RESUMO
Monoclonal antibodies against Ureaplasma urealyticum serotype 4 were produced by immunizing BALB/c mice with whole-cell antigens of the U. urealyticum serotype 4 reference strain. Ten monoclonal antibodies differentiated into two groups were found: one group included five monoclonal antibodies recognizing a band in immunoblotting that had a molecular mass of 81 kDa, and a second group included another five monoclonal antibodies recognizing three bands in immunoblotting that had molecular masses of 81, 75, and 71 kDa. Fifteen clinical U. urealyticum isolates were selected for serotyping with serotype 4-specific monoclonal antibodies and polyclonal antisera 1 to 14. The results obtained with polyclonal and monoclonal antibodies suggest the existence of heterogeneity of the serotype antigens among clinical isolates of U. urealyticum serotype 4.
