Bacteriological study of urine of 350 apparently healthy children who were divided into groups according to the various stages of childhood ago. In each study urine sediment , gram staining and the qualitative and quantitative culture was performed. The study revealed three maximum sediment leukocytes per microscopic field in 12.3 % of things and 1-2 erythrocytes per field in 6.28 %. No clear cylinders or inflammatory cells were observed . QRAM by coloring germs no sediment or total urine were detected. The qualitative culture was positive in 58% of cases have been isolated most often staphylococcus , coli and Klebsiella . However, quantitative culture revealed that the germ count did not exceed the threshold of 5 x 103, and that most cases ( 71 % ) had less than 1,000 bacteria per ml. , Or that were merely contaminants. This shows the importance of quantitative culture to differentiate ...

The urine of 500 children with various disease processes is studied. The samples were obtained directly, without using the catheter and the study of sediment, gram staining and quantitative culture was performed. Is proposed according to the distribution of bacterial counts , relating to the clinical picture and the study of sediment which significant bacteriuria horn to over 15,000 germs per ml is considered figures . According to this concept, of the 500 cases studied , 147 ( 29.4 %) were positive, with a greater incidence among newborns and infants s between school and pre - school . As for sex , between 0 and 2 years, the proportion of positivity was higher in men ; between 2 and 5 years , and was virtually unchanged between 5 and 12 years was higher in women. The most striking symptoms that prompted the request for examination , were fever , vomiting and diarrhea , which were more f...
