				Abstract 
 
              Aim: 
              Cystic 
              echinococcosis (CE) represents a serious parasitic disease at both 
              animal and public health levels. The majority of reports negated 
              the CE infection in buffaloes from Egypt; however, one study 
              illustrated their infection with G6 genotype (camel strain). The 
              present work contributed to update the epidemiological and 
              molecular knowledge about CE infecting this economically important 
              animal for better understanding of its role in maintaining the 
              Echinococcus life cycle.  
              Materials and 
              Methods: 
              A total of 120 
              slaughtered water buffaloes at Mansoura abattoir, Dakahlia 
              province, Egypt, were inspected for the existence of hydatid 
              cysts. Cysts location and fertility were examined. Five out of 27 
              revealed cysts were tested molecularly using both cytochrome C 
              oxidase subunit 1 and nicotinamide adenine dinucleotide hydrogen 
              subunit 1 (nadh1) genes.  
              Results: 
              Low prevalence 
              (4.2%) as well as considerably low fertility rate (14.8%) of 
              buffaloes CE was noted. G1 genotype (common sheep strain) was 
              revealed from the five examined cysts. At the level of nadh1 
              partial sequences, a globally singleton G1 haplotype was reported.
               
              Conclusion:
              This 
              the first report about the G1 infection in buffaloes from Egypt. 
              This study proposed the minimized role of this animal in 
              echinococcosis transmission. These findings could provide 
              preliminary data for the local control of this disease.
