BookPublisher: 1991Subject(s): Department of MicrobiologyDDC classification: 0217,T Dissertation note: This research work was undertaken to assess the importance of Pseudomonas aeruginosa as a poultry pathogen. For this purpose 4000 samples comprised of spoiled eggs 1000, dead in shell chicks 1000, chicks dying during first week 1000, subsequent deaths 1000, were prodessed.
Pseudomonas aeruginosa was isolated from 302 birds giving a percentage of 15.1. While examining spoiled hatching eggs Pseudomonas aeruginosa was revealed in 131 eggs giving a percentage of 13.1 and from 134 dead in shell chicks giving a percentage of 13.4.
The agewise incidence of Peudoinonas aeruginosp infection was zero percent in day old chicks, 25.6 percent in one week old, 24.84 percent in 2 weeks old, 12.69 percent in 3 weeks old, 11.76 percent in 8 weeks and 7.46 in 9 weeks, 7.69 percent in 11 weeks old and 9.32 percent in 12 weeks old and no incidence was observed in chicks of less than one week and in chicks beyond 12 weeks of age.
Pathogenicity of the isolate was studied in one day old chicks and 10 days old developing chick embryos. Twenty six out of 30 chicks died within one to 7 days whereas all the embryos died within 24 hours to 48 hours post-inoculation. The post-mortem examination in dead chicks showed haemorrhagic oedema at the site of inoculation and in dead embryos generalized congestion below the skin. Pseudonionas aeruginosa was re-isolated from heart blood and liver of these chicks and from yolk and chorioallantoic fluid of the embryos.
