2005
Mutee-us-Salam, M.
Hundred faecal samples were examined by Direct Smear. Zinc-sulfate flotation and Sedimentation techniques. Prevalence was 2, 4 and 5 percent respectively. Although they are very cheap and simple techniques but detection of the disease in early stages is not possible. Whereas Agar Gel Precipitation Technique gave positive results as 8% is laborious technique. But the diagnosis during the early stages is possible. In Adult (above 2 years) the Prevalence was found 2.85% by Direct Smear Method. 4.28% by Zinc sulfate Flotation Technique. 4.28% by Sedimentation Technique and 8.57% by using Agar Gel Precipitation Technique. In Males the Prevalence was found 0% by Direct Smear Method. 0% by Zinc sulfate Flotation Technique. 6.26% by Sedimentation Technique and 6.26% by using Agar Gel Precipitation Technique. In Females the Prevalence was found 2.38% by Direct Smear Method. 4.76% by Zinc sulfate Flotation Technique. 4.76% by Sedimentation Technique and 8.33% by using Agar Gel Precipitation Technique. In Nili Ravi the Prevalence was found 2.35% by Direct Smear Method. 4.76% by Zinc sulfate Flotation Technique. 4.76% by Sedimentation Technique and 8.23% by using Agar Gel Precipitation Technique. In Kundi the Prevalence was found 0% by Direct Smear Method. 0% by Zinc sulfate Flotation Technique. 6.66% by Sedimentation Technique and 6.66% by using Agar Gel Precipitation Technique. From the results it appears that AGPT. Sedimentation technique, Zinc-sulfate flotation and Direct Smear Method can be ranked as No. 1, 2, 3 and 4 respectively in terms of their efficacy. Total economic losses due to fasciolois during three months (Oct.-Dec. 2004) were very high i.e. Rs.1016400.
