| dc.description | Newcastle disease (ND) is an acute, contagious infection of pet, free living
and domestic birds. The causative agent is Newcastle disease virus (NDV)
which belongs to the genus Rubulavirus and falls in the subfamily
Paramyxoviridae of the family Paramyxoviridae (Alexander, 1997). The
virus 1s distributed all over the world either as naturally circulating virus or
as a vaccine virus. It has been established in at least 241 species of birds
representing 27 of 50 orders of the class Aves (Alexander, 1995b). ND is
widely variable in type and severity of the disease it produces. It is
complicated because different isolates and strains of the virus may induce
variations in the severity of the disease even in a given host, such as, the
chickens (Alexander, 1991). A variety of NDV isolates and strains have
been recorded around the world (Alexander, 1991; Ballagi-Pordany ef ai.,
1996). | en_US |
| dc.description.abstract | The control of ND relies on the use of safe and effective vaccines. Live
vaccines prepared with lentogenic strains of NDV are now more
commonly used in broilers than vaccines prepared from chemically
inactivated strains of NDV, mixed with adjuvant (Biggs ef al., 1988;
Alexander, 1991). This is because live freeze-dried vaccines can be
produced on a large scale at a relatively low cost. The vaccines are easy
to administer on a large scale, and rapidly stimulate humoral, cellmediated and mucosal surface immunity.
From this experimental work the principal objectives of the present
investigation it may be stated that production of HI-antibody was higher
in birds of group D vaccinated with Cevac Vitapest-L* compared to those
of group A vaccinated with Medivac NDLaSota”, group B vaccinated
with BCRDV(R) and group C vaccinated with Izovac. B, Hitchner”.
Thus, the Cevac Vitapest-L" was found to be superior to some extent
than Medivac ND-LaSota, BCRDV", Izovac B, Hitchnert. However, as
regards vaccination of chicks against NDV in earlier days the use of
lentogenic strains are recommended although it should be kept in mind
that vaccination with LaSota strains would cause considerately greater
problems in young susceptable birds than Hitchner B, strain and even
through LaSota induces a stronger immune response (OIE Manual, 4h
Edition, 2000). | en_US |
