A, Haemagglutination inhibition titer mean values of serum sample(s) taken from experimental bird species (Japanese quail and myna) on Day 0, 7 and 21 of the experiment showing higher HI titers on day 21 as compared to day 0 and 7.
B, Mean death time (days) was recorded in experimental bird species (Japanese quail and myna) and early mortality was seen in Japanese quails as compared to mynas post-inoculation of VVND virus.
C, Mortality percentage was calculated in experimental bird species (Japanese quail and myna) and higher mortality rate was recorded in myna (75% intramuscular group) as compared to Japanese quail. Different groups of myna showed susceptibility to VVND whereas no mortality was recorded in Japanese quail (contact exposed group).
D, Dead birds were examined for postmortem findings and lesions on major infected organs and were scored according to severity of lesions. The average lesions score of oral groups of both experimental bird species (Japanese quail and myna) were higher than intramuscular and contact-exposed groups.
