2nd Sheet Sickness Flashcards
(24 cards)
Strep throught
Streptococcus pyogenes
Which cause streptokinases and streptolysin exotoxin
Cause inflimmation tonsilitis otitis
Cause
Rapid diagnosis based on aggulitination tests
Definative test based on IGM bodies
EIA test
Complications :rheumatic fever and glomerneuphiritis(kidney infiction)
Scarlet fever
Corynebacterium dephteriae
Deptheria toxin cause by lysongenized c.diphtheria
Membrane contains fibrin and dead body cells forms and block air passage
Exotoxin inhibits protein synthesis cause kidney/heart and nerve damage
DTaP vaccine is used and diphtheria toxoid
Otitis media percentages
Shit n hit music super solid S.penumonia 35% Hameophilus influenzae 20-30% Moraxella cararhhalis 10-15% S.pyogenes 8-10% Staphylococcus aureus 1-2%
Common colds mostoften cause by
Rhinovirus30-50%
Coronavirus10-15%
Pertussis(whooping cough)
Lower respiratory system disease caused by bodetella pertussis
DTaP vaccine for prevention
3stages
Erythromycin is affective before the onset of paroxysmal stage (in cattarhal)
Cytotoxin=pertussis toxin
Tuberclousis
Mycobacterium tuberculosis acid fast
M.bovius not human to human
M.avium intracellular
Treatment Isoniazid ethambutol pyrazinamide rifampin
Testing tubercullin skin test if + then current or previous infection
To define X-ray or CT scan then acid fast staining of sputum
Pneumococcal pneumonia
Streptococcus pneomonia Encapsulated diplococci Symptoms Fill lung with fluids Rust colored sputum Macrolides/fluoroquinolone Prevent:vaccination made of s.pneumoniae
Haemphilus influenza pneumonia
Predisposing factors alcohol diabetes cancer bad nutrition Same as pneumonicoccal pneumonia effects Diagnosis by special culture Treatment:3rd generation cephalosporins
Mycoplasmal pneumonia
Mycoplasma pneumoniae
Pleomprphic and wallless
Walking pneumonia
Atypical pneumonia
Symptoms ; mild but lasts long -3weeks- low fever headache cough
Diagnoses by PCR and serological testing-
Treated by TETRACYCLINS
eleminate effects but not bacteria
Legionellosis
Legionella pneumophila
G-ve rod
In water found
Transmitted by inhaling aerosols not human-human
Symptoms
Potentially fatal pneumonia affect heavy smokers and drinkers 40.5 cough and high fever
Treatment Erythromycin
Chlamydia pneumonia
Obligate intracellular
Human-human
Symptoms
Mild symptoms such as mucoplasmal pneumonya
Diagnosis seriological tests
Treatment by tetracyclines as mycoplasmal pneumonia
Psittacosis
Chlamydia psittaci G-ve
Inhalation from dried birds feces (psittacine)
3-4 weeks headache chills and coughing (inflimmation of brain and liver 3-4 weeks)
A form of pneumonia
Treatment by:tetracyclines
Diagnosed by culture and PCR
Q-fever
Coxiella burnetti
Arthropods to cows to milk,feces and urine to human
By unpasteurized milk and inhaling areosoles
Viral pneumonia
There is a viral pneumonia in my chicken
Influenza measeles chickenpox
Respiratory syncytical virus
RSV 4.5k deaths annualy Cause cell fusion in culture Symptoms:pneumonia in infants Diagnosis:serological test Treatment:humanized monoclonal antibodies And Ribavirin
The influenza virus
H and N spikes H to connect N to release virus identefied by antigenic differences the H and N spikes Their protien coats are A B C And known for the antigenic shift such as the spanish flu 1918 Usuall treated by mivir:zansmivir/oseltamivir Or neuraminidase
Antigenic drifts
Mutations in genes HA or NA spikes
May involve one amino acid
Allows virus to avoid mucosal IgA antibodies
What are the deaths usually from in influenza infections
Usually from the secondary infection in influenza
Opportunisic fungi are able to grow in
Imunosupressed patients : transplant/cancer
AIDS patients
Histoplasmosis
Resembels tuberclosis (fungus) Histoplasma capsulatum Dimorphic fungus Yeas like in tissue Filamentous carrying reproductive condida in soil and artifical media Chemotherapy amphoteric B Itraconazole
Pneumocystis pneumonia
Pneumocytis jirovecci
Most suciptable are compromised immunity
100%lethal with no treatment
Treated by: Trimethoprim/Sulafmethoxazole
The best antifungal agent
Amphotericin B
Aspergillosis
Airborne for compromised immunity
By aspergillus famigatus
pulmonary infection by molds
Rhizopus/mucor
