected to the adjacent small intestine of neonatal lambs during the first 2 months of life.

Bacterial density*	Day 1		Day 7			Day 56			SEM	P-value
	Adjacent	Isolated	Adjacent	Isolated	Reconnected	Adjacent	Isolated	Reconnected		PS	PT	PS*T
Total bacteria	10.3a	9.7b	10.5a	9.7b	9.5b	10.4a	9.8b	10.3a	0.17	0.01	0.78	< 0.01
Bifidobacterium	8.9a	6.9b	8.9a	6.5b	6.4b	8.6a	6.5b	7.3c	0.19	< 0.01	0.10	0.02
Lactobacillus	7.3a	6.3b	7.6a	5.6b	6.1b	7.2a	6.3b	6.9ab	0.20	< 0.01	0.04	0.02

^*Bacterial density is presented as log₁₀ 16S rRNA copy/g of intestinal samples. ^a,b,cThe presence of a different superscript indicates that bacterial densities are differed at P < 0.05. P_S, effect of intestinal segment; P_T, effect of timepoint; P_S*Teffect, of intestinal segment by timepoint interaction.
