Card Set Information
What are the 3 effects of infectious endocarditis?
- Bacteria can initiate infectious endocarditis
- And stimulate the immune system
- The mature vegetation formed during the infection can detach from an infected heart valve and become an embolus that can then lodge in some distal organ.
what are the 2 most common causes of infectious endocarditis?
Strep viridans and staph aureus
What are the different types of plague?
: seen in wild rodents and the primary reservoir of the organism
: see in cities, more infectious form because there are more potential hosts in the city than in the wild.
Symptoms of tularemia: transmission through arthropod bite
swollen lymph glands
inhalation tularemia symptoms:
swollen lymph nodes
pain under the breastbone
What decides how tularemia will be present?
The inoculation site, the transmission,how far into the body the pathogen is spread
Brucella is also known as?
Undulant fever b/c the pt in some cases dvelops a cycling pattern of symptoms called undulant fever
How are CMV infections specifically diagnosed?
CMV can be isolated from saliva, cervical secretions, seme, urine, and wbcs for years after the initial infection
But difinitive diagnosis can be made by inclusion bodies
How are arbovirus infections spread?
Mosquitos, sometimes mosquitos can pass the virus down a generation
Chagas disease is also known as?
Trypanomsomiasis (sleeping sickness)
What are the 2 life forms of the trypsonomas cruzi?
: a large number created which cause the host cll to rupture
: Circle in blood to invade other host cells
: Yersinia pesits
Mode of transmission
: vector, bite of a rat flea (xenopsylla cheopis)
: Francisella tularnesis
: Inhalation, tick-bite, ingestion of conta,minated meat or water, directly by contact with an abrasion or cut while skinning an infected animal
: various bacteria of the genus brucella
: by occupational contact or by ingesting contaminated animal products
: the spirochete Borrelia Burgdorferi
: through the Ixodes tick
: Human herpesvirus 4
: Transmitted only after repeated contact with infected individuals
: person to person
: the parasite trypanosoma cruzi
: vector, the reduvid, a larged winged insect that feeds on sleeping hosts
: Wuchereria bancrofti and Brugia, both threadlike worms that lay coiled up in the lymphatic vessels of a human host for decades
Colonization of the heart by bacteria
Deposition of excessive amounts of platelets at the site
Depositin of fibirn at the site
Formatiion of mature vegetation
Organisms of the genus Grancisella cause
The most contagious form of plague is
The pneumonic form
