There is a possibility of a crackling under the skin when compressed slightly, and an inability to contract the muscle in the affected area. Pathogenicity. The Clostridial bacteria most commonly infect a pre-existing wound either from injury or surgery. Because it is an anaerobic bacterium it will thrive in an environment with devitalized tissue. Once the infection has occurred the bacteria produce a toxic gas that kills muscle, providing an even more anaerobic area, which explains such rapid spread in the body.
* Once blind it cannot be reversed. | Mouth, Throat and Nose | * Smoking causes black staining on teeth that may not go away for a long period of time. * Smoking causes Leukoplaka, this is a lesion in the mouth that can lead to cancer * smoking increases tooth decay, tooth loss and bad breath (Halitosis). * Smoking can also impair taste and sense of smell. * Smoking can cause Melanosis, this
Any water containing human waste is considered black water. Greywater is important since that earth has become low on certain fossil fuels. Grey water has more than just H2O but less of the harmful stuff that makes you sick. Today, this waste water is referred to as greywater. Greywater is all the waste water generated in your home, excluding water going down the toilet.
 Should only be used if heat treatment is impractical or harmful to the material.  STERILANT: chemical disinfectant that kills bact. spores ( usually takes long exposure time) called ‘High Level Disinfection”.  Outcome is affected by the  Presence of organic matter (Bioburden)  Type & Level of microbial contamination  Disinfection concentration  Exposure time  Physical structure of the object  Temperature & pH of the process  ANTISEPTICS :  Chemicals used to kill microbes on skin or living tissue.  Must have effective antimicrobial activity.
Another disease soldiers caught during World War 1 is dysentery. Dysentery is an infection of the intestines marked by severe diarrhoea, caused by poor water supply, water cleanliness and no proper toilets for the soldiers to use. Dirty drinking water caused a lot of problems during World War 1, mainly because it contains all sorts of illnesses and diseases, which once you have in your system, cause you to get ill. Cholera was cause by dirty water, causing sickness, diarrhoea and even death it if was left untreated for long enough. Trench mouth was also common during World War 1. This is where you get an infection of the mouth, caused by poor oral hygiene and lack of important vitamins, due to a poor diet, smoking, tooth or mouth infections and stress.
Toxin produced is responsible for the infection Staphylococcal toxins can also act as superantigens Cleaning and removal of dirt reduces rates of infection Antibiotics, resistant strains 2. Streptococcus pyogenes: Group A Strep “Flesh-eating” bacteria Necrotizing fascitis. Bacteria multiply in dead tissue, producing toxin which kills tissue, muscle Superantigens Antibiotics are of little value in killing bacteria as the circulatory system which would carry the drugs, does not function in the dead tissue, sometimes amputation may be needed. 3. Pseudomonas aeruginosa: is the prime cause of life threatening burn infections.
Introduction Soaps and cleaning solutions have the potential to be valuable tools the pest management. Soaps used as insecticides control targeted pests with fewer potential adverse effects to the user, beneficial insects and the environment as compared with traditional pesticides (Pundt 2011). To be most effective, it's important to understand how insecticidal soaps "work," to know their mode of action. Insecticidal soaps work only on direct contact with the pests. The most common soaps are made of the potassium salts of fatty acids.
(Chaudry, 2011, para. 5) Botulism also impairs the neuromuscular junctions. The release of the Botulinum toxin will eventually lead to respiratory and musculoskeletal paralysis. (Chaudry, 2011, para. 5) Botulism can also be contracted through an open wound.
The common way of treating a virus is through immunization as anti-biotics will not be effective against viral infections. The virus infection can cause things like the Influenza, common cold, stomach flu, pneumonia, blood born infections, ear infections and HIV/AIDS. Fungi- live in the air, water, soil and on plants and they can live in the
Onychatrophia is often confused with anonychia, which is another nail disease that is caused by congenital disorders. In this case, the nail does not grow to its full length. Onychatrophia is considered to be one of the more severe, yet common, cases of nail infections because the nail eventually falls off from the finger or the toe. You will know that you have the disease if your nails grow slowly. The edge of the nails cannot be seen clearly; it seems as though the end of the nail has grown into the flesh of the finger or the toe.
