Gregarines are a common group of parasites that infect the intestines of marine invertebrates, and particularly polychaetes. Here, we describe for the first time four gregarine species that inhabit the intestines of three spionid species: Dipolydora cf. flava, Spio quadrisetosa and Boccardia proboscidea from the Patagonian coast, Argentina, using light and scanning electron microscopy and molecular phylogenetic analyses of small subunit (SSU) rDNA sequences. Even though the spionid species thrive ...

Histopathology associated with the apicomplexan Aggregata valdessensis in the wild population of Octopus tehuelchus was studied. Moreover, to analyze the impact of the prevalence and infection intensity on the dorsal mantle length, sex, maturity stages, condition index and total hemocyte counts on wild O. tehuelchus, Generalized Linear Models (GLMs) were applied. Kruskal–Wallis (KW) test was used to compare growth parameter (RNA/DNA ratios) in infected and uninfected octopuses. Lesions including hypertrophy ...

Histolopathology associated with the apicomplexan Aggregata valdessensis on wild population of Octopus tehuelchus was studied. Moreover, to analyze the impact of the prevalence and infection intensity on the size, sex, maturity stages, condition index and total hemocyte counts on wild O. tehuelchus, Generalized Linear Models (GLMs) were applied. Kruskal–Wallis (KW) test was used to compare growth parameter (RNA/DNA ratios) in infected and no infected octopuses. Lesions including hypertrophy of host ...
