TABLE 2.

Geographical distribution of resistant E. coli across 613 public restrooms in rural areas and city centers in Tainan.

	Rural area N = 283	City center N = 330	Total N = 613	P- value (Rural area vs. city center)
Numbers of sites with NS isolates found (% of numbers in rural area, city center, and total)
Cefazolin NS	28 (9.9)	23(7.0)	51 (8.3)	0.240
Ceftriaxone NS	11 (3.9)	4 (1.2)	15 (2.4)	0.038
Ceftazidime NS	11 (3.9)	4 (1.2)	15 (2.4)	0.038
Ciprofloxacin NS	5 (1.8)	3 (0.9)	8 (1.3)	0.481
TMP-SMX NS	28 (9.9)	19 (5.8)	47 (7.7)	0.067
Amoxicillin NS	20 (7.1)	10 (3.0)	30 (4.9)	0.024
Gentamicin NS	4 (1.4)	1 (0.3)	5 (0.8)	0.187

NS: not susceptible including resistant and intermediate.

Any collection site with one antimicrobial non-susceptible isolate was calculated. The number of intermediate (I) and resistant (R) in cefazolin: rural area: (15, 13); city center: (17, 6).

The number of intermediate (I) and resistant (R) in ceftriaxone: rural area: (2, 9); city center: (2, 2).

The number of intermediate (I) and resistant (R) in ceftazidime: rural area: (0, 11); city center: (1, 3).

The number of intermediate (I) and resistant (R) in ciprofloxacin: rural area: (2, 3); city center: (1, 2).

The number of intermediate (I) and resistant (R) in TMP-SMX: rural area: (0, 28); city center: (1, 18).

The number of intermediate (I) and resistant (R) in amoxicillin: rural area: (9, 11); city center: (4, 6).

All gentamicin NS isolates were resistant.

TMP-SMX, trimethoprim-sulfamethoxazole; ESBL, extended-spectrum β-lactamases; ST131, sequence type 131.
