428 MANUAL OF BACTERIOLOGY. 



CURLED, composed of parallel chains in wavy strands, as in anthrax 

 colonies. 



DIASTASIC ACTION, same as DI ASTATIC, conversion of starch into 

 water-soluble substances by diastase. 



ECHINTJLATE, in agar stroke a growth along line of inoculation, with 

 toothed or pointed margins; in stab cultures growth beset with 

 pointed outgrowths. 



EFFUSE, growth thin, veily, unusually spreading. 



ENTIRE, smooth, having a margin destitute of teeth or notches. 



EROSE, border irregularly toothed. 



FILAMENTOUS, growth composed of long, irregularly placed or inter- 

 woven filaments. 



FILIFORM, in stroke or stab cultures a uniform growth along line of 

 inoculation. 



FIMBRIATE, border fringed with slender processes, larger than fila- 

 ments. 



FLOCCOSE, growth composed of short curved chains, variouly oriented. 



FLOCCULENT, said of fluids which contain pseudozoogloeae, i. e., 

 small adherent masses of bacteria of various shapes and floating 

 in the culture fluid. 



FLUORESCENT, having one color by transmitted light and another by 

 reflected light. 



GRAM'S STAIN, a method of differential bleaching after gentian violet, 

 methyl violet, etc. The + mark is to be given only when the bacteria 

 are deep blue or remain blue after counterstaining with Bismark brown 



GRUMOSE, clotted. 



INFUNDIBULIFORM, form of a funnel or inverted cone. 



IRIDESCENT, like mother-of-pearl. The effect of very thin films.. 



LACERATE, having the margin cut into irregular segments as if torn. 



LOBATE, border deeply undulate producing lobes (see undulate). 



LONG, many weeks, or months. 



MAXIMUM TEMPERATURE, temperature above which growth does 

 not take place. 



MEDIUM, several weeks. 



MEMBRANOUS, growth thin, coherent, like a membrane. 



MINIMUM TEMPERATURE, temperature below which growth does 

 not take place. 



MYCELIOID, colonies having the radiately filamentous appearance of 



mold colonies. 

 NAPIFORM, liquefaction with the form of a turnip.
