METHOD OF DIAGNOSTICS OF CANDIDIASIS OF UPPER RESPIRATORY TRACT IN WORKERS OF AGROINDUSTRIAL COMPLEX

FIELD: biotechnology.SUBSTANCE: method provides sampling of the material under study. Inoculation of the material under study on nutrient medium sabouraud followed by incubation on this medium at 37°C for 24 hours. A quantitative assessment of growth of yeast-like fungi of the genus Candida, and with a value exceeding 10*1 CFU/swab the candidiasis of upper respiratory tract is diagnosed. The obtained colonies are examined under the microscope and the isolated colonies of yeast-like fungi of the genus Candida are separated from these colonies. The isolated colonies of yeast-like fungi of the genus Candida are suspended in five test tubes containing liquid medium sabouraud with the phenol red indicator, where the discs with carbohydrates are added, and in the first test tube - a disc containing maltose, in the second - sucrose, the third - lactose, the fourth-galactose, the fifth - trehalose, and are incubated at 37°C for 24 hours, followed by assessment of colour change of the indicator. The colour change of the indicator to yellow is taken as one, lack of colour change is taken as zero, the sum of the values obtained in assessment of the indicator colour in five test tubes is calculated. If the value of the sum is 0 the candidiasis of upper respiratory tract caused by Candida kruzei is diagnosed, if it is 1 - the candidiasis of the upper respiratory tract caused by Candida glabrata is diagnosed, if it is 3 - the candidiasis of the upper respiratory tract caused by Candida albicans is diagnosed, if it is 4 - the candidiasis of the upper respiratory tract caused by Candida tropicalis is diagnosed, if it is 5 - the rest.EFFECT: invention enables to identify several types of yeast-like fungi of the genus Candida, causing candidiasis, and enables to take into account the quantitative growth of yeast-like fungi of the genus Candida, according to which the presence of candidiasis is judged.6 ex Изобретение относится к микробиологии и может быть использовано для диагностики кандидоза верхних дыхательных путей у работников агропромышленного комплекса. Способ предусматривает отбор исследуемого материала. Посев исследуемого материала на питательную среду Сабуро с последующей инкубацией на этой среде при 37°С в течение 24 часов. Проведение количественной оценки роста дрожжеподобных грибов рода Candida, и при значении превышающем 10*1 КОЕ/тампон диагностируют кандидоз верхних дыхательных путей. Полученные колонии микроскопируют и из этих колоний выделяют изолированные
