The cytochrome oxidase (CO), aminopeptidase (AMP), succinic dehydrogenase (SD), acid phosphatase, esterase, and alkaline phosphatase of rabbit mononuclear (MN) and polymorphonuclear (PMN) peritoneal exudate cells and pulmonary alveolar macrophages (AM) - air dried on Mylar strips - were characterized by histochemical techniques with respect to stability,(More)
The purpose of these studies was to identify some of the extracellular proteolytic enzymes associated with the development and healing of acute inflammatory lesions. Lesions were produced in the skin of rabbits by the topical application of the military vesicant, sulfur mustard (SM). Full-thickness, 1-cm2 central biopsies of the lesions were organ-cultured(More)
The rabbit model of tuberculosis (TB) is important because rabbits develop a disease that is similar to TB in humans, namely, granulomas with caseous necrosis, liquefaction, and cavities. We describe here a comparison of inbred and outbred New Zealand White rabbits infected by aerosol with either Mycobacterium tuberculosis Erdman or H37Rv strain. Five weeks(More)
We sought to characterize the lung cellular immune responses to inhaled Mycobacterium tuberculosis (Mtb) of the susceptible inbred Thorbecke rabbit (the genomically sequenced strain, now unavailable) and compare it to outbred, Mtb-resistant, New Zealand White rabbits. Using Mtb CDC1551, we confirmed that the inbred rabbits allowed establishment of infection(More)
It is widely believed that cell-mediated immunity and the associated ability of macrophages to destroy or inhibit the bacillus are all that is required to control pulmonary tuberculosis. However, although cell-mediated immunity is a major host defense against the tubercle bacillus, it is fully effective only in one of the four stages of the disease. Here,(More)
