Adaptations to Facilitate Transmission of Pathogens - Coggle Diagram
Adaptations to Facilitate Transmission of Pathogens
Soil borne
form endospores
resist dessication
stable in environment under range of condition
grow in mizosphere
fungi
Nemotodes
Airborne (on dust or respiratory secretions)
Influenza virus
Remain in air for long periods of time
Aero-tolerant
Pathogen causes coughing and sneezing -> transmission
Blood borne
Malaria
Facilitates growth + development
Takes advantage of altered features of red blood cells
Sexual (veneral)
Unprotected sexual activity
Clamydia
HIV/AIDS virus
Gonorrhoea
Vector borne
Vector not affected
Commensalism
Malaria
Zika Virus
Vector = reservoir
Digestive tract
Salivary glads
Surface protein on pathogen allows it to attach to vector tissue
Life cycle of pathogen synced to feeding of synced to feeding of host
Faeco-oral
E. Coli
Salmonella
Very stable in varied conditions
e.g. digestive system
Induces vomiting + dihorrea increasing transmission
Vertical (mother to child)
Transmission across the placenta
Uterine invasion
Having unprotected sex facilitates transmission
Rubella
Chicken pox virus
Water borne
Can colonise and proliferate in water
Environmental reservoir
Decomposing matter
Faecal material
Marine-borne
Halo tolerant
Tolerate high salinity
Modified outer structures
Flagella for mobility
Cholera
Giardia
