Abstract Content

Ectoparasites are skin dwellers to get food, heat, and protection found in every order of birds worldwide. Avian ectoparasites play an important role in the poultry industries via influencing the health, animal welfare, and the egg quality. A farmer had brought in four scavenging chick carcasses from the age of two to four months consecutively to Veterinary Research Institute (VRI) with the complaint of respiratory problem, diarrhoea, inappetence, seizures and sudden death in his flock over the past 30 days. General examination revealed chicks appeared very haggard as the skin was rough and ruffled with scales at the chest region. Both sides of the face and eyes were swollen with nasal and eye discharges. The hock joint at right legs were swollen too. Abnormalities were also observed at all the chick’s vital organs that includes the lung, liver, kidney and spleen. The lungs were pale and inflammed. The trachea was inflammed especially at the center. Further detailed post mortem examination of the scaly haemorrhagic skin at the chest areas revealed that the chicks were positive for the Megninia sp. feather mite infestation. Virology laboratory examination confirmed it as a mixed positive infection for Infectious Bronchitis QX strain. Bacteriology laboratory examination results were significant for Infectious Coryza, Pastereullosis and Ornithobacterium infection. Multiple severe respiratory infections were made as the final diagnosis with the complication of Megninia sp. infestation. Control and prevention of infections depends much on flock management by reducing the stress factors and planned vaccination programmes.
