Análisis fúngico marino y potencial patógeno sobre el delfín mular Tursiops truncatus en el estero El Morro, Guayas-Ecuador. //Marine fungal analysis and pathogenic potential of the bottlenose dolphin Tursiops truncatus estero El Morro, Guayas-Ecuado
'Universidad Estatal de Milagro (UNEMI)', 2019Co-Authors: Hernadez-tapia FranciscaAbstract:El turismo generado por la observación de delfines mular Tursiops truncatus es una de los principales atractivos turísticos en el estero El Morro, Guayas-Ecuador, sin embargo, la falta de caracterización de hongos en el medio acuático como fuentes principales infecciosas en Tursiops truncatus, genera preocupación sobre esta población, ante esto es necesario la caracterización fúngica del medio acuático en el estero El Morro. Para tal fin, se colectaron muestras de agua durante los meses enero y febrero de 2016, para realizar cultivos de hongos en Agar Sabouraud con dextrosa a temperatura de 30˚C por tres días; posteriormente, se realizó aislados de cepas para identificación morfológica y molecular. La identificación morfológica determinó 17.50% de especies como potencial agente patógeno, entre ellas Aspergillus fumigatus, Blastomyces dermatitidis y Candida albicans. A través del análisis molecular mediante la sección del espaciador interno transcripto ITS [Internal Transcribed Spacer (ITS)] se identificó a Rhizopus oryzae, especie reportada como agente causal de infección en delfines. Aunque se detectó Aspergillus carbonarius y Heteroacanthella acanthothysa, estas especies no están catalogadas como agentes patógenos para delfines. Este estudio permite concluir que parte de la diversidad fúngica del agua del estero El Morro representa un potencial riesgo para la salud de los delfines que habitan esta zona. AbstractThe tourism generated by the observation of bottlenose dolphins Tursiops truncatus is one of the main tourist attractions in the El Morro estuary, Guayas-Ecuador. However, the lack of characterization of fungi in the aquatic environment as main infectious sources in Tursiops truncatus, generates concern about this population, before this is necessary the fungal characterization of the aquatic environment in the El Morro estuary. For this purpose, water samples were collected during the months of January and February 2016, to culture fungi in Sabouraud Agar with dextrose at 30˚C temperature for three days; later, isolates of strains were made for morphological and molecular identification. The morphological identification determined 17.50% of species as potential pathogenic agent, among them Aspergillus fumigatus, Blastomyces dermatitidis and Candida albicans. Through molecular analysis using the Internal Transcribed Spacer (ITS) section, Rhizopus oryzae, a species reported as a causative agent of infection in dolphins, was identified. Although Aspergillus carbonarius and Heteroacanthella acanthothysa were detected, these species are not catalogued as dolphin pathogens. This study allows to conclude that part of the fungal diversity of the water of the El Morro estuary, which represents a potential risk to the health of the dolphins that inhabit this area.

hybridization in the wild between Tursiops truncatus montagu 1821 and delphinus delphis linnaeus 1758
PLOS ONE, 2019Co-Authors: Rocio Espada, Liliana Olayaponzone, Luisa Haasova, Estefania Martin, J C GarciagomezAbstract:A case of intergeneric hybridization in the wild between a female bottlenose dolphin (Tursiops truncatus) and a short-beaked common dolphin (Delphinus delphis), considered members of 'vulnerable' and 'endangered' subpopulations in the Mediterranean, respectively, by the International Union of Conservation of Nature is described in this paper. The birth of the hybrid was registered in the Bay of Algeciras (southern Spain) in August 2016, and the animal has been tracked on frequent trips aboard dolphin-watching platforms. This unique occurrence is the result of an apparent ongoing interaction (10 years) between a female bottlenose dolphin and common dolphins. The calf has a robust body with length similar to Tursiops, while its lateral striping and coloration are typical of Delphinus. It displays the common dolphin's 'criss-cross' pattern. However, the thoracic patch is lighter than in D. delphis and its dorsal area is light grey, with a 'V' shape under the dorsal fin. This paper also provides a comprehensive mini-review of hybridizations of T. truncatus with other species.
