En peces afectados con amebiasis branquial, se ha observado a nivel histol\u00f3gico una marcada hiperplasia epitelial y fusi\u00f3n lamelar, lo que a menudo conduce a una p\u00e9rdida de la arquitectura branquial con obliteraci\u00f3n de los espacios interlamelares.<\/p>\n\n\n\n

Varias especies de amebas pueden estar involucradas, algunas de ellas invadiendo el epitelio lamelar, pudiendo observar trofozoitos en peque\u00f1os grupos  dentro epitelio branquial como tambi\u00e9n sobre la superficie.<\/p>\n\n\n\n

Varios m\u00e9todos de diagn\u00f3sticos pueden ser utilizados para la detecci\u00f3n de amebas, entre ellos, frotis fresco, histopatolog\u00eda, aislamiento y cultivo, Hibridaci\u00f3n in situ<\/em> (ISH), microscop\u00eda electr\u00f3nica e inmunofluorescencia indirecta.<\/p>\n\n\n\n

En relaci\u00f3n al diagn\u00f3stico diferencial se puede mencionar a la Enfermedad Bacteriana de las Branquias (BGD – Bacterial Gill Disease), flavobacteriosis y micosis.<\/p>\n\n\n\n
