Survival of genital mycoplasma on various bacteriological swabs and transport media. 1981

F Busolo, and T Baratto, and G Bertoloni, and A Grossato

An approach to diagnostic microbiology necessitates measures which maintain the flora unchanged during the transportation of the specimens to the laboratory, preserving the viability of labile and fastidious organisms such as mycoplasma. Some of these problems have been studied in the present investigation. Five different swabs (untreated, albu, charcoal, alginate and phosphate-buffered albumin) and three transport media (Stuart, Amies and MTB) were examined using genital mycoplasma. Absorbent effect of swabs treated with albumin is lower than all the others while the antimycoplasma activity, due to the toxic substances present in the fiber of tip swab, is always lower for the charcoal swab. Concerning transport media, the most favourable results were obtained with the MTB medium. In this medium M. hominis and U. urealyticum counts decreased about 0.5 log and M. fermentans decreased 1.25 log after seven days at 4 degrees C. Furthermore, after inoculation of mycoplasma, MTB can be frozen at -20 degrees C without greatly modifying the titer. The reasons of the different performance of transport media on mycoplasma survival were discussed.

UI	MeSH Term	Description	Entries
D009174	Mycoplasma	A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.

D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture
D000042	Absorption	The physical or physiological processes by which substances, tissue, cells, etc. take up or take in other substances or energy.
D000418	Albumins	Water-soluble proteins found in egg whites, blood, lymph, and other tissues and fluids. They coagulate upon heating.	Albumin
D000464	Alginates	Salts and esters of ALGINIC ACID that are used as HYDROGELS; DENTAL IMPRESSION MATERIALS, and as absorbent materials for surgical dressings (BANDAGES, HYDROCOLLOID). They are also used to manufacture MICROSPHERES and NANOPARTICLES for DIAGNOSTIC REAGENT KITS and DRUG DELIVERY SYSTEMS.
