What is Torus?

The bright spots on the photos of the dark matter circle are galaxies, and the blue part is the dark matter distribution obtained from the gravitational lens. It can be seen that dark matter forms a ring around the galaxy cluster.Astronomers believe that this implies that the galaxy cluster has collided with other galaxy clusters.The dark matter of the two galaxy clusters attracted and dragged each other while leaving the ring structure. .

The protein encoded by ORF2 gene is the main structural protein of porcine circovirus type 2, and this protein has good immunogenicity. In this experiment, the ORF2 gene fragment was excised from the recombinant plasmid pMD18-T-ORF2, cloned into the vector pEGFP-C1, and the frame-shifting base was excised. Epidemiological investigation of porcine circovirus disease in Wuling Mountain area.

1. Sick pigs and poisoned pigs are the main source of infection. The boar semen can be poisoned. The sow can be transmitted through mating. The sow is also a carrier of many pathogens. Detoxification through a variety of channels or the infection of suckling piglets through the placenta, causing Early infection of piglets, so it is important to clear the pigs and clean the farm;
2. Porcine circovirus is prone to infect pigs with multiple bacteria or secondary multiple bacterial infections. Once this is the case, the consequences will be more serious. Therefore, comprehensive prevention and control measures must be taken to prevent bacterial concomitant or secondary infections to control the disease. Important measures; good disinfection measures, select high-efficiency disinfectants, such as double-chain quaternary ammonium salt iodine, glutaraldehyde and so on.
3. Rats can spread a variety of diseases. If rodent damage is not controlled well, it will easily cause disease. Therefore, rodent damage must be controlled.
4. Drug control This is mainly caused by viral infection or secondary infection, so it is recommended to take better antiviral drugs, such as astragalus polysaccharide injection. It can induce the body of livestock and poultry to produce interferon, promote the formation of antibodies, and achieve the purpose of anti-virus. It can enhance the function of heart, liver, kidney and other organs of livestock and poultry, improve microcirculation; improve the immunity of the body; can enhance the phagocytosis of macrophages, stimulate the function of T and B lymphocytes, and enhance the killer cells related to cytokines active. The diseased pigs were injected intramuscularly. The animals were injected with 0.1-0.2 ml (1%) per kilogram of body weight twice a day for 3 to 5 days.
