Capillaria hepatica in china
World Journal of Gastroenterology, 2010Co-Authors: Chaoding Li, Huilin Yang, Ying WangAbstract:Capillaria hepatica (C. hepatica) is a parasitic nematode causing hepatic Capillariasis in numerous mammals. Ecologic studies showed that the first hosts of C. hepatica were rodents, among which rats had relatively high infection rates, which explains why C. hepatica spreads globally. Anatomical studies showed that the liver was the principal site of colonization by these parasites and physical damage tended to occur. Although C. hepatica might lead to serious liver disorders, relevant clinical reports were rare, because of the non-specific nature of clinical symptoms, leading to misdiagnosis. This review mainly focuses on the biological characteristics and epidemiology of C. hepatica in China and histopathologic changes in the liver, with expectation of gaining a better understanding of the disease and seeking more effective treatment.

Zur Helminthenfauna des Rotfuchses (Vulpes vulpes L.) in Südniedersachsen Teil 1: Nematoden und Trematoden
Zeitschrift für Jagdwissenschaft, 1994Co-Authors: Gudrun Steinbach, Alice Welzel, M. Keyserlingk, M. StoyeAbstract:De novembre 1991 à mars 1992, 400 renards ont été étudiés quant à la présence de Nématodes et de Trématodes. Les renards provenaient des districts de Göttingen, Osterode, Northeim, Holzminden, Hildesheim, Hameln-Pyrmont et Schaumburg. Furent examinés l'intestin, la vésicule biliaire, la vessie et la musculature de tous les animaux ainsi que 72 poumons et trois embryons; 37,6% des renards étaient, dans un rapport des sexes de 52,4% de mâles pour 47,6% de femelles, âgés d'1 an et, dans 62,4% des cas, âgés de plus d'un an. Dans 98,3% des vessies on a trouvé Capillaria plica et dans 77,8% des poumons Capillaria aerophila; 56,5% des renards étaient contaminés par Toxocara canis , 13% avec Unicaria stenocephala , 5,5% avec Crenosoma vulpis et 4,5% avec Toxascaris leonina . La présence de larves de Trichinella spiralis ne put être vérifiée chez aucun renard. Par contre, des larves d'Ankylostomides et de Toxocara canis ont été trouvées dans la musculature. Dans un embryon, la présence d'une seconde larve de Toxocara canis a été vérifiée. Un œuf de Trématode a été trouvé dans le liquide de la vésicule biliaire. Des concentrations régionales de la plupart des espèces de cette helminthofaune n'ont pas été constatées. Seules des contaminations par Toxascaris leonina sont plus fréquentes dans le District d'Osterode que dans les autres régions étudiées. Lex taux élevés de présence de Capillaria plica et de C. aerophila ainsi que la contamination, indépendante de l'âge, par ces espèces indiquent la faible réaction immunologique vis-à-vis des espèces de Capillaria . Von November 1991 bis März 1992 wurden 400 Rotfüchse auf das Vorkommen von Nematoden und Trematoden untersucht. Die Füchse stammten aus den Landkreisen Göttingen, Osterode, Northeim, Holzminden, Hildesheim, Hameln-Pyrmont und Schaumburg. Untersucht wurden Darm, Gallenblase, Harnblase und Muskulatur von allen Tieren sowie 72 Lungen und drei Embryonen. 37,6% der Füchse waren, bei einem Geschlechterverhältnis von 52,4% männlichen zu 47,6% weiblichen Tieren, bis zu einem Jahr, 62,4% über ein Jahr alt. In 98,3% der Harnblasen wurde Capillaria plica und in 77,8% der Lungen Capillaria aerophila gefunden, 56,5% der Füchse waren mit Toxocara canis , 13% mit Uncinaria stenocephala , 5,5% mit Crenosoma vulpis und 4,5% mit Toxascaris leonina infiziert. Larven von Trichinella spiralis konnten bei keinem Fuchs nachgewiesen werden. In der Muskulatur wurden aber Larven von Ankylostomiden und Toxocara canis gefunden. In einem Embryo erfolgte der Nachweis einer zweiten Larve von Toxocara canis . Ein Trematodenei wurde in der Gallenblasenflüssigkeit festgestellt. Regionale Konzentrationen des Vorkommens waren bei den meisten Arten nicht zu erkennen. Lediglich Infektionen mit Toxascaris leonina kamen im Landkreis Osterode wesentlich häufiger als in den anderen untersuchten Regionen vor. Die hohen Nachweisraten von Capillaria plica und Capillaria aerophila sowie die Altersunabhängigkeit des Befalls mit diesen Arten wiesen auf geringe immunologische Abwehr gegen Capillaria-Arten hin. From November 1991 to March 1992 400 red foxes were examined for the presence of nematodes and trematodes. The foxes came from the districts of Göttingen, Osterode, Northeim, Holzminden, Hildesheim, Hameln-Pyrmont, and Schaumburg. The intestinal tract, gall bladder, urinary bladder, and the muscles of all animals were investigated as were 72 lungs and 3 embryos. 37.6% of the foxes were less than 1 year old, and 62.4% were older. 52.4% of all foxes were male, and 47.6% were female. Capillaria plica was found in 98.3% of the urinary bladders examined and Capillaria aerophila occurred in 77.8% of the lungs. 56.5% of the foxes were infected with Toxocara canis , 13% with Uncinaria stenocephala , 5.5% with Crenosoma vulpis , and 4.5% with Toxascaris leonina . Larvae of Trichinella spiralis could not be demonstrated in any of the foxes. In the muscles, however, larvae of ankylostomides and Toxocara canis were found. One embryo also had a larvae of Toxocara canis . Trematode infections were evident in the gall bladder fluid. Regional concentrations of the various parasite infestations were not apparent for most of the species investigated. Only Toxascaris leonina occurred much more frequently in the district of Osterode. The high rates of Capillaria plica and Capillaria aerophila infestations as well as the lack of a correlation of these infections with age demonstrate a low immunity against these parasites.

