Cloning and expression in Escherichia coli of a protective antigen of Erysipelothrix rhusiopathiae.

abstract：:Evidence showing that neutrophils play a protective role in the host response to infection by different intracellular parasites has been published in the past few years. We assessed this issue with regard to the infection of mice with Mycobacterium tuberculosis. We found a chronic recruitment of neutrophils to the inf...
