The invention belongs to the technical application field of plant source antibacterial preparations, and particularly relates to a natural antibacterial agent based on folium artemisiae argyi vinegar extract as well as a preparation method and application of the natural antibacterial agent. The folium artemisiae argyi vinegar extract is a folium artemisiae argyi reflux extract, and an extraction solvent is rice vinegar. Compared with a folium artemisiae argyi extract extracted by pure water, 11 components of the folium artemisiae argyi extract extracted by rice vinegar are specific to the folium artemisiae argyi extract extracted by rice vinegar and comprise various metabolites such as flavonoids, phenols, alkaloids and sesquiterpenes, and the relative peak area of 39 components is larger than that of a water extract of folium artemisiae argyi. The folium artemisiae argyi vinegar extract has good antibacterial activity due to the specific components and more extracted components. The folium artemisiae argyi extract and the refined folium artemisiae argyi extract disclosed by the invention have an inhibiting effect on dermatophytes such as trichophyton rubrum, trichophyton mentagrophytes and microsporum gypsum, and the application range of a product taking folium artemisiae argyi as a raw material is expanded.

The present disclosure provides a topical spray composition comprising: (a) from about 0.05% to about 5% by weight of naftifine, or a pharmaceutically acceptable salt thereof, (b) a film former comprising an octyl acrylamide acrylate copolymer, and (c) an alcoholic solvent comprising at least one of an organic solvent, an organic solvent, and an organic solvent, a topical spray composition wherein the ratio of the alcoholic solvent to propellant in the composition is from about 1: 1 to about 3: 1 (w / w). The disclosure also provides a method of treating a dermatophyte skin infection or onychomycosis in a subject in need thereof, the method comprising topically administering to the subject a topical composition as described herein.

The present application belongs to the technical field of detection reagents, and particularly relates to a dermatophyte detection kit based on a recombinant LGBP-FITC fluorescent probe and application thereof. The present application obtains LGBP-Cys protein by performing C-terminal cysteine site-directed mutation on LGBP protein from Procambarus clarkii; then, the LGBP-Cys protein is directionally coupled with maleimide-activated FITC under mild neutral conditions, so that the problem of protein activity damage caused by traditional random coupling is solved; finally, the coupling product is placed in a composite stabilizing solution containing an anti-quenching agent, so that the stability of the probe and the detection signal-to-noise ratio are significantly improved. The kit is simple to operate, and detection can be completed within 15 minutes. The kit has high sensitivity, high specificity and visualization advantages for common clinical dermatophytes, and is suitable for rapid bedside diagnosis.

The present invention discloses a culture medium for dermatophytes, a preparation method and a method for culturing dermatophytes, and belongs to the field of biotechnology. The culture medium for dermatophytes comprises components including starch, peptone, chloramphenicol, agar, a soluble magnesium salt, a soluble cesium salt, cycloheximide and gentamicin. The preparation method of the culture medium for dermatophytes comprises: stirring and dissolving starch, peptone, agar, a soluble magnesium salt and a soluble cesium salt according to a concentration ratio, sterilizing the mixture, and then adding cycloheximide, gentamicin and chloramphenicol to obtain the culture medium. The present invention also proposes a culture medium for dermatophytes or a method for culturing dermatophytes using the culture medium for dermatophytes, comprising: inoculating dermatophytes into a culture medium and culturing at 28-30°C for more than 3 days; further, the dermatophytes are preferably Microsporum canis. The culture medium can accelerate the colony growth rate of dermatophytes.

The invention relates to a folium artemisiae argyi itching-relieving and bacterium-inhibiting ointment and a preparation method and application thereof.The folium artemisiae argyi itching-relieving and bacterium-inhibiting ointment is prepared from, by weight, 4-6 parts of medicinal material extract, 36-42 parts of a water phase, 33-38 parts of an oil phase and 16-22 parts of auxiliary materials; the auxiliary materials comprise soybean peptide powder, glycerol and borneol powder. A medicinal material extract is extracted from raw materials of folium artemisiae argyi, fructus cnidii and golden larch bark compounded with multiple traditional Chinese medicinal materials, and the folium artemisiae argyi itching-relieving and antibacterial ointment is obtained after the medicinal material extract is mixed with milk-white paste obtained after a water-phase and oil-phase saponification reaction, soybean peptide powder, glycerol and borneol powder and can be used for preparing a medicine for treating beriberi caused by dermatophytes. The soybean peptide powder and the glycerol in the folium artemisiae argyi itching-relieving and bacterium-inhibiting ointment are combined together for use and have a synergistic effect, so that the folium artemisiae argyi itching-relieving and bacterium-inhibiting ointment is resistant to high temperature, low temperature and centrifugation and is not liable to oxidize and discolor, antibacterial components are not liable to volatilize under the conditions of high temperature and low temperature, and a relatively good antibacterial effect is kept.

Provided are compositions and methods for detecting one or more dermatophyte organisms in a sample using capture antibodies.

The invention discloses a primer, a probe, an implementation method and a detection system for qPCR detection of SQLE drug-resistant mutation of dermatophytes, and the method comprises the following steps: identifying a plurality of key mutation sites related to drug resistance by comparing an obtained dermatophytes SQLE gene sequence with a reference sequence in an NCBI database; designing a specific primer, a TaqMan-MGB fluorescent probe and a wild type closed probe modified by the MGB probe based on the mutation site, and verifying the sensitivity and the specificity through the strain level; the method comprises the following steps: constructing a mixed DNA sample model containing drug-resistant strain DNA, wild type strain DNA and human DNA, optimizing a reaction system of single and multiple qPCR detection, and determining an optimal reaction system of qPCR detection. According to the specific primer and probe for qPCR detection of dermatophyte SQLE drug-resistant mutation with specificity meeting requirements and an optimized reaction system for qPCR detection, whether dermatophyte SQLE drug-resistant mutation exists or not can be quickly verified, the sensitivity and specificity of dermatophyte drug-resistant detection are improved, early precise treatment is facilitated, and prognosis of patients is improved.
