Abstract

 
Efficacy and pharmacokinetics of kanamycin were Studied in P. fluorescens infected Clarias lazera (Nile catfish). The clinical sings of P.fluorescens infection started after 12-24 hours post intraperitoneal inoculation. Kanamycin was injected in a single dose (20 mg/kg b.wt.) in the infected group and another apparently healthy control group. Recovery percent reached 73.33 in the infected fish group after 48 hours® post antibiotic injection Kanamycin was rapidly absorbed after intraperitoneal injection and reached its highest concentration 9.87+0.00059 and 9.20+0.85 µg/ml four hours post injection in normal and infected fish groups, respectively. Kanamycin was rapidly absorbed in infected fish ( a = 0.2726 + 0.002h"! and ty < & = 2.69 + 0.16 min.) than in normal fish a= 0.20420.009h"! and ty, a= 3.4420.14 min.). Kanamycin was rapidly excreted in infected fish with ty 5 B= 5.63+0.3764 hrs than in normal fish with tp 5 B= 7.55+1988 hrs. The interval between doses was short in infected fish 44.28 hrs than in normal fish 55.85hrs.
