Abstract

Ulcerative and necrotizing dermatitis (UND) is a cutaneous disease caused by traumatic skin lesions on the necks of sea turtles. In this study we report the first findings of UND in free-ranging olive ridley turtles (Lepidochelys olivacea) in La Escobilla, Oaxaca, Mexico. We found several skin injury conditions on the necks of nesting turtles in the arribada events of the 2021 nesting season. Samples from injuries were taken with sterile swabs for bacteriological analyses, and antimicrobial resistance profiles were studied. Of the 525 turtles examined, 278 had injuries on the back of the neck (52.9% prevalence). Two bacteria (Pseudomonas sp. and Staphylococcus sp.) and 1 fungus (Candida sp.) were identified in 8 turtles with UND. Ciprofloxacin was the only antibiotic with high inhibition of Staphylococcus sp. and Pseudomonas sp. We recommend initiating a continuous monitoring program to follow the occurrence of dermatitis disease in L. olivacea in subsequent years to better document prevalence and progression of skin injuries in more individuals.

墨西哥瓦哈卡州拉埃斯科比拉橄榄蠵龟(Lepidochelys olivacea)中溃疡性和坏死性皮炎的首次发现

溃疡坏死性皮炎（UND）是一种由海龟颈部创伤性皮肤损伤引起的皮肤病。在这项研究中，我们报道了在墨西哥瓦哈卡州La Escobilla自由放养的橄榄脊龟（Lepidochelys olivacea）中首次发现UND。在2021筑巢季节的arribada事件中，我们在筑巢海龟的脖子上发现了几种皮肤损伤情况。用无菌拭子采集损伤样本进行细菌分析，并研究抗微生物耐药性。在检查的525只乌龟中，278只脖子后部受伤（患病率为52.9%）。在8只患有UND的海龟身上鉴定出2种细菌（假单胞菌属和葡萄球菌属）和1种真菌（念珠菌属）。环丙沙星是唯一对葡萄球菌和假单胞菌具有高度抑制作用的抗生素。我们建议启动一项持续监测计划，跟踪随后几年橄榄乳杆菌皮炎的发生情况，以更好地记录更多个体皮肤损伤的患病率和进展。

期刊介绍： A bilingual open-access publication, Ciencias Marinas (CM) is an international peer-reviewed journal that contains original research findings in all areas of marine science. It is published quarterly by the Autonomous University of Baja California, Mexico, and all its contents are publicly available on our journal website. Though a limited number of copies are still printed, the journal is mainly distributed in its electronic format. CM was conceived in 1973 as part of an academic project aimed to entice local researchers to publicly disclose their findings by adopting the culture of peer-review publishing. This academic project evolved into an international journal after accepting papers from researchers in the United States and, eventually, other parts of the world. Because of the diversity in authorship, CM issues were initially published in either Spanish or English, and occasionally in both languages. It was not until 1984 when CM included both language versions of all its contents, and it then became the fully bilingual journal it still is today. At CM we believe our inclusive format allows us not only to address a wider range of submissions from international authors but also to make published findings available to a wider international audience. So whether you are looking for information on the redfish in Icelandic waters or the physical and biological properties of the Gulf of California, feel free to peruse CM contents. You may find them to provide source material for your research.
