- Abstract
In order to know the differences of Cronobacter strains isolated from China and abroad, the information of strains with complete sequence type (ST) were download from PubMLST database, and their isolation source, species, ST and clonal complex (CC) were analyzed. Especially, food and clinical isolates at home and abroad were analyzed in depth. The results showed that isolates (907 strains) with complete ST in China were most, which were mainly derived from infant milk formula, spice and instant food. The isolates in China had high genetic diversities, and the strains of CC4 and CC7 type had a high proportion in strains (580 strains) isolated from food in China. However, there was no information about clinical isolates in China and other East and South Asian countries. The specific pathogenic information of isolated strains in China was quite different from that in European and American countries, only the strain ST256 (1 strain), ST60 (2 strains) and ST83 (2 strains) were associated with neonatal meningitis in China, while those in European and American countries mainly including ST4, ST1, ST12 and ST7, indicating that there may be differences in the phylogenetic evolution and virulence of Cronobacter strains between China and other countries, or it may be related to differences in the race of infected people.
