| experimental observations on the pathogenesis of necrobacillosis. | earlier studies showed that the minimum infective dose (greater than 10(6) organisms) of a virulent strain of fusobacterium necrophorum could be greatly reduced by suspending the fusobacteria in sub-lethal doses of cultures of other bacteria such as escherichia coli before inoculating mice subcutaneously. in the present study the infective dose of the same strain of f. necrophorum was reduced by a factor of greater than 10(3) by suspending the fusobacteria in sub-lethal doses of 5% homogenate of ... | 1990 | 2307186 |
