Antibiotic resistant bacteria Microbes are all around us, they pretty much fill our whole world. They are in the air we breathe, the food we eat and even in our bodies. There is different types of microbes such as algae, fungi, protozoa, viruses and bacteria, they all have a different functions and structures. But the one microbe that is becoming a threat to us is bacteria because it is becoming antibiotic resistant, which means to us this is going to become a very big problem. Antibiotic resistant

infectious agent (pathogen) that causes this infectious disease? For example, the name of the bacteria, virus, or parasite? The nick names for the infectious agent that causes infectious disease names are; hepatitis Immunization, Havrix, VAQTA. Hepatitis is an acute infectious disease that can harm the liver. Several diseases of the liver, collectively known as hepatitis, are caused by viruses. The viruses involved, five of which have been reasonably well characterized, come from a wide range of

micro organisms found in milk vary considerably, and are dependent upon the specific conditions associated with a batch of milk. Bacteria, yeasts, moulds, and bacteriophages are commonly encountered. Other viruses and Protozoa are seldom observed in milk products, except as occasional contaminants. 3. Mention the pathogenic bacteria present in milk. The pathogenic bacteria that are present in milk are Listeria Monocytogenes, Yersinia Enterocolitica, Campylobacter Jejuni Mention and explain

Inflammatory bowel disease (IBD) is an inflammation of the digestive tract persisting for a long period of time. A typed of IBD would include chrons disease. 700,000 Americans are currently diagnosed with this disease. Chrons disease can affect different parts of the digestive tract and will likely advance far into the bowel tissue layers. To what causes chrons disease still remains a mystery. Scientist believe a person’s heredity and immune system are a factor in what causes this disease. If ones

The immune system is a network of cells that join together to combat the body against the attacks of a foreign invaders. These foreign invaders are mainly microbes such as parasites, fungi, and bacteria. Viruses are also considered foreign invaders to the body. The immune system’s job is to keep these foreign invaders out of the body. If some of them do come in the body, then it’s job is to kill them. A pathogen can be viewed as an infectious agent. It causes illness or disease to its host. It

Bacteria are among the first life forms present on Earth, and they can be found in almost every environment. They can be in the shape of rods, spirals, and spheres. The genera Bacillus is a rod shaped bacterium that often form chains and can be found in a wide range of habitats. [Tortora, G.] Bacillus can be endospore-forming aerobic or facultatively anaerobic. Their thick peptidoglycan layer in the cell wall encases their cell membrane, making them a gram-positive bacteria. The fact that Bacillus

Tetanus Tetanus is a potentially fatal disease that is rooted throughout all of human history. It is caused by a bacterium that can be contracted in a number of ways. While the human interaction and symptoms are not caused directly by the bacterium affecting human tissue as with normal bacterial infections. Instead, the symptoms common with the infection are caused by a reaction to a neurotoxin called Tetanospasmin (Wells). The symptoms of this toxin on the body are a result of the toxin binding
