We also review the characteristics of Erwinia species and infections Erwinia is a genus of Enterobacterales bacteria containing mostly plant pathogenic species which was named for the famous plant pathologist, Erwin Frink Smith. It contains Gram-negative bacteria related to Escherichia coli, Shigella, Salmonella, and Yersinia. They are primarily rod-shaped bacteria. Many infect woody plants In some cases, health care professionals may use the trade names elspar or kidrolase or other names l-asparaginase or erwinia l-asparaginase when referring to the generic drug name asparaginase. Drug type: Erwinia L-asparaginase is an anti-cancer (antineoplastic or cytotoxic) chemotherapy drug. This medication is classified as an enzyme

Erwinia bacteria also readily colonize and infect damaged roots. Improper fertilization and high salt levels can cause initial damage to roots, which bacteria may exploit. Free draining soil or media is vital to ensuring water and nutrients flow through the root zone, and total soluble salts should be monitored What caused the necrotic tissue can be any one of several factors, but in the final analysis it's usually bacterial necrosis (Erwinia cacticida, literally Erwin's cactus killer) that is causing the damage, which left untreated can lead to the death of the cactus Females of reproductive potential should use effective contraception during therapy and for 3 months after the last dose of asparaginase (Erwinia); use of oral contraceptives is not recommended. Pregnancy Considerations. Based on data from animal reproduction studies, in utero exposure to asparaginase (Erwinia) may cause fetal harm. Patient. Erwinia carotovora is also known as Pectobacterium carotovia. Erwinia soft rot in cactus plants is caused by bacteria entering wounds or natural openings of the plant. Wounds can be from insect damage, pet damage, accidentally knocking the plant with gardening tools, etc Erwinaze (asparaginase Erwinia chrysanthemi) is indicated for the treatment of acute lymphoblastic leukemia (ALL) patients who have developed an allergy (hypersensitivity) to E. coli derived asparaginase and pegaspargase chemotherapy drugs used to treat ALL.

The bacterial rot disease is caused by Erwinia ananas, which is a facultative anaerobic bacterium Erwinia leaf spot, blight, stem rot, and soft rot Symptoms - The most common bacterial pathogens of these four foliage plants are Erwinia ca rotovora subsp. carotovo ra and subspecies of E. chrysanthemi. Both organisms cause soft rots or leaf spots and blight. The first symptom is usually soft, mushy Fireblight is a destructive, highly infectious and widespread disease caused by the bacterium Erwinia amylovora. Fireblight can be a problem in Georgia and is particularly prevalent in some counties. Fire blight attacks blossoms, leaves, shoots, branches, fruits, and roots Bacterial stalk rot of corn Bacterial stalk rot is caused by Erwinia dissolvens. It causes decay of the first internode above the soil. The rind and the pith become soft, brown, and water-soaked Erwinia induce the expression of efflux pump genes in response to plant-derived antimicrobials. The capability of Erwinia to co-opt plant defense signaling molecules such as salicylic acid to trigger multidrug efflux pumps might have developed to ensure bacterial survival in susceptible host plants

Fire blight is a destructive disease caused by a bacterium (Erwinia amylovora) that thrives in the warm, humid, and rainy weather that coincides with the start of the growing season, and it is easily spread.You can identify fire blight by several characteristics: Cankers on a tree's bark that look like discolored or wet patches, often with areas of dead or decayed sapwood around their edge Fire blight (caused by bacterium Erwinia amylovora) (Fig 3.) causes a dieback that can become a canker when it moves down a small branch to infect a larger branch. As the tissue on the larger branch dies and dries out it becomes cracked and sunken This attack is known by different names like Erwinia attack, Head rot, Soft rot, Snap off and Tip Over. Tissue culture raised Banana plants are prone to this bacterial attack. This disease is caused by soil borne bacteria Erwinia carotovora that enters the young banana plants through wounds that may be sustained at roots at the time of planting Bacterial soft rot disease is an infection that can devastate a crop of fleshy vegetables such as carrots, onions, tomatoes, and cucumbers, though it is most widely known for its attacks on potatoes.Soft rot disease is most easily recognized in these vegetables by soft, wet, cream to tan colored flesh surrounded by a dark brown to black ring Erwinia. Erwinia is a bacterial disease that can cause damage in a range of crops. It often produces watery looking, rotten patches on the leaves, fruit, flower or stalk. The bacterium is quite common and can develop rapidly in the greenhouse, spreading from plant to plant through crop handling and splash dispersal

Over seven Erwinia species and sub-species have been reported to occur in Hawaii (Raabe, et al., 1981). The following is a list of the reported pathogens from this genus (Erwinia) and the hosts they infect. The list is organized by the scientific name of the pathogen species (CAPITAL LETTERS), followed by the various susceptible plant hosts The disease is caused by an Erwinia bacterium, which causes a soft-rot symptom in the saguaro. It also been found in rotting cholla, prickly-pear, barrel and organ-pipe cacti. It has been isolated from naturally infected plants from Texas and Mexico, as well as Arizona
