Abstract
This study describes a case of Calodium hepaticum (Trichinellida: Capillariidae) infection in an adult rat (Rattus rattus) from the periurban area of the city of La Plata in the province of Buenos Aires, Argentina. The rat was found with neurological signs (ataxia, lethargy, and episodes of unresponsiveness) in the food storage of a goat production facility. The liver was observed with hepatomegaly and diffuse and irregular yellowish-white spots appearing in striae or small nodules on the external surface and inside the liver. Subsequent microscopic and histopathological studies were performed. Eggs were observed by direct microscopy of the impression smear of liver tissue. A multifocal granulomatous tissue reaction with different stages of fibrocellular tissue was observed in the liver parenchyma. The granulomas contained adults and degenerated eggs delimited by an intense infiltrate of mononuclear cells. Macro and microscopic observations and histopathological liver lesions were compatible with C. hepaticum infection. To our knowledge, this is the first confirmation of C. hepaticum infection in R. rattus in Argentina, increasing the host record of this parasite and a new record of distribution in goat production systems in the country.

Abstract
Calodium hepaticum (syn. Capillaria hepatica) is a nematode responsible for parasitic zoonosis that can cause granulomatous lesions in the liver. Although murids are the main hosts, C. hepaticum has been documented in a wide range of mammals. Here, we report a case of hepatic calodiosis in a 6-month-old dog that was rescued in the municipality of Cuiabá, Mato Grosso state, midwestern Brazil. Even after being attended at a Veterinary Hospital, the case resulted in animal death. Necroscopic examination revealed significant macroscopic changes in the spleen, liver, and encephalus. Microscopic examination revealed parasitic eggs, identified as Calodium cf. hepaticum, that were rounded to oval with a bilamellar cuticle, radially striated, and with bipolar plugs. Considering the difficulty to diagnose this parasite, and the existence of diverse possible hosts in Mato Grosso due to the biodiversity of the state, further investigation is required to understand the true prevalence of C. hepaticum and the importance of this nematode in public health.

Abstract
Gastrointestinal parasites are well-documented in small mammals from north-central Chile, but little is known about endoparasites of rodents in southern Chile. A survey was conducted between January and February 2018 to evaluate gastrointestinal parasites and risk factors of wild rodents that live in rural areas in Northern Chiloé Island, Chile. A total of 174 fecal samples from rodents of six native and one introduced species were collected and examined using the Mini-FLOTAC method. Also, 41 individuals of four native wild rodent species were examined furtherly to determinate adult parasites from gastrointestinal tracts. The overall prevalence of endoparasites was 89.65% (156). Helminth egg types included: Rodentolepis spp., Capillariidae, Trichuris sp., Syphacia sp., oxyurid-type eggs, Strongyloides sp., Spirurid-type eggs, Strongilid-type eggs, Moniliformis sp., and an unidentified nematode egg and larvae. Protozoa comprised coccidia, amoeba, and unidentified cysts. From necropsies, adult parasites involved Syphacia sp. Trichuris sp., Protospirura sp. and Physaloptera sp. In Abrothrix olivacea, individuals with low-body-mass index exhibited reduced infection probability for Spirurid-type and Strongilid-type eggs. Some parasites in this study may affect human health. In rural settings where environmental conditions are changing, more research should be undertaken to understand parasitic infections in wildlife and implications for public health and conservation.

