Autumn is coming. In the process of raising pigs in autumn, it is easy for pigs to get some hidden diseases. For example, what are the hazards of pig mycoplasma disease that we are talking about today? Can you think of mycoplasma disease or the accomplice of "blue ear disease"?
Hazards of Mycoplasma hominis:
1. "Portal disease"
Mycoplasma specifically destroys the ciliated epithelial cells of the respiratory tract of pigs, causing the cilia to lose the ability to remove foreign bodies and pathogens. The three protective barriers of the important respiratory system of the pig's respiratory tract will be opened, and the pathogenic microorganisms will be invaded, and various infections or infections will follow. Come, so mycoplasma is called "portal disease."
Note: Three barriers to the porcine respiratory defense system: nasal cavity, tracheobronchial, and pulmonary macrophages.
Nasal cavity: Filters and blocks dust, particles, etc. from the air; it also acts as a humid air.
Respiratory cilia: Remove more than 95% of various pathogens and dust particles from the respiratory tract.
Pulmonary macrophages: immune regulation, eliminating viruses.
2, immunosuppression
Mycoplasma hyopneumoniae often inhibits the immune system of pigs. Mycoplasma pneumoniae inhibits the growth of macrophages and has an important effect on B lymphocytes and T lymphocytes.
3, induced consumptive diseases
Mycoplasma is highly infectious and pathogenic.
The common streptococcosis in pig farms, Haemophilus parasuis, Pasteurella, and blue ear disease all have "participation" of mycoplasma.
Take blue ear disease as an example: Mycoplasma destroys the cilia on the trachea and bronchial epithelial cells, opens the defense portal of the respiratory tract, and makes the blue ear virus easily invade the body.
On the other hand, mycoplasma can affect the immune response of the local organs of the lungs, reduce the phagocytic ability of alveolar macrophages, and make the colonization and replication of the blue ear virus particularly easy. Mycoplasma is the "accomplice" of blue ear disease! Therefore, to control blue ear disease, we must first control mycoplasma.
Please ask the pig farmers to understand that due to the high temperature in the autumn, pigs often have swollen asthma, and many pigs have cough and other symptoms, which are caused by mycoplasma diseases. Therefore, everyone must pay attention to the harm caused by mycoplasma and prevent it in time!
An insulin injection pen is a medical device used to administer insulin to people with diabetes. It looks like a pen and contains a cartridge filled with insulin, a needle, and a mechanism for delivering the insulin dose. The pen is designed to be easy to use and is often preferred by patients over traditional syringes and vials. The insulin injection pen is available in different types, such as reusable and disposable pens, and can be used with different types of insulin. It is important to follow the instructions provided by the healthcare provider or pharmacist when using an insulin injection pen to ensure proper dosing and injection technique.
