INVESTIGATION OF UTI IN PREGNANCY
This study investigates the bacteriological aetiology and Urinary Tract Infections (UTIs) among pregnant women attending antenatal clinics at hospitals in Enugu metropolis.70 mid-stream urine samples were collected and cultured for the presence of bacterial pathogens, 38 of which showed significant bacterial growth while the remaining 32 showed no significant bacterial growth.
Bacterial agents were isolated from 38 pregnant women and were identified as: Escherichia coli; Klebsiellaspp., Proteus mirabilis, Pseudomonas aeruginosa, Staphylococcus aureusand Staphylococcus epidermidis. Escherichia coli 15(39.5%)was the commonest offending bacterial pathogen isolated. Other bacterial pathogens incriminated in this study were Klebsiellaspp. 9 (23.7%), Proteus mirabilis 6 (15.8%), Pseudomonas aeruginosa4(10.5%), Staphylococcus aureus2 (5.3%) and Staphylococcus epidermidis2 (5.3%). The study indicated a low incidence of Urinary tract infections(38.0%),though most of the pregnant women showed no clinical manifestation.

1.1 URINARY TRACT INFECTIONS
Urinary Tract Infections (UTIs) are associated with multiplication of organisms in the urinary tract. UTI defined as the microbial invasion of any of the tissues of the urinary tract extending from the renal cortex to the urethral meatus (DelzellandLefevre, 2000). The urinary tract includes the organs that collect and store urine and release it from the body which include: kidneys, ureters, bladder, urethra and accessory structures. Urine formed in the kidney is a sterile fluid that serves as a good culture medium for proliferation of bacteria (Omonigho et al., 2001). UTI is evident by the presence of 105 microorganisms or of a single strain of bacterium per ml in two consecutive midstream samples of urine (Davidson et al.,1989). UTI could be described based on the part of the tract affected, for upper tract it is called Pyelonephritis and the lower part, cystitis (Stamm, 1998).
