Primer reporte de Anaplasma phagocytophilum en Galápagos: alta prevalencia en perros y evidencia circunstancial del papel de Rhipicephalus linnaei como vector

Las Islas Galápagos albergan una biodiversidad única, pero también enfrentan amenazas relacionadas con enfermedades emergentes. Entre ellas, las transmitidas por garrapatas representan un riesgo tanto para la fauna local como para los animales domésticos. Dentro de este contexto, las bacterias del género Anaplasma son de especial interés por su capacidad de afectar la salud de los perros y su posible impacto en la fauna silvestre.

El propósito de este estudio fue determinar la presencia y prevalencia de especies de Anaplasma en perros de cuatro islas del Archipiélago de Galápagos (Santa Cruz, San Cristóbal, Florena e Isabela)  y evaluar el papel potencial de la garrapata Rhipicephalus linnaei como vector en la transmisión de estos patógenos.

En esta investigación se recolectaron muestras de sangre de 1.221 perros y se realizaron colectas de garrapatas para su identificación morfológica y genética. Los análisis moleculares evidenciaron una prevalencia significativa de Anaplasma phagocytophilum (20,3%), con mayor frecuencia en Santa Cruz (35,16%) e Isabela (18,9%). Además, se detectó A. platysen un 2,9% de las muestras. Los estudios genéticos confirmaron la presencia del ecotipo I de A. phagocytophilum, relacionado con cepas europeas, y señalaron a R. linnaei como la única especie de garrapata asociada a los perros.

Este trabajo representa la primera confirmación molecular de Anaplasma phagocytophilum y A. platys en perros de Galápagos, aportando información crucial sobre la epidemiología de las enfermedades transmitidas por garrapatas en la región. Los resultados evidencian la necesidad de fortalecer la vigilancia y aplicar medidas de control que reduzcan el riesgo de transmisión, protegiendo así tanto a la población local como a los animales domésticos, y la biodiversidad única del archipiélago.

In 2022, the Galapagos Science Center (GSC) and the broader UNC & USFQ Galapagos Initiative will celebrate its 10th Anniversary. We are proud to announce the World Summit on Island Sustainability scheduled to be held on June 26–30, 2022 at the Galapagos Science Center and the Community Convention Center on San Cristobal Island.

The content of the World Summit will be distributed globally through social media and results documented through papers published in a book written as part of the Galapagos Book Series by Springer Nature and edited by Steve Walsh (UNC) & Carlos Mena (USFQ) as well as Jill Stewart (UNC) and Juan Pablo Muñoz (GSC/USC). The book will be inclusive and accessible by the broader island community including scientists, managers, residents, tourists, and government and non-government organizations.

While the most obvious goal of organizing the World Summit on Island Sustainability is to celebrate the 10th Anniversary of the GSC and the UNC-USFQ Galapagos Initiative, other goals will be addressed through special opportunities created as part of our operational planning of the World Summit.

For instance, we seek to elevate and highlight the Galapagos in the island conservation discourse, seeking to interact with other island networks in more obvious and conspicuous ways to benefit the Galapagos Islands, the UNC-USFQ Galapagos Initiative, and the world. We will seize the opportunity to further develop the I2N2 – International Islands Network-of-Networks. Further, we wish to highlight and emphasize multiple visions of a sustainable future for the Galapagos Islands and we cannot do this alone. Therefore, engaging the Ecuadorian Ministry of Environment, the Ministry of Tourism, the Government Council of Galapagos, the Galapagos National Park, and local Galapagos authorities, including government and non-government organizations and local citizen groups, is imperative.

Borrowing from Hawaii’s and Guam’s Green Growth Program and the Global Island Partnership, we wish to examine existing global programs that emphasize island sustainability and their incorporation into life, policies, and circumstances in the Galapagos Islands. We will also seek to enhance our connections with the institutional members of our International Galapagos Science Consortium and expand the Consortium through the recruitment of other member institutions. We will also work to benefit islands and their local communities by working with citizen groups as well as important NGOs who seek to improve the natural conditions in the Galapagos and diminish the impact of the human dimension on the future of Galapagos’ ecosystems.

Lastly, we will use the World Summit to benefit UNC & USFQ and our constituencies through a strong and vibrant communication plan about the World Summit, creating corporate relationships as sponsors, identifying funding goals through donors, and benefiting our study abroad program for student engagement in the Galapagos Islands. We plan to develop and issue a Galapagos Sustainability Communique after the World Summit that includes the vision and insights of all its participants for a sustainable Galapagos with applicability to global island settings.

We are eager to hear your perspective and have you join us at the World Summit on Island Sustainability!
