Publisher: 1992Dissertation note: A study was undertaken to isolate and characterize Newcastle Disease Virus Strains involved in field outbreaks.
A total of 1000 diseased/dead birds ( broilers, layers arid non-discript birds ) were examined for this purpose. The isolation of the virus was attempted from composite samples comprising lungs, liver, spleen, brain and proventriculus of the suspected birds, which was inoculated in embryonated eggs through allontoic cavity route. Out of the total birds examined only 6(0.06%) yielded ND Virus. All the strains present in allontoic fluid gave a positive reaction to spot haemagglutination test, on fowl RBCs. The isolates were confirmed as Newcastle disease pathogen through a positive reaction to haemagglutination inhibition test conducted with known positive sera against Newcastle disease.
Various value values obtained for mean death time (MDT) were 48, 60, 70, 72, 48 and 62 hours for isolates.
No. 1, 2, 3, 4, 5, and £ respectively.. Values of intracerebral pathogencity index far isolated No. 1, 2, 3, 4, 5, and 6 were 1.71, 1.68, 1.58, 1.46, 1.7 and 1.65 respectively. The intravenous pathogenecity index varies recorded were 230, 200, 1.91, 1.88, 2.08 and 1.93 for isolate No. 1, 2, 3, 4, 5, and 6 respectively.

Publisher: 1993Dissertation note: This experiment was conducted to study the immunogenic response of '14 strain of NOV which was administered through different routes normaly practiced in Pakistan (eyedrop, drinking water, subcut and intramuscular)
Birds in group A were vaccinated intraocularly on 7th day of age and then on 21st day of age they were again vaccinated subcutaneously with '14 strain of NOV . The GMT titer on 12nd day of their. age was 169 and they showed 757. survival when challenged with VVNDV.
Group B was administered V4 strain of NDV in drinking water twice on 7th day of age and on 21st day of age. Their GMT HI titre on 42nd day was 104 .They showed 70%. protection percentage when challenged with virulent virus.
Chicks of group C were vaccinated introcularly with V4 strain on 7th day of their age and intramuscularly on 21st day of their age with V4. Their sera when analysed on 42nd day of age indicated GMT HI titre of 181. They showed highest protection 807. when , Challenged with virulent virus.
Group 0 was vaccinated intraocularlywith Mukteswar strain of MDV on 7th day again substaneously on 2lth day . Their GMT H.I titre was 194 on 42nd day of age.
Challenged with VVNDV protected 85% birds.
This study indicates that V4 strain of NOV induces higher H I titer and protection percentage when administered 1/rn than S/C and drinking water routes. However Mukteswar strain gives more HI titer and protection than V4 strain through S/C route.

Studies On Avian Pasteurolosis, Characterization Of Isolates From Diseased Carrier Birds

Material type: ; Format:

Publisher: 1992Dissertation note: A total of 1000 birds (600 diseased/dead and 400 healthy) were examined for the isolation of the Pasteurelia muitocida so as to have an idea about the incidence of fowl cholera in the poultry flocks (Broiler and Layer) and the percentage of the carriers for the organism maintiined in and around Lahore.
Out of 600 diseased/dead birds examined 1% yielded Pasteurella inultocida. None of the 400 healthy birds proved carrier for organism. All the six isolates produced small, greyish, circular colonies on blood agar. The growth in the Triptic Soya agar appeared in the form of convex, entire edged, mucoid colonies having a diameter of ljim.
There was not any growth on MacConkey agar. All the isolates fermented glucose, sucrose, mannose, mannitol, xylose and fructose with production of both, acid and gas. Likewise all the six isolates were positive for nitrate reduction, catalase/reduction, indole production H2sproduction nitrate reduction tests.
None of the isolates was positive for gelatin liquification methyl red test, voges-Proskauer test, and urease production test. All the isolated organisms were non-motile.
All the isolates proved pathogenic to mice. Antibitics including chloramphenicol, Gentamicin Furadantin, Streptomycin and Nalidixic acid were highly effective against all the isolated strains. However the isolates were insensitive to Tetracycline and Erythromycin.
