Calodium hepaticum já foi relatado parasitando o parênquima hepático de diversas espécies de mamíferos, porém é infrequente em cães. O presente artigo tem o objetivo de descrever dois casos de capilariose hepática em cães, diagnosticados em um período de um mês na região de Santa Maria, Rio Grande do Sul, Brasil. O primeiro cão apresentava sintomatologia clínica de insuficiência cardíaca, e ovos de Calodium hepaticum foram encontrados ocasionalmente no exame histopatológico do fígado. O segundo animal apresentava mucosas ictéricas e ascite. No hemograma, ficou evidente a presença de anemia arregenerativa e, na avaliação de bioquímica sérica, percebeu-se aumento de fosfatase alcalina, alanina aminotransferase e hipoalbuminemia. A análise do liquido cavitário foi compatível com transudato modificado. No exame histopatológico, foram observados numerosos ovos bioperculados de Calodium hepaticum, dispostos aleatoriamente pelo parênquima hepático, com reação granulomatosa e fibrosa adjacente aos ovos. A existência de maior número de cães infectados demonstra a necessidade de controle da população de roedores.

Hepatic capillariasis is a rare and neglected zoonosis affecting wild and synanthropic small rodents. It is caused by infection with Calodium hepaticum in liver. Despite the worldwide distribution of the host Rattus norvegicus (brown or street rats) in the urban area, the epidemiological status of this parasitosis remains unknown. In the present study, we examined a total of 27 brown rats from the city centre and a garden (four km from the city centre) of Marseille, France. All rats were autopsied and 52% showed the presence of C. hepaticum eggs in the liver. This result draws general attention to public health risks, since street rats are living near the human population.

Humans can get infected with several zoonotic diseases from being in close contact with rats. This study was aimed at determining the prevalence and histopathological changes caused by Calodium hepaticum and Cysticercus fasciolaris in infected livers of wild caught urban rats. Of the 98 urban rats (Rattus rattus diardii and Rattus norvegicus) autopsied, 64.3% were infected; 44.9% were infected with Caladium hepatica, 39.3% were infected with Cysticercus fasciolaris, and 20.4% were infected with both parasites. High infection rates suggest that urban rats are common reservoir for both parasites, which are potentially a threat to man. Calodium hepaticum infections were identified by the presence of ova or adults in the liver parenchyma. They appear as yellowish white nodules, measuring 1–7 mm in diameter or in streaks scattered widely over the serosal surface of the liver. Cysticercus fasciolaris infections are recognized morphologically by their shape (round or oval) and are creamy white in colour. Histological studies of Calodium hepaticum showed areas of granulomatous lesions with necrotic areas around the dead ova and adults. In almost all cases, the rats appeared robust, looked healthy, and showed no visible signs of hepatic failure despite the fact that more than 64.0% of their livers were infected by either one or both parasites.

Introduction: Hepatic capillariosis, caused by Capillaria hepatica (Calodium hepaticum) (Bancroft, 1893), Travassos, 1915 (Nematoda, Trichinelloidea, Capillariidae), is a common zoonosis in rodents but is rare in humans. Seventy-two cases in humans have been reported worldwide since the first case was described by MACARTHUR in 192417,27. This study aimed to determine the prevalence of Capillaria hepatica in humans and rodents in an urban area of Porto Velho, the capital of Rondônia, in Brazil. Methods: After conducting a census of the area, 490 residents were randomly selected, and, after signing a term of consent, provided blood samples that were screened for anti-Capillaria hepatica antibodies. Simultaneously, rats were captured to assess the prevalence of this parasite in rodents by histopathological examination in liver sections. Results: A prevalence of 1.8% was found among residents who had specific antibodies at a dilution of 1:150, indicating exposure to parasite eggs; 0.8% of the subjects also had positive titers at a dilution of 1:400, indicating true infection. The prevalence in rats was 2%. Conclusions: The prevalence of infection with this parasite among humans and rats was low. While the prevalence encountered among humans was within the limits reported in the literature, the prevalence among rodents was much lower.
