| taxonomic investigations on expressed and cryptic phospho-beta-glucosidases in enterobacteriaceae. | 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 ... | 1969 | 4897109 |

| comparative study of the efficacy of seven paper-reagent strips and conventional biochemical tests in identifying gram-negative organisms. | gram-nagative organisms were tested with commercially available reagentimpregnated strips (patho-tec). of the 291 strains, all were tested by using seven paper tests and their conventional counterparts. excellent correlation was obtained with the oxidase, phenylalanine-deaminase, and voges-proskauer tests. indole tests made on liquid medium cultures also gave complete correlation, but some false-negative results with indole-positive proteus strains were obtained when growth from solid medium was ... | 1969 | 4907007 |
| hydrogen sulfide-negative variant of citrobacter. | the characteristics of 25 hydrogen sulfide-negative strains of citrobacter were studied. the majority of isolates were from the respiratory tract and usually were of indeterminate clinical significance. all strains were highly susceptible to polymyxin b, gentamicin, kanamycin, nalidixic acid, and nitrofurantoin. | 1970 | 4925244 |

| comparison of the rates of motility of salmonella with those of other enteric bacteria. | comparison of the rates of motility through a semisolid medium of 16 common salmonella sp., 14 escherichia coli serotypes, 4 arizona strains, 2 escherichia freundii (citrobacter) isolates, 2 proteus sp., and 2 pseudomonas sp. revealed the following. (i) very closely related bacteria could demonstrate markedly different rates of progression. (ii) all of the salmonellae tested advanced faster than the proteus and pseudomonas test cultures but some salmonella sp., notably s. choleraesuis and s. typ ... | 1971 | 4926440 |
