BookPublisher: 1994Subject(s): Department of Clinical Medicine & SurgeryDDC classification: 0389,T Dissertation note: A total of 250 desi birds, selected randomly, from different villages of district Lahore, were divided into two groups. The group-I composed of 125 apparently healthy birds whereas 125 apparently weak and emaciated birds were present in group-IT. Avian tuberculin test was employed to diagnose the tuberculosis. A 0.1 ml of avian tuberculin (MCSM) procured from VRI, Lahore, was injected into left wattle whereas right wattle was kept as uninjected control and test was read after 48 hours. Only 6 birds (2.4%), all belonged to group-IT, were found tuberculin positive. Haematological studies of these six tuberculin positive birds were carried out along with 10 healthy desi birds for comparison. There was decrease in erythrocytic count (EC), haemoglobin value (Hb) and packed cell volume (PCV). The average values of EC, Hb and PCV of infected birds were 1.94x106/µ1, 8.86 g/dl and 22.69% respectively. On the other hand, leukocytic count (LC) was increased and found to be 37.33x10/il on average. A significant change in differential leukocytic count (DLC) was also observed with an increase in the proportion of polymorphs and monocytes and fall in lymphocytes. The lymphocyte to heterophils ratio was the inverse of that in healthy birds. On post-mortem, a large number of tubercles of varying size were noticed on liver, spleen and intestines. No birds showed lung lesion except one.
