| Summary: | <b>Aim: </b>This study was performed to re-evaluate the efficacy of the combination
oxfendazole+oxyclozanide, after thirty years of its introduction into the Turkish
antiparasitic drug market.<p>
<b>Materials and Methods: </b>In this study, 32 sheep infected with gastrointestinal
nematodes were used. Sheep were selected on the basis of the number of eggs
in one gram of their fecal sample. Sheep selected were divided into two groups:
group I, sheep were treated orally at day zero, with oxfendazole+oxyclozanide
combination at a dose rate of 7.5 mg/kg and 15 mg/kg of body weight, respectively;
group II, sheep were used as untreated controls. Fecal samples were
collected from each sheep on day 1 of their treatment, and on days 7, 14, and
21 of post-treatment. To determine the anthelmintic drug treatment?s efficacy,
individual sheep?s fecal egg count per gram of feces was determined by performing
McMaster method and fecal egg count reduction test.<p>
<b>Results:</b> Fecal egg counts of these two groups were statistically not different
on the day of treatment. At day 7 of post-treatment, few eggs were detected
only in one sheep, and the mean of fecal egg counts of the treatment group was
66.7 ±66.7. On days 14 and 21 of post-treatment, fecal egg counts decreased
to zero in the treatment group but significantly did not change in the control
group. The efficacy of the combination was found to be 100% at day 14 and 21
of post-treatment.<p>
<b>Conclusion:</b> This study revealed that the combination
oxfendazole+oxyclozanide was highly effective against the gastrointestinal
nematodes in sheep. |
