bacterial & Viral diseases transmitted by arthropod vectors
Show Answers:

  1. what disease was spread by,rats,squirrels,prarire dogs to humans by fleas.
    • Plague
    • etiologic agent:Yersenia pestis
    • bacterial or viral: Bacterial
    • lab results:G(-) coccobacilli
    • vaccine info:
    • symptoms:
    • transmission: could acquire bacteria by eating an infected rodent or by being bitten by an infected flea; pneumonic plague is communicable between humans via respiratory droplets
    • reservoirs/vectors: rats,squirrels, prairie dogs to humans by fleas
  2. what plague occurs within a week of being bitten by a flea?
    • Bubonic plague
    • etiologic agent :Yersenia pestis
    • bacterial or viral :Bacterial
    • lab results:G(-) coccobacilli
    • vaccine info :
    • symptoms:"bubo" (swollen, painful lymph node especially in axillary region, groin, or neck). Bacteremia (blood infection) follows Hemorrhages
    • turn skin black (“Black Death”). Bubonic can turn into Pneumonic plague
    • below).
    • transmission: eating infected rodent or by being bitten by and infected flea
    • reservoirs/vectors: rats,squirrles,prairie dogs to humans by fleas
  3. what plague is caused by bubonic plague?
    • Pneumoic plague
    • symptoms: cough develops with sputum production, which may be bloody, and increasing chest pain and difficulty in breathing,As the disease progresses, hypoxia (low oxygen concentration in the blood) and hemoptysis (coughing up blood) are prominent.
    • transmission:Bubonic plague can turn into pneumonic plague if bacteremia occurs and bacteria travel to lungs. Can also occur when contaminated respiratory droplets expelled by infected persons are directly inhaled by another person
  4. what disease is often called "lawnmower disease"
    • Tularemia=Rabbit Fever=lawnmower disease
    • etiologic agent: Francisella tularensis
    • bacterial or viral: Bacterial
    • lab results:G(-) bacillus
    • vaccine info: No vaccine but boosters
    • symptoms: fever,severe headache, and buboes; one form can lead to a septicemia that resembles typhoid fever
    • transmission: breaks in skin, bite from arthropod vector inhalation of aerosols during skinning, consumption of contaminated meat; capable of surviving outside of a mammalian host for weeks at a time and has been found in water, grassland, and haystacks - aerosols containing the bacteria may be generated by disturbing carcasses due to brushcutting or lawn mowing (think about road kill rabbits); at risk: taxidermists, hunters, trappers, lawnmower operators
    • reservoirs/vectors: cottontail rabbits and other animals squirrels, rats,hogs
  5. what disease can be transmitted by ticks and human body lice?
    • Relapsing fever
    • etiologic agent: Borrelia recurrentis
    • bacterial or viral: Bacteria
    • lab results:
    • vaccine info: can be cured with antibotics
    • symptoms: high fever, respites, and shorter periods of fever due to changes in organisms antigens
    • transmission:ticks and human body and head lice
    • reservoirs/vectors: ticks and lice
  6. what disease is transmitted by ticks and can cause bull's eye rash?
    • Lyme Disease
    • etiologic agent: Borrelia burgdorferi
    • bacterial or viral: Bacterial
    • lab results:
    • vaccine info:antibiotics
    • symptoms: flu-like symptoms, rash erythema chronicum
    • migrans, which characterizes the disease (“bull’s-eye” rash – concentric rings around initial site of tick bite); other symptoms include arthritis, myocarditis, etc.; can have lasting effects on the nervous system if not treated
    • early; often misdiagnosed
    • transmission: deer ticks and other ticks (Ixodes dammini)
    • reservoirs/vectors: white footed deer mouse is the main reservoir; white-tailed deer, dogs, etc. are also
    • reservoirs
  7. what disease is a monkey the reservoirs?
    • Yellow Fever
    • etiologic agent: yellow fever virus
    • bacterial or viral: virus
    • symptoms: suffer severe liver damage and become jaundiced
    • transmission: to humans by mosquitoes
    • reservoirs/vectors: monkeys
  8. what major diease is caused by a mosquito?
    • West nile virus
    • bacterial or viral: virus
    • lab results
    • vaccine info
    • symptoms
    • transmission: mosquito
    • reservoirs/vectors
