The Use of Two Culturing Methods in Parallel Reveals a High Prevalence and Diversity of Arcobacter spp. in a Wastewater Treatment Plant

Table 3

Number of Arcobacter spp. strains recovered depending on aerobic (A) and microaerophilic (MA) incubation conditions.

	Total recovered (%)	Only A (%)	Only MA (%)	A & MA (%)
A. butzleri	170 (60.7)	75 (58.6)	83 (65.4)	12 (48.0)
A. cryaerophilus	94 (33.6)	50 (39.1)	39 (30.7)	5 (20.0)
A. thereius	9 (3.2)	2 (1.6)	2 (1.6)	5 (20.0)
A. skirrowii	4 (1.4)	0	1 (0.8)	3 (12.0)
A. ellisii	2 (0.7)	1 (0.8)	1 (0.8)	0
A. cloacae	1 (0.4)	0	1 (0.8)	0
	280	128 (45.7%)	127 (45.4%)	25 (8.9%)

species A. defluvii and A. nitrofigilis do not appear at the table because they were isolated in 2009 where only aerobic incubation conditions were employed.
