Abstract: To understand the overall status and focus of bovine mastitis vaccine research,knowledge maps of mainly country,institution,author,cite journal,cite reference,keyword,year distribution of publications on research of bovine mastitis vaccine were studied by Citespace Ⅲ,which collected 4 205 international scientific literatures download from Web of Science^TM core collection (1995 to 2015).The results showed that in research field of bovine mastitis vaccine,the number of published papers increased from 1995 to 2012,but it began to decrease in 2013;Countries and institution involved in the research were mainly distributed in America,Europe and Asia,and universities played important roles in this field;In addition,the research field were mainly focus on:Isolation and identification of pathogens,detection of drug susceptibility and pathogenesis exploration;Immune response and relevant regulatory factor in infected dairy cows;Best period for prevention and treatment;Screening for candidate antigen.In future time,studies will pay more attention on research of NF-κB and biofilm in field of bovine mastitis vaccine.
