Colony counts of streptomycin-resistant EAEC strain EN1E-0007 in faecal culture after 16 h incubation at 37 °C

Treatment	Faeces (c.f.u. ml−1)	Faeces+EAECc (c.f.u. ml−1)
Neat	0	9.0×107
PDX a	0	1.7×103
Ciprofloxacinb	n/a	0

Human faecal samples were collected and cultured anaerobically under the following regime: faeces only, faeces+EAEC, faeces+EAEC+ciprofloxacin, faeces+EAEC+PDX and faeces+PDX. Each challenge was cultured in triplicate.

a, Cultures were inoculated to 4.0x 10⁵ p.f.u. ml⁻¹ PDX for an m.o.i of 100.

b, Cultures were inoculated to 25 μg ml⁻¹ ciprofloxacin.

c, Cultures were inoculated to 4.0x 10 c.f.u. ml⁻¹ EAEC isolate EN1E-0007.
