NEWCASTLE PROBLEMINDE YAPILMASI VE YAPILMAMASI
GEREKENLER

• Uzm.Vet.Hekim Güney GÖKÇELIK

2
NEWCASTLE

• PARAMYXOVIRUS
• GENOTIP / 1---gt9

3
VIRÜLANS VE TROPIZM

• VISSEROTROPIK VELOJENIK (EKSOTIK NEWCATL)
• NÖROTROPIK VELOJENIK
• PNÖMOTROPIK MEZOJENIK
• RESPIRATORIK LENTOJENIK
• ENTEROTROPIK APATOJENIK

4
INCUBATION PERIOD IS VARIABLE

• According to virulence,population and
  susceptible shows the variability of 2 -15 days.
• Expected ,between 2-6 days in chickens.

5
MORBIDITE/MORTALITE YÜKSEKTIR

• Lentojenik suslarda morbidite yüksekken mortalite
  önem kazanmaz
• Mezojenik suslarda yine yüksek morbidite ve
  10lara varabilecek mortalite beklenebilir
• Velojenik suslarda,asisiz hayvanlarda morbidite
  ve mortalite 100e ulasir
• Asilanmis hayvanlarda bile 30 ile 90 arasinda
  degisen mortalite bildirilmistir

Örnek asi virus sujlarinin virulans(ve ICPI) ve tropizm özelliklerine göre siniflandirilmasi (VAN ECK ve ark., 1991 ALEXANDER,1998)
VIRULANS ASI VIRUSU ICPI TOPIZM
Mezojenik Roakin 1,45 Respiratorik (ICPI 1 ila 2) Komarov 1,41 Respiratorik
Lentojenik Lasota 0,44 Respiratorik F 0,25 Respiratorik (ICPI0,2 ILA 0,7) VG / GA - Enterik Hitchner B1 0,2 Respiratorik
Apatojenik Ulster 2C 0,04 ila 0,2 Enterik (ICPI 0,0 ila 0,2) Phy LMV 42 0,16 Enterik

SENSITIVE SPECIES

• 236 bird species have been reported to be
  sensitive
• The most sensitive are chicken.
• Goose- ducks not show clinical sign,might be
  carrier
• Turkeys are more serious spreader than chickens
• Waterfowl are emit and carry lentogenic strains.
• Also pigeons are endemic to lentogenic and
  mesogenic strains.
• Nervous signs characterized in cormorant.
• Many different forms consist in Pisittasins.
• Nervous signs are observed in ripper birds.
• Respiratory problems are discovered in ostriches.

8
RESISTANT VIRUS

• Suspect flock-11 C 36 C up to 255 days,
• In 8 C 14 months and in freezing weather
  condition for years ,
• 300 days of carcasses of bone marrow ,
• Intensive carcass consuming dogs 22 days,
• In Turkey intestines until 12 months,
• In summer term7 days,in spring 14 days and in
  winter30 days have been reported to survive.

9
RESISTANT VIRUS

• In contaminated materials 10-14 days,
• In soil 20 C ,22 days ,
• Earth worms 4-18 days,
• In experimental contaminated lake water have been
  reported to survive 11 -19 days.

10
PROPAGATION IS VERY EFFECTIVE

• 3-4 days after infection by feces and 3-4 weeks
  by droplet and feces
• Feed,Water,Tools,Pad,Equipment,People, Frozen
  meat,disposable nature of the dead, wild birds,
• Maggots,Mites,Rabbit,Cat- Dogs, contamination
  from infected breders egg shell

11
FASTER DISPERSION

• Agent, can reach in a calm air condition 50 m and
  the wind event 1-2 km far away.

12
MISTAKES RELATED WITH PRODUCERS

• Do not want to warning
• Besides poultry houses, kept broiler or laying
  hens
• Feed cats and dogs
• Even with next-door neighbour not to share their
  problems
• In case of problem,do not take a joint decision

13
MISTAKES RELATED WITH VETERINARIAN PROFILE

• Poultry species,age,susceptibility
• Factor strain,virulence
• Vaccination schedule
• Enviromental condition
• Secunder infections
• VARIABILITY FIGHT SCHEDULE

14
DO WE REFER TRUE?

• Clinical and necroscopic error
• Smiliar disease
• Business blindness
• Durable insistence

15
OTHERS

• To ignore,application of Gumboro hot vaccine or
  other immünosüpressif agents
• Vaccination according to company-producers
  pressure or wrong suggestions way
• Failure to report under pressure of Company-
  Producers
• Do not warn, around producers

16
NEGATIVE EFFECTS RELATED WITH STATE

• In fight main and general measures should be
  recommended by the Ministry and maintained under
  control.
• Epidemiological surveillance by computer and
  recording system should be establish.
• In fight diseases should be the right sort of
• Between science and practical disconnection
  should be corrected and work together.

17
GOVERNMENTAL

• Ministry officials, field staff and producers
  provided co-operation to each other.
• All staffs beyond the fuzz behaviour must have
  sufficient knowledge and having discretionary
• Country poultry vaccination must be controlled

18
DURING THE EPIDEMIC NECESSITIES

• Do not make faster dispersion that consider
  evaulation of sick chickens and make them cut
• Do not carry sick chickens where there is no
  disease
• Every two hours collect all the dead and burn
  them
• Cleaning the rest of the coops, do not put
  chiicks at least 1 month.
• When you realize,it will be too late thus do not
  have any hopes from vaccination sick animals.
• Warn surroundings
• Accept,the importance of vaccination and
  biosecurity is equal 50 of the rate.

19
KÜMES TEMIZLIGINDE

• Virus100 Cde 1dk ve 56 Cde 3 saatte inaktive
  olur
• Günesin direkt UV isinlari 15 dk içerisinde
  öldürücüdür
• Eter,Fenoller,Formalin ve Iyotlu dezenfektanlar
  etkindir.
