Background: Myxozoans are widespread cnidarian parasites that mostly infect fish and annelids as temporary and definitive hosts, respectively [1]. Mullets are a diverse fish group, which ubiquitous nature leaves vulnerable to parasitic infections [2]. Objective: This study aimed to acknowledge the myxozoan diversity infecting thicklip grey mullet Chelon labrosus in the Douro River estuary in northern Portugal. ...
Background: Myxosporeans are important fish endoparasites with a complex life cycle that involves the production of actinospores in annelid hosts. More than 2,400 myxosporean species are presently known, yet only about 60 have their complete life cycle described [1]. Difficulties in the annelid sampling and examination, namely from the marine environment, and typically low prevalence of infection, hinder our kn...
