  • A research study was undertaken to quantify fascioliasis in both live and slaughtered zebu cattle at Savar, Bangladesh. Eggs of Fasciola gigantica per gram of feces (EPG) was determined in a total of 213 fasciola infested live cattle. The EPG per animal ranged from 100 to 400 (mean $138.03{\pm}4.27SE$). Counting of F. gigantica was made in a total of 63 fasciola infested livers of slaughtered cattle. Number of immature flukes per liver ranged from 0 to 37 (mean $8.74{\pm}0.85SE$) and mature flukes ranged from 2 to 121 (mean $20.54{\pm}2.23SE$). Total load of flukes recovered per liver varied from 4 to 132 (mean $29.28{\pm}2.42SE$). Significantly higher EPG (p < 0.05) and higher load of flukes in the livers (p < 0.01) were observed from September to December (post monsoon and winter). The EPG and fluke counts were found significantly higher (p < 0.01) in animals after one year of age and these were also higher in female animals (p < 0.05) than the males.

  • Hematological value were determined from 140 Fasciola gigantica infested and 138 non-infested apparently healthy (control) zebu cattle from eight different sites of Bangladesh. The F. gigantica infested cattle have experienced of normocytic normochromic anemia indicated by the significant (p<0.01) decline of total erythrocyte count, hemoglobin level, packed cell volume and mean corpuscular hemoglobin concentration and significant (p<0.01) increase of erythrocyte sedimentation rate, as compared with non-infested control animals. Values of mean corpuscular volume and mean corpuscular hemoglobin content were not differed significantly between the infested and control animals. There observed significantly (p<0.01) higher eosinophil and neutrophil counts and significantly (p<0.01) lower lymphocyte counts in fasciola infested cattle in comparison with the control animals.

  • Male and female Sprague-Dawley rats 8 weeks of age were inoculated per os with 10 Fasciola hepatica metacercariae each. After the infection was verified by fecal examination, they were divided into four groups at 14 weeks post-inoculation; three groups were dosed orally at 10, 20 and 30mg/kg of closantel($Flukiver^{TM}$), a salicylanilide compound and the rest used as untreated control. Efficacy of closantel was monitored weekly by fecal examination of all infected animals starting during the second week post-treatment(PT) and continuing for three weeks. Closantel elicited 96.0, 86.9 and 87.4% efficacy in rats treated with 10mg/kg at the second, third and fourth week PT, respectively. It elicited a 100% efficacy in rats treated with 20 and 30mg/kg.

  • Although schistosomicidal drugs and other control measures exist, the advent of an efficacious vaccine remains the most potentially powerful means for controlling this disease. In this study, native fatty acid binding protein (FABP) from $Fasciola$ $gigantica$ was purified from the adult worm's crude extract by saturation with ammonium sulphate followed by separation on DEAE-Sephadex A-50 anion exchange chromatography and gel filtration using Sephacryl HR-100, respectively. CD1 mice were immunized with the purified, native $F.$ $gigantica$ FABP in Freund's adjuvant and challenged subcutaneously with 120 $Schistosoma$ $mansoni$ cercariae. Immunization of CD1 mice with $F.$ $gigantica$ FABP has induced heterologous protection against $S.$ $mansoni$, evidenced by the significant reduction in mean worm burden (72.3%), liver and intestinal egg counts (81.3% and 80.8%, respectively), and hepatic granuloma counts (42%). Also, it elicited mixed $IgG_1/IgG_{2b}$ immune responses with predominant $IgG_1$ isotype, suggesting that native $F.$ $gigantica$ FABP is mediated by a mixed Th1/Th2 response. However, it failed to induce any significant differences in the oogram pattern or in the mean granuloma diameter. This indicated that native $F.$ $gigantica$ FABP could be a promising vaccine candidate against $S.$ $mansoni$ infection.

  • Fecal samples were taken from 402 cows in Posung, Chonnam where was designated as a place for Korean native cattle breeding. Prevalence of internal parasitisms were determined by the fecal examinations using the floatation and sedimentation procedures. 62.9% of the cows were found as positive cases with excretion of the eggs of Fasciola hepatica in the fecal specimens. Of those infected with F hepatica 97 cows free of other pathogenic intestinal parasites were chosen for albendazole treatment. Albendazole tablets(10mg/kg) were administered to the cows twice at the interval of 4 weeks. Blood samples were collected via jugular vein prior to the first treatment, four weeks after the first treatment and four weeks after the second treatment, respectively. At the same time fecal samples were collected for parasitological examinations by sedimentation methods. The mean pretreatment count was 44 fluke eggs per gram of feces, which compared with 27 epg and 17 epg four weeks after the first and second treatment, respectively. Most of the hematological and biochemical values fluctuated within the normal ranges during the experiment. Eosinophil counts were high initially, decreased after the first treatment and thereafter remained steady. The opposite was the case with aspartate and alanine aminotransferases.
