ABSTRACT
The present paper is aimed to explore the origins of Proteus mirabilis (PM) whorl swarming growth phenomenon. The whorl swarming growth phenomenon of PM was observed by changed bacterial culture inoculation time, humidity, vaccination practices, cultured flat placement, magnetic field, pH and other factors. Bacterial ring spiral direction of rotation is counterclockwise and the volatile growth process of PM was whorl swarming growth phenomenon. Spiro fluctuation phenomenon was of high frequency in the sealing tanks by cultured anytime inoculation, wherever inoculation technique applied or not, the presence or absence of the magnetic field, and wherever the dish position was. The experimental results showed that the whorl swarming growth phenomenon of PM requires specific pH environment, in which the facts may be relative to its genetic characteristics and the Earths rotation.

OBJECTIVE:To study the resource distribution and characteristics of Fritillaria in order to ensure clinical medication safety.METHODS:Main stream commodities of Fritillaria were analyzed in respect of its germplasm origin,distribution and characteristics.RESULTS & CONCLUSIONS:Different category of Fritillaria was characterized by vertical distribution,and there were differences in characteristics among the different category of Fritillaria.Therefore,ecological adaptability should be considered in planting Fritillaria.
