Laboratory analysis of innate American kestrel, Falco sparverius, immune response after exposure to flame retardant, isopropylphenyl phosphate (ITP) through 21 days post hatch. Data consist of flow cytometry files that were generated in the analysis of white blood cells from kestrel blood. Thus, data are in standard format that allows files created by one type of acquisition hardware and software to be analyzed by any other type.

This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, hatchling American kestrels (Falco sparverius) were exposed to the flame retardant isopropyl triphenyl phosphate (ITP) and then challenged with a synthetic analogue of viral double-stranded RNA, polyinosinic:polycytidylic acid (poly I:C). Control birds were challenged with vehicle only or vehicle and poly I:C. At euthanasia, spleen, thymus, and bursa of Fabricius were collected and fixed in 10% neutral buffered formalin for histopathological assessment. Slides were processed and stained with hematoxalin and eosin as per standard procedure (Luna 1968). Quantitative and qualitative B and T cell parameters were assessed by light microscopy. Specifically, variables assessed included the following: spleen: proportion of white to red pulp; thickness of peri-arteriolar lymphoid sheaths; number and diameter of lymphoid follicles; thymus: total area; area of medulla; density of cortical lymphocytes; number of tingible body macrophages; heterophil infiltration; bursa: follicular and medullary area; cellular density; apoptosis; heterophil infiltration; presence of follicular cysts. Evaluation of the architecture and cellular population of immune organs will shed light on potential functional immunological effects of exposure that may lead to increased susceptibility to infectious disease.

This work is part of a study of the immunological effects of exposure to alternative flame retardants in avian species. For the pathology portion of the study, spleens and bursas from American kestrels (Falco sparverius) exposed by egg injection to varying doses of short-chain chlorinated paraffins (SCCPs) and the flame retardant TBBPA-BDBPE were examined microscopically for architectural and cellular abnormalities. At euthanasia, spleen and bursa of Fabricius were collected and fixed in 10% neutral buffered formalin for histopathological assessment. Slides were processed and stained with hematoxalin and eosin as per standard procedure (Luna 1968). Quantitative and qualitative B and T cell parameters were assessed by light microscopy.

Evaluation of the architecture and cellular population of immune organs will shed light on potential functional immunological effects of exposure that may lead to increased susceptibility to infectious disease or affect normal growth and development of the chick.
