α和β溶血之间的差异

关键区别 - alpha vs beta溶血

红细胞是我们血液中最常见的血细胞类型。它们是由骨髓。它们对于将氧气从肺部和心脏和整个身体携带很重要。红细胞包含hemoglobin分子。血红蛋白是一种含铁金属oprotein, and it is the main molecule of oxygen transportation. Hemoglobin molecules are located inside the red blood cells. The destruction of the red blood cells causes the release of hemoglobin from the red blood cells to theblood plasma。这个过程称为溶血。几种特定类型的细菌会产生一种称为helsolysin的酶，可催化红细胞的崩溃。溶血分为三种。α溶血，β溶血和γ溶血。在α溶血中，红细胞部分分解，而在β溶血中，红细胞被细菌酶完全分解。这是关键区别between alpha hemolysis and beta hemolysis.

什么是α溶血?

α溶血也被称为不完全溶血，是红细胞部分破坏的过程。该过程被称为α-溶血素的细菌溶血酶催化。几种细菌物种是α溶血的原因，它们是S. pneumoniae，，，，链球菌炎，，，，S. Mutans，，，，andS.唾液。

When these bacteria are grown in血琼脂由于红细胞的不完全破坏，培养基周围的菌落周围绿色呈绿色。绿色是由于biliverdin的存在，该化合物是血红蛋白分解的副产品。

什么是β溶血？

Beta hemolysis also known ascomplete hemolysis，是红细胞完全破坏的过程。这细胞膜of the red blood cells destroyed by the bacterial hemolytic enzymes. Therefore, the hemoglobin molecules release into the blood plasma. Beta hemolysis occurs due to the bacterial enzyme called beta-hemolysin.

分泌该酶的细菌被称为β溶血细菌，常见物种是S. pyogenesandS. agalactiae。When these bacteria are grown in blood agar medium, they release beta-hemolysin into the medium. Beta hemolysins break down the red blood cells completely. Hence, clear zones are produced around the bacterial colonies. Beta hemolysis is identified by the clear zones produced around the bacterial colonies.

What are the Similarities Between Alpha and Beta Hemolysis?

• α和β溶血是两种类型的溶血。
• In both processes, bacterial enzymes are involved.
• 红细胞are affected by both processes.

What is the Difference Between Alpha and Beta Hemolysis?

Alpha vs Beta Hemolysis
Alpha Hemolysis is the process of incomplete destruction of red blood cells in the blood.	β溶血是血液中红细胞完全破坏的过程。
Red Blood Cells
在α溶血中，红细胞完全分解。	在β溶血中，红细胞部分分解。
琼脂培养基中的血液指示
Alpha Hemolysis indicates the production of clear zones around the bacterial colonies on blood agar plates.	β溶血表明血琼脂板细菌生长周围的绿色。
Enzyme Involved
α溶血是由酶α-溶血素催化的。	β-溶血素催化β溶血。
Bacteria Involved
α溶血细菌是肺炎，，，，链球菌炎，，，，S. Mutans，，，，andS.唾液。	Beta Hemolytic bacteria arepyogenesandS. agalactiae。
同义词
α溶血也称为绿色溶血，不完全溶血或部分溶血。	β溶血也称为完全溶血。

概括 -Alpha vs Beta Hemolysis

溶血是细菌酶对红细胞的分解。当红细胞的细胞膜破坏时，血红蛋白分子泄漏到血浆中。参与溶血的酶被称为溶血素。许多细菌能够产生血素酶。溶血反应有三种类型。α溶血，β溶血和γ溶血。在α溶血中，发生不完全的红细胞分解。因此，在血琼脂板上生长的细菌菌落周围产生了绿色区域。在β溶血中，会发生完全破坏红细胞。因此，在血琼脂板中的细菌菌落周围产生了清晰的区域。 This is the difference between alpha hemolysis and beta hemolysis. Hemolytic anemia is the disease condition that occurs due to the excessive destruction of red blood cells in the blood.
