extra disease stuff

life cycle of malaria - human side

1. sporozoites travel to liver and infect liver cells

2. sporozoites mature

3. sporozoites reproduce asexually to produce merozoites

4. merozoites released into blood and infect red blood cells

life cycle of malaria - mosquito side

1. gametocytes mature into gametes in mosquito gut

2. gametes fuse to form zygotes

3. zygotes develop into ookinetes

4. ookinetes form oocysts

5. sporozoites develop in oocyst

6. oocyst ruptures and releases sporozoites

7. sporozoites move to salivary glands

life cycle of chytridiomycosis

1. fungus produces zoospores and releases them into water

2. zoospores use flagella to swim toward amphibian and attach to skin

3. zoospores develop into thallus within skin

4. thallus grows into sporangium, reproducing in amphibian’s keratin containing skin cells

5. new zoospores produced and released from infected skin, allowing infection to spread

life cycle of phytophthora dieback

1. P.cinnamomi produces zoospores in wet soil

2. zoospores move through water towards plant roots

3. attach to root surface, encyst and germinate

4. pathogen grows into root tissue and forms hyphae

5. damages and kills root cells, particularly tissues involved in water and nutrient uptake

6. pathogen produces sporangium to release more swimming zoospores. can also form chlamydospores to stay dormant in dry soil
