In order to reduce the risk of transmission of infectious diseases through transplantation of tissue allografts, one should examine tissues for the presence of microorganisms. However, there are no detailed tissue banking guidelines describing the culture method or incubation time to be used. Therefore, we compared two culture methods--blood agar plate versus Wilkins Chalgren broth--and three incubation times--2, 7 or 14 days for their performance. The ultimate aim is to use the optimal setting as standard operating procedure (SOP) for tissue allograft cultures. From 70 consecutive donors, 919 tissue samples were taken. All 919 tissue samples were incubated on blood agar as well as in Wilkins Chalgren broth for 7 days. 567 of these 919 tissue samples were left to incubate up to 14 days. Wilkins Chalgren broth yielded 24.5% (139/567) positive cultures after 14 days of incubation. This was slightly more than the growth on blood agar after 14 days (22.9%--130/567) (p=n.s.) and significantly more than the growth in Wilkins Chalgren broth after 7 days of incubation (21.9%--124/567) (p<0.05). Based on these results, Wilkins Chalgren broth has been implemented as the SOP. Since the yield of positive cultures increased from 2 to 7 days of incubation in broth (1.8 times) and the variability of species cultured from 7 to 14 days of incubation shifted towards mostly microorganisms known to be common contaminants, we established the cut-off at 7 days of incubation in Wilkins Chalgren broth.
