As cells grow and grow, they excrete more or less acidic substances, such as lactate and the like, so the culture medium will probably become acidic, and the gel used is the kind of "allergic constitution" in which it is thinner when the pH is high and thicker when the pH is low. By looking at how thick the gel is, we can see how much the small bacteria have grown. By calculating the proportion of thickness change, we can know the strength of the antibiotic's inhibitory effect on bacteria.
**The bacteria used in Escherichia coli (E. coli) are the most prevalent coli.), which is the most common kind in the toilet, and the concentration of antibiotics is 1ug What is the concept?
As for our ultimate boss, it is CIP, ciprofloxacin, also known as ciprofluperic acid, and the drug made of it is called full rehabilitation. <>

Broad-spectrum means that the drug is effective against a wide range of microorganisms, substances, or diseases.
Guangpu is a Chinese word, pronounced guǎng pǔ.
Now there are broad-spectrum antibiotics, broad-spectrum antibiotics refer to drugs with a wide antibacterial spectrum, simply put, drugs that can resist most bacteria, and a narrow-spectrum antibiotic, which is a drug that specializes in killing a certain type or class of bacteria.

There are many variety.
At present, the antibiotics used in clinical practice mainly include the following categories:
1. Penicillins.
2. Cephalosporins.
3. Aminoglycosides.
4. Macrolides.
5. Tetracyclines.
6. Chloramphenicol.
7, lincoamide.
8. Polypeptides and other antibiotics.

Broad-spectrum antibiotics refer to drugs with a wide antibacterial spectrum, simply put, drugs that can resist most bacteria.
Such as ceftriaxone sodium, clindamycin, gentamicin, streptomycin, oxacillin sodium, cloxacillin sodium, ampicillin sodium, piperacillin sodium, penicillin potassium, cefuroxime sodium injection, cefradine and so on.

Antibiotics with a wide range of antimicrobial range. For example, chloramphenicol, chlortetracycline, oxytetracycline, tetracycline, sulfoxide spike chandin, etc. It can not only strongly inhibit most of the gram-negative bacteria and gram-positive bacteria, but also inhibit rickettsia, spirochetes and some protozoa.
However, due to the disruption of the normal balance of the microbiota in the body, additional infections with insensitive microorganisms such as Candida may occur.
Broad-spectrum antibiotics refer to drugs with a wide antibacterial spectrum, simply put, drugs that can bury enough to resist most bacteria, and a narrow-spectrum antibiotic, which is a drug that specifically kills a certain type or class of bacteria. Broad-spectrum antibiotics are mainly used when the pathogenic bacteria are not yet known, but sterilization is needed, and when the pathogenic bacteria are identified, it is necessary to use narrow-spectrum antibiotics to specifically sterilize. Overdose of antibiotics is not good for the body.
