Why do cancer of B cells form an African children infected by EBB but not in children in the United States were infected by this virus

A

No malaria in the US

20
Q

What is the prevalence of EBV infection in the human population

A

95% of human population

21
Q

Define with a human reservoir disease is unless three organisms that cost cardiovascular infections that are found in a human reservoir

A

Comes from a human, sub acute bacterial endocarditis, EBV, gram positive and negative sepsis

22
Q

Define’s on a stick disease less three cardiovascular/them Fetick disease is commonly acquired by direct contact with an infected animal and the reservoirs for each

A

Comes from an animal reservoir example anthrax pulmonary

23

Which diseases are caused by spore forming bacteria

A

Gas gangrene

24
Q

If you have been bitten by a tick saw reddish black spots all over your body and we’re running a fever what is the most likely disease you have

A

Rocky Mountain spotted fever

25
Q

What disease is caused by infection of the lymphatic system by worms and what is the vector of this disease

A

Filariasis elephantiasis caused by mosquito and black fly bites

26
Q

Define zoonotic a disease list three cardiovascular lymphatic disease currently acquired by contact with an infected animal

A

Anthrax (livestock) bacillus anthracis
Gangrene (livestock) clostridium perfrimgens
Tularemia (rabbits) francisella tularensis

27
Q

List five vector transmitted Cardiovascular and Lymphatic the Diseases and provide the vector transmitted by the organism

A

Lyme disease: vector ticks bacteria Borelia burgdorferi
Plague: vector tropical rat fleas
bacteria yersinia pestis
Malaria: vector mosquitoes organism plasmodium species
Filariasis: Victor mosquitoes and flies organism filarial worms
Rocky Mountain spotted fever: factor dermacentor ticks bacteria rickettsia rickettsii

28
Q

What organism and causes cutaneous anthrax and what is the reservoir

A

Bacillus anthracis

Cattle

29
Q

Define ischemia and describe the cardiovascular infection that can result in tissue necrosis and gas production

A

Ischemia tissue becomes necrotic due to very poor blood circulation Gas gangrene caused by clostridium per fringes.

30
Q

What is the most common vector transmitted Cardiovascular Diseases in the United States where is the disease most common and how would you diagnose?

A

Lyme disease caused by Borelia burgdorferi spirochaete shaped, reservoir field mice transmitted by ticks, most commonly found on the East Coast diagnose classic bull’s-eye rash
