The Histopathology of the Infection of Tilapia rendalli and Hypostomus regani (Osteichthyes) by Lasidium Larvae of Anodontites trapesialis (Mollusca, Bivalvia)
It is described the histopathology of the infection of Tilapia rendalli (Osteichthyes, Perciformes, Cichlidae) and Hypostomus regani (Osteichthyes, Siluriformes, Loricariidae) by lasidium larvae of Anodontites trapesialis (Mollusca, Bivalvia, Mycetopodidae). The larvae were encysted within the epide...
