Immunological status in one-day old ostriches – preliminary results
Any kind of contamination in ostrich hatchlings in their first 24 to 48 hours may cause difficult infections, premature death and consequent loss to ostrich farmers. As farmed ostrich chicks under intensive breeding programs are subject to a larger number of stressful circumstances (transportation, artificial feeding, confinment in numbers, human visitors, susceptibility to microorganisms) in their first days of life than those hatched in natural habitat, tha capacity of their immune response under farm conditions needs to be understood. Accordingly, we investigated such capacity using the blood of 10 clinical healthy, one-day old unsexed ostriches of the captive form of Struthio camelus. We found granulocyte fagocytic activity of 82.1%, granulocyte activity 0f 2.53%, granulocyte intracelular microbicidal capacity at 9.2%, monocyte fagocytic activity of 78.2%, monocyte activity of 1.35%, monocyte intracellular microbicidal activity at 33.4%, total leucocyte count at 7.6x10e9/L, percent heterofils of 85%, lymphocytes at 11.2%, eosinophils at 0.3%, monocytes at 2.6% and percent basophils at 0.9%. From this we conclude that determination of total differential leucocyte count and of fagocytic and monocytic activities provides appropriate diagnostic indication of the health status and immune response in one-day old ostriches. we expect that further investigations on larger sample sizes of ostriches will confirm this preliminary assessment.
