If Alexander Fleming and his acquaintances had tested penicillin on guinea pigs instead of mice, we might not have this antibiotic today. Penicillin is toxic to guinea pigs; it can cause diarrhea and even death if there are too much gram-positive bacteria in the guinea pig. This antibiotic, however, is not toxic to humans and most animals, but is to very few.
The antibiotic, penicillin, comes in many forms, all are used to help heal infections.
Penicillin was not well known until November 19, 1999 at Alexander Fleming's Laboratory Museum in London. The antibiotic was discovered in the 1940s, and is one of the best moves in therapeutic medicines.
Penicillins are used to fight against multiple infections in the body. Yet, many bacteria don't react to penicillin.

Apologia Biology: How are Infectious Disease Microbes Transmitted?
How are infectious disease microbes transmitted?
A. Well, if a person has a disease and drinks a cup of water and then another person drinks out of the same cup, that person would most likely get the same disease. Why? Because the person with the disease put saliva in the water and on the cup. This spreads the disease.
B. If a stray dog bites a person and that person breaks flesh, that person could get a disease from the dog's germs.
C. If person puts a pair of shoes on that belong to someone else who happens to have athlete's foot, that person would end up getting that disease.
D. If a stray cat scratches a person and that person breaks flesh, the germs from the cat's claws could spread diseases to that person.

Apologia Biology: Fungi
Fungi: They are multi-cellular organisms that come in many separate categories. Fungi can't secrete their diet out of the terrain, so they feed on other organisms. Fungi can cause diseases.
Apologia Biology: Protozoa
Protozoa: They are single-celled parasites who thoroughly enjoy moisture and spread diseases through water a lot. Additionally, these microbes are known as parasites; therefore, they feed off various populations, sometimes humans. Some engender intestinal infections.
Apologia Biology: Viruses
Viruses: In order to reproduce and grow, viruses have to be associated with an active species. The habitat of a particular parasite is commonly referenced as your average host. They can make our bodies very ill if they enter, but there are treatments for these viruses.
Apologia Biology: Bacteria
Bacteria: They are single-celled, very small creatures who obtain their food from where they live, sometimes meaning the anatomy of a homo sapien in order to survive. Reproduction can take place in the interior or on the exterior of the homo sapien. Some bacteria inside the body can cause infections. Conversely, there are also some beneficial bacteria. These bacteria live in our intestines and put to work the nutrients we eat and the remains will be made into waste. Also, scientists use some bacteria for vaccines and medicines.
Apologia Biology: What is a Microbe?
What is a microbe?
Answer: A microbe is a single-celled creature that cannot be seen with the naked eye. They tend to be good and very useful; they take a part in helping us eat and breathe. Some, however, are the opposite making organisms quite sick. One thing that is cool about microbes is that they are known to be the first organisms on earth. There are four major kinds of microbes: bacteria, viruses, fungi, and protozoa.
