Development of resistance to a drug (e.g., penicillin) by bacteria previously susceptible to its destructive effects. Drug or other chemical that kills bacteria. The ability of bacteria to survive and cause continuous infection in the presence of antibiotics.  

Glass tubes open at both ends, allowing the extrusion of an agar cylinder after due incubation, and the recovery of anaerobes therefrom.  

Method for lipid granules in bacteria: alcoholic Sudan Black B is applied, differentiated with xylol, and followed by a dilute carbol-fuchsin counterstain. The organisms stain lightly pink, the granules grey or blue-black.

Species infecting goats, sheep and man (especially along the Mediter-ranean littoral); the organism of classical undulant fever. Grows in both thionin and fuchsin.  

Diagnosis of leptospirosis by the agglutination of leptospires by patient serum. The test is similar to the agglutination-lysis test, but (1) leptospira suspensions are killed by formalin; and (2) test preparations are not incubated, but stored at 4°C overnight before reading.  

Medium for the cultivation of anaerobic organisms, in which the reduced state existing at the time of sterilization is maintained by sodium thioglycollate. The medium is a meat extract glucose broth incorporating watery agar, with methylene blue as an indicator of oxidation.
