Pathogen Exposure Data for Chukchi Sea Polar Bears 1988-1994 and 2008-2017

This dataset is one table with results of tests to determine exposure of Chukchi Sea polar bears to a suite of pathogens. Results are serological tests for antibodies and tests of fecal samples for presence of parasites. Serologic assays were conducted for Toxoplasma gondii, Neospora caninum, Francisella tularensis, Coxiella burnetii, Leptospira spp., Brucella canis, Brucella abortus/suis, and canine distemper virus. Parasitology analyses were conducted for presence of Giardia cysts and Cryptospiridium oocysts in fecal samples. Polar bears were sampled on sea ice in the Chukchi Sea between mid-March and early May 1987-1994 and 2008-2017. The dataset includes relevant information about the bears that were captured including the latitude and longitude of their capture location, capture date, age and sex,and the age and number of cubs accompanying an adult female.

本数据集为单张数据表，收录了用于评估楚科奇海（Chukchi Sea）北极熊病原体暴露情况的检测结果。检测内容包括抗体血清学检测与粪便样本寄生虫筛查检测。本次血清学检测涵盖以下病原体：刚地弓形虫（Toxoplasma gondii）、犬新孢子虫（Neospora caninum）、土拉弗朗西斯菌（Francisella tularensis）、贝氏柯克斯体（Coxiella burnetii）、钩端螺旋体属（Leptospira spp.）、犬布鲁氏菌（Brucella canis）、流产布鲁氏菌/猪布鲁氏菌（Brucella abortus/suis）以及犬瘟热病毒（canine distemper virus）。寄生虫学分析则针对粪便样本中的贾第鞭毛虫包囊（Giardia cysts）与隐孢子虫卵囊（Cryptospiridium oocysts）开展检测。本次采样于1987-1994年及2008-2017年的3月中旬至5月初，在楚科奇海的海冰区域进行，采样对象为北极熊。本数据集收录了所有捕获个体的相关信息，具体包括捕获地点的经纬度、捕获日期、个体年龄与性别，以及成年雌性北极熊随行幼崽的年龄与数量。
