| dc.description | Newcastle disease (ND) is an acute, contagious infectious disease 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 is 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 et al., 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
and layers than vaccines prepared from chemically inactivated strains of NDV, mixed
with adjuvant. 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, cell-mediated 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 A (512)
vaccinated with ND LaSota®, compared to those of group B vaccinated with RDV
(Mukteswar strain);256, group C vaccinated with ND B1 (B1 strain) Hitchner®;2.78
at 6 weeks after vaccination. Thus, the ND Lasota® was found to be superior to some
extent than . ND B1, Hitchner. 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 considerably greater
problems in young susceptable birds than Hitchner B, strain and even through LaSota
induces a stronger immune response (OIE Manual, 4" Edition, 2008). | en_US |
