The invention belongs to the field of microorganisms, and relates to lactobacillus rhamnosus and application thereof. The lactobacillus rhamnosus KC3 is separated from Xinjiang healthy bactrian camel milk, and the lactobacillus rhamnosus KC3 has the activity of inhibiting various pathogenic bacteria such as escherichia coli, klebsiella pneumoniae, salmonella, proteus mirabilis, staphylococcus aureus, staphylococcus epidermidis, listeria monocytogenes and streptococcus agalactiae. The metabiotics of the strain can enhance the sensitivity of pathogenic bacteria such as escherichia coli and staphylococcus aureus to antibiotics such as beta-lactam antibiotics, and can synergistically enhance the antibacterial effect of the beta-lactam antibiotics to the pathogenic bacteria such as escherichia coli, staphylococcus aureus, CRE or MRSA. The lactobacillus rhamnosus KC3 metagen can also destroy cell walls of pathogenic bacteria such as escherichia coli, staphylococcus epidermidis, CRE or MRSA and the like, and the formation of bacterial biofilms is inhibited.

The invention relates to the technical field of analysis and detection, in particular to an immunochromatography test strip for detecting shiga toxin-producing escherichia coli O103. Based on the characteristics of the quantum dots and the fluorescent microspheres, a probe is synthesized by utilizing the purified protein expressed by the pET-28a-O103 strain and the fluorescent microspheres, and the immunochromatography rapid detection test strip for identifying the shiga toxin-producing escherichia coli O103, which is simple to operate, is established, can be used for rapidly identifying the shiga toxin-producing escherichia coli O103 clinically, and can be used for rapidly detecting the shiga toxin-producing escherichia coli O103. The method has important significance on prevention and control of Escherichia coli diseases.
