摘要

在衰弱、搁浅和死亡的绿海龟(Chelonia mydas)身上发现了阳性血液培养物,这表明绿海龟患有败血症。对这些结果的解释往往很困难,因为之前有多项研究发现临床健康的爬行动物体内存在菌血症。本研究从佛罗里达州卡纳维拉尔港的 50 只未成年散养绿海龟身上采集了成对的血液培养物和静脉穿刺部位无菌准备后获得的皮肤培养物。将血液培养结果与健康状况(根据体格检查结果和适当的身体状况,看似健康或不健康)、采集日期、是否存在外部纤维肉瘤病、已愈合或未愈合的损伤以及是否存在藤壶进行了比较。比较血培养阳性龟和血培养阴性龟的体重、身体状况评分、身体状况指数、形态测量、采血量和体温。在所有乌龟中,有 14%(50 只中有 7 只)的乌龟血液培养呈阳性,其中包括 15.6%(32 只中有 5 只)表面健康的乌龟。从表面健康的个体血液培养物中分离出了弧菌属、巨大芽孢杆菌、纤维单胞菌和巴氏葡萄球菌。皮肤培养阳性和血液培养阳性之间有明显的关联(P = 0.048),但在配对结果中分离到的菌株始终不同。血液培养结果与健康状况、痊愈或未痊愈的伤痕、外生殖器纤维瘤病或藤壶的存在之间没有明显关联(P > 0.05)。根据这项研究的结果,表面上健康的绿海龟可能会出现血液培养阳性,提示非临床菌血症。这项研究的结果将有助于临床医生解释表面健康或假定患有败血症的人工饲养绿海龟和康复绿海龟的血液培养结果,这也是这一濒危物种的保护和种群恢复工作的一部分。

AEROBIC BLOOD CULTURES AND COMPARISON TO CLINICAL FINDINGS OF FREE-RANGING GREEN TURTLES (CHELONIA MYDAS) IN EAST CENTRAL FLORIDA.

Positive blood cultures have been identified in debilitated, stranded, and deceased green turtles (Chelonia mydas), suggestive of septicemia. Interpretation of these results is often difficult because multiple studies have previously identified bacteremia in clinically healthy reptiles. In this study, paired blood cultures and skin cultures obtained after aseptic preparation of the venipuncture site were collected from 50 immature free-ranging green turtles from Port Canaveral, Florida. Blood culture results were compared with health status (apparently healthy versus unhealthy, based on physical examination findings and appropriate body condition), date of collection, presence of external fibropapillomatosis, healed or unhealed injuries, and presence of barnacles. Weight, body condition score, body condition index, morphometric measures, volume of blood collected, and body temperature were compared between blood culture-positive and blood culture-negative turtles. Positive blood cultures were identified in 14% (7 of 50) of all turtles, including 15.6% (5 of 32) of apparently healthy turtles. Vibrio spp., Bacillus megaterium, Cellulomonas sp., and Staphylococcus pasteuri were isolated in blood culture from apparently healthy individuals. There was a significant association (P = 0.048) between positive skin cultures and positive blood cultures, but isolates obtained were consistently different between paired results. There was no significant association (P > 0.05) between blood culture results and health status, evidence of healed or unhealed injuries, external fibropapillomatosis, or presence of barnacles. Based on the results of this study, positive blood cultures suggestive of nonclinical bacteremia may be present in apparently healthy green turtles. The results of this study will aid the attending clinician in interpretation of blood culture results of apparently healthy or presumed septicemic captive and rehabilitating green turtles as part of the conservation and population recovery of this threatened species.

期刊介绍: The Journal of Zoo and Wildlife Medicine (JZWM) is considered one of the major sources of information on the biology and veterinary aspects in the field. It stems from the founding premise of AAZV to share zoo animal medicine experiences. The Journal evolved from the long history of members producing case reports and the increased publication of free-ranging wildlife papers. The Journal accepts manuscripts of original research findings, case reports in the field of veterinary medicine dealing with captive and free-ranging wild animals, brief communications regarding clinical or research observations that may warrant publication. It also publishes and encourages submission of relevant editorials, reviews, special reports, clinical challenges, abstracts of selected articles and book reviews. The Journal is published quarterly, is peer reviewed, is indexed by the major abstracting services, and is international in scope and distribution. Areas of interest include clinical medicine, surgery, anatomy, radiology, physiology, reproduction, nutrition, parasitology, microbiology, immunology, pathology (including infectious diseases and clinical pathology), toxicology, pharmacology, and epidemiology.
