Table 4

Multiple-drug resistant (MDR)* pattern of E. coli isolates determined by Kirby-Bauer agar disc diffusion method and mean zones of inhibition compared with the values provided by the Clinical and Laboratory Standards Institute [7].

Hospital	Total No. of MDR E. coli	Total no. of; E. coli isolates	Percent of MDR
Tafo	27	30	90
Suntreso	28	34	82.4
Kumasi-South	23	33	69.7
Total	78	97	80.4
