“…The presence of a zone of complete lysis of erythrocytes around the colony and clearing of the medium on 5% sheep blood agar, is suggestive of α-haemolysin production. 8,9 Serum resistance was studied by using fresh overnight culture of isolates as per the method described by Sharma et al 9 The UPEC strains were considered serum sensitive if viable count dropped to 1% of the initial value and serum resistant if ≥90% of organisms survived after 180 minutes.…”

“…Most E. coli isolates reside harmlessly in the gastrointestinal tract of humans and animals as part of their normal microflora and benefit the hosts by producing key nutrients, such as vitamin K (Suvarna et al., 1998). Some isolates of E. coli are able to colonise sites outside the intestine and cause extraintestinal disease (Sharma et al., 2007). For example, E. coli is also recognised as a major cause of urinary tract infections (UTIs) that can lead to the development of acute cystitis and pyelonephritis (DeCory et al., 2005).…”
