Alpha-hemolytic Streptococcus

There are many different types of germs in the air, some of which are highly pathogenic, while others are relatively weaker. Some people developed symptoms such as tonsillitis, red and swollen throat, and gingival abscesses after contact with crowds. After going to the hospital for examination, the doctor said that they were infected with type alpha hemolytic streptococcus. So what kind of germ is this? Next, let us learn more about this pathogen through the following text.

2. Concept

Hemolytic Streptococcus, also known as Saperin, is sensitive to heat and chemical disinfectants and often causes infections of the tonsils, pharynx, middle ear, etc. It is also the pathogen of pyelonephritis, puerperal fever, and scarlet fever. It can be divided into three different types, among which type alpha (α) hemolytic streptococcus is one of them. It is also called grass-green streptococcus, also known as type A hemolytic streptococcus. There is a 1-2mm wide grass-green hemolytic ring around the colony, and the red blood cells in the ring are not dissolved. It usually resides in the human oropharynx, respiratory tract and intestines.

Symptoms

It has typical symptoms of respiratory diseases such as periodontitis, tonsillitis, pharyngeal redness and swelling, and gingival abscess.

4. Diagnosis

Microbiological examination methods are used, and specimens such as pus, throat swabs, and blood can be sent for examination depending on the disease caused by streptococci. The colonies of type alpha hemolytic streptococci are gray needle-shaped, with a transparent hemolytic ring of about 2 mm around the colonies.

IV. Hazards

This type of bacteria is not highly pathogenic and is mostly conditional pathogens. Alpha-hemolytic streptococci normally parasitize in the human respiratory tract and intestines, but can sometimes cause subacute endocarditis and other symptoms.

5. Treatment

Children with acute pharyngitis and tonsillitis must be treated thoroughly to prevent the occurrence of acute glomerulonephritis, rheumatic fever, and subacute bacterial endocarditis. Treat patients and carriers promptly to reduce the source of infection.

6. Prevention

1. Hemolytic Streptococcus is widely distributed in nature, existing in water, air, dust, feces, and the oral cavity, nasal cavity, and throat of healthy people and animals. It can be transmitted through direct contact, air droplets, or through skin and mucous membrane wounds. Therefore, when we come into contact with others, we should pay attention to maintaining an adaptive distance.

2. When eating food, especially cooked food, be sure to purchase it from regular markets or supermarkets.

2. You should eat more vegetables and fruits, and strengthen physical exercise to enhance your ability to resist viruses.

3. During holidays, try not to go to crowded places.

4. Pay attention to isolation from patients to prevent being infected with the disease.
