Abstract
Urinary Tract Infection (UTI) is among the most community infections worldwide. Host factors such as patients age and gender may influence the prevalence of the infection. In this study a total of 186 urine samples from patients) 1–79 years( whom attended Azady Teaching Hospital at Kirkuk province, for UTIs disorders, were examined microscopically and cultured on suitable medias .The age group which were significantly more infected was 20 – 40 years with rate 21.1-34.9 %. The most common bacteria was Escherichia coli with rate of 60.3, 42.3% for each of females and males respectively. Followed by Staphylococcus aureus and Pseudomonas aeruginosa. Among 13 antibiotics used for sensitivity test S. aureus and K. pneumonia were more resistance comparing with other bacteria, they were resistant to 6 antibiotics, followed by Streptococcus sp. which was resistant for five antibiotics. Proteus mirabilis was resistant for four antibiotics, each of E. coli, P. aeruginosa and Serratia sp. were resistant for only three antibiotics. The majority of isolates were sensitive to tobramycin ceftizoxime and ntrofurantion, followed by chloramphenicol and ampcillin.whereas, high level resistance was seen to augmentin amoxicillin and nalidixic acid.
Pus, epithelia and R.B.C cells were more seen in samples infected with E. coli with rate of 80.3, 83.6, 45.9 % for each type of cells respectively, followed by S. aureus and P. aeruginosa. The most urine crystals was appeared in urine samples of patients infected with E. coli followed by P. aeruginosa K. pneumonia S. aureus. In urine samples with specific gravity 1.020 – 1.025 the most crystals seen was calcium oxalate followed by amorphus urate, calcium phosphate , while in urine samples with specific gravity 1.030 the only crystal seen was calcium carbonate . The PH of most urine samples were acidic (5.0 – 5.5, 6.0 – 6.5) with rate of 56.5, 43.5 % for each PH respectively. The PH of 70.5 % of the samples were acidic and 29.5% of them were 8.0 – 8.5. Calcium oxalate, amorphus urate and uric acid were seen in acidic urine samples, while in alkaline one calcium carbonate, calcium phosphate, triple phosphate and amorphus phosphate were seen.
