“…Because of their shape and general structure, eggs found in the present study resemble those of Paracapillaria malayensis and Capillostrongyloides arapaimae , differing from the former mainly in the polar plug, more irregular sculpture, size and host range (Moravec et al , 2007), and from the latter in the superficial net-like sculpture, size and host range (Santos et al , 2008). Additionally, egg shape and ornamentation are similar to those of eggs belonging to the genus Calodium , including C. hepaticum .…”

Numerous eggs of capillariid nematodes have been found in coprolites from a wide range of hosts and in raptor pellets in archaeological samples from Patagonia. The structure and sculpture of the eggshell of these nematodes and their biometry are commonly used for identification. The aim of this study was to determine whether eggs of the genus Calodium with similar morphology, found in different archaeological samples from Patagonia, belong to the same species. For this purpose, capillariid eggs (N= 843) with thick walls and radial striations were studied by permutational multivariate analysis of variance (PERMANOVA). Eggs exhibiting similar shape and structure also showed similar biometry, regardless of the zoological origin of coprolites (P= 0.84), host diet (P= 0.19), character of the archaeological sites (P= 0.67) and chronology (P= 0.66). Thus, they were attributed to the same species. We suggest that an unidentified zoonotic species of the genus Calodium occurred in the digestive tract of a wide range of hosts in Patagonia during the Holocene and that both human and animal populations were exposed to this parasite during the Holocene in the study area.

Third-stage larvae (L 3 ) of Hysterothylacium sp. were collected by the first time in juveniles of pirarucu Arapaima gigas farmed in the Rio Preto da Eva, Amazonas state. Ninety-eight (98) out of 100 examined fish showed to be parasitized. Five hundred and ninety larvae of Hysterothylacium sp. were collected from the intestines, stomach and pyloric caeca. The mean intensity of parasite indexes was 6.02 (±5.75) ranging from 1 to 40 larvae per host and the mean abundance was 5.9 (±5.76). The A. gigas is the new host record for larvae of Hysterothylacium sp. in Brazil, and this is the first record of larvae of Hysterothylacium (Nematoda: Anisakidae) with zoonotic potential in the pirarucu from South America.

“…The parasites were found free or penetrating the tissues mainly of the stomach but also the intestine of the fi sh, sometimes perforating the wall of these organs. Other nematodes of A. gigas in the area as Nilonema senticosum (Baylis, 1927), Rumai rumai Travassos, 1960, Camallanus tridentatus (Drasche, 1884 and Capillostrongyloides arapaimae Santos, Moravec et Venturieri, 2008 have been dealt with in our previous papers (Santos and Gibson 2007, Santos and Moravec 2009a. Goezia spinulosa is redescribed herein based on the examination of freshly collected material from wild and cultured arapaimas.…”

Abstract:The nematode Goezia spinulosa (Diesing, 1839) (Raphidascarididae) is redescribed based on specimens found in the stomach and intestine of the naturally infected arapaima Arapaima gigas (Schinz) from the Mexiana Island, Amazon River Delta, Brazil. Light and electron microscopy examinations revealed some previously unreported or inaccurately described morphological features in the species, such as the position of the excretory pore, phasmids in the male or the number (4) of postanal papillae. The morphology of G. spinulosa is compared with that of other four congeneric species parasitizing freshwater fi shes in South America. This nematode seems to be one of the most pathogenic parasites of A. gigas in the Mexiana Island, which are responsible for a high mortality of cultured arapaima fi ngerlings. Apparently, the source of G. spinulosa infection for arapaima fi ngerlings cultured in tanks was the infected plankton collected in the localities inhabited by wild arapaimas. Therefore, control measures should include the sterilisation of the plankton before its use as food for fi sh. A rare infection of Eustrongylides sp. larvae (Dioctophymatidae) in arapaima fi ngerlings was also found (new host record); the larvae were inside swellings on the body surface.
