Xiao-ying,ZHANG Chao-wu,PEI Xiao-fang,et al (West China School of Public Health,Sichuan University,Chengdu 610041 ,China)  
Objective: To study the vector-host syste m Methods :Gram stain and morphology,H 2O 2 enzyme,carbohydrates fermentation to produce acid,arginine amino acid dehydration and antibiotic resistance test phenotypes were performed Results: The characters of Lactococcus lactis subsp cremoris MG1363 ,Lactococcus lactis subsp lactis IL 1403,MG1363 which containing plamid pMG 36e a nd Lactobacillus acidophilus ATCC4356 is consistent with their phenotypes in Bergey' s manual of determinative bacteriology There is erythromycin resistance gene in plasmid pMG36e Conclusion: This Lactic acid bacteria host -vec tor system canbe selected by the erythromycin resistant character from the vecto r and can be utilized to study the clone and expressian of genes in the Lactic acid bacteria.
