What is Q fever?
an infectious fever caused by the bacterium Coxiella burnetii, which may be transmitted to humans from cattle, sheep, and other domesticated animals.
What spore former microbe is gram negative?
Coxiella burnetii
What is a causative agent of q fever?
Q fever caused by Coxiella burnetii bacterium
Propose a life cycle for coxiella?
Coxiella burnetii typically enter human via enhalation of aerosols during the birthing of animals such as calves. The Small cell variant form attaches to a host cell, usually to a macrophage within the lungs. The macrophage ingests the organism into a phagolysosome where the acidic pH activates the Coxiella's metabolic enzymes. As the Coxiella reaches maturity, it begins sporogenesis and ultimately produces spores. The infected macrophage lysis and the spores are released to infect other cells. The spores are highly resistant to desication and chemical contact such as bleach. This allows them a long and protected life outside of the host. I'm not exactly sure about the Large cell variant form, but one could guess that it is the mature cell that undergoes sporogenesis.
Who is most at risk for contracting Q fever?
As a result, C. burnetii can cause infection through contaminated milk, or when humans come into contact with the fluids or tissues produced when a cow or sheep gives birth
What is cox infection?
An infection common from anal sex, semen weakens the immune system in the rectum. I dispute the above - what organism is causing this? Semen does not weaken the immune system.Cox could refer to Coxiella or Coxsackie.Coxiella burnetii - intracellular bacteria causing Q fever.Coxsacieviruses - enteroviruses spread by contact with faeces (not only by anal sex) or by respiratory secretions. They cause a wide range of conditions.
How can Q fever be contracted?
As a result, C. burnetii can cause infection through contaminated milk, or when humans come into contact with the fluids or tissues produced when a cow or sheep gives birth
Obligate Intracellular Parasites?
Gram negative rods or coccobacilli 2) Unable to reproduce outside of a host cell. 3) Lost ability to synthesize needed for extracellular growth. 4) Transmitted when a blood-sucking arthropod (tick or louse) takes a blood meal from a human. 5) Rickettsia rickettsii - Rocky Mountain Spotted Fever 6) Rickettsia prowazekii - epidemic typhus 7) Coxiella burnetii - Q fever 8) Survives outside host & does not require an arthropod for transmission.
