A biochemical study of 141 strains of enterobacteriaceae isolated from tissues and fluids of animal origin

Abstract

The following tests were performed on 141 strains of Enterobacteriaceae isolated from a variety of animal tissue and fluid submitted for bacteriological examination: motility, acid production from glucose, mannitol, adonitol, dulcitol, inositol, lactose, salicin and sucrose, gas production from glucose, indole production, gelatin liquefaction, hydrogen sulphide production, methyl red and Voges-Proskauer test, urea hydrolysis, growth in potassium cyanide and Koser's citrate, and deamination of phenylalanine. The strains were grouped as Salmonellae 15, Arizona 2, Escherichia coli 19, Alkalescens-Dispar 8, Escherichia freundii 2, Bethesda-ballerup 13, Klebsiella ozaenae 3, Klebsiella pneumoniae 19, Klebsiella sp. 12, Cloaca 27, Providence 2 and ungrouped 19. The importance for further studies and pathogenicity assessment on lesser known strains of Enterobacteriaceae is stressed.
