By invading host cells
What makes fungi harder to kill compared to other pathogens?
Their thick cell wall
What is the main way that parasites cause illness in a host?
By feeding from the host
Which pathogen causes strep throat?
Streptococcus pyogenes
Which pathogen causes athlete's foot?

What are antigens?
Substances on the surface of cells, viruses, fungi, or bacteria
What are antibodies?
Y-shaped proteins made by the immune system
How does the immune system "remember" different pathogens?
By producing antibodies
Match the following pathogens with their type:
Hepatitis = Virus Escherichia coli = Bacteria Trichophyton rubrum = Fungus Enterobius vermicularis = Parasite
Match the following pathogens with the diseases they cause:
Hepatitis = Liver inflammation Staphylococcus aureus = Skin infections such as abscesses and cellulitis Streptococcus pyogenes = Strep throat, infection of throat and tonsils Trichophyton rubrum = Athlete's foot, an itchy foot rash
Match the following terms with their descriptions:
Antigen = Substances that trigger the body to fight them Antibody = Y - shaped proteins made by the immune system's B-cells when it detects antigens
Match the following antigens with the antibodies they fit with:
Poliovirus antigen = Antibody made for the poliovirus
Match the following pathogens with their descriptions:
Viruses = Not made of cells and use host cell to copy themselves Bacteria = Single-celled microorganisms that can cause infections by releasing toxins Fungi = Cells contain a nucleus and a thick cell wall, can cause disease by causing tissue death or taking nutrients from host cells Parasites = Organisms that live in or on a host and feed from them, causing weakness and illness
Match the following pathogens with the ways they cause disease:
Viruses = Invade host cells within the body and use the host cell to copy themselves, damaging or destroying the infected cells Bacteria = Cause disease by releasing toxins that make us sick or cause tissues to die Fungi = Cause disease by causing tissue death or by taking nutrients from host cells Parasites = Live in or on a host and feed from them, causing weakness and illness
Match the types of parasites with their descriptions:
Protozoa = Single-celled animals Helminths = Worms Ectoparasites = Insects
