murine toxicit of agrobacterium tumefaciens. | eleven strains of the crown gall organism, agrobacterium tumefaciens, tested by intraperitoneal injection into mice, were lethal within 48 hr. five other species had some lethal strains. the lethal effect of a. tumefaciens appeared to be the result of a toxic rather than an infectious process, since histopathological anomalies were not found in mice injected with live cultures and since heat-killed cultures were lethal. the murine toxin disappeared when a. tumefaciens was grown at 36 c and reapp ... | 1968 | 5643064 |
thermostability of antigens associated with serotype of rhizobium japonicum. | the antigens associated with serologically distinct strains of rhizobium japonicum were found to differ in heat sensitivity. cell preparations from 4 out of 12 strains retained agglutinability, and 1 out of 5 retained antigenicity after they were heated to 120 c. antigenicity was reduced in most strains after heating to 100 c for 30 min, but agglutinability was not affected by this treatment. this suggests that the antigens are protein-polysaccharide-lipid complexes described for o-type antigens ... | 1968 | 5645406 |

populations of dalapon-decomposing bacteria in soil as influenced by additions of dalapon or other carbon sources. | the numbers of bacteria capable of decomposing the herbicide dalapon were determined for five soils by the most-probable-number method. before treatment of the soils with dalapon, the numbers varied from 1,000 to 10,000 cells per g of soil. incubation of the soils with dalapon resulted in large increases (100-fold) in two of three soils in which dalapon was decomposed rapidly. lack of increase in numbers in spite of rapid decomposition in the other soil probably indicated breakdown by a chemical ... | 1969 | 5772393 |
bacterial attachment to a specific wound site as an essential stage in tumor initiation by agrobacterium tumefaciens. | the number of tumors initiated by agrobacterium tumefaciens strain b6 on primary pinto bean leaves was decreased when cells of an avirulent strain (iibnv6) were included in the inoculum. with sufficient b6 cells to initiate ca. 50% of the maximal number of tumors per leaf, inhibition was detected at a 1:1 ratio of b6 to iibnv6 cells and increased linearly with the logarithm of the number of iibnv6. varying the number of b6 in the presence of a constant number of iibnv6 or varying the number of b ... | 1969 | 5773014 |
bacteriophage release in a lysogenic strain of agrobacterium tumefaciens. | bacteriophage release in a lysogenic strain of agrobacterium tumefaciens v-1 is temperature-sensitive. at 25 c and 30 c, phage was released in a ratio of 1 plaque-forming unit per 100 bacteria; at 35 c, although bacterial growth was not inhibited, phage release was suppressed. phage synthesis was induced by heat shock, 42 c for 30 min, ultraviolet irradiation, and mitomycin c. induction by ultraviolet light was unusual-an immediate rise in phage titer followed irradiation. a large increase occur ... | 1969 | 5774138 |
