further use of deoxyribonuclease in a screening test for serratia.the deoxyribonuclease (dnase) test is useful in classifying serratia bacilli and in differentiating it from the hafnia group, e. cloacae, and e. liquefaciens. it is recommended as a differential test in enteric bacteriology because of its specificity, the convenience of its use, and the rapidity with which it can be performed.19684880362
taxonomic investigations on expressed and cryptic phospho-beta-glucosidases in the enterobacteriaceae, beta-glucosides are catabolized by a complex system formed of three permeases, with partly overlapping substrate specificities, and two hydrolytic enzymes, phospho-beta-glucosidase a and b, which hydrolyze only phosphorylated beta-glucosides. some enterobacteriaceae such as klebsiella-aerobacter (enterobacter) possess the complete system; others possess only parts of it or may have a cryptic phospho-beta-glucosidase activity without permease activity. a screening test ...19694897109

retardation of wool growth in merino sheep caused by bacteria.a condition evidenced by retarded growth of wool with alteration of the yolk into a yellow, sticky, wax-like substance was investigated. the condition was associated with hyperaemia and cellular infiltration into the dermis in the affected areas. three bacterial species, viz. enterobacter aerogenes, e. agglomerans and hafnia alvei, which could grow on the water-extractable component of wool-yolk, were incriminated as the cause of the condition.19836676689
[influence of hemolytic plasmids on the development of the "killing" effect in various species of enterobacteria].experiments on isogenic strains of different enterobacterial species, both carrying hemolytic plasmids and free from them, have demonstrated that their "killing" effect on mice is linked with the yield of hemolysin and does not depend on the origin of hly plasmids or the chemotype of bacteria. plasmid p ie 567 coding the synthesis of alpha-hemolysin has been shown to be capable of expression in enterobacter aerogenes, hafnia alvei and salmonella typhimurium strains, but e. aerogenes 3/43, h. alv ...19836356727
[study of lincomycin concentrations in hepatocystic duct].penetration of lincomycin (lcm) in choledochal and cholecystic bile as well as in the gallbladder tissue and liver tissue was investigated together with bacteria detectable in the bile in order to evaluate basically usefulness of this antibiotic in the treatment of infections of the hepatocystic duct. intravenous drip infusion of lcm 1.5 g (in 500 ml of 5% glucose solution) over 1.5--2 hours resulted in mean drug concentrations of 33.9 and 10.1 micrograms/ml in serum at 2 and 4 hours post start ...19846502929
