Four to six slides for every rat were deparaffinated with xylene and alcohol of different concentration, rinsed in tap water and then in distilled water, stained in 0.1% thionine solution for 10 minutes, rinsed quickly in distilled water, differentiated in 95% HCl-alcohol for 2-10 minutes, dehydrated in alcohol of different concentration for 5 minutes every time, cleared in xylene for 5 minutes, and mounted with neutral balsam solution.
Bacterial colonies grew on Brucella agar supplemented with 5% horse serum in the presence of basic thionine and safranine O; C[O.sub.2] was not required for growth, and [H.sub.2]S was not produced.
(17) They were identified to the species level via conventional methods (the requirement for C[O.sub.2] for growth, production of [H.sub.2]S, urease production, sensitivity to thionine and basic fuchsin, and agglutination with specific antiserum).
Since most microbial cells are electrochemically inactive, electron transfer from microbial cells to the electrode is facilitated by the help of mediators such as thionine, methyl viologen, humic acid, and so on [66].
