Lacaziosis-like disease among bottlenose dolphins Tursiops truncatus photographed in Golfo Dulce, Costa Rica

Abstract: Lacaziosis (also known as lobomycosis) is a chronic dermal disease caused by the fungal agent Lacazia loboi, which affects both humans and dolphins. Photographic data have been used to identify lacaziosis-like disease (LLD) among dolphins in the waters of North and South America, and here we report LLD in bottlenose dolphins Tursiops truncatus off the coast of Costa Rica, the first reporting in Central American waters. During the periods of 1991 to 1992 and 2010 to 2011, 3 research teams conducted separate dol… Show more

“…Small cetaceans have been used as bioindicators of bioaccumulative pollutants (Aguilar, 1984; Borrell et al ., 2004; Borrell & Aguilar, 2007; Lemos et al ., 2013) and are suitable as indicators for monitoring other natural or anthropogenic threats, specifically in areas heavily impacted by human activities. Examination of the injuries in wild cetaceans using photo-ID techniques (Evans & Hammond, 2004; Van Bressem et al ., 2007, 2015; Kiszka et al ., 2008; Murdoch et al ., 2008; Tetley et al ., 2012; Bessesen et al ., 2014; Sanino et al ., 2014; Hupman et al ., 2017) might provide good information on direct impact of potential threats on these animals (Hupman et al ., 2017). Vessel strikes, fishing entanglement and by-catch, or inter- and intra-species interactions can heavily impact small cetacean populations in coastal areas (Parsons & Jefferson, 2000).…”

“…Esta conducta refleja una respuesta ecológicamente dinámica del organismo ante los recursos disponibles y la estructura del hábitat (Gowans et al 2007), por lo que no solo se evidenciaría un uso del hábitat, sino también un proceso de selección que resulta del consumo intensivo (en su sentido más genérico) de recursos particulares que ofrece esta localidad discreta, en contraposición a lo disponible en toda la extensión del Golfo (Wheeler et al 2012). El traslape de áreas críticas de alimentación con la marina puede tener efectos significativos en esta población, ya que en esta misma área se han evidenciado afecciones dérmicas, en específico, la enfermedad denominada LLD (Lacaziosis Like Disease: Enfermedad Similar a Lacaziosis), de acuerdo con lo planteado en Bessesen et al (2014). Esta es una infección por hongos, que está relacionada con la degradación de condiciones ambientales, se estima que un cuadro previo de compromiso inmunotóxico por exposición a contaminantes, podría promover la morbilidad de esta enfermedad dérmica (Reif et al 2009), la cual afecta a especies de delfines costeros (Van Bressem et al…”

“…La alteración constante de conductas como alimentación, descanso y socialización repercute en funciones biológicas vitales (Constantine et al 2004;Lusseau, 2006;Lusseau et al 2009), resultando en impactos negativos del crecimiento poblacional (Lusseau, 2004;Bejder et al 2006). Se debe tomar en consideración que esta área ya evidencia individuos afectados con LLD (Bessesen et al 2014), por lo tanto, se esperaría que un hábitat con mayor perturbación de la actual podría incrementar la progresión de la enfermedad en número de delfines afectados y evolución crónica de la micosis en estos.…”

“…In 2010 and 2011, on-water sighting surveys were undertaken and interviews with local fishermen and tour boat guides were conducted to collect baseline data on a range of marine vertebrates that utilize Golfo Dulce as part of their natural ecology. The breadth of our findings is presented here; some previously published data (Bessesen, 2012;Bessesen & Saborío, 2012;Bessesen et al, 2014) are included to provide a comprehensive and comparative view. Distribution patterns in particular should serve to stress the importance of maintaining Golfo Dulce in healthy condition.…”
