HintAnswer
Opportunistic gram(-) rods ubiquitous in the environment, transient colonization of the human body transmitted by respiratory secretions and direct contact with fomites
Virulence factors: P1 adhesion (adherence to respiratory epithelial cells) -> inhibits ciliary action and protection; damage via toxic metabolic products

S/s sudden onset, high fever, thick bloody sputum (currant jelly) dx'd via microscopy and culture
HintAnswer
Most common bacterial causes of otitis media
VF: pili (adhesion to epithelial cells), capsule (anti-phagocytosis), biofilm, endotoxin and inflammation, tissue damage, extracellular enzymes and toxins (exotoxin A)
Tx of chlamydophilia pneumoniae

Found in infected persons or asymptomatic carriers. Virulence factors: capsule, type b = poly-ribitol-phosphate
Dx: not seen on gram stain; serodiagnosis by complement fixation test
VF: infects tracheobronchial epithelium; IMMOBILIZATION OF CILIA: Fha (filamentous hemagglutinin) + Ptx (pertussis toxin); KILLING OF CILIATED CELLS; tracheal cytotoxin
Prevention of streptococcus pneumoniae
Tx of pseudomonas aeruginosa
Tx of severe Haemophilus influenzae and Haemophilus influenzae type-b infections
Dx: not seen on gram stain; cx (eaton's media), serological tests (cold agglutinins & complement fixation tests)
Tx of Legionnaire's dz
Prevention of Legionnaire's dz
Found in nasopharynx & skin of infected persons or asymptomatic carriers causes strep throat, scarlet fever, & other disseminated dzs. Transmitted via resp droplets or direct conta
Virulence factors: polysaccharide capsule (antiphagocytic); IgA protease (colonization); pneumolysin (transmembrane-pore-forming toxin)
S/s fever, productive cough, wt loss, dyspnea, and cyanosis. Dx'd via microscopy, cx: blue-green colonies, fruity aroma (grapelike), fluorescence under UV light
Found in infected persons or asymptomatic carriers. Transmitted by respiratory droplets. Causes atypical pnemonia
Tx of otitis media caused by streptococcus pneumonia
Self-limiting dz with s/s of flu-like illness
Most common bacterial causes of epiglotitis
Transmitted by inhalation of contaminated aerosols (AC); risk group: no person to person transmission
Gram (+) rod single, paired or long serpentine chains ('box car chains'); spore-forming; polypeptide capsule. Ubiquitous/zoonotic.
Gram (-) coccobacilli, fastidious found in infected persons or asymptomatic carriers via respiratory droplets
Water organisms, gram (-), facultative intracellular pathogen. Ubiquitous in fresh H2O, free living or parasites of protozoa, biofilms in water sources
Dx: clinical, cx (charcoal-blood agar)
Corynebacterium diphtheriae prevention
Natural reservois is birds, transmitted through inhalation of dried secretions from infected birds, causes psittacosis
Tx of pneumonia caused by streptococcus pneumoniae
Most common bacterial cause of CAP

Lancet shaped, gram (+) diplococcus, catalase (-), a-hemolytic, bile-soluble, optochin-sensitive
Tx of sinusitis and otitis media caused by Haemophilus influenzae and Haemophilus influenzae type-b
VF: M-protein (adhesion & antiphagocytic), F-protein (adhesion), and hyaluronic acid capsule -> pharyngitis, sore throat, fever, erthyema, and exudates
developmt of reactive inflammatory focus -> tissue necrosis - damage d/t host response -> granuloma formation (Gohn) -> dissemination to local LNs -> poss dissemination to other ti
Virulence factors: Develomental cycle- EB (infectious, survives outside the host, non reproductive particles), RB (noninfectious, intracytoplasmic reproductive form)
s/s: fever (rapidly worsens), chills, malaise, HA, edema, massive enlargement of mediastinal LNs, respiratory distress, cyanosis, and shock. Dx: microscopy, cx
