Methods: A total of 1000 cattle, Sistani breed (n= 450) and Brahman breed (n= 550) of all sex and age groups were inspected at random for the presence of paramphistomidae flukes in Zabol slaughterhouse from December 2012 to Octo-ber 2013. Results: Paramphistomes were found in 369 of 1000 necropsied cows (36.9%; 95% CI: 30.1-41.9%), with significant higher prevalence of infection in Brahman breed than in Sistani breed (51% vs 19.3%). No significant correlation between prevalence, intensity of infection, sex and age of cattle was noted. Despite the dif-ference in the seasonal variations of prevalence, and the relation between the inten-sity of infection and season, these were not statistically significant. The mean inten-sity of infection in Brahman breed was higher (652.66 ± 281.5) than Sistani breed (123.32 ± 32.2). The identification of stained trematodes to the species revealed 40, 20, 20, 15 and 5% Gastrothylax crumenifer, Cotylophoron cotylophorom, Paramphistomum cervi, Carmyerius spatiosus, Explanatum explanatum, respectively. Conclusion: The present results will contribute to our understanding of the epi-demiology of paramphistomumosis in southeastern Iran.     https://ijpa.tums.ac.ir/index.php/ijpa/article/view/324 https://ijpa.tums.ac.ir/index.php/ijpa/article/download/324/482
