What type of parasite is ingested in taeniasis?
Larval cyst
Gold standard for protection
Live vaccines
Cancer characteristics
Sustained proliferation which avoids apotosis, resistance to cell death. Induces angiogenesis.
Adenoma
Glandular epithelia with solid surface epithelia
African Trypanosomiasis
Parasite found in bodily fluids which occurs extracellularly.
Squamous metaplasia
Metaplasia of ducts and salivary pancreas in prescence of stones
Angiotrophic
Invasion of blood vessels by fungi which causes pulmonary haemhorrage and infarction
CD4 count 200-500
Increased risk of thrush, skin infection, TB
CD4 below 200
Increased risk of penumonia
CD4 below 100
Increased risk of toxoplasmosis
CD4 below 50
