Highly concentrated amounts of alcohol (70% and higher) can kill bacteria by damaging the plasma membrane and denaturing proteins within the cell.
Gram-negative bacteria are more vulnerable to alcohol because they contain a thin peptidoglycan cell wall covered by an outer membrane. The outer membrane controls the passage of substances into and out of the cell. Alcohol dissolves the outer membrane. This allows substances that are normally blocked by the membrane to easily enter the cell through the thin peptidoglycan cell wall. In addition, cell contents leak out of the cell through the cell wall.
Gram-positive cells lack outer membranes and rely solely on thick peptidoglycan cell walls to protect them from the environment but can still be killed by alcohol.

ReneAlcohol can help kill bacteria in the throat, but it can also irritate the throat lining. It is generally not recommended to consume alcohol when experiencing a sore throat. Instead, it is better to rest, stay hydrated, and use throat lozenges or warm salt water gargles for relief.

When bacteria invades your body what kind of relationship is between you and sore throat?
Most sore throats are caused by viruses - which is why taking antibiotics like penicillin is a complete waste of time, and can often make the condition worse. If it is bacterial, it could be a staphlococcus or a streptococcus. In the old days diptheria used to give you a pretty nasty sore throat, before it killed you. If you want numbers, think in hundreds of thousands of bacteria in the mouth and throat - all the time, but not always the bad ones, fortunately. Some sore throats are not due to infection at all, but some form of glandular inflammation, or mechanical irritation. as many as the doctors and scientist say
Is a crushed aspirin better than salt water gargle for sore throat?
Both crushed aspirin and salt water gargle can help alleviate a sore throat. Aspirin contains anti-inflammatory properties that can reduce pain and inflammation, while salt water gargle can help reduce swelling and kill bacteria in the throat. It is best to consult with a healthcare professional to determine the most suitable treatment for your sore throat.
What does pink on agar means?
Pink on agar can indicate the presence of certain bacteria, such as lactose-fermenting coliforms like E. coli. In some media, the pH indicator turns pink when bacteria metabolize lactose, producing acid as a byproduct. This can help in distinguishing different microorganisms based on their metabolic capabilities.
