ND indication symptoms and the distribution of LaSota in different organs. A Intestinal lymphoid follicle haemorrhage and swelling; B glandular stomach papilla haemorrhage; C LaSota viral loads in different organs. Different organs were excised from three chicks randomly chosen from each group at 3 weeks of age to determine the LaSota viral load, which was represented as log10 copies/µL (mean value ± error). The NDV viral load value of the contaminated group was compared with that of the corresponding non-contaminated group based on Duncan‘s multiple-range test. *Indicates significant difference (P < 0.05) between the two experimental groups.
