Bacteria are important as decomposers in that they breakdown dead and decaying organic matter, releasing the minerals so they may be recycled. Bacteria are also involved in the production of a number of food products such as sauerkraut and yogurt. Bacteria in our intestines help the digestive process. Bacteria can be harmful causing a number of diseases such as strep throat and venereal diseases. They also spoil foods and attack crops.
There are various effects which bacteria can cause. Firstly, bacteria can cause various disorders in the body like Botulism, Tuberculosis and Gonorrhea Neisseria gonorrhoeae. Secondly, bacteria can result in food spoilage therefore, food industries are facing severe risks from bacterial attack. Thirdly, bacteria can cause food positing like Slamonella sp. In addition, bacteria can cause gastrointestinal infections because of ingestion of contaminated food.
Streptocaucus, and staphyllocaucus, are the 2 that come immediately to mind. Poliomyellitus and pneumococcus are another 2. I hope this helped, if so, please help me by clicking on a star next to RATE THIS ANSWER, so I will get credit for sincerely attempting an answer, thank you for this...*p
Bacteria are single cell organisms belonging to a category of life named prokaryotes. Bacteria were the earliest form of life on earth with their origin traceable to billions of years ago. There are thousands of different species of bacteria on earth and are found in four different shapes called bacillus, coccus, spirillium and vibrio.
Bacteria are both useful and harmful to other forms of life on earth. Extremely harmful bacteria make existence difficult for humans, animals and the environment by creating diseases and spreading infections.
Some of the harmful bacteria act as pathogens in creating and spreading diseases including tuberculosis, leprosy, cholera, pneumonia, syphilis, tetanus and typhoid fever to name a few. In plants, harmful bacteria cause wilts, fireblight, and leaf spot.
Harmful bacteria can create infection in a number of modes including through contact, air, water, food and through insect bearing microorganisms. The harmful bacteria can be destroyed by the use of antibiotics. It is also found useful to hamper their growth than destroying them altogether by the use of bacteriostatic antibiotics.
Bacteria are the largest class of creatures on earth and are comprised of single cells with no nucleus. They are the smallest free-living organisms in nature. Bacteria are responsible for 90% of all hospitalized infections in developing countries and cause the most serious infections humans are susceptible to.
Bacteria may yield to antibiotics, drugs that are used to cure many infections including, but not limited to, pink eye, Lyme disease, pneumonia, urinary infections, kidney infections, and strep throat. Bacteria are not responsible for viral infections. As such, they do not cause colds, influenza, AIDS, or other common infections.
