Fungi :A Fungus is a spore producing organism and can live as a single celled yeast or as a larger multi-cellular mould. It will live by absorbing certain nutrients from any organic matter. Fungi include moulds, mildews, Mushrooms and yeast. The more common illnesses from fungi could be athlete’s foot, ringworm and thrush. Viruses: A virus needs a host cell to replicate.
Fungi Unlike bacteria and viruses, fungi are simple plant-like organisms which reproduce using spores. There are three types of fungal infections; ones which occur on the surface of the skin and hair; those which occur in the epidermis (such as ringworm and athlete's foot) and those which affect the deeper layers of skin – the dermis, subcutaneous tissue, muscle and fascia. Fungi may reach these layers as a result of penetrating wounds, or may be inhaled. Parasites Parasites differ from bacteria in that they need a living host to survive and reproduce, although not all parasites affect the host. Parasites can be acquired through contact with a contaminated surface, via infected water or food and through contact with contaminated bodily fluids such as blood, faecal matter and sexual contact.
I. Title: pGLO Transformation Lab II. Purpose; We want to be able to observe, comprehend and analyze genetic transformation as we genetically alter organisms. III. Hypothesis: If bacteria with + pGLO plasmids that are resistant to the antibiotic ampicillin and have the gene for GFP, colonies with survive and grow on the transformation plates that have LB/ amp.
P1: Explain how infections are caused by different pathogens: * Bacteria * Fungi * Protozoa * Parasites * Viruses Bacteria: Pathogens are microorganisms such as viruses or bacteria and these cause diseases in the body. Bacteria is a pathogen and are microscopic living cells that multiply at a rapid speed, once inside the body they spread toxins making the individual ill. Bacteria can cause diseases such as; * food poisoning * cholera * typhoid * whooping cough * gonorrhoea - a sexually transmitted disease Bacteria can travel in many things such as food, water or even through the air. For example if an individual is sitting next to someone that keeps on sneezing, the individual will eventually
There are different types of fungi for example mushrooms are a fungi and some cheeses have fungi in them, however fungi can also cause illnesses such as Candida, this is yeast that causes infection. Fungi are also responsible for skin problems such as, oral thrush, athlete’s foot and ringworm. A Parasite is an organism that lives inside another organism, which is known as the host. The host can be for eg, a human being, animal. The parasite is dependent on its host for survival, it has to be in the host to live, grow and multiply.
Some fungi have beneficial uses. For example, penicillin and yeast for baking. Thrush is a common fungal infection. Parasites are small organisms which depend can only live on a host. Plants, animals, humans, fish, birds and reptiles can all be host to parasites.
Like bacteria and viruses, some fungi can act as pathogens. Human fungal diseases can occur due to infection or fungal toxins. Symptoms of fungal diseases can be as common as itching, coughing, fever, wheezing, but they can also be as serious as meningitis or even death. Parasites are organisms that need other organism for their survival. They draw nourishment and other needs from their host organism.
Include surface description and color of pigment if present on the slants. Don’t confuse this with the color of the media which is light amber. Growth on agar slant (3pts) | Growth in broth tube (3pts) | Growth was up into agar slant with many smeared and bubblygrowth going into the linemade from the inoculating loop, thus covering it with growth. | Slightly turbid with few low lying particles at bottom of test tube (precipitation), pale yellow color. | | After mixing broth tube (3 pts)Still some turbidity, with few particles from bottom beingmoved throughout test tube, then settling again at bottomof tube, pale yellow color.
Crohn’s disease can affect any area of the gastrointestinal system from the mouth to the anus. Crohn’s disease appears to be caused by a dysfunctional inflammatory response in the gastrointestinal tract. Inflammation is the body’s natural way to heal by sending immune cells to the site of the injury or invader. Researchers
Because some bacteria can divide every twenty minutes, a new beneficial mutation can spread rapidly through prokaryotic populations in response to environmental changes. 2. Prokaryotic growth refers more to the multiplication of cells, rather than the increase in size. Various species of prokaryotes are adapted to various conditions. Refrigeration slows food spoilage because the lower temperature slows binary fission.
