A longitudinal study of the incidence of major endemic and epidemic diseases affecting semi-scavenging chickens reared under the Participatory Livestock Development Project areas in Bangladesh

“…The country has been producing two live vaccine: Baby Chick Ranikhet Disease Vaccine */BCRDV (F strain of NDV) and Ranikhet Disease Vaccine */RDV (Muketswar strain). Despite having the introduction of the vaccine, ND still remains one of the major problems to the village chickens in Bangladesh, like other parts of the world (Spradbrow, 1988;Werner, 1994;Kama et al ., 2000;Tu, 2000). Results of the present study further illustrate that ND could be found with significantly higher trend in the vaccinated birds under the PLDP area than in the unvaccinated birds.…”

Loop-Mediated Isothermal Amplification for Rapid Detection of Newcastle Disease Virus

“…Presently, this disease is still widespread in many countries of Asia, Africa, the Americas, and also Europe (3,25). Newcastle disease virus (NDV) is present in a variety of strains which differ widely in virulence from causing symptomatic to lethal infection (6).…”

Virulence of Newcastle Disease Virus and Diagnostic Challenges

“…For the purpose of disease prevention it would be ideal to predict the potential of each genotype of low virulence NDV to mutate into a virulent form (Miller et al, 2010). The highly pathogenic form of ND is a serious problem, either as an enzootic disease or as a cause of regular, frequent epizootics throughout Africa, Asia, Central America and parts of South America (Copland, 1987;Spradbrow, 1988;Rweyemamu et al, 1991;Alders and Spradbrow, 2001). In Europe sporadic epizootics occurring despite vaccination programmes (Kaleta and Heffels-Redmann, 1992).…”
