【Objective】The objective of this study was to investigate the species and geographical distribution of pathogens in cow endometritis in various regions of China and to provide data support for screening out the best therapeutic drugs to reduce endometritis and economic losses to livestock husbandry.【Method】Cows with endometritis in different sizes of dairy farms were selected from Chifeng area,Zhangjiakou area,Weifang area,Chongqing area,Baoji area and Beijing area respectively.Uterine contents of 60 affected cattle were collected by sampler.The pathogenic bacteria isolated and purified from cow endometritis were identified by Gram stain and biochemical identification,and the distribution characteristics of pathogenic bacteria were analyzed.【Result】Weifang,Chifeng and Beijing area caused single infection in dairy cow endometritis.Baoji,Zhangjiakou,Chongqing area caused by cows endometritis with mixed infection.Chifeng,Chongqing,Zhangjiakou,Weifang,Baoji,Beijing caused by cow endometritis pathogens to Gram-positive bacteria.Chifeng region cow endometritis is the main pathogen Staphylococcus aureus.The main pathogen of cow endometritis is Streptococcus in southwest region,Escherichia coli in Zhangjiakou area,Streptococcus in Weifang area,,Staphylococcus aureus in Baoji region,Bacillus cereus in Beijing area,respectively.
