5 years of bacteriological analysis. Results and observations [Un quinquennio di analisi batteriologiche. Risultati ed osservazioni.]

The Authors examined the bacteriological analysis carried our during a period of five years (June 1971-June 1976), and pointed out the percentage of positivity and sensibility to antibiotics of the bacteria isolated. On a total of 8,263 analysis, 4,327 coprocultures and 2,076 urinocultures have been made, thus occupying the first places in frequency. 195 patogenous enterobacteria have been isolated from coprocultures, corresponding to a positivity of 4.50%. As for the urinocultures positivity reached 43.25%; the germs most frequently isolated were Escherichia coli and Proteus mirabilis. The Authors isolated in the same period 17 strains of Myc. tuberculosis from 115 samples of expectoration (14.7%) and 27 strains from 216 samples of urine (12.5%). By recommending antibiograms, the Authors suggest that the most effective antibiotics against enterobacteria responsable of infections of the urinary and gastrointestinal tract are nalidixic acid and furadantin, cloramfenicolo was ineffective against the isolated Salmonella strains. As for Gram-positive germs some results have been obtained with cefalotine, rifampicin, and cefazolin.
