poxviridae Flashcards
fowlpox transmitted by
arthropods
cowpox virus is preserved by
deep freezing or freeze drying for several years in 50%glycerol saline
fowl pox virus is related to
pigeon pox virus
fowl pox virus spread through
wounds and aberrations
mechanical transfer by
mosquito
lice
ticks
cutaneous form of fowl pox
contact of virusin aberrated skin
- **papules and vesicles in comb wattles shank feet
- **respiratory lesions cause obstruction
diphtheric/wet form
caused by
droplet infection
lesions coalasce in diphtheric form of cowpox to form
diphtheric
pseudomembrane
diphtheric pseudomembrane causes
asphyxiation and death
mortality rate of fowl pox
50%
birds with large comb and wattle are at high risk
economic loss of fowl pox is due to
drop in egg production
pathogenesis of fowlpox
multiplication of virus results in proliferation of epithelial cells
proliferations of epithelial cells leads to
nodule formation in skin waffles comb conjunctivitis
course of fowl pox disease is
chronic and signs of anorexia loss of weight
***fall in egg production
affected cells of fowlpox causes
***hydropic degeneration
/ballooning
affected cells of fowlpox causes
***hydropic degeneration
/ballooning
in fowl pox formation of simple cytoplasmic inclusion bodies called
bollinger bodies
borrel bodies are
infectious viral particles embedded in matrix of bollinger bodies
diagnosis of fowlpox is by
- **clinical symptoms
* *virus enoculated into chicken embryo
prevention and control of fowl pox
improve management and hygiene
***vaccine
live fowl pox vaccine is prepared in
chicken embryo cell culture
vaccine for fowlpox is in
scarification of the skin in the thigh region
recombinant fowl pox vaccine contains
ND
avian influenza
ILT
IBD
most pathogenic among pox virus is
canary pox
