Infectology Flashcards
Microorganismo causante de neumonías intersticiales
Virus
Principales microorganismos de los que se sospecha en infx pulmonar con granulomas
Hongos y tuberculosis
Vasos dilatados, infiltrado inflamatorio y plasma en pulmones
Fase congestiva
Exudado inflamatorio, con leucocitos y plasma en alvéolos.
Hepatización rojo
Pulmón gris por pus, alvéolos llenos de neutrófilos
Hepatización gris
Neutrophil infested and congestive lung vessels
Bronchopneumonia
Microorganism that leaves alveoli clean, linfocyte infiltrates in septums and dilated vessels.
Virus
Principales patógenos de neumonía hospitalaria
S. aureus, gram - y Pseudomonas
Fase donde hay abscesos pulmonares de tuberculo
Bacilífero
Tinciones para M. tuberculosis
Ziehl-Neelsen
auramina-rhodamina
Tipo de reacción inmune en M. tuberculosis
Reacción tipo 4 (misma que vs hongos)
Calcificación en ganglios y pulmones en tuberculosis
Complejo de Gohn
Solo en el ganglio se llama foco
Necrosis central, linfocitos alrededor y histoiocitos epiteloides.
Granuloma
Combinación de hemorragia con parénquima hepática, apariencia de nuez moscada
Hepatitis aguda
Puentes necro inflamatorios de porta a vena hepática, terminan reemplazándose por fibrosis
Hepatitis aguda
Eosinophilic intracytoplasmic inclusions shown, often in rabbies.
Negri Bodies
Complement deficiencies lead to infections by
Encapsulated bacteria (S. pneumoniae and Neisseria spp.)
Pathogens causing hospital-acquired pneumonia
Klebsiella, Serratia, E. coli, Pseudomonas, S. aureus
Pathogens causing health care-acquired pneumonia
S. aureus, P. aeruginosa, S. pneumoniae
Pathogens that cause chronic pneumonia
Nocardia, actinomyces, mycobacteria, histoplasma, coccidioides, blastomyces
Pathogens causing necrotizing pneumonia and lung abscesses
S. aureus, S. pyogenes, Klebsiella
Most common cause of community acquired pneumonia, vaccines with capsular polysacc.
S. pneumoniae
Most common bacterial cause of acute exacerbations of COPD, it causes meningitis.
H. influenzae
Pathogen that will cause pneumonia in the elderly, complicate COPD and otitis media in children.
Moraxella catarrhalis
It causes second bacterial pneumonia after viral respiratory illnesses.
Hospital-acquired pneumonia
S. aureus
Common cause of hospital-acquired pneumonias, cystic fibrosis and immunocompromised patients.
P. aeruginosa
It causes local epidemics and pneumonia. Schools, military camps and prisons.
Mycoplasma pneumonia
Patchy involvement in lungs is known as
Lobar consolidation
Lobar pneumonia stage 1: congestion Intra-alveolar edema, fluid with neutrophils and bacteria
