A
This organism causes meningitis with petechiae because endotoxins damage blood vessels.
Neisseria meningitidis
This nervous system defense makes many CNS infections difficult to treat with antibiotics.
Blood-brain barrier
This protozoan enters through the nasal passages after freshwater exposure and rapidly destroys brain tissue.
Naegleria
This disease causes flaccid paralysis because acetylcholine release is blocked.
Botulism
These CNS phagocytes act similarly to macrophages.
Microglial cells
This viral illness is usually milder than bacterial meningitis and is diagnosed partly by absence of bacteria in CSF.
Viral meningitis
This vector-borne encephalitis causes severe disease in fewer than 1% of infected patients.
West Nile virus
This organism can grow at refrigerator temperatures and is dangerous during pregnancy.
Listeria monocytogenes
This disease may produce elephantiasis due to lymphatic obstruction.
Filariasis
These HIV receptors/coreceptors are targeted by gp120 during viral entry.
CD4 and CCR5/CXCR4
This mosquito stage of Plasmodium is injected first into humans.
Sporozoite
This disease may follow inadequately treated strep throat because antibodies cross-react with heart tissue.
Rheumatic fever
This structure sweeps trapped microbes upward from the respiratory tract.
Mucociliary escalator
This bacterial throat disease forms a pseudomembrane that bleeds if removed.
Diphtheria
This complication of influenza often occurs because damaged cilia allow bacterial invasion.
Pneumonia
This organism survives inside phagolysosomes and is linked to contaminated cooling towers.
Legionella pneumophila
This disease is associated with beta-hemolytic Streptococcus pyogenes and erythrogenic toxins.
Scarlet fever
This zoonotic respiratory disease spreads through aerosolized rodent waste and can cause pulmonary edema.
Hantavirus pulmonary syndrome
This type of influenza antigenic variation occurs when two viruses exchange genome segments.
Antigenic shift
This lower respiratory infection commonly causes consolidation and pleurisy.
Lobar pneumonia
This disease can be vertically transmitted from vaginal flora during childbirth.
Group B Streptococcal disease
This pneumonia organism lacks a cell wall and is common among college students.
Mycoplasma pneumoniae
This respiratory defense contains lysozyme and traps inhaled organisms before they reach the lungs.
Mucus
This bacterial pharyngitis may progress to Lemierre syndrome if bacteria enter the bloodstream.
Fusobacterium necrophorum infection
This disease often causes cyclic fevers due to synchronized rupture of infected RBCs.
