Introduction to Parasitology

What is a Parasite? parasite  A parasite is an animal that lives at the expense of its host. host  A host in an animal that the parasite lives in or has a symbiosis with.

Effect of the Parasite on the host  The presence of a parasite may injure the host in a number of ways: 1. Interference of vital processes 2. Destruction of host tissue 3. Produce toxins harmful to the host 4. Depriving host of nutrients

Effect of the Host on the Parasite  There are certain genetic and environmental conditions that parasites are effected by when they invade a host: 1. Genetic conditions  Sickle Cell Trait 2. Diet or Nutritional status of the host 3. Immune processes 4. Medications taken by host

Prevalence of Parasites Infections  Estimates of the prevalence of parasites based on World Health Organization ( WHO )and CDC.  Malaria: 500 million infected; 2.5 million deaths  African Sleeping Sickness: 100,000 new cases a year; 50,000 deaths  Hookworm: 1 billion infected  Elephantiasis: 128 million infected

World Distribution of Parasitic Diseases

Malaria Background  Scientific name for the parasite that causes malaria is Plasmodia falciparum  Attacks the red blood cells. intermediate host  The mosquito is an intermediate host of the parasite.

Malaria Life Cycle

Diagnosis and Symptoms  Diagnose malaria by taking blood sample and finding parasite  Symptoms of Malaria infection :  Headache  Muscle ache and pains  Nausea and vomiting  Intense fever and chills  Restlessness, disorientation and delirious

Epidemiology  Epidemiology is the study of the distribution and patterns of health-events.  The disease is found primarily in tropic climates.  Some cases have been found but in very small numbers in the United States.

Treatment  Medications and prevention methods that can be taken:  Use of bed nets in tropic climates  Quinine (medication)  DDT to kill mosquito  Use of DEET to keep mosquitos away (bug spray)  Use of Malaria Vaccine  Sickle Cell Trait  Sickle cell trait tends to have a resistance to the parasite that causes malaria.

Review Questions  What is parasitology?  What is epidemiology?  What are some symptoms associated with malaria?  What are some measure that can be taken to prevent malaria?
