Examination of the Anaerobic Growth of Campylobacter concisus Strains

Table 2

CFU of C. concisus strains cultured under Anaero^H2+ and Anaero^H2− conditions.

Strain	Anaero^H2+ CFU	Anaero^H2− CFU
P1CDO-S1	517 ± 23.6	0.863 ± 0.061
P1CDO-S2	328 ± 25.5	0.813 ± 0.0318

P7UCO-S1	311 ± 105	9.42 ± 0.118
P13UCO-S3	111 ± 2.12	6.50 ± 0.707
P3UCB-S1	146 ± 36.8	1.57 ± 0.330
H3O-S1	73.8 ± 15.9	9.50 ± 1.91

The values (means ± standard deviation) were from triplicates. CFU: (colony forming unit) × 10⁸/mL. The CFU numbers of all 12 strains grown under Anaero^H2+ conditions were significantly higher than those of the respective strains grown under Anaero^H2− conditions (). Strains P1CDO-S1, P1CDO-S1, P2CDO-S1, P4CDO-S1, P6CDO-S1, and P8CDO-S1 were oral strains isolated from patients with CD. Strains P3UCO-S1, P7UCO-S1, and P13UCO-S3 were oral strains isolated from patients with UC. Strain P3UCB-S1 was an enteric strain isolated from intestinal biopsies of a patient with UC. Strains H3O-S1 and H5O-S1 were oral strains isolated from healthy controls.
