Listonellosis in ciarias gariepinus : phenotypic and serological identification of ustoneuaanguilla.rum isolated from ulcerative lesions [electronic resource]. مرض الليستونيلوزيز فى أسماك الكلاريس جاريبينس: التصنيف الظاهرى والسيرولوجى لليستونيلا انجوليرم المعزوله من الأضرار المرضية التقرحية. - 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.
