• RMSF
  • Commonly seen in Southeast and Midwest
  • Different strains around the world
  • Antibodies notoriously tough to interpret
  • Should be covered by doxycycline but chloramphenicol is a potential option for refractory disease

• Miscellaneous
  • Leptospirosis is transmitted in rodent urine and is associated with liver disease, renal disease and conjunctival suffusion
  • Ricketsial pox is carried on rodents and seen in slums; associated with more mild illness
  • HSV 1 and 2 IgG and IgM should not be interpreted as chronic and acute as can wax and wane
  • New CSF biofire is a great tool to test for many infectious causes of meningitis but doesn't give titers
