Mode of transmission
Mode of transmission of Neisseria gonorrhoeae
sexually transmitted
mom to baby
salmonella enteritidis - typhoid & non-typhoid
typhoid:
fecal-oral
foodborne or waterborne
mechanical vector --> flies
non-typhoid:
fecal-oral (usually foodborne)
Which gram negative bacterias have vaccines available
nesseria meningitidis
salmonella enteritidis (typhoid)
bordetella pertussis
defining sx of neisseria meningitidis
hemorrhagic lesions - septicemic meningitis
defining sx of treponema pallidum
primary syphilis - chancre on genitals
secondary syphilis - systemic body rash
tertiary syphilis - gummas
Mode of transmission of Neisseria meningitidis
respiratory droplets
indirect contact
Mode of transmission of yersinia pestis
biological vector --> fleas (bubonic plague)
respiratory droplets (pneumonic plague)
which gram negative pathogens can be in normal microbiota and where
neisseria meningitidis- nasopharynx
escherichia coli- GI
defining sx of yersinia pestis
buboes (black hemorrhagic lymph nodes) - bubonic plague
defining sx of borrelia burgdorferi
bulls eye rash - lyme disease
Mode of transmission of escherichia coli
endogenous
fecal-oral
foodborne or waterborne
Mode of transmission of bordatella pertussis
respiratory droplets ( highly contageous )
which genera of gram negative pathogens are intracellular?
salmonella enteritidis (non-typhoid & typhoid)
shigella
legionella pneumophilia
chlamydia
rickettsia rickettsii
treponema pallidum
defining sx of bordetella pertussis
spasmatic cough - whooping cough
defining sx of vibrio cholerae
rice water stool- cholera
Mode of transmission of proteus vulgaris/mirabilis
endogenous
iatrogenic
Mode of transmission of Legionella pneumophilia
aerosols from water sources (showers, vents, jacuzzi)
what genera does urease help be virulent
proteus species
h.pylori
it breaks down urea to ammonia and co2 and water
this raises the ph allowing the bacteria to live (h.pylori)
it breaks down urea to ammonia and co2 and water and causes the normal salts to percipitate out of solution onto the bacteria, forming kidney stones (proteus)
defining sx of chlamydia trachomatis
corneal opasity - trachoma
which gram negative pathogens cause foodborne illnesses
escherichia coli
salmonella enteritidis
shigella
vibrio
campylobacter jejuni
Mode of transmission of shigella
fecal-oral
foodborne or waterborne
Mode of transmission of pseudomonas aeruginosa
direct/indirect contact
iatrogenic
which gram negative pathogens are common causes of meningitis
neisseria meningitidis
escherichia coli
defining sx of rickettsia rickettsii
rash on palms/soles - rocky mountain spotted fever
regarding chlamydia - what is the difference between elementary bodies and reticulate bodies
elementary bodies - inefective form. it goes into the host cell in this form and leaves in this form as well
reticulate bodies - replicative form. replicates inside the host cell here and turns into elementary body before leaving the host cell
