Abstract: | Tetrads-forming mutant MT cells of Micrococcus luteus, both treated with chemical reagents and non-treated, were observed with a scanning electron microscope (SEM). The agglutinability of the cells with antiserum containing anti-teichuronic acid antibody was examined. The binding of protein A-gold particles to the cells, mediated with the antiserum, was also observed with SEM. A tetrad surface, not surface of each of four "unit monococci" constituting a tetrad, consisted of two or three smooth areas with borders. The difference in the surface features between M. luteus wild-type IFO 3333 (Monodane et al, Microbiol. Immunol. 33: 165-174, 1989) and the mutant MT cells is discussed. |
