Number of colonic intraepithelial (IE) and lamina propria (LP) immune cells before, during and after Campylobacter infection

Cell type	Before infection	During infection	After infection		Controlsc 95% confidence interval
			2 months	4 months
Leucocytes in LPa	69	268	102	199	81-118
Leucocytes in IEb	110	224	162	150	78-115
Lymphocytes in LPa	3	39	2	2	0-5
Lymphocytes in IEb	1	6	7	8	0-2

Quantifications of cells were conducted in ten randomly chosen fields using the Olympus CellSense software.

^aNumber of cells per field.

^bNumber of cells per mm² of epithelium.

^cThe control group comprised 27subjects (16 females and 11 males; mean age 52 years, range 20–69 years) who had submitted to colonoscopy for the following reasons: gastrointestinal bleeding, where the source of bleeding was identified as haemorrhoids (n=18), or angiodysplasia (n=2), and health worries resulting from a relative being diagnosed with colon carcinoma (n=7).
