The History And Development Of Penicillin

Penicillin has been in existence since the early 1900’s and we have been using it to help treat and cure bacterial infections since then, but it was not developed deliberately. It was actually discovered by accident by a scientist in Scotland named Sir Alexander Fleming in 1928.

While conducting some experiments in his laboratory in London, he noticed that a dish of Staphylococcus had been cross-contaminated with Penicillium notatum. The penicillium inhibited the growth of the bacteria in a semicircle and he believed in the beginning that this was the discovery of a simple disinfectant. He saw that it was effective, but was not very toxic. He did not realize just how important his discovery was at the time and the use of penicillin as a drug did not really start until after 1939. Infectious bacteria was not much of a match for the new drug, but at the time Britain was in the middle of World War II and did not have the money that was required to make the large amount of penicillin that was required in order to do more clinical studies on its usefulness. It soon asked the United States for assistance on the matter.

Soon after a lab in Peoria agreed to assist with the production of the penicillin, a search began to find the most appropriate strain of Penicillium notatum. A strain that multiplied quickly was needed and not too long after a worldwide search began, the strain they were looking for was found in a cantaloupe in a market next to the lab that had agreed to assist the Oxford lab to produce the penicillin in the first place.

By around the end of 1941, a mold nutrition expert named Andrew J. Moyer was able to multiply the production of penicillin by about 10 times and by 1943, penicillin was finally approved by public use. In the beginning, doses of penicillin were very expensive, but as it became more common, the doses went down in price significantly finally settling around fifty cents per dose in the mid 1940’s.

Unfortunately, there are some people that have been found to have an allergic reaction to penicillin and cannot be treated with it in the case of bacterial infection like other people can. If you are allergic to penicillin, it is possible that your child may also be allergic, so if your girlfriend or wife is expecting, you should notify your spouse’s doctor of your allergy.

How To Keep Mold From Calling Your Fridge Home

Finding mold growing in your refrigerator is something that we cannot usually avoid, because mold exists everywhere we are and it grows on dead organic materials, just like what we keep in our refrigerator. There are ways, however, to reduce the amount of mold that will grow in your refrigerator.

You should take inventory of your refrigerator and anything that is outdated beyond use should be thrown away because if mold is not growing on it now, it will eventually. The sooner that you forget an outdated item is in your refrigerator, the sooner mold will begin to grow inside it and spread to other items nearby. The spread of mold in this way is especially true of fruits and vegetables that are often stored in a bin on top of each other. One infected item can affect the whole bin and make it inedible. It is best to go through these items as often as possible to make sure anything contaminated is removed.

When you bring fruits and vegetables home from the grocery store, we often have them in the plastic bags that we used in the produce section to pack them in. You should probably remove these items from the bags in order to reduce the amount of condensation they are exposed to. Condensation will build up inside the bag as water evaporates and mold will begin to grow.

Cleaning the refrigerator regularly is also essential to slow the growth of mold. Everything in the refrigerator should be washed thoroughly and since no surface inside it should be porous, using chlorine bleach to wash the inside should be fine to assist in removing any mold that has begun to grow. Whatever you choose to clean your refrigerator with, please do not mix household chemicals when cleaning your home. The results can be harmful or even deadly if you mix the wrong two, such as bleach and ammonia.

Before you really start cleaning it out, take the light bulb out of your fridge because they are not made to be left on for more than a few minutes and will possibly burn out if you leave the refrigerator door open for too long.

After you are done washing the inside of the refrigerator, take a few minutes and go through everything as mentioned earlier and throw out anything that you think is too old. Washing down the outside of the refrigerator is also a good idea.

Mold Dogs are Unprofessional

When you go to hire a professional company that deals with mold contaminations, there are a few different things that you need to look for to determine whether or not the company is actually professional or not. Do they use the most modern methods of mold detection and cleaning? Do they wear protective gear? What kind of gear do they wear? Body suits? Respirators? And this is perhaps one of the most important questions of all: do they use animals to detect the presence of mold in your home?

The simple fact is that companies that use dogs to detect mold in a home or business are not professionals. They just are not. The practice of using dogs to detect mold in a home or in another building is inhumane and cruel to the animal, simply because of the knowledge that pets are just as susceptible to health damage due to mold as human beings are. A “mold dog” cannot detect whether or not the mold that exists in your home is toxic, what kind of mold it is, or in what quantity that it may exist. This is what mold laboratories and testing kits are for. All a mold dog can do is tell you if mold exists on the premises or not.

It can cost thousands of dollars for a company to have a dog trained to detect mold, but even after the dog is trained, it is almost surely money thrown down the drain. Dogs are trained to actively inhale mold spores, which is something that we as human beings are repeatedly told NEVER to do. We are told to wear respirators to filter these harmful spores out of the air that we breathe when we are dealing with mold. The animal is not aware that these spores can harm them at all. Dogs can develop severe skin, eye, and sinus infections and not to mention lung infections and even pneumonia. Unfortunately, the dog has no way of telling us that something is wrong with it. It knows, but cannot communicate this to us.

There are many other more modern, more professional ways to deal with the task of detecting mold on a piece of property. Any company that uses mold to detect dogs is not one that you want to deal with. Mold dog websites often have pictures of completely healthy animals and they will remain healthy for a while, but the typical cause of death is due to mold-related health complications.
