Abstract
Epidemiological studies were undertaken at slaughter houses, live stock farms, veterinary hospitals and on household buffaloes under different management and climatic conditions in four different districts of the Punjab province. Infection rate was 7.83%, 12.33%, 7.17% and 4.25% respectively in the cattle at the slaughter house, live stock farm, veterinary hospital and at household cattle. Overall the highest prevalence in terms of season, 26% and 14.50%, was recorded during autumn at live stock farms and slaughtered cattle followed by 9.75% veterinary hospitals during summer and the lowest (2.5%) in household cattle was recorded during winter. It was observed that a higher infection rate was recorded in younger cattle (below two years of age) than older (above two years of age). Male cattle were more commonly affected than females. Snails belonging to genera Bulinus, Lymnaea and Planorbis were observed which are responsible for the transmission of paramphistomosis.Provedena su epizootiološka istraživanja paramfistomoze u goveda na klaonicama, farmama, veterinarskim klinikama i manjim gospodarstvima pod različitim uvjetima držanja i klime na području Punjaba. Invadiranost je istražena u četiri različite skupine goveda. Na klaonicama je pronađeno 7,83% invadiranih goveda, dok je na farmama taj broj bio nešto veći i iznosio je 12,33%. Među govedima na klinikama svega 7,17% životinja bilo je invadirano. Najmanji broj invadiranih goveda (4,25%) dokazan je u manjim gospodarstvima. U jesenjim mjesecima zabilježena je najveća učestalost u goveda s farmi (26%) i klaonica (14,50%). U goveda s klinika ljeti je dokazana učestalost od 9,75%. Najmanji broj invadiranih goveda dokazan je zimi u malim obiteljskim gospodarstvima (2,5%). Treba naglasiti da je najveća invadiranost zabilježena u goveda mlađih od 2 godine. Mužjaci su bili češće invadirani od ženki. Terenskim istraživanjima na istom području dokazani su posrednici, puževi iz rodova Bulinus, Lymnaea i Planorbis
