Abstract

Mycoplasma organisms were isolated for the frst time from naturally infected Nile carp (L. niloticus) in Egypt. The isolated organisms were investigated microbiologically, where they showed the typical characters of the genus Mycoplasma. The serological typing of the isolated organisms from L. niloticus revealed an antigenical difference from mycoplasma of farm animals and poultry. The experimental inoculation of healthy L. niloticus through gil scrafication resulted in mild gill damage with signs of asphyxia and low mortality. The In-Vitro antibiotic sensitivity testing for the isolated mycoplasma revealed their high sensitivity to Enroflocin and low sensitivity to Colistin sulphate.
