Difference Between Fastidious and Nonfastidious Bacteria

The key difference between fastidious and nonfastidious bacteria is thatfastidious bacteria require special nutritional supplements and conditions to grow while nonfastidious bacteria do not need such special nutritional supplements or conditions.Furthermore, fastidious bacteria show slow growth in contrast to nonfastidious bacteria, which grow fast.

细菌很小单细胞有机体。他们是prokaryotic和microscopic. They require nutrients and certain conditions to grow and multiply. There are two types of bacteria as fastidious and nonfastidious bacteria.

What are Fastidious Bacteria?

Fastidious bacteria are bacteria that need an addition of special nutritional supplements and maintenance of proper conditions to grow. In other words, they are bacteria which have a complex nutritional requirement. They exhibit a slow growth on琼脂盘子。他们还需要更多时间来繁殖。通常，当大气条件与所需的细菌不同时，这些细菌将无法生长。无法快速生长是由于它们无法合成所需的有机分子。

挑剔的细菌也引起抗菌易感性测试的困难。Neisseria gonorrheae,弯曲杆菌物种，Lactobacillus物种，Helicobacter物种，和haemolytic Streptococci are examples of fastidious bacteria.

What are Nonfastidious Bacteria?

Nonfastidious bacteria are bacteria that grow fast in agar plates without special nutritional supplements or conditions. They are able to grow and replicate rapidly. In fact, they are able to synthesize all organic molecules required for their growth, unlike fastidious bacteria.

在正常的大气条件下，他们在实验室媒体中没有问题。这是因为他们拥有简单的营养要求。他们还能够在正常的大气条件下生长。葡萄球菌和链球菌是两个非固定的细菌属。

What are the Similarities Between Fastidious and Nonfastidious Bacteria?

• 细菌是微生物。
• 他们是单细胞有机体。
• 两者都在培养基中生长。
• They multiply by binary fission.
• Both these bacteria groups cause diseases.

What is the Difference Between Fastidious and Nonfastidious Bacteria?

Fastidious vs Nonfastidious Bacteria
细菌是细菌，需要特殊的营养补充剂和条件才能在琼脂板上生长。	Nonfastidious bacteria are bacteria that do not need special nutritional supplements and conditions to grow on agar plates.

Antimicrobial Susceptibility Testing
Cause problems in antimicrobial susceptibility testing due to their special requirements and slow growth	Do not cause problems in antimicrobial susceptibility testing.
Ability to Grow in Laboratory Media and under Normal Atmospheric Conditions
Difficult to grow	Easy to grow
复杂的营养需求
Have a complex nutritional requirement	没有复杂的营养要求

概括– Fastidious vs Nonfastidious Bacteria

Fastidious and nonfastidious bacteria can be distinguished based on the nutritional requirement. Fastidious bacteria need special supplements of nutrients in order to grow. Unless required nutrients and proper growth conditions are available, they do not grow or show a very slow growth. In contrast, nonfastidious bacteria grow fast on laboratory media under normal atmospheric conditions. They synthesize their organic molecules. Hence, special nutritional supplements are not necessary for their growth. Furthermore, they don’t cause problems in antimicrobial susceptibility testing as well. Overall, this is the difference between fastidious and nonfastidious bacteria.
