	Acute	Chronic
Gastric	2	3
Non-gastric	5	5

Table 2 Prevalence of Helicobacter spp. and some common gut bacteria n (%)

Patient group	Helicobacter PCR	Gut bacteria PCR	Sequencing results (No. of samples)
Acute cholecystitis	4/50 (8)	0/50 (0)	H. pylori (1)
			H. pullorum (3)
Chronic cholecystitis	3/50 (6)	0/50 (0)	H. pullorum (3)
Controls	0/102 (0)	0/102 (0)	-

Results are shown as the number of positive patients and the number of all patients in the group followed by the percentage in parenthesis. PCR: Polymerase chain reaction; H. pylori: Helicobacter pylori; H. pullorum: Helicobacter pullorum.
