  1. NEWCASTLE PROBLEMİNDE YAPILMASI VE YAPILMAMASI GEREKENLER Uzm.Vet.Hekim Güney GÖKÇELİK

  2. NEWCASTLE • PARAMYXOVİRUS • GENOTİP / 1--->9

  3. VİRÜLANS VE TROPİZM • VİSSEROTROPİK VELOJENİK (EKSOTİK NEWCATL) • NÖROTROPİK VELOJENİK • PNÖMOTROPİK MEZOJENİK • RESPİRATORİK LENTOJENİK • ENTEROTROPİK APATOJENİK

  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. MORBİDİTE/MORTALİTE YÜKSEKTİR • Lentojenik suşlarda morbidite yüksekken mortalite önem kazanmaz • Mezojenik suşlarda yine yüksek morbidite ve % 10’lara varabilecek mortalite beklenebilir • Velojenik suşlarda,aşısız hayvanlarda morbidite ve mortalite % 100’e ulaşır • Aşılanmış hayvanlarda bile % 30 ile 90 arasında değişen mortalite bildirilmiştir

  6. 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.

  7. RESİSTANT VİRUS • 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.

  8. RESISTANT VİRUS • 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.

  9. 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

  10. FASTER DISPERSION • Agent, can reach in a calmaircondition50 m and the wind event1-2 km far away.

  11. MISTAKES RELATED WITH PRODUCERS • Do not want to warning • Besides poultry houses, kept broiler orlaying 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

  12. MISTAKES RELATED WITH VETERINARIAN PROFILE • Poultry species,age,susceptibility • Factor strain,virulence • Vaccination schedule • Enviromental condition • Secunder infections VARIABILITY FIGHT SCHEDULE

  13. DO WE REFER TRUE? • Clinical and necroscopic error • Smiliar disease • Business blindness • Durable insistence

  14. 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

  15. NEGATİVE EFFECTS RELATED WİTH 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.

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

  17. 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 putchıicks 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 equal50% of the rate.

  18. KÜMES TEMİZLİĞİNDE • Virus;100 C’de 1dk ve 56 C’de 3 saatte inaktive olur • Güneşin direkt UV ışınları 15 dk içerisinde öldürücüdür • Eter,Fenoller,Formalin ve İyot’lu dezenfektanlar etkindir.

  19. DİNLEDİĞİNİZ VEDE UYGULAYACAĞINIZ İÇİN TEŞEKKÜR EDERİM
