Penicillin is a type of antibiotics. It fights nasty bacteria in a human body. Penicillin is used to help many different infections caused by bacteria. Penicillin was made for the soldiers in world war one, it was to help bullet wound infections and infections caused by lost limbs. Penicillin is made from extracting it from mould.
The purpose of this lab is to examine the internal organ systems of vertebrate that has similar internal organ systems of a human. Additionally to be able to identify where organs of the digestion, circulatory, and respiratory systems are located in a rat and their function according to the rat’s anatomy.
Penicillin is an antibiotic grown from a rare form of mold that is used to fight bacteria in the human body. It is an extremely helpful medicine, but humans did not always know about penicillin, and it took many scientist’s work, such as Alexander Fleming, howard Florey, and Andrew Morer to perfect the growth and use of penicillin, making it a widely available form of medicine.
Penicillin is an antibiotic used today to prevent bacteria from reproducing. Since its discovery in 1928, it has been developed into several different types that are commonly used all around the world. Events that led to the use of penicillin were an accidental discovery, but through extensive research and testing, it has been developed and produced into a useful medicine to fight off bacteria.
For this experiment, I utilized unknown number three which I later identified as Staphylococcus epidermis. I concluded that the unknown organism was Staphylococcus epidermis based on numerous tests performed in the laboratory which I will discuss in detail throughout this paper. One of the first tests performed was the Gram Stain. The Gram Stain
Antibiotics:- antibiotics are medication which destroy or slow down the growth of bacteria, they are used to treat infections which are caused by bacteria. Most of the time the body’s immune system can fight off bacteria but in cases in which the body cannot antibiotics are used to destroy them. Antibiotics are either given orally, applied to the skin in ointment form or injected, this all depends on the type of infection the body is currently trying to fight off, for example skin infections are treated with ointment, oral antibiotics are used to fight of moderate infections and injective antibiotics are most commonly used in
The antibiotics will have different zones of inhibition on different bacteria. Also, a range of concentrations of the nutrients in the bacteria will change the bacterial growth.
1 and 3). This antibiotic is effective against both gram positive and negative bacteria, so it would be effective against Staphylococcus epidermidis. This antibiotic is able to kill bacteria by interfering with the cell wall synthesis, weakening it, and causing its death. However, just like with Penicillin, some bacteria have become resistant to this antibiotic (6). The hypothesis stated that Staphylococcus epidermidis would be susceptible to Ampicillin because although some bacteria have become resistant this one has not (7). According to the class data, two of the tests resulted in in susceptibility, one resulted in an intermediate effect, and the rest were resistant (see Figs. 2 and 5). It seems that Staphylococcus epidermidis is in the process of becoming resistant to Ampicillin because of the varied data. However, the group data did not support the hypothesis that the bacteria would still be
It also helps with the prevention of PCP in HIV-positive patients, but should be used cautiously due to the incidence of adverse reactions. This drug is also active against many strains of gram-positive pathogens including: Streptococcus pneumoniae, Staphylococcus aureus, Group A beta-hemolytic streptococci, Nocardia, Enterococcus. It also has activity against many gram-negative pathogens, such as: Acinetobacter, Enterobacter, Klebsiella pneumoniae, Escherichia coli, Proteus mirabilis, Shigella, Xanthomonas maltophilia, and Haemophilus influenzae, including ampicillin-resistant
Penicillin inhibits the enzyme that is the cross link of pepitogylcin within the cell wall. This destroys the cell wall and exposes the inside of the cell to the external environment causing cell lysis. Penicillin is effective against gram-positive for this reason because of their thick cell walls that are full of pepitogylcin, as well as staphylococci and streptococci due to cell structure. Unfortunately, many bacteria strains have built resistance to Penicillin due to excessive use.
