Yes, because the semi-synthetic penicillin contains additional feature in its side chain which some how protects the beta-lactam moiety from beta-lactamenase, an enzyme which works against the beta-lactam moiety of natural penicillin.

What is semisynthetic media?
Semisynthetic media is a type of culture media used in microbiology that contains both natural and synthetic components. This type of media allows for more control over the specific nutrients provided to the microorganisms being cultured, compared to natural media. By combining natural substances with synthetically derived ingredients, semisynthetic media can offer a more defined and reproducible environment for microbial growth.
How was diphtheria treated in the 1800's?
by medications such as penicillin or erythromycin. Erythromycin appears to be more effective than penicillin.
Is penicillin more effective against Gram negative or Gram positive?
Gram Positive
Why is penicillin not as effective as it was fifty years ago?
This isn't entirely true. Penicillin is still as effective against the bacteria that it combated 50 years ago, but new strains of penicillin resistant bacteria have evolved since 50 years ago. This means that penicillin is less effective against a larger percentage of bacteria than it was 50 years ago, solely because of the new, anti-biotic resistant strains.

Has penicillin changed over the years?
Penicillin has not changed over the years from it's invention in 1928. You have developed some derivatives of penicillin, discovered for more than half century ago. You have penicillin V, injection procaine penicillin, injection benzathine penicillin. Then you have semisynthetic penicillins like ampicillin and amoxicillin. Then you have carboxypenicillins like carbenicillin and ureidipenicillins like piperacillin.
Which is more effective acquired or natural intelligence?
I think that the natural intelligence is more effective, as it is something you live with, while if the person is not intelligent from the very beginning, it is more difficult to be effective in future.
When the antibiotic penicillin was first introduced it was immediately effective in combating staphylococcus bacterial infections?
1. members of the original population of bacteria that were penicillin resistant survived and reproduced, creating a more resistant populationReasonsome members of the of the original staphylococcus population had a mutation that made them penicillin- resistant. they survived and reproduced and all their offspring were also resistant to penicillin, creating a more resistant population
How have bacteria evolved resistance to penicillin?
natural selection, if a victim of a bacterial disease takes penicillin and the bacteria survives it is spread and reproduces, but those that don't have more resistance are either destroyed or have lower numbers
What drug treats diphtheria?
Both adults and children may be given penicillin, ampicillin, or erythromycin. Erythromycin appears to be more effective than penicillin in treating people who are carriers because of better penetration into the infected area.
Which is more cost effective in the home a gas or elecrtic range?
Natural gas is generally more cost effective since it cooks quicker and costs less.
Why do doctors prescribe amoxicillin instead of penicillin for tonsiitis?
amoxicilin is a semi-synthetic form of penicillin. After the penicillin is extracted, some of it is converted to amoxicillin. penicillin is primarily for gram+ bacteria while amoxicillin is effective against both gram positive and gram negative bacteria.Amoxicillin is better absorbed than penicillin as it can withstand the acidity of stomach juice better than penicillin releasing more antybiotics in to blood stream.
Why is penicillin not effective anymore?
Penicillin does still work, just not as well. This is because the few germs that can survive the antibiotic will then pass on that capabaility to their progeny; the basics of genetics in action. This means that later generations of the same bacteria need more to kill them or, even worse, are entirely immune to the effect of penicillin. Some strains of bacteria have evolved to the point that they are not only unaffected by penicillin itself, but all drugs similar to penicillin (beta-lactams). One such strain is MRSA (methicillin-resistant Staphylococcus aureus).
