This s this study examined a total of 750 faecal and 212 gallrnbladder samples for helminthes parasites in Abraka.rnSedimentation technique and Formalin Ethyl Acetaternconcentration were used to detect the presence of helminthrneggs in the samples. Analysis of variation (ANOVA) was usedrnto establish the relationship between the results obtained. Arntotal of 213(56.8%) were positive for cattle while 197(52.5%)rnsamples were positive for goat. Rainy season recorded higherrnlevel of helminth parasites prevalence of 135(63.4%) andrn109(55.3%) for cattle and goats respectively. From the onernhundred and eighteen (118) gall bladder samples collected fromrncattle, 87(73.7%) were positive to helminth parasites. Also, fromrnthe ninety four (94) gall bladder samples obtained from goat,rn63(67.0%) had at least a helminth infection in the gall bladder.rnThere was significant difference in the prevalence of helminthrnparasites for goat and cattle samples. Histological sections ofrnliver samples were cut at a thickness of 4.0µm, stained byrnhematoxylin-eosin and analyzed using conventional lightrnmicroscopy. Macroscopical examination showed that there isrncentrilobular hepatocellular necrosis and inflammation in thernliver lesion. Also, the liver showed a random hepatocellularrndegeneration. Based on the results, constant and regular dewarming should be carried out by herd owners and farmers torncontrol the rate of prevalence of helminth parasites in theserneconomically important animals.
