In the meantime they rob your system of nutrition, loading you down with their excretions and secretions these include Lice and Ringworm 1.3 Colonisation is when a bacterial strain invades a region of your body and starts to rapidly divide - it sets up a new colony Infection is similar but only usually used for opportunistic pathogenic bacteria - that is it does not usually refer to bacteria that normally inhabit us 1.4 Localised infection is restricted to a ceratin region of your body Systemic infection means that the infection is throughout your body. This usually means that the bacteria have been able to invade either your ciculatory system or the lymphatic system and spread 1.5 Some of the poor practises that may

When a virus enters the body, it enters some certain cells and takes over making the now host cell make the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common viruses is the common cold, which has no cure. Fungi Mould, yeast and mushrooms are all types of Fungi. Fungi live in the air, water, soil and on plants and they can live in the body, usually without causing illness. Some fungi have beneficial uses.
How Do Bacteria Affect Human Lives? Because bacteria are so versatile, adaptable, and very successful, it is no wonder that they occur in every habitat around the world; in the air, soil, water, inside your body, and on your skin [1]. Due to the wide variety of bacteria, some are harmless, and some are helpful. Harmful bacteria include those which cause tetanus and septicemia, whereas helpful bacteria include those that break down waste, and that help us in the food industry [2]. When many people think of bacteria, they also think of disease and infection.
Nucleus | The nucleus is the "Control Center" of the cell, which contains DNA (genetic information) in the form of genes, and also information for the formation of proteins.Information is carried on chromosomes, which are a form of DNA. | cytoplasm | The nucleus is the "Control Center" of the cell, which contains DNA (genetic information) in the form of genes, and also information for the formation of proteins.Information is carried on chromosomes, which are a form of DNA. | Golgi aparatus | The golgi apparatus of a cell is usually connected to an endoplasmic reticulum (ER) because it stores and then transports the proteins produced in the ER. | Mitochondria | "Mitochondria" is a plural term; which is appropriate as these are not found
Infection- This is an invasion by and multiplication of pathogenic, micro-organisms in a bodily part or tissue which could cause harm. Infections can be spread with ease, poor practice is the main reason for spread of infection. Examples of poor practices are not washing your hands regularly, hand washing should be done thoroughly with soap and water for at least 20 seconds, followed by hand-drying with a paper towel. Another example of poor practice is not covering your mouth when you cough or sneeze. You should always get vaccinated and always use safe methods of cooking and preparing food.
The Y. Pestis is contracted into the skin from when the fleas that have the disease in their bloodstream proceed to bite a human. The bacterium spreads to the lymph nodes in the armpit, groin, and neck. Here is where the bacteria cells multiply and cause swelling and tender, warm lumps called “buboes” to appear. You will also have a very high fever, fatigue, chills, headache, and muscle ache. In today’s age, this disease can be treated with antibiotics; however, this is still fatal in fifty to sixty percent of cases.
The amoebas are moved with pseudopods. The ciliates move with their cilia, and lastly the apicomplexan are parasites and don’t move around very well. Some microbiologists suggest that protists have many other kingdoms with in it, and that with some genetic sequencing and cellular components, protozoas evolved from several distinct precursors. 2. How are Algae and Protozoa the same?
Stratum corneum consists mainly of dead keratinocytes, hardened proteins (keratin) and lipids, forming a protective crust. Dead cells from stratum corneum continuously slough off and are replaced by new ones coming from below. The skin completely renews itself every 3 - 5 weeks. Most mild peels work by partly removing the stratum corneum and thus speeding up skin renewal. Another significant group of cell in the epidermis are melanocytes, the cells producing melanin, the pigment responsible for skin tone and color.
what is meant by “infection” and “colonisation”? Infection is something that is picked up through bad hygiene Colonisation is where an infection enters the body and grows. An infection is the colonisation of a host of organisms that enter the body and multiply. A systemic infection is one that affects the whole body, probably travelling in lymph or blood. This is in contrast to a local infection which only affects the area where the infection entered.
