The main objective of laboratory diagnosis of a diphtheria is identification of the causative agent by means of the minimum quantity of diagnostic tests for obtaining the authentic answer in the most short time. One of the major stages is capture and delivery of pathological material on which the efficiency of carrying out and timeliness of issue of the final answer depends. Considering emergence in the market of commercial liquid transport mediums, assessment of their efficiency for diagnosis of diphtheria is advisable. In the real work the pilot studies allowing to predict efficiency of use of the commercial transport liquid medium £-Transwab® with the liquid medium of Ames in two systems - with the standard applicator (system 1) and with the thin extended tampon for sampling from narrow cavities - urethral and nazofarengialny are conducted (system 2). In a research used a control toxigenic strain of Corynebacterium diphtheriae of a biovar of gravis No. 665. In an experiment "imitated" operating conditions of the medical organizations for storage of tampons with pathological material on diphtheria before their transportation in laboratory - on a table at the room temperature (6 and 20 hours), in the refrigerator (6 and 20 hours), in the thermostat (6 and 20 hours). After an incubation all tampons sowed the environment for primary crops ofpathological material on a blood tellurite agar.. Accounting of results was carried out in 24 and 48 hours of growth. It is established that the commercial transport liquid medium ofAmes can be usedfor capture of pathological material on diphtheria in the second half of the working day at storage in the conditions of the refrigerator. At the same time, it is necessary to consider a tampon form as the best results on a identification of the causative agent of diphtheria have been received when using a universal tampon.
