p.825-840. In the present study ten isolates of Ustonella anguil/ arum were isolated from Clarias gariepi·· /lU.\' exhibited ulcerative lesions. The prevalence of infection was 16.7 %. The organisms were identified phenotypically to be a variant strains of L. 1Illguil!arum and the biochemical deviation were found in Voges Proskauer test and fermenta-· tion of mannitol. Experimentally, the infected fish showed severe skin ulcerations and high mortality rate. Electrophoresis of serum proteins revealed a significant decrease in δ,β and α globulins on day 4 post infection (PI) and for β globulin only on day 8 PI. In addition, the total serum globulin was dropped significantly on day 4 PI and nonsignificantly on day 8 PI when compared with its value for control group. Moreover, the albumin / globulin ratio was significantly elevated in the infected groups than in control one. Includes references. Summary in Arabic.
