CATDOLL : CATDOLL: What are cocci? To which group of streptococci does oral streptococci belong?

1. What are cocci?

Cocci are shaped like a ball, so they are called cocci. However, according to their arrangement, they are divided into single cocci, diplococci, streptococci, tetracocci, sarcina and staphylococci, which are named according to their shapes. Streptococci and staphylococci are the most common pathogens. Streptococci are the most common in upper respiratory tract infections, while staphylococci are the most common in purulent infections.

2. To which group of streptococci does oral streptococcus belong?

The important streptococci in the oral cavity include Streptococcus pyogenes, Streptococcus viridans, Streptococcus pneumoniae, Streptococcus agalactiae, etc. Streptococcus is a relatively common bacterial group. There are many other major bacterial groups in the oral cavity, including anaerobic bacteria, Streptococcus salivarius, etc. These bacterial groups generally do not cause illness in the human body. When the body's resistance is reduced, it can cause illness.

3. What is spongiococcus?

Spongococcus refers to a type of bacteria that is spherical or nearly spherical. Depending on the arrangement, it can be divided into monococci, diplococci, streptococci, tetracocci, sarcina, and staphylococci.

4. What is gonococcus?

Gonorrhea is also known as gonorrhea. Generally speaking, it is an infectious disease caused by sexual contact and transmission. It is mainly treated with quinolone drugs or third-generation cephalosporin drugs. It can be considered a type of bacteria and belongs to the prokaryotic cell type microorganism. It is a Gram-negative diplococcus through Gram staining, and its appearance is a double ball.

5.What are diplococci?

In pus and sputum or other environments, diplococci sometimes appear in short chains.

There are two main types of diplococci, usually called rough and smooth, the former often also called R-type and the latter S-type.

The main characteristics of rough diplococci are that the bacteria have no intercalation and the colonies are very rough, and they usually do not cause disease;

The main characteristics of smooth diplococci are that the bacteria have a cyst and the colony is very smooth, but it is a toxic strain and usually has strong pathogenicity. The main mechanism of smooth diplococci causing disease is that its cyst can protect the bacteria from being eliminated by the human body's phagocytosis, which leads to the proliferation of bacteria in the human body and causes a series of diseases, mainly including pleurisy, lobar pneumonia, sepsis, etc., and smooth diplococci can also autolyze to produce intracellular hemolytic mycin, which has a strong lytic effect on red blood cells, and the mortality rate of animals after infection is very high.

6. How to preserve hydrangea mushrooms?

There are three ways to keep wild mushrooms fresh:

First, salt preservation

Soak the newly picked wild mushrooms in 0.6% salt water for about 10 minutes after sorting them, drain them and store them in plastic bags, which can keep them fresh for 5-8 days.

The second method is to use rice soup film to preserve freshness.

Add 1% soda ash or 5% baking soda (sodium bicarbonate) to the thin rice soup used for cooking rice, and cool it to room temperature. Soak the collected wild mushrooms in the rice soup alkali solution, remove them after 5 minutes, and place them in a cool and dry place. At this time, a thin film of rice soup will form on the surface of the mushrooms, which can isolate the air and keep them fresh for 3 days.

The third type is ascorbic acid preservation.

After harvesting wild mushrooms, spray 0.1% ascorbic acid solution on the fresh mushrooms and put them into non-iron containers. They can be kept fresh for 3-5 days without changing their freshness and color.

7. How to eat hydrangea mushrooms?

Ingredients: A few shiitake mushrooms, a can of Syunsheng chicken soup, an appropriate amount of Jinhua ham, 3-5 scallops.

Exploring Chinese Noodle Culture

China has a rich and diverse food culture, and one of the most beloved traditional foods is "dried noodles". Whether in rural or urban areas, dried noodles are a common sight on Chinese tables and are considered a symbol of tradition. This article will delve into the history, production, and cultural significance of dried noodles.

Historical Origins

As one of the traditional Chinese delicacies, the history of dried noodles can be traced back to ancient China thousands of years ago. The earliest dried noodles were made by hand, kneading and rolling the dough, and hanging it to dry, hence the name "dried noodles". This production method not only retains the taste and elasticity of the noodles, but also extends their shelf life. Dried noodles are particularly popular in northern regions, such as Shanxi, Shaanxi, Liaoning and other places, and have become the staple food on the local people's tables.

As time went by, people gradually introduced the process of making noodles with machinery to improve production efficiency. However, traditional handmade noodles are still loved by many people because of their unique taste and pure natural flavor.

Production process

Making dried noodles requires a precise recipe and unique craftsmanship. Traditional dried noodles are usually made by mixing high-gluten flour and water, and then made by hand with a rolling pin. The dough needs to be kneaded repeatedly until it becomes soft and elastic. Next, the dough is cut into small pieces, rolled and stretched into long strips, and finally hung to dry.

The machine-made noodles are made with an automated process. The dough is kneaded and rolled with a certain speed and pressure by the machine, and then cut into uniform noodles by a cutting machine. During the production process, the quality and output of the noodles are guaranteed to be stable.

Cultural significance

Dried noodles have an important place in Chinese culture and are closely related to people's daily lives. First of all, dried noodles are often associated with reunions, family gatherings and festivals. Whether it is the New Year, welcoming relatives and friends or holding a festive wedding, dried noodles are a must-have food for people to celebrate. This traditional and long-standing cultural positioning has endowed dried noodles with the symbol of unity, happiness and auspiciousness.

Secondly, dried noodles also represent the Chinese people's love for food and their pursuit of excellence. Making dried noodles requires time, patience and skilled techniques, which fully demonstrates the uniqueness of Chinese cuisine. When people enjoy dried noodles, they are also praising the delicious food and paying tribute to traditional culture.

Finally, dried noodles have also become an important cultural symbol in China's foreign exchanges. In international events and exhibitions, Chinese dried noodles are often displayed as a national gift and a symbol of cultural exchange. This not only showcases China's rich and diverse food culture, but also enhances friendly relations and cultural identity between countries.

in conclusion

As a representative of traditional Chinese food, dried noodles not only have a long history and unique production process, but also carry rich cultural connotations. As Chinese people, we should be proud of our rich and diverse food culture. When enjoying the delicious dried noodles, we should also remember the cultural symbols of tradition, unity and festivity behind them.
