Having a Penicillium mold allergy doesn't mean that you're allergic to the antibiotic penicillin. While penicillin was indeed originally developed from Penicillium mold, people with this specific mold allergy are not at any more risk of developing an allergy to this class of antibiotics than anyone else with a history of allergies.
Modern-day penicillin antibiotics are produced synthetically and are not contaminated with mold particles. It is possible, however, to have related food allergies if you have a mold allergy. Penicillium can be found in certain aged and blue-veined cheeses, such as Roquefort and Camembert. There have been reports of food allergy reactions in Penicillium -allergic people who eat these cheeses and other foods with this mold.
If you have an allergic reaction to mushrooms, it's more likely that it's from the mushrooms themselves, but symptoms of oral allergy syndrome have been reported in people with mold allergies who have eaten raw mushrooms. Yeast is another potential food allergen if you have a mold allergy. You may be wondering how a mold allergy can be related to a mushroom or yeast allergy.
The answer is explained by a phenomenon called cross-reactivity. Cross-reactivity means that there are similar proteins shared between certain foods and certain molds. So if you're allergic to molds, you may very well react to foods like mushrooms that contain a similar protein. There is also ample scientific evidence suggesting cross-reactivity between different pollens and raw fruits and vegetables. Likewise, an allergy to latex can predispose people to certain food allergies mostly fruits and nuts.
The big picture here is that while a mold allergy may lead to a food allergy such as yeast or mushrooms, it doesn't mean you'll develop allergies to medications like penicillin. That being said, a history of allergies puts you at a higher risk of developing other allergies , so it is possible for you to have both an allergy to certain molds and a penicillin allergy, but the two are not interconnected—it's simply a coincidence.

Updated June 29, Mayo Clinic. Squibb solved this problem by introducing glyceryl monoricinolate as an anti-foaming agent. Submerged fermentation also required the design of new cooling systems for the vats and new mixing technology to stir the penicillin mash efficiently.
Lilly was particularly successful in making the mold synthesize new types of penicillin by feeding precursors of different structure. Once the fermentation was complete, recovery was also difficult; as much as two-thirds of the penicillin present could be lost during purification because of its instability and heat sensitivity. Extraction was done at low temperatures.
Methods of freeze-drying under vacuum eventually gave the best results in purifying the penicillin to a stable, sterile, and usable final form. The steps of fermentation, recovery and purification and packaging quickly yielded to the cooperative efforts of the chemical scientists and engineers working on pilot production of penicillin.
On March 1, , Pfizer opened the first commercial plant for large-scale production of penicillin by submerged culture in Brooklyn, New York. Meanwhile, clinical studies in the military and civilian sectors were confirming the therapeutic promise of penicillin. The drug was shown to be effective in the treatment of a wide variety of infections, including streptococcal, staphylococcal and gonococcal infections. The United States Army established the value of penicillin in the treatment of surgical and wound infections.
Clinical studies also demonstrated its effectiveness against syphilis, and by , it was the primary treatment for this disease in the armed forces of Britain and the United States. The increasingly obvious value of penicillin in the war effort led the War Production Board WPB in to take responsibility for increased production of the drug.
The WPB investigated more than companies before selecting 21 to participate in a penicillin program under the direction of Albert Elder; in addition to Lederle, Merck, Pfizer and Squibb, Abbott Laboratories which had also been among the major producers of clinical supplies of penicillin to mid was one of the first companies to begin large-scale production.
These firms received top priority on construction materials and other supplies necessary to meet the production goals. The WPB controlled the disposition of all of the penicillin produced. One of the major goals was to have an adequate supply of the drug on hand for the proposed D-Day invasion of Europe. Feelings of wartime patriotism greatly stimulated work on penicillin in the United Kingdom and the United States.
For example, Albert Elder wrote to manufacturers in "You are urged to impress upon every worker in your plant that penicillin produced today will be saving the life of someone in a few days or curing the disease of someone now incapacitated. Put up slogans in your plant! Place notices in pay envelopes! Create an enthusiasm for the job down to the lowest worker in your plant. As publicity concerning this new "miracle drug" began to reach the public, the demand for penicillin increased.
But supplies at first were limited, and priority was given to military use. Chester Keefer of Boston, Chairman of the National Research Council's Committee on Chemotherapy, had the unenviable task of rationing supplies of the drug for civilian use. Keefer had to restrict the use of the drug to cases where other methods of treatment had failed.
Part of his job was also to collect detailed clinical information about the use of the drug so that a fuller understanding of its potential and limitations could be developed. Not surprisingly, Keefer was besieged with pleas for penicillin. A newspaper account in the New York Herald Tribune for October 17, , stated: "Many laymen - husbands, wives, parents, brothers, sisters, friends - beg Dr.
Keefer for penicillin. In every case the petitioner is told to arrange that a full dossier on the patient's condition be sent by the doctor in charge. When this is received, the decision is made on a medical, not an emotional basis. Fortunately, penicillin production began to increase dramatically by early Production of the drug in the United States jumped from 21 billion units in , to 1, billion units in , to more than 6.
The American government was eventually able to remove all restrictions on its availability, and as of March 15, , penicillin was distributed through the usual channels and was available to the consumer in his or her corner pharmacy. By , the annual production of penicillin in the United States was , billion units, and the price had dropped from twenty dollars per , units in to less than ten cents.
Most British companies moved over to the deep tank fermentation production of penicillin, pioneered in the United States, after the end of the war to meet civilian needs. In the United Kingdom, penicillin first went on sale to the general public, as a prescription only drug, on June 1, In Britain, Chain and Abraham continued to work on the structure of the penicillin molecule, aided by the X-ray crystallographic work of Dorothy Hodgkin, also at Oxford. The unique feature of the structure, which was finally established in , is the four-membered highly labile beta-lactam ring, fused to a thiazolidine ring.
The co-operative efforts of American chemists, chemical engineers, microbiologists, mycologists, government agencies, and chemical and pharmaceutical manufacturers were equal to the challenge posed by Howard Florey and Norman Heatley in As Florey observed in , "too high a tribute cannot be paid to the enterprise and energy with which the American manufacturing firms tackled the large-scale production of the drug. Had it not been for their efforts there would certainly not have been sufficient penicillin by D-Day in Normandy in to treat all severe casualties, both British and American.
The plaque commemorating the event reads:. In , at St. Mary's Hospital, London, Alexander Fleming discovered penicillin. This discovery led to the introduction of antibiotics that greatly reduced the number of deaths from infection. Howard W. Florey, at the University of Oxford working with Ernst B. Chain, Norman G. Heatley and Edward P. Abraham, successfully took penicillin from the laboratory to the clinic as a medical treatment in The discovery and development of penicillin was a milestone in twentieth century pharmaceutical chemistry.
Since the release of penicillin, bacterial resistance to the drug has flourished, and the number of drug-resistant bugs can grow as long as the drug is used, according to the Centers for Disease Control and Prevention. By identifying subtle differences in the mold strains used to make penicillin, Barraclough told CNN that his team hopes to come up with new ways to "improve our use or the design of antibiotics for combating bacteria.
