ABSTRACT
We investigated the bacteriology of urinary calculi in relation to urinary tract infection, stone formation, chemical composition and antibiotic sensitivity. Fifty-two patients (37 males, 15 females) with urolithiasis were studied. Urine, serum and urinary calculi specimens were taken and serum biochemical tests to detect uric acid, calcium and phosphorus were performed. Urine analysis and culture were also performed. Of the 52 patients, 19 (37%) had associated urinary tract infection, with Escherichia coli and Proteus mirabilis being the most common causative microorganisms. The bacterial isolates from urine and those from calculi differed in their susceptibility to antimicrobial agents. We conclude that in over 50% of patients with urolithiasis, urine culture can detect the infecting organisms associated with stone formation and the organisms within urinary calculi.

We investigated the bacteriology of urinary calculi in relation to urinary tract infection, stone formation, chemical composition and antibiotic sensitivity. Fifty-two patients [37 males, 15 females] with urolithiasis were studied. Urine, serum and urinary calculi specimens were taken and serum biochemical tests to detect uric acid, calcium and phosphorus were performed. Urine analysis and culture were also performed. Of the 52 patients, 19 [37%] had associated urinary tract infection, with Escherichia coli and Proteus mirabilis being the most common causative microorganisms. The bacterial isolates from urine and those from calculi differed in their susceptibility to antimicrobial agents. We conclude that in over 50% of patients with urolithiasis, urine culture can detect the infecting organisms associated with stone formation and the organisms within urinary calculi

Seventy (70) appendiceal specimens and 80 ice-cream samples were analysed to detect Yersinia enterocolitica using three different media. Both Y. enterocolitica and Citrobacter freundii were recovered in appendiceal specimens (17.1% and 8.6%) and ice-cream (26.25% and 18.75%) respectively. Thioglycollate medium was more selective and productive in isolating Yersinia. Y. enterocolitica was the major causative agent of acute appendicitis (11/25, 44%). It was sensitive to chloramphenicol, gentamicin, tetracycline and trimethoprim- sulfamethoxazole.

Serum iron, serum total iron binding capacity and tranferrin saturation levels were measured in 45 infants, of whom 19 had urinary tract infections confirmed by positive suprapubic aspiration. The control group comprised 26 healthy infants with negative results. Mean serum iron and transferrin saturation values were significantly lower in infants with urinary tract infection compared with the control group (P < 0.01 and P < 0.001 respectively), especially if the cultured organism was Escherichia coli (P < 0.01, P < 0.02). Total iron binding capacity was within the normal range. We conclude that iron deficiency is not a major factor in the etiopathogenesis of urinary tract infection in Libyan infants.
