Abstract: A probiotic microcapsule for the treatment of reproductive tract infection and a preparation method and application thereof are provided. The probiotic microcapsule is obtained by coating probiotics with the coating material. The probiotics include one or several of Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus fermentum, Lactobacillus reuteri, Lactobacillus crimpus, Lactobacillus brevis, Lactobacillus salivary, Lactobacillus plantarum, Lactobacillus acidophilus, and Lactobacillus bulgaricus. As probiotics screened in reproductive tract, it has high safety; It endows probiotics with adhesion function to ensure their effect in the reproductive tract; It overcomes the defects of current antibiotic therapy; It is expected to be used in a variety of reproductive tract infectious diseases.

Abstract: A transdermal double-layer microneedle based on hydrogen producing probiotics and its preparation method and application thereof are provided. The transdermal double-layer microneedle consists of a needle body and a backing layer. The raw material of the needle body includes hyaluronic acid and hyaluronidase. The raw material of the backing layer includes methacrylate anhydride gelatin and silk fibroin protein. The hydrogen producing bacteria are loaded in the microneedles, and the pore size of the matrix material is lower than the diameter of the probiotics, which will not lead to the leakage of bacteria and has high safety. Treatment of inflammatory skin diseases by gas has low side effects. The needle tip is loaded with hyaluronidase to increase the tissue space and improve the effect of gas treatment. It is expected to be used in psoriasis and other inflammatory skin diseases.

Abstract: The present disclosure relates to a primer and a kit for rapid detection of bacteria and an application thereof, belonging to the technical field of bacterial detection. The present disclosure provides a primer for rapid detection of bacteria, a nucleotide sequence of a forward primer for the detection is shown in SEQ ID NO.1, and a nucleotide sequence of a reverse primer is shown in SEQ ID NO.2; a degenerate base W=A/T in the forward primer, and a degenerate base R=A/G in the reverse primer. The primer of the present disclosure may achieve rapid, wide, high-sensitivity and quantitative detection of bacteria, can be applied in the field of bacterial detection, and is more suitable for the clinical research and application of cells and stem cell-based products.
