capillaria hepatica parasitism. | 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 with schistosoma mansoni. | 1996 | 10830044 |
hepatic pathology in capillaria hepatica infected mice. | septal fibrosis of the liver regularly develops in rats infected with capillaria hepatica. to find out whether such fibrosis also occurs in mice, 20 animals were submitted to infection with either 100 or 300 embryonated eggs and histologically examined after several periods of time, from 30 to 110 days afterwards. results showed that mice developed acute, severe, diffuse and focal hepatic lesions that were soon modulated to focal areas of fibrosis containing eggs and worm remnants, despite the f ... | 2000 | 10936946 |
capillaria hepatica, a parasite of zoonotic importance--a brief overview. | this review briefly elucidates the biology and mode of transmission of the parasite capillaria hepatica, an cuimial parasite. occasional transmitted to man. | 1999 | 10937307 |
hepatic capillariasis (capillaria hepatica) in porcupines (erethizon dorsatum) in pennsylvania. | tissues of 53 adult porcupines (erethizon dorsatum) from pennsylvania were obtained for histopathologic examination. hepatic capillariasis was recorded in 9% of the porcupines. an additional 11% of the liver sections showed lesions that were compatible with migration by capillaria hepatica. because only 1 section of the liver per animal was examined microscopically, the documented prevalence of c. hepatica in pennsylvania is considered conservatively low. however, this condition was subclinical, ... | 2000 | 11021437 |
hepatic capillariasis in rats: a new model for testing antifibrotic drugs. | rats infected with the helminth capillaria hepatica regularly develop septal hepatic fibrosis that may progress to cirrhosis in a relatively short time. because of such characteristics, this experimental model was selected for testing drugs exhibiting antifibrosis potential, such as pentoxifylline, gadolinium chloride and vitamin a. hepatic fibrosis was qualitatively and quantitatively evaluated in liver samples obtained by partial hepatectomy and at autopsy. the material was submitted to histol ... | 2000 | 11050664 |
capillaria hepatica: a spurious case with a brief review. | a 12-year-old bunun aboriginal school student in sanmin district kaohsiung county, southern taiwan, was found to have capillaria hepatica eggs in the feces during a survey on intestinal parasitic infection in 1997. moreover, this student was also infected with trichuris trichiura and ascaris lumbricoides. the c. hepatica eggs were light yellowish-brown in color, 54 (40-60) microns in length and 29 (25-35) microns in width with a 3 (3-4) microns thick shell and two colorless egg plugs 7 (5-9) x 6 ... | 2000 | 11079295 |
effect of interferon-alpha on experimental septal fibrosis of the liver - study with a new model. | interferon-alpha is used in antiviral therapy in humans, mainly for viral hepatitis b and c. an anti-fibrotic effect of interferon has been postulated even in the absence of anti-viral response, which suggests that interferon directly inhibits fibrogenesis. rats infected with the helminth capillaria hepatica regularly develop diffuse septal fibrosis of the liver, which terminates in cirrhosis 40 days after inoculation. the aim of this study was to test the anti-fibrotic effect of interferon in t ... | 2001 | 11313641 |
capillaria hepatica infection in wild brown rats (rattus norvegicus) from the urban area of milan, italy. | forty-seven wild brown rats (rattus norvegicus) collected from the urban area of milan (italy) were screened for capillaria hepatica liver infection. the liver of each rat was grossly and histologically examined for the presence of c. hepatica adults, eggs and typical c. hepatica induced lesions. in 17 rats (36%) liver lesions consistent with c. hepatica infection were detected. grossly, white-yellow nodules of 1-5 mm in diameter were present, either scattered on the liver surface or localized i ... | 2001 | 11393820 |
worm load and septal fibrosis of the liver in capillaria hepatica-infected rats. | inocula, varying from 15 to 1,000 embryonated capillaria hepatica eggs, were administered to young adult rats by gastric tube, in an attempt to investigate the influence of worm load in the production of septal fibrosis of the liver. low doses of 15, 30 or 50 eggs were sufficient to produce septal fibrosis, but it appeared with variable degrees of intensity and always with focal distribution. septal fibrosis became diffuse, progressive with time, and already well developed 40 days after infectio ... | 2001 | 11685269 |
pathogenesis of hepatic septal fibrosis associated with capillaria hepatica infection of rats. | septal fibrosis is a common form of hepatic fibrosis, but its etiology and pathogenesis are poorly understood. rats infected with the helminth capillaria hepatica constitute a good experimental model of such fibrosis. to investigate the pathogenetic contribution of the several parasitic factors involved, the following procedures were performed in rats: a) regarding the role of eggs, these were isolated and injected either into the peritoneal cavity or directly into the liver parenchyma; b) for w ... | 2001 | 11813054 |
arthropod and helminth parasites of the wild guinea pig, cavia aperea, from the andes and the cordillera in peru, south america. | as part of an ongoing research project concerning the diversity and distribution of parasites of caviidae in south america, 143 wild guinea pigs (cavia aperea) were collected from 3 localities in the andean highlands of peru. samples were collected between november 1996 and may 1999 and included representatives of arthropods, nematodes, and trematodes. seven species of arthropods: leptopsylla segnis (27.3%), tiamastus cavicola (6.9%), gliricola porcelli (55.2%), hoplopleura alata (6.9%), polypla ... | 2002 | 12054024 |
