Abstract
A mixed viral infection of Newcastle Disease (ND) Mareks Disease (MD) and Avian Leukosis (AL) was reported in village chickens. Analysis of the deduced amino acid sequences of the F protein cleavage site of ND virus showed that the isolate was virulent with sequence KRRKR for the C-terminus of the F2 protein and phenylanine (F) at residue 117 the N-terminus of the F1 protein. Basic Local Alignment Search Tool (BLAST) analysis showed the isolate was ND which was 96 similar identity with Indonesia Sukorejo genotype VII MD 99 similar identity with China very virulent strain and ALV 100 similar identity with Taiwan ALV strain. Due to the free ranging type of management causes of the diseases in the poultry were uncertain as many factors can contribute to the disease occurrence. However good hygiene practices can help to improve the farms sanitary. Basic biosecurity system can be applied although the success may be limited. Vaccination is another alternative that can be considered to prevent the diseases with the help from certain parties.
