Q
  1. Marek’s disease.

Pathogen
Types and CS

A

Alphaherpes, Mardivirus , GaHV-2,3

Two serotypes:

  1. A-D - causing marek, diff virulence
  2. Non pathogenic strain

a. very virulent: tumors (can break through vaccine protection)
b. virulent: tumors and transient paralysis
c. lower virulence: neurological form
d. avirulent: no clinical signs

Classical neurological form:
o Strains of mild virulence
o Growers and in (young) hens
o sporadic, long lasting, recovery after 1 year of age

Transient paralysis:
o	Strains of higher virulence
o	4-7 weeks old, non-vaccinated
o	sporadic
o	transient recovery→ may lead to visceral form

Acute, lymphoproliferative:
o In non-vaccinated → after 6 weeks of age
o In vaccinated → growers or beginning of laying
o Long-lasting disease in the flock
o CNS symptoms may develop

Peracute or anaemia:
o Rarely → in 3-6 week-old chicken
