Q

Gangrene susceptible and travel

A

Diabetic, abortions or gunshot wounds

Endospore, germination, deep cleaning can reduce spores

19
Q

Symptoms and toxin of gangrene

A

Symptoms: abrupt pain, swelling, ooze blood tainted fluid from ruptured vessels, blackening of tissue

Toxin: X toxin, attacks blood vessels, RBC and WBC, lecithin of cell membrane

20
Q

Why does swelling take place due to gangrene

A

Swelling from gas production H+ and CO2
-snap, crackle, pop noises and foul orders

21
Q

Spotted fever is caused by

A

Ricksetti ricksetti

22
Q

Spotted fever
-risk, differs form measles, symptoms

A

-makes its way to heart and destroys valves
-differs from measles as there is a rash on white parts of our bodies (soles of feet, hands)
-cause fever, rash (on white parts)

23
Q

HHSV-4 or Epstein BARR virus causes

A

BURKITTS LYMPHOMA

24
Q

BURKITTS lymphoma

A

-tug a war on lymphocytes
-fast growing tumour on jaw

25
Q

Latency of BURKITTS

A

Not latent in herpes virus, latent in B lymphocytes

26
Q

BURKITTS productive infection vs nonproductive

A

P- not latent

N- latent

27
Q

Infectious mononucleosis

A

Spread through saliva
-B lymphocytes are non productive

28
Q

Symptoms of infectious mononucleosis

A

-starts with fever sore throat, pus, EB in saliva for 18 months, 1.8 million college students fatigue

29
Q

A

Infected cells swell and have inclusions
-latent in T cells
-causes Owl’s eyes

33
Q

CMV when transmitted across placenta

A

35
Q

Malaria is caused by

A

Protozoa
-plasmodium vivax

36
Q

Two hosts of malaria

A

Definitive - mosquitos
Intermediate- human

37
Q

Malaria causes

A

Fever, vomiting, severe headaches, pain in muscles

38
Q

Fever phase of malaria
-paroxyme cycle

A

Cold phase, hot phase, wet phase (drenched)

39
Q

Life cycle of malaria: mosquito bite—>

A

Sporozoite form—> though CV system to liver—> releases mature asexual merozoities in blood

40
Q

Life cycle of malaria: merozoites in blood

A

Attack RBC—> form ring stage, which will produce more merozoites—>cycle continues

41
Q

Life cycle of malaria: cycle continues

A

RBC dies and releases merozoites —> merozoites can become m/F gametes which cannot mature (wont spread at this point)

42
Q

Life cycle of malaria: m/F gametes created

A

Mosque bites—> zygote formation —> new sporozoites

43
Q

Malaria symptoms, smear, treatment

A

-enlarged spleen and liver, severe anemia
-need blood smear
-quinine drug
