True Infection by Capillaria hepatica in a Dog

Capillaria hepatica infestation.

Capillaria hepatica is a very rare zoonotic infestation which primarily infests rodents and is rarely found in humans. The presenting features are fever of unknown origin, hepatomegaly and peripheral eosinophilia. Liver biopsy remains the cornerstone of diagnosis. Treatment of choice is Albendazole and outcome is generally good.

Capillaria hepatica Pseudoinfection

A 54-year-old male Matsigenka native from the Manu jungle of Peru presented with the eggs shown in Figure 1. Kato Katz (Figure 2) testing revealed 1,500 eggs/g stool. The white blood cell count with differential, liver enzymes, and sputum examination were normal. No treatment was administered; however, repeated stool testing was negative. Pseudocapillariasis caused by Capillaria hepatica was di...

A contribution to the diagnosis of Capillaria hepatica infection by indirect immunofluorescence test.

A highly specific pattern of immunofluorescence was noted when sera from Capillaria hepatica-infected rats were tested against the homologous worms and eggs present either in paraffin or cryostat sections from mouse liver. The pattern was represented by a combined apple green fluorescence of the internal contents of worms and eggs, which persisted in serum-dilutions of 1:400 up to 1:1600. Unequ...

Serological detection of Capillaria hepatica by indirect immunofluorescence assay.

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 a...
