You need to be more specific in what you're asking. Is penicillin effective against *what*? There are several types of "cillins" and two major types of "Penicillins". They are mainly used for Group A strep infections, (strep throat, tonsillitis) pneumoccocal infections (pneumonia) , rheumatic fever and some other systemic (in the body) infections (such as gonorrhea and other sexually transmitted diseases). Unfortunately, because people do not take their prescribed doses correctly and since doctors have been giving people antibiotics to people for colds and flu, which do not respond to antibiotics, a lot of the types of germs that ARE susceptible to antibiotics have become immune the "older" ones like penicillin. Now the phamaceutical companies have to come up with stronger, different types of antibiotics to kill these "super bugs" that have mutated and become resistant to drugs like penicillin. So...depending on what type of infection you have, penicillin may or may not be effective.
First let me say I am not a doctor, but I will attempt to give my best understanding of the question. Obviously penicillin has been around as a long time medication, and one should always consult one's physician/doctor for advice on any medication. Having said that, penicillin, to my knowledge, has been widely used to combat Infectious Diseases, and infection in general. (mostly bacterial I think, but again this is not a quote or medical statement of fact). With regards to the term "toxic" I believe this term refers more to the word "poisonous". I suppose either of these terms/words could relate to penicillin in this case, but are possibly not the best choice. I believe the term more commonly used here would be "allergic". Some people are allergic to penicillin, while others are not, as with many other things besides medications, such as shellfish, or peanuts. So I suppose it depends on each individual person regarding penicillin - consult a physician/doctor.
penicillin kills all the bacteria around it
No Penicillin is not effective on viral infections.
Penicillin is effective against secondary infections of cancer. It is no cure for cancer.
gram-positive bacteria
by medications such as penicillin or erythromycin. Erythromycin appears to be more effective than penicillin.
Yes.They are among the most preffered antibiotics for pneumonia.
Penicillin is NOT effective against gram positive and negative cocci and gram positive bacilli only. it is not effective against rest of the organisms.
No- because penicillin inhibits cell wall synthesis and Mycoplasmas don't have a cell wall.
Penicillin exhibits the property of an effective and safe antimicrobial therapy that involves selective toxicity. This is because the chemical structure of Penicillin gives antibacterial properties.
Penicillin is still the most effective treatment for rheumatic fever. A 10-day course of penicillin by mouth, or a single injection of penicillin G is the first line of treatment
Penicillin is effective for some infectious diseases, like strep throat and syphilis. It does not cure most infectious diseases.
