Disentery, Shigella and Amoebae

Molds are in fact everywhere. They are a part of nature that we simply cannot get away from. However, molds are most active in places where they have cold, dampness and a source of food. This makes cold storage facilities for fruit and vegetables ideal places for molds to thrive.age-1238304_1920

Fruit and vegetables may sit in cold storage facilities for weeks, sometimes months. The air inside is stale, high in carbon dioxide which is also good for molds. Mold forms mostly on the walls and the ceiling of cold stores where they form spores. Spores are released in waves into the air and float down to settle upon the skin of Fruits and vegetables.

As the spores develop they produce tiny microscopic like structures that penetrate under the skin of the host and begin to soak up nutrients for digestion. If left long enough, these molds cells will connect until they take on the appearance that we are all familiar with, a green-grey furry coating.

Molds can seriously deplete the nutrient value of the host, soaking up vitamins and all kinds of phytonutrients which we believe we are getting when we buy fresh vegetable or fruit produce. What is more, because the produce is picked unripe, mold actually has an advantage over the produce because the plant has not fully developed its protection systems against mold and other microorganisms. The mold, actually reduces the acidity of the unripe produce.

Although most molds do not directly cause us disease, if we are healthy, it does indirectly help other microorganisms to gain an advantage over us by reducing the level of vital compounds in the food that we need to keep the body fit and disease resistant.

Now some companies are combating this phenomena by producing nutritional food supplements that have been made out of fully ripe and fresh vegetables. Such supplements undergo special procedure to separate a high percentage of phytonutrients from other parts of the plant structure such as sugars, carbohydrates and cellulose pulp. One such Company is Juice Plus. Their product is made from a wide variety of fruits and vegetables, thirty in fact. This gives the body a large compliment of nutrients that substitute what is lost in normal nutrition due to poor storage conditions. In fact, even if we buy farm fresh produce we would be hard pressed to eat such a large variety of fruit and vegetables every day so in this sense we are supplying the body with as much as we can for it to work with.

Most of us in the western world think of dysentery or “Shigella” as a disease of the summer months. Have you ever thought why? Firstly, is it true? Is dysentery a disease of the summer months?

Ok, now I’m going to confuse you a little more because the answer is yes and no. No because dysentery is not only a disease of the summer months and yes because it is mostly proliferated throughout the western world during the summer months, but why?

Dysentery is a disease that is spread via contaminated food and water. A lot of our summer produce is picked in warmer regions of the world where the water sourses osed to irrigate and to wash produce before packing may not be of the best quality and may contain many contaminants. In addition, workers who pick and pack produce may be carriers of certain types of dysentery causing bacteria.

Another major cause of dysentery during summer months for westerner’s is travelling to warmer climates. Whereas locals in many areas of the world may have developed immunities to many bacterial and protozoic species, all of these may be new for us. By being tempted to eat as the locals do we are often exposing ourselves to sources of food and water contamination.

Dysentery is caused by several major causes lets have a look at a couple of them.

Bacterial Dysentery. Bacterial dysentery is caused primarily by the bacterium Shigella dysenteriae. The disease it causes is called shigellosis. This bacterium is a gram negative, non motile, rod shaped, non spore forming facultative anaerobic species that produces a toxin called shiga toxin which is what causes the reaction which we know as dysentery.

Allow me to translate that mouthful of scientific jargon for you. Firstly Gram testing is a form of bacterial staining devised by a man called Mr. Gram which adheres to proteinous outer shells but not to fatty shells. As the vast majority of gram negative bacteria have a Lipopolysaccharide outer shell the dye will not stick, therefore the bacteria are classified as gram negative. Non motile means that they have no mechanism by which they can propel themselves within the medium they are in. Non spore forming means that the bacterium does not have the capability of reducing it’s structural size to permit it to survive periods when conditions are not suitable for bacterial growth, hibernating in short. Facultative anaerobic means that it can live in an oxygen rich environment or in one which is void of oxygen. It is usually when in the anaerobic phase that facultative bacteria will produce their toxins.

The symptoms of dysentery are high fever, vomiting, diarrhea, severe dehydration. Shega toxin is a potentially deadly toxin. Patients with dysentery may experience projectile diarrhoea and projectile vomiting simmultaneously. This is a very unpleasant condition which I have experienced personally. With this disease fluid intake is vital even if that means via infusion and a strict hygiene regeme is vital to rule out the possibility of re infection. Recovery usually takes anything between one to two weeks but in many areas of the world high mortality is common due to improper conditions with which to treat this condition. Mortality rate is particularly high in children and the elderly.

Amoebic Dysentery. This form of dysentery is also spread by the ingestion of contaminated food and water. It is caused by a cyst forming amoebic species. The disease is called intestinal amoebiasis.

This disease is most common in the developing world but not only. One case was reported in St. Petersburg which is quite close to the artic circle. Both bacterial and Ameobic Dysentery are prevelant in developing countries and often get confused. Most cases of travellers dysentary are in fact bacterial or viral in origin. Amoebic dysentery is a parasitical disorder and will not be effected by antibiotics. This form of dysentery may cause infection and enlargening of the liver and blood in stools. Other symptoms remain very much the same as in bacterial dysentery. Metronidazole is the preferred treatment for Amoebic Dysentaty.

Note. Not all species of amoebae are cyst forming.
