|
Pathogen that most commonly produces lung abscesses and is a common secondary invader in the lung in patients with influenza
|
Staphylococcus aureus
|
|
|
Pathogen that is contracted when the newborn passes through the birth canal. It produces a pneumonia characterized an abrupt onset of tachypnea, staccato cough, wheezing, hyperaeration, eosinophilia, and conspicuous lack of fever. It is often associated with conjuctivities
|
Chlamydia trachomatis
|
|
|
Coronavirus initially transmitted by civets in China and then by human contact. It is associated with severe pneuomonia often leading to death
|
SARS virus
|
|
|
Childhood pathogen that may produce a pneumonia associated with Warthin-Finkeldey multinucleated giant cells. Staph aureus may complicate the pneumonia
|
Rubeola
|
|
|
water loving pathogen that is commonly seen in men over 40 years old who are smokers and in organ transplant patients. It produces confluent bronchopneymonia with high fever, non-productive cough, hemoptysis, and other systemic signs and symptoms. It commonly produces hyponatremia related to development of interstitial nephritis leading to hyporeninemic hypoaldosteronism. the pathogen is best visualized with direct immunofluorescence or a silver stain:
|
Legionella pneumophila
interstitial nephrtitis damages JG apparatus causing a type IV renal tubular acidosis |
|
|
respiratory pathogen with significant mortality in those over 55 and who have underlying renal, cardiac, and lung problems. It produces a severe exudative pneumonia with a propensity for secondary bacterial invasion. There is an association with Reye's syndrome in children that take aspirin
|
Influenza
S. aureus is the usual bacteria that may superimpose on the influenza pneumonia. Minor mutations in hemagglutinin/neuraminidase do not require a new vaccine while a major mutation in hemagglutinin/neuraminidase (antigen shift) does require a new vaccine against the A virus |
|
|
respiratory pathogen that is transmitted without a vector, unlike other pathogens in its family group. It is primarily transmitted by inhalation by individuals who have an association with the birthing process in sheep, cows, and goats or in those who work with milk industry. It is particularly common in workers who shovel feces in sheep.
|
Coxiella burnetii
it produces a atypical pneumonia myocarditis granulomatous hepatitis |
|
|
respiratory pathogen is transmitted by direct hand to hand transfer of infected material and by respiratory droplet infection. Its main reservoir is school children. Development of a vaccine is highly unlikely
|
Rhinovirus
most common cause of common cold |
|
|
respiratory pathogen transmitted by droplet infection. It accounts for 10% of community acquired atypical pneumonia and a smaller percentage of cases of bronchitis. Cold agglutinins are not associated with this pathogen. There is no association with CAD.
|
Chlamydia pneumonia (TWAR)
|
|
|
pathogen that is commonly contracted in military stations and in crowded situations. It produces an interstitial pneumonia and is often associated with erythema multiforme and bullous myringtis. It responds well to erythromyocin
|
Mycoplasma pneumonia
|
|
|
Pathogen that is the second most common cause of acute exacerbation of chronic bronchitis and a common pathogen causing otitis media and sinusitis
|
Moraxella catarrhalis
|
|
|
Most common cause of death in patients with cystic fibrosis
|
Pseudomonas aeruginosa
Another pathogen that commonly causes death in Burkholderia cepacia |
|
|
Most common cause of pneumonia and bronchiolitis in infants
|
Respiratory syncytial virus
|
|
|
Most common cause of croup with inspiratory stridor. An anterior neck x-ray demonstrates a "steeple sign"
|
parainfluenza
obstruction is at the level of the trachea |
|
|
Most common cause of tension pneumothorax in children with CF
|
Staphylococcus aureus: organism produce tension pneumatocysts in the pleura
|
|
|
most common cause of inspiratory stridor in child whose lateral neck x-ray demonstrates the "thumbprint" sign due to swelling of the epiglottis. Its incidence has decreased owing to the use of a vaccine:
|
Hemophilus influenze
|
|
|
Most common cause of bronchopneumonia and lobar pneumonia in the general population:
|
Streptococcus pneumonia
|
|
|
pathogen that produces pseudomembranous that produces a toxin that inhibits elongation factor 2
|
Cornyebacterium diptheriae
EF-2 normally elongates proteins |
|
|
an executive in an office in NYC has a window air conditioner that is a favorite roost for pigeons. She and her secretary both develop lung disease. The causative agent:
|
Cryptococcus neoformans
pigeons carry Cryptococcus in the excreta. pigeons commonly live under bridges |
