R. prowazekii primary mode of transmission to humans is through the bite and feces of body lice, and inhalation. Humans are the only reservoirs of R. Prowazekii.
Live media needs to be used to culture and isolate the organsim such as yolk sacs in fertilized chicken eggs.
The quicker the disease is detected, Tetracycline or Chloramphenicol can be given, the prognosis will improve.

Where is rickettsia richettsii mostly found?
Rickettsia rickettsii is the cause of Rocky Mountain spotted fever (RMSF) and is the prototype bacterium in the spotted fever group of rickettsiae. Rickettsia rickettsii is found in the Americas and is transmitted to humans through the bite of infected ticks. The bacterium infects human vascular endothelial cells, producing an inflammatory response. The pathogenesis of RMSF is discussed in some detail below.
Is scarlett fever a virus or a bacteria?
Typhoid or Typhoid fever is an infection that causes diarrhea and a rash -- most commonly due to a type of bacteria called Salmonella typhi. Sometimes confused with Typhus, which is caused by one of two types of bacteria: Rickettsia typhi or Rickettsia prowazekii.
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.
What is the replication of rickettsia?
Rickettsia replicates within the host cell cytoplasm through a process known as binary fission. This involves the bacterium dividing into two daughter cells, leading to the multiplication of the organism within the host cell.
A test used to detect anti-Rickettsia antibodies in a patient is the?
Indirect immunofluorescence assay (IFA) is commonly used to detect anti-Rickettsia antibodies in a patient. This test involves exposing the patient's serum to Rickettsia antigens and then using fluorescently labeled antibodies to detect any bound antibodies. Positive results indicate a past or current infection with Rickettsia bacteria.
How severe is rickettsia prowazekii?
Rickettsia prowazekii is an intracellular, bacillus bacterium that is the cause of epidemic typhus in humans. If it is untreated, the infection may increase and is definitely dangerous. It can even lead to death. It has cure so it must be treated timely.
Is typhus a virus or bacteria?
bacteria
How do people get epidemic typhus?
caused by Rickettsia prowazekii, which is carried by body lice. When the lice feed on a human, they may simultaneously defecate. When the person scratches the bite, the feces (which carries the bacteria) are scratched into the wound.

How does rickettsia attack?
Rickettsia attacks by invading host cells, particularly endothelial cells lining blood vessels. They enter these cells through mechanisms such as phagocytosis or by exploiting the host's cellular machinery. Once inside, Rickettsia replicate and spread, often leading to inflammation and damage to the vascular system, which can result in symptoms like fever and rash. The bacteria primarily rely on the host's resources for survival and proliferation.
Typhoids fever is caused by?
It is a bacterial infection due to salmonella typhi. It is spread by eating or drinking water contaminated by feces of an already infected person
How do you get Rocky Mountain Spotted Fever?
Rocky Mountain spotted fever is a tick bourne illness. It travels through tick bites and is actually one of the more severe tick bourne diseases.It can also be spread from people in large crowds or people who aren't clean.
What animal spreads typhoid fever?
Mosquitoes have been known to transmit Typhoid. They can infect you with their bite.
