Effect of light on the cultivability of different Helicobacter and Campylobacter spp. at 25°C^a

Condition	Mean area (log CFU·h/ml) ± SD for:
	H. pylori NCTC	H. pylori 1330	C. jejuni 1.2	H. mustelae 2H1	H. canis	H. felis
Absence of light	459.1 ± 33.3	284.8 ± 30.2	301.4 ± 8.7	153.9 ± 17.3	142.2 ± 15.5	16.2 ± 4.5
Presence of light	83.1 ± 17.1	88.3 ± 2.6	61.5 ± 9.5	84.2 ± 20.3	81.6 ± 5.4	10.9 ± 5.0

^aData represent the values of the area under the curve of cultivability over time as calculated by the trapezium rule. The cultivability of the strains in water when exposed to light over time is shown in Fig. SA2 in the supplemental material.
