Description

Современные методы серологического анализа бактерий, учитывающие суммарный эффект реакции антиген-антитело на большом числе клеток, не пригодны дл  регистрации этой реакции на отдельных клетках , что необходимо при изучении см ешанных культур, изменчивости бактерий и дл  идентификации возбудителей в патологическом материале .Modern methods of bacteriological serological analysis, taking into account the total effect of the antigen-antibody reaction on a large number of cells, are not suitable for recording this reaction on individual cells, which is necessary when studying cmh cultures, the variability of bacteria and for identifying pathogens in the pathological material.

Предлагаемые;, способ позвол ет проводить серологический анализ отдельных бактериальных клеток. Сущность изобретени  заключаетс  в том, что примен етс  аноптральна  микроскопи  бактериальных клеток , обработанных гомологичной антисывороткой и нммергированных в желатиновом геле с показателем светопреломлени , равным соответствующему показателю протопласта клетки. Каплю исследуемоГ взвеем (жидкой культуры или смыва бактериальной массы с поверхности плотной питательной среды) нанос т на покровное стекло и смешивают с каплей соответствующей антисыворотки. Сразу же после смешивани  покровное стекло (каплей книзу) накладывают на предметное стекло, предварительно покрытое тонким слоем (не более 0,2 лш) желатинового гел  с соответствующим показателем светопреломлени . Приготоьленный препарат исследуют в аноптральном микроскопе. При этом. в случае положительной реакции антиген-антитело, клетки имеют вид оптически пустых тел, окаймленных утолн1енпой и блест п1,ей клеточной стенкой.The proposed; method allows for the serological analysis of individual bacterial cells. The essence of the invention is the use of anoptral microscopy of bacterial cells treated with homologous antiserum and immersed in a gelatin gel with a refractive index equal to that of the cell's protoplast. A drop of the test sample (liquid culture or washout of the bacterial mass from the surface of a dense nutrient medium) is applied onto a cover glass and mixed with a drop of the corresponding antiserum. Immediately after mixing, the cover glass (drop down) is applied to a glass slide, previously coated with a thin layer (no more than 0.2 lsh) of gelatinous gel with a corresponding refractive index. The prepared preparation is examined in an anoptric microscope. Wherein. in the case of a positive antigen-antibody reaction, the cells have the form of optically empty bodies, bordered with luster and glitter p1, with its cell wall.

Дл  приготовлени  желатинового гел  навеска сухой очищенной желатины добавл етс  к определенному объему слабощелочного 0,1 М раствора NaCl и оставл етс  на несколько часов до полного набухани  желатины. Затем осторожным подогреванием желатину раствор ют и просветл ют путем кип чени  с  ичным белком и удалени  хлопьев фильтрацией или центрифугированием расплавлен1 ой массы. ПослеTo prepare a gelatin gel, a portion of the dry, purified gelatin is added to a specific volume of weakly alkaline 0.1 M NaCl solution and left for several hours until the gelatin is completely swollen. Then, gently heating the gelatin is dissolved and clarified by boiling with the egg protein and removing the flakes by filtration or centrifugation to melt the mass. After

Показатель светопреломлени  находитс  в следуюи1ем соотношении с концентрацией желатины (в %):establishing a neutral reaction, the molten gelatin is poured into test tubes and sterilized by fractionally flowing steam. The refractive index is in the following ratio with the concentration of gelatin (in%):
