摘　　要：[Objective]This paper aimed to determine the main pathogens causing dairy cattle recessive mastitis in eastern Hebei and provide certain reference for local veterinarians and cow farmers to prevent and cure the disease.[Method]512 cows from 5 different farms in eastern Hebei were selected,and LMT,milk ph test and somatic cell direct counting methods were combined and used to conduct recessive mastitis＇ s epidemiological investigation,as well as isolate and identify the pethogens.[Result]The results indicated that the incidence of recessive mastitis is 60.7%（311 / 512）,bacteria isolation rate reached 87.8%（273 /311）.Total 81 isolates,belonging to 3 classes and 5 types were identified in milk samples of positive milk area from 273 cows with recessive mastitis.Among which,19 isolates were Streptococcus,accounting for 23.45%.Staphylococcus had 31 isolates,accounting for 38.27%.Enterobacter had 3,accounting for 3.7%.Other unshaped had 28 isolates,accounting for 34.6%.[Conclusion] The main pathogens caused dairy cattle recessive mastitis in eastern Hebei were Streptococcus agalactiae and Staphylococcus aureus.[Objective]This paper aimed to determine the main pathogens causing dairy cattle recessive mastitis in eastern Hebei and provide certain reference for local veterinarians and cow farmers to prevent and cure the disease.[Method]512 cows from 5 different farms in eastern Hebei were selected,and LMT,milk ph test and somatic cell direct counting methods were combined and used to conduct recessive mastitis＇ s epidemiological investigation,as well as isolate and identify the pethogens.[Result]The results indicated that the incidence of recessive mastitis is 60.7%（311 / 512）,bacteria isolation rate reached 87.8%（273 /311）.Total 81 isolates,belonging to 3 classes and 5 types were identified in milk samples of positive milk area from 273 cows with recessive mastitis.Among which,19 isolates were Streptococcus,accounting for 23.45%.Staphylococcus had 31 isolates,accounting for 38.27%.Enterobacter had 3,accounting for 3.7%.Other unshaped had 28 isolates,accounting for 34.6%.[Conclusion] The main pathogens caused dairy cattle recessive mastitis in eastern Hebei were Streptococcus agalactiae and Staphylococcus aureus.
