This is significant in certain plants such as the Kudzu plant. Kudzu plants are also an invasive species that can cause damage throughout the ecosystem. The effect the Kudzu bug has on the environment is dependent on what it eats. Not only do they eat the soy bean plants, but they eat the stems and leaves of many different legumes . This can lead to extreme reductions in soybean growth.
Infection diseases happens when an unknown organism move into a person’s body and causes trauma such as bacteria, viruses, fungi and parasites. There are a lot of organisms in human body which normally harmless and helpful, but some may cause disease if the condition were alter. These organism stay in human 's’ body to help itself survive by reproduce and clonation. The infectious diseases can be easily passed from one to another. For instance, though the channel by bites from insects or animals.
It was a disease caused by the Variola virus both type major and minor. It was spread through means of contact such as airborne,bloodborne, and foodborne . Since it was a virus it hacked cells of the body and and reproduced in host cells giving the body terrible effects and symptoms such as permanent red scars/spots , vomiting, fever and colds. It can be tested and confirmed through the use of an electron microscope and through physical findings. .
The bacteria, Pseudomonas Aeruginosa, is gram- negative. This means it is does not have a violet stain. It is also considered a bacillus bacteria. Pseudomonas aeruginosa can be strictly found in aerosols, this means it is compressed in pressure and released into a fine spray. Research has been made and found that this bacterium harms a lot of plants, animals, but mainly humans in such case.
It bthe type of parasitic infection by tapeworm. This is one of common disease occur in most areas of the world. It also require two hosts, definitive host-carnivores and intermediate hosts- sheep and cattle. Humans are accidental hosts, because they are a dead end of this infection. Humans are infected by handling soil, dirt or animal hair that contains eggs of this tapeworm..In humans they are localized in the liver in most of the cases and in other organs of bodies such as spleen, brain heart and kidney.
Sputum contains a lot of bacteria, viruses, fungi and other pathogens. Respiratory infectious diseases, like influenza, tuberculosis, bronchitis, pneumonia, measles, pertussis, diphtheria and other pathogens, are spread through the sputum, very dangerous. Spitting there are many hazards, not only can cause health problems, in infectious disease multiple times, phlegm is a highly damaging route of transmission, inadvertently freely spit sputum are likely to have increased 10 people infected with the virus. First of all, spitting could lead to spread bacteria, into the air will harm to people. In our usual life, no spitting everywhere slogan, the reason is spitting is an extremely uncivilized unsanitary, spitting will make sputum bacteria spread easily, especially in public places, crowded place will make the spread of the virus.
Basidomycota are the spore producing body of fungus called Basidiocarps and composed of densely packed hyphae. They are best described as mushrooms. Basidiomycota is expressed in figure 2 and 3, easily recognized by the shape and spores coming from each point of the shape. They sexually reproduce by nuclear fusions within Basidia to make a diploid cell, which undergoes meiosis to form Basidiospores. This is reflected in figure 2 with those points I referred to before.
Pylori infection is on a steep decline in most of the western countries mainly due to the success of combination therapies and improve personal hygiene and community sanitation to prevent re-infection.The situation is not improving in many of the developing countries due to failure of treatment regimes and emergence of durg resistance. The infection in some cases leads to chronic superficial gastritis, chronic active gastritis, peptic ulcer disease and gastric adenocarcinoma.Humans are the only important reservoir of H.Pylori.  Children may acquire the organism from their parents (more often from the mother) or from other children. H.pylori is easily cultured from vomitus and gastroesophageal refluxate and is less easily cultured from stool. One of the most distinctive features of H.pylori is the genetic diversity between clinical isolates obtained from different patient populations.
The reactive individual papules surround a wheal, which always often have a central punctum. The histopathological changes seen in papular urticaria comprises of mild subepidermal edema, extravasation of erythrocytes, interstitial eosinophils, and exocytosis of lymphocytes. Papular urticaria is characteristically a clinically challenging condition, especially during spring and summer months. (9) Papular urticaria is the outcome of hypersensitivity (id reaction) to bites certain insect bites such as mosquitoes gnats, fleas, mites, and bedbugs. These pruritic papules and papulovesicles seen most commonly in children suffering from papular urticaria is symmetrically distributed.
QUESTION 4A EXPLAIN HOW DIFFERENT PROFESIONALS ARE EXPOSED TO BIOHAZARDS Biohazards present many professionals with complex health challenges. Most of these biohazards result from workplace exposure to organisms, or substances produced by organisms, that threaten human health. . Biological hazards are common in work places where workers come in contact with a broad range of diseases; work place like health care facilities, animal farms, game rangers and veterinarians are at greater risk for infections originating from the biohazards. Workers in these places are exposed to pathogens which may be spread by direct contact like droplet, airborne, faecal oral or blood borne transmission.
