symptomsThe signs and symptoms of tetanus may include:*Muscle spasms that begin in the jaw and neck*Inability to open the mouth (lockjaw)*Swallowing problems*Breathing difficulties*Painful convulsions (fits)*Abnormal heart rhythms.The extremely serious and potentially lethal complications of tetanus can include:*suffocation*respiratory failure*pneumonia*hypertension (high blood pressure)*hypotension (low blood pressure)*heart attack.

DiagnosisThe diagnosis is usually made by physical examination and taking the medical history, including information about immunisation. It is difficult to confirm a diagnosis through laboratory tests.Some wounds are more likely to encourage the growth of tetanus bacteria. Examples of these wounds are:*compound fractures (the broken bone pierces the skin)*burns*animal bites*any type of penetrating wound, such as from a rusty nail or rose thorns*wounds contaminated with soil, horse manure or foreign objects such as wood fragments.

This is what tetanus does to people horses and dogs.

DefintionMold: A furry growth of minute fungi occurring typically in moist warm conditions, especially on food or other organic matter.


symptomsThe most common symptoms include:*decreasing muscle strength and endurance*muscle and joint pain*breathing, swallowing or speaking difficulties*fatigue*increased sensitivity to cold or heat*breathing difficulty or sleep disturbance

Treatment for tetanus may include:antitoxin (called tetanus immunoglobulin) – to neutralise any tetanus toxin that is circulating and not yet attached to nerve tissuehospitalisationanti-convulsive medicationsantibioticslife support – for example, the person may be placed on an artificial respirator if they have severe breathing problemsvaccination – having tetanus does not make you immune, so you should be immunised.

Penicillin: Has been used for many years but it is a GABA antagonist and is associated with convulsions.Metronidazole: Has recently been discovered and is the best option for treating and preventing anaerobic bacterial diseases

Treatment:Because no cure for polio exists, the focus is on increasing comfort, speeding recovery and preventing complications. Supportive treatments include:Bed restPain relieversPortable ventilators to assist breathingModerate exercise (physical therapy) to prevent deformity and loss of muscle functionA nutritious diet

In 1884 Arthur Nicolaier produced tetanus in animals byinjecting them with samples of soil. In 1889, Dr. Shibasaburo Kitasatoisolated the organism from a human victim, showed that itproduced disease when injected into animals, and reportedthat the toxin could be neutralized by specific antibodies

Dr. Jonas Salk developed the first safe and effective polio vaccine in 1955.

Karl Landsteiner and Erwin Popper discovered poliovirus in 1908 by proving that it was not a bacterium that caused the paralysis, but a much smaller entity—a virus.

As well as his own contribution to health science, the Salk insititue continues to study major areas of science such as: molecular biology and genetics, neurosciences, and plant biology. Salk research provides new understanding and potential new therapies and treatments for a range of diseases—from cancer, AIDS and Alzheimer's disease, to cardiovascular disorders, anomalies of the brain and birth defects. Discoveries by plant biologists at the Salk pave the way to improving the quality and quantity of the world's food supply and to addressing pressing environmental problems, including global warming. This allows Dr. Salk's contibutions to modern medicine to continue.

the food is new

no changes

The food was kept in the kitchen in a corner where little light reaches them.

no changes

the bread is a little stale and the salimi is now a little more slimy,nothing for the apple

the bread is harder than a brick the salamii is shiny and slimy.

no changes

the bread is getting more stale the salimy is getting slimy, nothing for the apple

The bacterial colonies at 10 o'clock, 2 o'clock and 8 o'clock on this agar plate are producing antibiotics that inhibit encroachment by the mould which is growing out from the centre.

You can temporarily prevent mould by freezing the food that you want to keep or keep it in an air- tight container.

Processed foods contains additives and preservatives which prevent mould from growing. Fresh food doesn't contain any additives and will often go mouldy quicker.
