Abstract

espanolLa fibropapilomatosis (FP) es una enfermedad neoplasica que afecta a las tortugas marinas en aguas tropicales. Los individuos juveniles de tortuga verde (Chelonia mydas) parecen ser los mas afectados por los tumores cutaneos, que no son malignos, pero dependiendo de su numero, tamano y ubicacion, pueden comprometer la supervivencia. La prevalencia de la FP en tortugas marinas ha incrementado en las decadas pasadas en zonas como Espirito Santo (Brasil) y Texas (EUA), pero en Mexico pocos casos han sido documentados a la fecha. Durante 2017–2018 se registro por primera vez una prevalencia de FP del 12.2% en tortugas de vida libre en el Parque Nacional Sistema Arrecifal Veracruzano, un area sujeta a la presion ambiental y la presion antropica. De acuerdo con el analisis histopatologico de una muestra de tejido, los tumores fueron consistentes con las caracteristicas de fibropapilomas. Los tumores no fueron severos (0.01–7.16 cm), pero la mayoria tuvo una apariencia verrugosa y se encontraron en las aletas y los ojos, lo que podria representar un riesgo potencial para la salud de los juveniles. Se recomienda continuar el monitoreo de esta poblacion, y la informacion aportada aqui puede servir de base para estudios futuros en aguas mexicanas del golfo de Mexico, en donde la FP no habia sido reportada aun.

墨西哥韦拉克鲁斯中部海岸自由放养的绿海龟(Chelonia mydas)的纤维乳头状瘤病

西班牙纤维乳头状瘤病（FP）是一种影响热带水域海龟的肿瘤性疾病。绿海龟（Chelonia mydas）的幼年个体似乎受到皮肤肿瘤的影响最严重，这些肿瘤不是恶性的，但根据它们的数量、大小和位置，它们可能会损害生存。在过去的几十年里，在Espirito Santo（巴西）和Texas（美国）等地区，海龟中的FP患病率有所上升，但在墨西哥，迄今为止很少有病例有记录。2017-2018年，在受环境压力和人为压力影响的地区，Arrecifal Veracruzano系统国家公园，自由生活海龟的FP患病率首次达到12.2%。根据对组织样本的组织病理学分析，肿瘤与纤维乳头状瘤的特征一致。肿瘤并不严重（0.01-7.16厘米），但大多数呈疣状，出现在鳍和眼睛中，这可能对青少年的健康构成潜在风险。建议继续监测这一人群，这里提供的信息可作为未来在墨西哥湾墨西哥水域进行研究的基础，墨西哥湾的FP尚未报告。英国纤维乳头状瘤病（FP）是一种影响热带地区海龟的肿瘤性疾病。幼年绿海龟（Chelonia mydas）似乎是受皮肤肿瘤影响最严重的海龟，这些肿瘤不是恶性的，但取决于它们的数量、大小和位置，可能会阻碍生存。在过去的几十年里，在埃斯皮里托·桑托（巴西）和德克萨斯州（美国）等地区，海龟的FP流行率有所上升，但在墨西哥，到目前为止，很少有病例得到记录。在这里，我们报告说，2017-2018年在韦拉克鲁斯珊瑚礁系统国家公园捕获的自由放养海龟中，FP患病率为12.2%，这是墨西哥以前未报告的地点，受到环境和人为压力。对发现的一个组织样本的组织病理学分析与纤维乳头瘤的特征一致。它们并不严重（0.01-7.16厘米），但大多数有疣状外观，主要发现在脚蹼和眼睛上，可能对幼龟的健康有害。我们建议继续监测这一人口，这里提供的信息可以作为墨西哥湾这一尚未报告FP的地区未来研究的基线。

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.
