Abstract

Background: Tanygnathus lucionensis lucionensis, also known as the blue-naped parrot, is endemic to Luzon and Mindanao and is known for their distinctive blue crown and nape. Aims and Objectives: Being indigenous to the Philippines, the initial reports of hematological values and the common diseases of this subspecies are significant to be determined and studied. Materials and Methods: In this study, six captive blue-naped parrots at the Ninoy Aquino Parks and Wildlife Nature Center (NAPWNC) were tested to obtain initial reports for hematological parameters of the species. Using the ELISA method, the presence of Chlamydophila psittaci antibodies was determined to assure that there was no current infection. The study aimed to determine an initial report for the hematological values of the species and to detect the presence of antibodies against C. psittaci in the blood serum of blue-naped parrots held captive at the NAPWNC.
Results: The initial reports of the parameters were as follows: 6 3 Hematocrit is 44% ± 4%; total erythrocyte is 3.59 × 10 cells/mm ± 0.21; Hgb is 12.86 g/dL ± 1.12; mean corpuscular volume is 121 femtoliter ± 10; mean corpuscular hemoglobin (MCH) concentration is 29.75 % ± 3.62; MCH is 36.03 picogram ± 4.8; total 3 3 3 3 3 3 leukocyte is 17.95 x 10 cells/mm ± 2.84; total heterophil is 10.85 × 10 cells/mm ± 2.08; total basophil is 0.54 × 10 cells/mm 3 3 3 3 ± 0.38; total eosinophil is 0.15 × 10 cells/mm ± 0.18; total lymphocyte is 6.00 × 10 cells/mm ± 1.49; total monocyte is 0.4 × 3 3 3 3 10 cells/mm ± 10.41; and thrombocyte is 29.33 × 10 cells/mm ± 41.31. All of the six captive blue-naped parrots tested positive for the presence of C. psittaci antibodies indicating that the birds have been exposed to the bacteria but are not experiencing a current infection. Conclusion: The results of the hematological studies showed that these values for the blue-naped parrots do not differ from the close relative within the region. The significance of the absence of a current infection ensures validity of the initial hematological value reports obtained in this study.
