Table 1.

Fluoroquinolone resistant isolates FRIs of E. coli with and without qnrB. Five E. coli isolates were analyzed from each fecal sample from either humans or chickens inhabiting rural communities in the northern coast of Ecuador.

Source of isolates	Number of isolates	FRIs %	FRIs with qnrB %	p-value
Human isolates from rural area	1,167	35 3.0%	11 31%
Human isolates from urban hospitals	ND^**	114	1 0.87%	p<0.0001
Broiler chicken isolates from rural area	961	214 22.3%	4 1.87 %
Household varietals from rural area	246	37 15%	3 8.1%
Broiler chicken isolates from an industrial poultry operation	827	81 9.8%	3 6.0%^***

Only 50 isolates were analyzed for qnrB genes. P value obtained from comparison of human isolates from the rural community and the hospital in Quito
