[Urinary bacteriology in the elderly in the tropical zone: results of 5 years of activities at the CHU of Fann in Dakar].

: The authors report a retrospective account on 5 years (1987-1991) studied on 300 specimen of urine, coming from subjects aged 65 or more and having been submitted to bacteriologic examination in Dakar, Senegal (microscopic examination, counting, isolation, identification of bacteria, antibiotic tests). On the whole, 8150 samples of urine were recorded during the same period in the Laboratory of Bacteriology (CHU de Fann). The results obtained show a particular exposure of the old subjects to urinary tract infection (37%, against 23% in subjects aged less 65 years). The isolation of bacteria was not attached to sex. E. coli and Klebsiella sp. are the most frequently isolated in urine. The most efficacy antibiotics on these agents are the Cepholosporins, the Aminosids, Nitroxolin and Oxolonic Acid.
