coagulase的音標是[k?u??gj?l?si?z]，基本翻譯是凝集素。速記技巧可以是：/k?u/（發音時，先發“科”的音，然后迅速滑向“聚”的音）+ /l?/（發長音“勒”）。

coagulase這個詞源自希臘語“κοαγωγη?”，意為“凝固的”。它的主要功能是幫助細菌產生凝集，從而阻止血液的凝固。

英文小作文：

Coagulase is an enzyme that helps bacteria clump together and form a solid mass, which is known as a biofilm. It is commonly found in bacteria such as Staphylococcus aureus, which can cause various infections in humans and animals. Coagulase-positive staphylococci are particularly dangerous because they can cause severe infections that are difficult to treat due to their ability to form biofilms and resist antibiotics. On the other hand, coagulase-negative staphylococci are more common and can cause mild to moderate infections that are easier to treat with antibiotics. Understanding the role of coagulase and its importance in the treatment of bacterial infections is crucial for effective prevention and management of these diseases.