Abstract
Calodium hepaticum is a zoonotic nematode with a worldwide distribution. Although the host range of C. hepaticum includes a wide spectrum of mammals (including humans), this parasite is predominantly associated with the families Muridae and Cricetidae. Several Sigmodontinae species from Argentina were found to be infected by C. hepaticum, with a high prevalence in Akodon azarae. The present study focuses on C. hepaticum eggs from natural infection of three species of sigmodontine rodents from Argentina. Eggs were genetically characterized (intergenic 18S rRNA region). The objectives of this work are: (i) to propose a new analytical methodology; and (ii) to morphologically characterize C. hepaticum eggs, from three Sigmodontinae species (A. azarae, Calomys callidus and Oligoryzomys flavescens). Analyses were made by the Computer Image Analysis System based on the new standardized measurements and geometric morphometric tools. The resulting factor maps clearly illustrate global size differences in the parasite eggs from the three Sigmodontinae species analysed. The degree of similarity between egg populations was assessed through pairwise Mahalanobis distances, showing that the largest distances were detected between parasite eggs from C. callidus and O. flavescens. Herein, the phenotypical plasticity of C. hepaticum eggs is shown. Significant positive correlations were obtained between each egg parasite principal component 1 and rodent corporal characteristics: weight; liver weight; rodent length; and rodent body condition. The usefulness of the geometric morphometric analysis in studies of the relationship between C. hepaticum and its host must be highlighted. The high prevalence observed in A. azarae, associated with the wide size range of the parasite eggs evidenced by principal component analysis, suggests A. azarae to be the Sigmodontinae host species that plays the most important role as reservoir host for C. hepaticum in the New World.

Abstract
Calodium hepaticum (Bancroft, 1893) Moravec, 1982 (Syn. Capillaria hepatica) is a zoonotic nematode that causes hepatic capillariosis, an uncommon zoonotic infection. The nematode is globally distributed and parasitizes the liver of mammals, mainly Muroidea. Cricetulus migratorius Pallas, 1773 (Cricetinae) was rarely reported as a host for C. hepaticum. In Turkey, C. hepaticum was recorded in three rodent species; Rattus rattus, R. norvegicus, and Apodemus flavicollis. In this study, C. migratorius (grey dwarf hamster) has been identified as a new host species for C. hepaticum in Turkey. The parasite was identified by morphological, histological, and molecular methods and the phylogenetic relationships of C. hepaticum collected from different hosts were revealed. This is the first molecular characterization of C. hepaticum from a grey dwarf hamster.

Integrated taxonomic approaches to seven species of capillariid nematodes (Nematoda: Trichocephalida: Trichinelloidea) in poultry from Japan and Indonesia, with special reference to their 18S rDNA phylogenetic relationships. Parasitol Res 2019; 119:957-972.

Abstract
Morphological and genetic analyses were performed on seven species of the family Capillariidae (Nematoda: Trichocephalida: Trichinelloidea), viz. Eucoleus perforans, Eucoleus contortus, Aonchotheca bursata, Baruscapillaria obsignata, Capillaria anatis, Capillaria phasianina, and Capillaria spinulosa, detected in poultry from Japan and Indonesia. Two Eucoleus spp., perforating the esophageal mucosa of the Japanese green pheasant farmed in Japan (E. perforans) and domestic goose in Indonesia (E. contortus), were morphologically characterized. Furthermore, we observed substantial nucleotide differences between their 18S ribosomal RNA gene (rDNA), revealing maximum identity (97.27%) over the 1797-bp length. Similarly, B. obsignata in the small intestine of Japanese green pheasants in Japan, a chicken, geese, domestic pigeons, and a turkey in Indonesia, and C. anatis in the ceca of chickens in Indonesia were morphologically and molecular-genetically compared with previously reported isolates of these species in Japan. Aonchotheca bursata collected from the small intestine of the Japanese green pheasant was also molecular-genetically characterized for the first time; however, sequencing of the 18S rDNA of C. phasianina from the cecum of the same bird was unsuccessful. Capillaria worms in the ceca of a domestic duck and geese in Indonesia were identified as C. spinulosa, which had only previously been recorded in wild birds of the Anseriformes in the Palaearctic region. Morphologically, this species was closest to Capillaria pudendotecta recorded from the ceca of wild and captive swans, except for the lack of vaginal appendages in female worms and shorter esophagi relative to the body length in both male and female worms. Phylogenetically, these two species were closely related, although substantial nucleotide changes were noted. The 18S rDNA nucleotide sequences of the species isolated here were consistent with the recent taxonomic system established for Capillariidae based primarily on the morphology of male caudal ends.
