- Trichodina mutabilis (Protozoa: Ciliophora: Trichodinidae) from the characid fish Astyanax mexicanus in the Cuatro Ciénegas region, northern Mexico Alma Gabriela Islas-Ortega Rogelio Aguilar-Aguilar Biología ecto ciliates parasitism Trichodinidae As a part of a series of ongoing studies on trichodinids of freshwater fishes of Mexico, several species from diverse localities in the Cuatro Ciénegas region, Coahuila, northern Mexico, were examined. Wet smears of gills and skin were made fresh and screened for the presence of trichodinids under light microscopy. Additional specimens were fixed for SEM. The only trichodinid species found was Trichodina mutabilis, a parasite of the characid fish Astyanax mexicanus. This ciliate protozoan has been introduced from Asia to many countries, including Mexico, with its original host, the Asian carps. The present record is the first for Mexico and the second in North America, being the first record of a Trichodina species for native wild freshwater fish in a natural environment in Mexico, since all previous records were from exotic cultured fishes. 2014 artículo científico 1870-3453 https://www.redalyc.org/articulo.oa?id=42531364018 en http://www.redalyc.org/revista.oa?id=425 Revista Mexicana de Biodiversidad application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Biodiversidad (México) Num.2 Vol.85
