Protozoal diversity in the forestomach of South American camelids (SAC) was studied in eight llamas and six alpacas from the Parque Natural Condoriri (3900 to 4100 m altitude, Departamento La Paz, Bolivia). Total protozoal concentrations were 3.6 times higher (P < 0.001) in the stomach contents of alpacas (39.6 x 10 4 ml -1 and 143.8 x 10 4 ml -1 in llamas and alpacas, respectively). Four to 11 species, all from the genus Entodinium, were observed in llamas, whereas from eight to nine species of Entodinium and minor proportions of Diplodinium (D. anisacanthum, D. dogieli, D. rangiferi), Eudiplodinium (E. bovis, E. maggii, E. neglectum) and Epidinium (E. ecaudatum) were observed in alpacas. The presence of Epidinium species in the alpaca is a new host record. The vestibuliferids, Dasytricha and Isotricha were absent from the forestomach of SAC, as well as other species such as Caloscolex genus, Diplodinium cameli and Entodinium ovumrajae, commonly found in Old World camelids.

New Host Record

Pojmanskia riosae (Digenea: Leucochloridiidae) and Lubens lubens (Digenea: Dicrocoeliidae) are described from the intestine and cloaca of the Chororó or Great Antshrike, Taraba major (Passeriformes: Thamnophilidae) from Formosa Province, Argentina. The finding of P. riosae constitutes the first record of the genus for South American birds and the first record in thamnophilid birds. The discovery of L. lubens in T. major represents a new host record and the first report of this species in Argentina. Moreover, Lubens phelpsi is synonymized with L. lubens.

Sarcocyst Wall

SUMMARYThere is considerable confusion concerning the species of Sarcocystis in South American camelids (SAC). Several species names have been used; however, proper descriptions are lacking. In the present paper, we redescribe the macroscopic sarcocyst forming Sarcocystis aucheniae and describe and propose a new name, Sarcocystis masoni for the microscopic sarcocyst forming species. Muscles samples were obtained from llamas (Lama glama) and guanacos (Lama guanicoe) from Argentina and from alpacas (Vicugna pacos) and llamas from Peru. Individual sarcocysts were processed by optical and electron microscopy, and molecular studies. Microscopic sarcocysts of S. masoni were up to 800 µm long and 35–95 µm wide, the sarcocyst wall was 2·5–3·5 µm thick, and had conical to cylindrical villar protrusions (vp) with several microtubules. Each vp had 11 or more rows of knob-like projections. Seven 18S rRNA gene sequences obtained from sarcocysts revealed 95–96% identity with other Sarcocystis spp. sequences reported in the GenBank. Sarcocysts of S. aucheniae were macroscopic, up to 1·2 cm long and surrounded by a dense and laminar 50 µm thick secondary cyst wall. The sarcocyst wall was up to 10 µm thick, and had branched vp, appearing like cauliflower. Comparison of the 11 sequences obtained from individual macroscopic cysts evidenced a 98–99% of sequence homology with other S. aucheniae sequences. In conclusion, 2 morphologically and molecularly different Sarcocystis species, S. masoni (microscopic cysts) and S. aucheniae (macroscopic cysts), were identified affecting different SAC from Argentina and Peru.

Ciliate Protozoa

The forestomach contents of 20 dromedary camels were examined for total, generic and species composition of ciliate protozoa. The geometric mean value of total ciliate protozoa was 13.9 X 10 4 / ml with values ranging from 4.9 to 109.4 X 10 4 / ml. A total of ten genera containing 31 species and 16 forms were identified. Five species of Entodinium (E. biconcavum, E. bimastus, E. ekendrae, E. parvum and E. tsunodai) and Ostracodinium trivesticulatum represent a new host record. Two new spinated forms of Diplodinium cameli were observed, one has a single spine arising from the left lateral surface near the posterior end and the second has an additional spine on the posterior right lateral surface. Previous reports on concentration and species composition in the camel are summarized and compared to the present results.

Acanthocephalan Parasite

A cyprinid, the Prussian carp (Carassius gibelio (Bloch, 1782)), has become an established invasive fish in several watersheds in Alberta, Canada. Originating in Eurasia, Prussian carp negatively impact native fish through predation, competition, and habitat modification. Prior to this study, nothing was known regarding the external and internal parasites of these fish in North America, although nine studies had been conducted in Europe and Asia. We examined 22 fish (20 female, 2 male) ranging from 3 to 5 years of age and recorded morphological features, stomach contents, and performed standard necropsy examinations for parasites. One parasite species, the acanthocephalan Pomphorhynchus bulbocolli Linkins in Van Cleave, 1919, was found in three fish (14%), with a mean intensity of 1.0. This is a new host record and the first report of any acanthocephalan parasite in Prussian carp. We conclude that Prussian carp are not introducing any novel parasites into native fish and that they are resistant to most infections by native parasites.

AbstractParagordius is a genus of Gordiida with a worldwide distribution, but with a scarce specific diversity. Sixteen species of the genus Paragordius have been described so far. In many cases, as with the other genera of Gordiida, the original descriptions of the species are insufficient due to the limitations of the techniques employed. In this work the holotypes of P. minusculus and P. esavianus are redescribed by scanning electron microscopy (SEM), a new species of Paragordius is described, the distribution for P. esavianus and P. varius is enlarged and a new host record of P. esavianus is presented.

AbstractOswaldofilaria acanthosauri sp. nov. from the body cavity of the Cardamom Mountain horned agamid, Acanthosaura cardamomensis (Sauria: Agamidae), collected in Pursat Province, Cambodia is described. Of the 14 species assigned to Oswaldofilaria, O. acanthosauri sp. nov. is most similar to those species with spicular ratio of less than 2, namely, O. brevicaudata and O. chlamydosauri. Oswaldofilaria acanthosauri sp. nov. is easily separated from these 2 species in that O. brevicaudata is a South American species and in O. chlamydosauri the distal ends of the spicules are pointed not blunt. Mature individuals of 2 additional species of Nematoda, Meteterakis singaporensis and Orneoascaris sandoshami, as well as larvae assignable to Ascariidae were found. Acanthosaura cardamomensis represents a new host record for Meteterakis singaporensis, Orneoascaris sandoshami and Ascariidae (larvae).

New Host Record

A novel species, Micropeltis goniothalamicola and a new record Scolecopeltidium menglaense were collected from Mae Fah Luang Botanical Gardens, Thailand. Our new taxon is different from other species in Micropeltis in having relatively smaller ascomata, 6–8-spored asci and 4–5-septate ascospores covering with mucilaginous sheath. Our new record, S. menglaense is the first host recorded from Jasmine grandiflorum (Oleaceae). Morphological comparison coupled with phylogenetic analysis of combined LSU and ITS sequence data provide evidence for the new species and new host record.
