| genetics of sensitivity of salmonella species to colicin m and bacteriophages t5, t1, and es18. | nearly all of 62 strains of salmonella paratyphi b were sensitive to colicin m and phage t5 but resistant to phages t1 and es18 and to colicin b. all tested s. typhimurium strains were resistant to colicin m and phage t5, and many were sensitive to phage es18. a rough s. typhimurium lt2 strain given the tona region of escherichia coli or s. paratyphi b became sensitive to colicin m and phage t5. we infer that the tona allele of s. paratyphi b, like that of e. coli, determines an outer membrane p ... | 1977 | 324978 |

| polyclonal activation of human peripheral blood b lymphocytes by formaldehyde-fixed salmonella paratyphi b. i. immunoglobulin production without dna synthesis. | a "new" polyclonal activator of human peripheral blood b cells, formaldehyde-fixed salmonella paratyphi b, is described. this bacterium does not stimulate cell proliferation as measured by incorporation of tritiated thymidine but does stimulate a subpopulation of b cells to secrete large amounts of igm, igg, and iga in 7-day cell cultures. the immunoglobulins (ig) produced by cells responding to s. paratyphi b are not specific antibodies against the bacterial antigens. in comparison with other b ... | 1981 | 6972434 |
| polyclonal activation of human peripheral blood b lymphocytes by formaldehyde-fixed salmonella paratyphi b. ii. heterogeneity of b lymphocytes. | b-cell 'activation' in cultures stimulated with pokeweed mitogen (pwm), staphylococcus aureus strain cowan i, or formaldehyde-fixed salmonella paratyphi b (spb) was evaluated by enumeration of cells secreting immunoglobulin (ig) and by quantitation of ig released into culture supernatants. a dissociation between these two values was found after day 6 in cultures activated with pwm or spb, suggesting that ig-secreting cells (isc) are heterogeneous in terms of ig secretion rate. generation of isc ... | 1982 | 6979775 |

| [current epidemiological status of salmonellosis of humans in germany]. | infections caused by salmonella typhi and salmonella paratyphi b have special epidemiological significance. however, the enteritis caused by salmonella enteritidis and salmonella typhimurium dominates. a complex typing of these serovars is the prerequisite for both, an effective surveillance of salmonellosis and the detection of occurring replacements and variations of the pathogens. the increasing occurrence of salmonella in spices since 1993 is epidemiologically remarkable. in this connection, ... | 1994 | 7927464 |
