In the golden autumn season, it is the corn harvest season again. It is soft, glutinous and sweet, and Mr. Chen loves it very much. I knew he loved to eat corn, and this year the corn harvest was good, Mr. Chen's relatives gave him a large bag. However, he did not preserve it well. In a few days, the corn became moldy and opened the bag and smelled moldy. He was usually frugal and reluctant to throw it away, so he continued to cook and eat it.
has COPD , he likes to cough, phlegm and asthma on weekdays. After eating corn, he coughs, phlegm and asthma become even worse. He thought he had an acute attack on COPD like in previous years, so he went to the local hospital to hang a bottle, but no matter how he hanged the bottle, he didn't get better. Moreover, he had a fever and couldn't eat it, which made his family very anxious. Finally, Director Xu Liyu, who rescued him two years ago, was found.
Director Xu Liyu of the Department of Respiratory and Critical Care Medicine of Fuzhou First Hospital compared Mr. Chen with the lung CT scan two years ago. He found that the infection was significantly worse (as shown in Figures 1 and 2), but the general anti-inflammatory and anti-asthma treatment did not improve significantly. Director Xu suspected that Mr. Chen had a special bacterial infection and recommended a bronchoscopy. After bronchoscopy and genetic testing of alveolar lavage fluid, it was found that it was an Aspergillus infection. Finally, for the treatment of Aspergillus , Mr. Chen's fever finally got better.
- What is Aspergillus?
Aspergillus filamentous fungus is a conditionally pathogenic fungus. Normal people have a certain resistance to it. Infection is more common in people with low immunity, such as tumor patients, people who have long used the immunosuppressant , etc. Mr. Chen was infected with Aspergillus mainly because he had COPD and impaired immune function.
- Where does Aspergillus originate?
Aspergillus prefers hot and humid environments. The detection rate of aspergillus is particularly high in foods in tropical and subtropical regions. It is more common in moldy grains, grain products and other moldy organic matters, such as moldy foods such as corn, macaroni , milk, dairy products, cooking oil, etc.
- How to prevent Aspergillus infection?
First of all, keep the environment dry and ventilated so that molds can not have an environment for growth. Secondly, if you find that the items are moldy, you should be isolated and protected when dealing with moldy items, wear masks, gloves, or even hats and shoe covers, and change clothes in time after dealing with moldy items. According to , Mr. Chen recalled that he was exposed to a large amount of moldy corn without any protection. A large number of Aspergillus spores floated in the air and were brought into the lungs through breathing to cause disease.
