ERVINIYA

From Big Medical Encyclopedia

ERVYNIYa (Erwinia) — a genus of bacteria this. Enterobacteriaceae. Former names for groups of the bacteria united in a sort an erviniya — Bacterium typhi flavum, Enterobact-er agglomerans, Herbicola — Lathyri bacteria, Pectobacterium.

AA. along with representatives of other childbirth this. Enterobacteriaceae can be causative agents of intrahospital infections (see), hl. obr. at patients with immunological insufficiency. The intrahospital outbreaks of diseases as a result of parenteral administration of the solutions which appeared by the contaminated representatives of a sort an erviniya (E. herbicola) are described. The strains causing diseases in people quite often happen steady against a number of chemotherapeutic drugs.

Rod Erviniya includes 15 types (type-species — E. amylo vora) combined on the basis of their ecological communication with plants, in relation to the Crimea different types are pathogenic or saprofi-tichesky. AA. — the heterogeneous group of bacteria including subgroups standard representatives to-rykh are E. amylo vora (the causative agent of a burn — a necrotic disease of nek-ry fruit-trees), E. caro to vora (causes the soft decay of fabrics of plants connected with synthesis by bacteria pitch of lytic enzymes), E. herbicola (forms a yellow pigment and lives on a surface of leaves of healthy plants).

Bacteria of a sort E. represent odinochno the located gram-negative sticks of 0,5 in size — 1x1 — 3 microns, and a dispute do not form capsules, are mobile at the expense of peri-trikhialny flagellums, oksidazo-negative, katalazopolozhitel-ny, nek-ry types form a yellow pigment. They well grow on Wednesdays with peptone and beef tea. For growth of strains E. amylovora is necessary nicotinic to - that. Growth factors for nek-ry other types are not identified. Optimum temperature of growth 27 — 30 °. The maximum temperature of growth fluctuates from 32 ° to 40 ° for different types (strains). AA. utilize a number of carbohydrates with education to - you, do not form or form gas in insignificant quantity. Urease, lipases, proteases, Dnkaza are produced seldom. Splitting of pectin is specific to a number of types.
