The morphological characteristics, pathogenicity and biological characteristics of the pathogen isolated from Maryland tobacco in Wufeng County of Hubei Province were studied in the laboratory. After cultivation on LB medium at 28℃ for48 h, the colonies were light yellow, circular or amorphous, translucent, with smooth and slightly concaved surface and neat edge. Observation under electron microscope showed that the isolates was red-shaped, decapsulated and gram-nega- tive in the size of (0.5 - 1.0) μm × (2.2 -3.0) μm, with 2 -8 flagella. After cultivation on CVP medium at 28 ℃ for 48 h, the colonies were sunken like a cup. The pathogen was able to grow in 5% NaCl medium at 37 ℃, and produced acid through glucose fermentation; it was facuhative anaerobic, and could use citrates, but could not produce indole. It was preliminarily confirmed that the pathogen causing Wufeng Maryland tobacco hollow stalk was Pectobacterium carotovorum subsp. carotovorum. 展开更多

Endophthalmitis is a serious ophthalmic disease characterized by changes in the eye's posterior segment,such as hypopyon and intraocular inflammation,vitritis being a hallmark.Infection-caused endophthalmitis can lead to irreversible vision loss,accompanied by eye pain or eye distention,and in the most severe cases the removal of the eyeball.Microorganisms such as bacteria,fungi,viruses,and parasites typically account for the disease and the entry pathways of the microbial can be divided into either endogenous or exogenous approaches,according to the origin of the etiological agents.Exogenous endophthalmitis can be derived from various occasions(such as postoperative complications or trauma)while endogenous endophthalmitis results from the bloodstream which carries pathogens to the eye.This review aims to summarize the application of new technology in pathogen identification of endophthalmitis so as to prevent the disease and better guide clinical diagnosis and treatment. 展开更多
