Overview of Research Progress and Current Utilization of Propolis
Propolis is a resinous substance collected by honeybees from tree buds, bark and other parts of plants, mixed with secretions from the bees' hypopharyngeal glands, wax glands and other glands, and processed and transformed by the bees. Propolis is an opaque solid, brown, reddish-brown or grayish-brown in color, sometimes with a greenish tinge, and in a few cases nearly black. Natural fresh propolis has a resinous fragrance and is sticky and malleable. It begins to soften at 36°C, becomes hard and brittle and can be pulverized at 15°C, and melts into a viscous liquid at 60-70°C. Propolis is a resinous substance, highly soluble in ether, chloroform, acetone,

Research progress on the mechanisms by which porcine circovirus type 2 infection causes immunosuppression
Circovirus infection is a newly discovered infectious disease. The disease has a relatively high infection rate in pigs and occurs widely throughout the world, having become one of the infectious diseases that seriously affect the development of the pig industry. Circovirus mainly attacks the pig immune system, interfering with and destroying the body's production and maintenance of immune antibodies against disease, resulting in reduced resistance and making pigs susceptible to secondary or concurrent other diseases. In recent years, scholars at home and abroad have conducted a great deal of research on the mechanisms by which porcine circovirus invades the immune system, and certain progress has been made in the virus replication mechanism, its effects on cytokines and lymph

Research Progress on Detection Technologies for Porcine Circovirus
Porcine circovirus disease is a class of viral infectious diseases caused by porcine circovirus (PCV) infection and characterized by immunosuppression, with the main clinical manifestation being postweaning multisystemic wasting syndrome in piglets caused by PCV-2. This article reviews the research progress in recent years, both domestically and internationally, on detection technologies for this virus, including virus isolation, electron microscopy, polymerase chain reaction, indirect immunofluorescence assay, immunohistochemistry, enzyme-linked immunosorbent assay, and in situ nucleic acid hybridization. Porcine circovirus disease
