Immature Polyacanthorhynchus rhopalorhynchus (Acanthocephala: Polyacanthorhynchidae) in Venton, Hoplias malabaricus (Pisces) from Moca Vie River, Bolivia, with Notes on its Apical Organ and Histopathology

چکیده
Cystacanths of Polyacanthorhynchus rhopalorhynchus (Diesing, 1851) Travassos, 1920 were discovered in the viscera of venton, Hoplias malabaricus (Bloch, 1794) collected from the Moca Vie River at Las Palquitas, Bolivia. Apical proboscis organ and general morphological features were similar to but less developed than those of Polyacanthorhynchus kenyensis Schmidt and Canaris, 1967 cystacanths from Africa. Cystacanths of P. rhopalorhynchus were not deeply embedded in liver tissue. A collagenous connective tissue capsule surrounded and attached the cystacanths to the liver surface. Necrosis of hepatocytes and subsequent inflammatory response were observed near encapsulated acanthocephalans. Cystacanths attached to the intestine were encapsulated in the fibroserosa.

We analyzed 54 specimens of Hoplias aff. malabaricus (Bloch, 1794) collected between March 2010 and March 2011 from the upper Paraná river Neotropical floodplain, Brazil. All hosts were parasitized by at least one species of Monogenea. The parasites species with higher prevalence were Urocleidoides cuiabai Rosim, Mendoza-Franco & Luque, 2011 (96.29 %) and U. malabaricusi Rosim, Mendoza-Franco &...

Hoplias malabaricus (Bloch, 1794), a predatory freshwater fish with a wide distribution throughout South America, represents a species complex with seven well characterized karyomorphs at the cytogenetic level. Although this species has been extensively studied in several Brazilian basins, data are still scarce for hydrographic systems from other South American countries. This study aims to cha...

Erythrinidae include Neotropical teleost fish that are widely distributed in South America. Hoplias Gill, 1903 include two large groups: H. malabaricus Bloch, 1794 and H. lacerdae Miranda Ribeiro, 1908. Hoplias malabaricus is characterized by remarkable karyotype diversity, with some karyomorphs widely distributed geographically while others are more restricted to certain river basins. Cytogene...
