Thekey difference between Streptomyces and Streptococcusis that链霉菌is a genus of革兰氏阳性filamentous bacteria, while链球菌is a genus of gram-positive coccus or spherical bacteria.
Pathogenic bacteria are bacteria that can cause diseases. Most species of bacteria are harmless and beneficial. However, some bacteria can cause infectious diseases. The pathogenic bacteria species that can cause human infections are estimated to be fewer in number. Pathogenic bacteria are specially adapted and endowed mechanisms that can overcome the body’s innate and adaptive immune defenses. These bacteria, therefore, can invade different parts of the body, including blood, lymphatic system, skin, mucus, respiratory system, gastrointestinal system, and brain.链霉菌和链球菌是引起人类感染的致病细菌的两个属。

What is链霉菌?
链霉菌is a genus of gram-positive filamentous bacteria. They are有氧细菌. Over 500 species of链霉菌细菌已经被鉴定出来。链霉菌species produce well-developed vegetative hyphae 05-2 µm in diameter with branches. They form a complex substrate mycelium that aids in scavenging organic compounds. Though the mycelia and aerial hyphae that arise from these bacteria are motile, mobility is achieved through the dispersion of spores. The surfaces of spores are hairy, smooth, rugose, spiny, or warty.
基因组链霉菌contains high G-C content. The complete genome of the strain链霉菌coelicolorA3(2)于2002年发布。该菌株的染色体长8,667507bp长,GC含量为72.1%。预测该菌株的基因组包含7,825个蛋白质编码基因。该属的物种主要在土壤和腐烂的植被中发现。此外,它们因其独特的泥土气味而闻名,这是由于生产挥发性代谢物(Geosmin)的产生的结果。此外,这些细菌物种可产生超过三分之二的临床重要抗生素,包括新霉素,小骨霉素,格里斯基霉素,肉豆蔻霉素和氯霉素。链霉菌物种是罕见的病原体。他们造成infections such as mycetoma and放线菌病(S. somaliensis and S. sudanensis)在人类中。该属的某些物种是植物病原体,例如S. turgidiscabies(scab disease in potatoes) andS. ipomoeae(红薯中的软腐病)。
What is链球菌?
链球菌is a genus of gram-positive cocci or spherical bacteria. The cell division in链球菌species occurs along a single axis. As they grow, they tend to form pairs or chains that may appear bent or twisted. These bacterial species are different from葡萄球菌,which divide along multiple axis, thereby generating irregular clusters of cells. Most链球菌物种是过氧化氢酶阴性和氧化阴性的。链球菌species are facultative anaerobes.
目前,该属中已经确认了50多种物种。此外,已经发现该属是唾液微生物组的一部分。大多数链球菌基因组的大小为1.8至2.3 MB。这些基因组编码1700至2300蛋白。此外,链球菌species cause different diseases such as链球菌(pharyngitis, cellulitis, erysipelas),S. agalactiae(新生儿脑膜炎和败血症),S. gallolyticus(心内膜炎,尿路感染),S. anginosus(respiratory infections),S. mutans(dental carries),S. pneumonia(pneumonia).
之间有什么相似之处链霉菌和链球菌?
- 链霉菌和链球菌are two genera of pathogenic bacteria.
- The bacterial species in both genera are gram-positive.
- 他们造成infections in humans.
- The bacterial species in both genera have virulent factors.
- The diseases caused by bacterial species of these genera can be controlled by selective antibiotics.
What is the Difference Between Streptomyces and Streptococcus?
链霉菌是革兰氏阳性丝状细菌的属,而链球菌is a genus of gram-positive coccus or spherical bacteria. Thus, this is the key difference between Streptomyces and Streptococcus. Moreover, over 500 species have been recognized in the链霉菌属。另一方面,已确认了50多种链球菌属。

摘要 - 链霉菌与链球菌
链霉菌和链球菌are two genera of pathogenic bacteria that cause human infections.链霉菌是革兰氏阳性丝状细菌的属,而链球菌is a genus of gram-positive coccus or spherical bacteria. So, this summarizes the difference between Streptomyces and Streptococcus.
