Vaccination against Fowlpox Virus Via Drinking Water

Abstract

ABSTRACT. The oral vaccination against Fowlpox was investigated via drinking water containing the F132-c strain of Fowlpox virus to be effective even though the vaccine virus-titer was 10 4 TCID 50 /dose each time. When the virus-titer of the F132-c strain was 10 4-5 TCID 50 /dose per single drinking water vaccination, 90% or more of chickens were not protected, however, they were protected when vaccinated twice via drinking water. A weak immune response occurred by a slight infection after the first vaccination, and due to memory cells, a booster could work well after the second vaccination. These results suggest the possibility of reducing both the amount of virus required for a vaccine via drinking water and the labor cost in the field. KEY WORDS: Fowlpox virus, oral vaccination.

Avian influenza vaccines: a practical review in relation to their application in the field with a focus on the Asian experience

“…However, in the case of the fowlpox vaccine, only limited protection is conferred using intranasal, eye drop, or drinking-water administration methods [33].…”

“…Recombinant vaccines are of great interest for oral or mucosal administration because of the flexibility in the choice of a vector suitable for these administration routes [25]. However, in the case of the fowlpox vaccine, only limited protection is conferred using intranasal, eye drop, or drinking-water administration methods [33].…”

Current situation and genomic characterization of fowlpox virus in lower Egypt during 2022

“…The extremely contagious APV has been found in over 200 different bird species, including both domesticated and wild birds ( Hye et al, 2013 ). The fowlpox virus ( FPV ) reduces chicken productivity and it is one of several issues that developing countries' poultry sectors must deal with due to significant financial losses caused by decreased broiler growth rates, blindness, significantly reduced egg output in layers, and high morbidity with elevated mortalities, primarily in the diphtheritic type, that approach 50 to 100% ( Ariyoshi et al, 2003 ).…”

Isolation and molecular detection of Avipox virus from field outbreaks in Mymensingh, Bangladesh

“…It is still a malady and an enzootic to the growing chicken of any age, sex, and breed either in organized or in rural poultry farming system in Bangladesh [5]. This is an economically important disease in commercial poultry farming [6] as it may cause to reduce egg production and growth rate and increase the mortality rate [7]. Though it is an economically important disease of poultry, vaccination to the commercial flocks has helped to reduce the losses associated with the disease in the population of chickens [8].…”
