The parasite is dependent on its host for survival, it has to be in the host to live, grow and multiply. Although a parasite rarely kills the host, in some rare cases it can happen. It uses the host to gain strength, and the host becomes weak. It is responsible for causing various diseases such as, malaria, tapeworm, ringworm and roundworm. There are also parasites which live on the
Unit 4222-265 Causes and spread of Infection. outcome1: Understand the causes of infections 1:1 Identify the differences between bacteria, viruses, fungi and parasites. Infections are the result of the body’s inability to fight off microorganisms that cause disease or infection: Bacteria, viruses, fungi and parasites. Bacteria are organisms that are found almost everywhere. They are found naturally in humans, as well as plants and animals.
Causes and spread of infection Understand the causes of infection Outcome 1 Identify the differences between bacteria, viruses, fungi and parasites All 4 are different types of pathogens Bacteria is a single celled organism that multiply by themselves. They live within and on most living and non-living things. The majority of bacteria are harmless and beneficial to the human body but some can cause infectious diseases. A bacterium usually affects one part of the body and doesn’t spread across or through the body. Bacterial infections are normally treated with a course of antibiotics.
Parasites survive by feeding from its host. 1.2 Bacteria, common illnesses caused by bacteria are MRSA, Salmonella, Legionnaires disease, food poisoning, Pneumonia and Bronchitis. Viruses, common viruses are A common cold, measles, chicken pox and HIV. Fungi, common fungi are, Athletes foot, Ringworm and yeast infection. Parasites, common parasites are, Malaria and worms.
Fred Thompson Zoology 2/19/13 Heart Rate of Blackworms Experiment Introduction Blackworms are a species of worm that typically lives in shallow water habitats. They feed on microscopic organisms and organic matter. The scientific name for Blackworms is Lumbriculus variegatus and their classification is as follows: Kingdom: Animalia, Phylum: Annelida, Class: Clitellata, Subclass: Oligochaeta, Order Lumbriculida, Family Lumbriculidae and Genus: Lumbriculus (Svahn, 2009). An adult black worm can have anywhere from 130 segments to 250 segments. These segments are capable of forming a completely new black worm when detached from the host body, and in most Blackworms is the primary for of siring offspring.
Many bacteria are parasitic on external and internal body surfaces; some of these invade the inner tissues and cause disease. Most parasites are obligate; i.e., they are unable to
They average at about an inch long and have a hard brownish yellow exoskeleton. They are worm- like creatures that use their tough exoskeleton for burrowing into dirt and other terrains. It is said to be very difficult to determine the males from the females. Mealworms lay eggs that are white (http://insected.arizona.edu/mealinfo.htm). Mealworms in fact are not worms at all.
Causes and Spread of Infection 1. Understand the causes of Infection 1.1 Identify the differences between bacteria, viruses, fungi and parasites The differences between bacteria, viruses, fungi and parasites range. One of which is the fact that viruses and parasites depend upon a living host to survive, while bacteria and Fungi's don't always need to do so. Another difference is that Parasites are normally living creatures - ticks, fleas, worms - whilst bacteria, viruses and fungi are cells that have different cell coatings. 1.2 Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites The most common illnesses and infections that occur due to bacteria, viruses, fungi and parasites are Dioreah, Vomiting, Influenza, Nail infections, Tick bites, Colds, Skin Conditions, Digestive Problems ( Parasites - Worms ) and in some cases, Death.
Parasites are organisms that live within other organisms, called the host and it will often harm it. Parasites will reproduce at a very high rate and can also spread. There are three main types of parasitic diseases, these are protozoa which are a single celled organism and can only multiply within the host; helminths which is worm parasites and arthropods which include insects and spiders, the insects
Disease Research Short Paper [pic]Disease Topic : elephant disease. Etiology it is caused by parasitic worms invading the body's lymphatic system - the network of vessels carrying infection-fighting cells. The worm is spread by mosquitoes, who pass it on when they take blood from humans. The bacteria-containing worms lodge in the lymphatic system, producing millions of minute larvae which spread throughout the bloodstream. It is unclear whether the swelling, or lymphoedema, that occurs results from the obstruction of the lymphatic vessels or from the response of the body's immune system to the worms and the bacteria within them.
