Xanthochromism (also called xanthochroism or xanthism), from the Greek xanthos (ξανθός) "yellow" and chroma (χρώμα) "color", is an unusually yellow pigmentation in an animal. It is often associated with the lack of usual red pigmentation and its replacement with yellow.

2024年3月1日 · Xanthochromia is the observation of a yellowish discoloration in cerebrospinal fluid (CSF) attributed to the presence of bilirubin. This yellow hue, linked with various pigmented compounds from red blood cell breakdown, signifies conditions ranging from jaundice and high CSF protein to aneurysmal and nonaneurysmal subarachnoid hemorrhage.

Xanthochromia, from the Greek xanthos (ξανθός) "yellow" and chroma (χρώμα) "colour", is the yellowish appearance of cerebrospinal fluid that occurs several hours after bleeding into the subarachnoid space caused by certain medical conditions, most commonly subarachnoid hemorrhage. [1] .

What is Bird Xanthochromism? Bird Xanthochromism is a genetic mutation that results in excessive production of yellow pigment. This mutation is, in reality, related to the lack of production of the color red, which is replaced with yellow. Xanthochromic birds can have the bill and bare parts of the normal color or yellowish.

2023年7月6日 · Xanthochromia refers to the yellowish discoloration of body fluids, most commonly observed in cerebrospinal fluid (CSF) and ocular fluids. This discoloration is attributed to the presence of bilirubin breakdown products and is often associated with underlying pathological conditions.

This color change is attributed to varying concentrations of pigmented compounds such as oxyhemoglobin, bilirubin, and methemoglob …

2020年2月21日 · This unique cardinal, aptly nicknamed “Sunny,” gets its yellow coloration from a genetic mutation called xanthochromism, which is similar to albinism. This mutation knocked out, or shut off, the redness pathway in the bird’s DNA, blocking the normal red coloring and causing an excessive production of yellow pigment.

Another common discoloration is xanthochromia, in which the fluid is yellow and clear. This discoloration may appear following hemorrhage into the arachnoid space and is probably due to the presence of free bilirubin resulting from the chemical breakdown of heme in the spinal canal.

2021年7月28日 · An assessment of the global archive showed that numerous levels of abnormal xanthochromism have been defined in at least 63 species of fish in the wild, embracing a diversity of taxonomic groups in both marine and freshwater environments, comprising 3 agnathans, 6 chondrichthyans, and 54 Teleosts (Quigley et al. 2017).
