Q

How is the mouse inoculation test performed to test for Clostridium botulinum?

Q

What is the pathophysiology of most Rickettsial diseases?

A
  • Rickettsiae enter the blood, replicate in the endothelial cells →result in vascular damage and increase vascular permeability and leakage of fluid/ erythrocytes into the extravascular space
  • Vasculitis leads to ↓ platelets (petechiae) and ↓ albumin (peripheral edema)
  • Some organisms cause vasculitis and clinical signs more so than other organisms
  • Clinically – petechiation, bleeding (externally and internally), lameness, clinical signs from many systems

80
Q

What does it mean when we say canine herpesvirus is cytocidal?

A

Causing tissue necrosis and localized mucosal or generalized infections in young or immunocompromised animals.
its those bumps on ur cock, but don’t worry its not stable in the environment so you can’t get it from toilet seats!

81
Q

What is the pathogenesis of canine herpes?

A

fucking whores jk!
• Pups gets infected in utero, from passage through birth canal and contact with litter mates, from oronasal secretions from dam or through fomites (rare)
• If animal 2 weeks →mild or inapparant infection 

• Viral replication in the older animal is restricted to the nasopharynx, genital tract, tonsils, retropharyngeal lymph nodes, bronchial lymph nodes, conjunctival tissue and occasionally the lungs 

• In utero infections – depends on which stage of gestation, can result in abortions/ still births 

• Systemic infection – multifocal hemorrhagic necrosis (adrenal glands, kidneys, lungs, spleen and liver), DIC and thrombocytopenia 


82
Q

what are the clinical signs of the hep in neonates?

A

Acute death, dull, weight loss, lose interest in feeding, soft shit, rhinitis- serous to mucopurulent, petechial hemorrhage on mucus membranes

83
Q

What is the clinical signs in older pups and adults?

A

Mild or inapparent upper respiratory infection, genital infections, vesical lesions

84
Q

How do you diagnose the canine her?

A

Viral isolation, serology, PCR (MOST RELIABLE)

85
Q

How is transmission of rabies occur?

A

BITE from infected animal, rabies is carried in saliva

86
Q

What is the pathogenesis of rabies?

A
  • Virus enters peripheral nerve and ascends through the sensory or 
motor fibre. 

  • CNS signs develop n average 3 – 8 weeks post infection 

  • Once in the CNS it spread through intra-axonal means 

  • Cell necrosis occurs, and affects the forebrain, brainstem and spinal cord 

  • Severe damage to the motor neurons – ascending flaccid paralysis 

  • Then the virus spread back out of the CSN through the nerves – to the salivary glands 

87
Q

What are the clinical signs of canine rabies?

A
  • Prodromal phase (2-3 days)
  • Apprehension, nervousness, anxiety, solitude, variable fever 

  • Fractious animals become very affectionate 

  • Furious/ psychotic type (1-7 days) 

  • Increase response, bite at objects, photophobic, hyperesthetic 

  • Restless and roam 

  • Paralytic/ dump type (1-10 days) 

  • Cranial nerve paralysis, hypersalivation, inability to swallow 

  • Paraparesis, incoordination, terminating in coma and death 

  • Cat sometimes get the paralytic form straight after the prodromal phase
88
Q

What is the diagnosis of Rabies?

A

CDC, detection of virus in dermal tissues (FA testing, testing saliva)
Serology- used to document rabies immunization,
Pathology
PCR

89
Q

What is the treatment of rabies?

A

THERE AINT ANY, that nigga is fucked!

90
Q

lets go back to some epi shit… what do you do if animal is exposed and
Unvaccinated?
Vaccinated but not current?
Vaccinated and current?

A

Unvax- kill
Vax and not current- evaluate case by case
Vax and current- relax immediately and monitor closely for 45 days
