Description

(54) СПОСОБ БАКТЕРИОПСГИЧЕСКОГО КОНТРОЛЯ ПИТАТЕЛЬНЫХ СРЕД ДЛЯ ВЫДЕЛЕНИЯ ЧУМНОГО МИКРСБА(54) METHOD OF BACTERIOPSGIC MONITORING OF NUTRITIOUS MEDIA FOR ISOLATION OF THE PERSONAL MIKRSBA

питлтепьных сред те же, что и .при уста- новлении известного штамма. В случав отсутстви  роста колоний в контролируемую среду добавл ют аргинш1 в дозе ЗО-5О млг/л. Если возникает об установлении зависимости роста от 1федшественников биосинтеза аргинина, дл  этих целей выбирают другие тесткультуры перечисленных штаммов. Добавление в среду аргинина приводит к по влению роста всех аргинин-ч итруллин и орнитинзависимых штаммов, при посеве минимальных доз (из 1ОО микробных клеток вырастает 55-90 колоний).The nutrient media are the same as in the establishment of a known strain. In the case of the absence of growth of colonies, arginsh1 is added to the controlled medium at a dose of 30–30 ml of lg / l. If it arises about establishing the dependence of growth on 1 archequin biosynthesis deputies, other test cultures of these strains are selected for this purpose. The addition of arginine to the medium leads to the growth of all arginine-h itrulline and ornithine-dependent strains, when seeding minimal doses (55-90 colonies grow from 1OO microbial cells).

Преимущество предлагаемых тестштаммов перед вакцинным штаммом ЕВ заключаетс  в том, что последний рас1гет на средах, не содержащих аргинина и его предшественников.The advantage of the proposed test strains over the EB vaccine strain is that the latter is used on media not containing arginine and its precursors.

Штамм 67 l-lor ptw  вл етс  также высокочувствительным,к полимиксину и не растет при его концентрации в среде 12,5-25 мкг/мл среды, в то врем  как исходный штамм 671 вырастает при концентрации 1ООО мгк/ мл. Поэтому он может быть рекомендован дл  изучени  причин по влени  высокой чувствительности к полимиксину, а следовательно , и дл  изучени  характера строени  клеточной стенки возбудител  чумыStrain 67 l-lor ptw is also highly sensitive to polymyxin and does not grow when its concentration in the medium is 12.5-25 µg / ml of the medium, while the original strain 671 grows at a concentration of 1OOO μg / ml. Therefore, it can be recommended to study the causes of the high sensitivity to polymyxin, and consequently, to study the nature of the structure of the cell wall of the plague pathogen.

Штамм 671-69а - сС)иэ-за высокой чувствительности к хлорамфениколу и ауксотрофности может быть использован также дл  изучени  особенностей биосин теза РНК и белка чумным микробом, а контрольным штаммом при этом може служить штамм 671-6 Юг цбшнар ду со штаммом 671-7lci g cEm.Strain 671-69a - cC) and, due to its high sensitivity to chloramphenicol and auxotrophy, can also be used to study the features of RNA and protein biosynthesis by the plague microbe, and the control strain can be the 671-6 strain of the strain with strain 671-7lci g sm.

Штамм 671-71с1 -д се 1Гиз-за сравнительно стабильной и высокой вирулент-Strain 671-71s1-d ce 1Giz due to relatively stable and high virulence

ности, а также наличи  генетической метки (зависимости от цитруллина) может быть рекоме1здован дл  определени  характера напр женности иммунитета при чуме, что способствовало бы унификации метода , его определени  к подбору новых, более эффективных противочумных вакцин .Все перечисленные штаммы могут быть использованы дл  изучени  путей биосинтеза аргинина и св зи вирулентности с аргинином, цитруллином и орнитином у возбудител  чумы.as well as the presence of a genetic label (depending on citrulline) can be recommended to determine the nature of the intensity of immunity in the plague, which would contribute to the unification of the method, its definition for the selection of new, more effective anti-plague vaccines. All of these strains can be used to study ways arginine biosynthesis and the association of virulence with arginine, citrulline and ornithine in the plague pathogen.

Предлагаемый способ позвол ет повысить прочность бактериологического контрол  питательных сред дл  вьщелени  чумного микроба.The proposed method makes it possible to increase the strength of bacteriological monitoring of nutrient media for the plague microbe.
