Objective To analyze the bacteria intercepted in China entry plant quarantine in recent years, and to make sure the importance and the severity of bacteria invading China is facing now. This paper will provide a reference to forestry plant quarantine.
Method A statistical analysis was made on the bacteria intercepted in China entry plant quarantine during 2010-2015 from the aspects of quarantine processes, origin country (region), quarantine bacteria, and forestry related bacteria.
Result During the period of 2010 to 2015, China's entry ports intercepted a total of 7736 batches of bacteria, belonging to 139 species which came from 70 countries/regions. The main hosts for these bacteria intercepted were fruits and seeds. Among the bacteria intercepted, there was 521 batches of quarantine bacteria, belonging to 16 species (10 species of which could infect flowers and forest.), 835 batches of pathogenic bacteria of flowers and forest, belonging to 23 species, and 2016 batches of Enterobacteriaceae bacteria, belonging to 32 species. No Enterobacter cancerogenus, Erwinia amylovora or Erwinia pyrifoliae were found.
Conclusion During the period of 2010 to 2015, both the batches and species intercepted at entry ports showed an upward trend. The risk of quarantine bacteria invasion is becoming more serious.
