The cellular reactions to defatted tubercle bacilli are complex and like those to heat-killed whole tubercle bacilli. The firmly bound lipid, when removed from these organisms, is non-acid-fast; it contains an hydroxy acid which is acid-fast and a polysaccharide, which is not. This hydroxy acid gives rise to foreign body giant cells and the tissues eventually become infiltrated with eosinophile...

Bartholomew, J. W. (University of Southern California, Los Angeles), and George Paik. Isolation and identification of obligate thermophilic sporeforming bacilli from ocean basin cores. J. Bacteriol. 92:635-638. 1966.-Obligate thermophilic sporeforming aerobic bacilli were isolated from 11 ocean basin cores taken from locations in a 150 mile long area off of the coast from Ensenada, Mexico, to S...

A description is given of a slide cell whereby the rate of migration of very small amounts of leucocytes can be followed and measured. The migration of polymorphonuclear leucocytes was found to be inhibited by virulent tubercle bacilli pathogenic for the class of animal (mammal or bird) from which the leucocytes were obtained; it was not affected by the avirulent variants of these microorganism...

We used a slide culture technique to detect tubercle bacilli surviving in sputum smears (n=46) after conventional heat fixation and Ziehl-Neelsen staining. In all heat-fixed sputum smears, tubercle bacilli survived after time 0 (n=22), 24 h (n=7), 48 h (n=7), 72 h (n=4), and seven days (n=6). None of the stained sputum smears showed growth on slide cultures. Viable tubercle bacilli remaining in...

gingivitis is an inflammatory destructive disease mainly caused by microbial plaques. gram-positive and gram-negative bacilli or cocci have been isolated from dental plaque and gingivitis. this study was going to isolate and characterize the pathogenic bacteria from gingival of 100 patients with oral gingivitis. enriched and specific media used for isolation of bacteria. identification of isola...