Investigation of Small Mammals on Capillaria hepatica in Weishan County
Endemic Diseases Bulletin, 1999Co-Authors: Xiong Meng-taoAbstract:Altogether 908 small mammals were captured from Weishan County, Yunnan Province in September,1998. They were identified as 13 species, belong to 7 genera, 5 families, 4 orders. The dominant species of 13 species was R.flavipectus, its constituent ration was 97.36%. 905 small mammals were examined, 438 small mammals of 4 species were infected by Capillaria hepatica, the prevalence was 48.40%. 435 samples of 881 R.flavipectus were infected, the prevalence was 49.38%.The results showed that the prevalence of small mammals was high, the human and stock may be infected by Capillaria hepatica in Weishan County. It is necessary for prevention and control of Capillaria hepatica.

Capillaria hepatica parasitism
Indian Journal of Pediatrics, 1996Co-Authors: Hema Govil, Meena DesaiAbstract:Capillaria hepatica is rarely encountered in humans, with fewer than 30 documented cases. The clinico-pathological features of Capillaria hepatica infection, diagnosed on liver biopsy of a 6-year-old child are discussed. Pathologically, it is characterised by prominent granulomatous lesions in the liver surrounding the eggs, which on cursory examination may be confused withSchistosoma mansoni.

serological detection of Capillaria hepatica by indirect immunofluorescence assay
Journal of Clinical Microbiology, 2000Co-Authors: Martina Junckervoss, Heinrich Prosl, Helga Lussy, Ulrike Enzenberg, Herbert Auer, Norbert NowotnyAbstract:In this paper, a serological assay for the detection of antibodies to Capillaria hepatica, a zoonotic parasite, is described. In the past, the only way of detecting Capillaria hepatica was to perform a liver biopsy. The indirect immunofluorescence (IIF) assay, based on liver sections of naturally infected mice and human serum samples, is suitable for detecting early stages of human infections and for screening purposes. No cross-reactivity with other parasitic infections was detected. We have applied the IIF assay to serum samples of 60 employees of the Zoological Garden of Vienna, Schonbrunn, Austria, and found one positive and one questionable sample.
