How much do you know about pathogenic microorganisms?

As an ICU doctor, I often have to face various infectious diseases

Microorganisms are simple in structure, mostly single-celled, or even without cellular structure, and require the help of microscopes or even electron microscopes to see them

Scientists usually divide pathogenic microorganisms into three categories: 1) Noncellular microorganisms

There is a kind of non-cellular pathogenic microorganism called prion, which may not be familiar to everyone, but it is famous when it comes to the "mad cow disease" it causes

2) Prokaryotic microorganisms

Actinomycetes are a special kind of Gram-positive bacteria, but their morphology and reproductive characteristics are more like fungi

Mycoplasma, chlamydia, and rickettsia are not familiar to everyone.

3) Eukaryotic cell type microorganisms

Protozoa are also unicellular eukaryotes, widely distributed in nature, more than 65,000 species have been found so far, although small in size, they can independently complete all the physiological functions required for life activities

For clinicians, when encountering an infected patient, they must determine the pathogen causing the patient's infection through medical history analysis and laboratory examination, so as to select the correct anti-infective drug in a targeted manner
