Serologic test for diagnosis of Fasciola hepatica by Carla Jean Farrell Download PDF EPUB FB2

Various types of immunodiagnostic tests for Fasciola have been developed. CDC provides serologic testing using an immunoblot assay that detects IgG antibody to FhSAP2, a recombinant antigen derived from Fasciola hepatica.

As always, test results should be interpreted in context, with expert consultation. In general, serologic testing can be useful. Serum antibody ELISA tests for the diagnosis of F.

hepatica have been around for decades and have various reported sensitivities and specificities ranging from % to % and % to % respectively. The ELISA used in this study is not commercially available and was first presented by Salimi-Bejestani et al.

in with a sensitivity of Cited by:   The diagnosis of fasciolosis is usually based on the detection of F. hepatica eggs in faeces or F. hepatica -specific antibodies in serum. Recently, a method based on detection of a F. hepatica -specific copro-antigen has been developed and commercialized (Mezo et al., ).Cited by: With a provisional diagnosis of Fasciola infection, three stool specimens were collected, and Fasciola serology was obtained.

Although stool analysis did not identify any Fasciola eggs, our patient was treated empirically with two doses of mg of triclabendazole, 12 h : Ian Lockart, Amitabha Das, Neil D Merrett, Miriam T Levy.

Test Frequency and Turnaround Time (TAT) Fasciola serology is a Referred Out Test. Samples are sent to the National Reference Centre for Parasitology (NRCP) in Montreal, Quebec. Turnaround time is up to 42 days from receipt by PHO Laboratory. The English summary appended to the paper is as follows: "To evaluate the applicability of serological tests in the intravital diagnosis of Fasciola hepatica invasion, sera collected in a slaughter-house from beef cattle were tested by complement fixation, passive haemagglutination, and ring precipitation : B.

Titres in sera from field-infected sheep were related to fluke burdens. Indirect haemagglutination, counter-immunoelectrophoresis and double immunodiffusion were compared.

A specific IHAT using purified adult Fasciola hepatica f1Ag (Laboratoires Fumuze Diagnostic) was used for serologic diagnosis. The result was positive at 1/ (normal Drug therapy with triclabendazole was administered to the patient. If protozoal, filarial, or trypanosomal infection is strongly suspected, test should be performed at least three times with samples obtained at different times in the fever cycle.

Methodology Wright stain; microscopic examination of thick and thin peripheral blood smears stained with Romanovsky dye (in particular Giemsa).

Causal Agent. The trematodes Fasciola hepatica (also known as the common liver fluke or the sheep liver fluke) and Fasciola gigantica are large liver flukes (F. hepatica: up to 30 mm by 15 mm; F.

gigantica: up to 75 mm by 15 mm), which are primarily found in domestic and wild ruminants (their main definitive hosts) but also are causal agents of fascioliasis in humans. The IDEXX Fasciolosis Verification Test is made reliable by using the f2 antigen purified from Fasciola extracts.

The f2 antigen is very immunogenic and highly specific for Fasciola hepatica. It has been standardized according to the hemagglutination method (HA) developed by the team of Dr. Levieux (INRA). Blood and fecal samples were collected for coproscopy and serology for F.

hepatica. Data were subjected to Chi-square analysis, analysis of variance, and receiver operating characteristics curve. For the purposes of diagnostic testing for F.

hepatica, DRG F. hepatica IgG ELISA (EIA, DRG Instruments, Germany) kits were employed as the test that secures diagnosis in F. hepatica. DNA multigene characterization of Fasciola hepatica and Lymnaea neotropica and its fascioliasis transmission capacity in Uruguay, with historical correlation, human report review and infection risk analysis.

PLOS Neglected Tropical Diseases, Vol. 11, Issue. 2, p. eCited by:   A serological and coprological survey of fasciolosis was conducted in bovine hosts from the Sargodha district, Pakistan using excretory–secretory (ES) antigens of Fasciola gigantica from cattle and buffaloes.

Livers, faecal and blood samples of cattle and buffaloes were collected from slaughterhouses and examined for the presence of any Fasciola in bile ducts and ova in by: 3. Diagnostic Tests: The definitive and most widely used form of diagnosis is the directly observed presence of Fasciola hepatica eggs either in a stool sample, duodenal aspirate or biliary aspirate.

However, the flukes do not begin to produce eggs until roughly 4 months after infection. Purpose of review: This review aims at describing the latest research in Fasciola epidemiology, diagnosis, treatment, and control in endemic countries. Recent findings: The geographic distribution and range of reservoirs for Fasciola hepatica continues to expand.

The impact of fascioliasis goes beyond human disease to affect food security and income in developed and developing by: 9. the use of elisa to detect antigen release from juvenile fasciola hepatica. comparing the use of an enzyme linked immunosorbent assay and an agar gei immunodiffusion test.

serological diagnosis of pseudorabies using enzymelinked immunosorbent assay elisa. Fasciola hepatica, also known as the common liver fluke or sheep liver fluke, is a parasitic trematode (fluke or flatworm, a type of helminth) of the class Trematoda, phylum infects the livers of various mammals, including disease caused by the fluke is called fasciolosis or fascioliasis, which is a type of helminthiasis and has been classified as a neglected.

No samples were positive for Fasciola hepatica in the first phase of the coprological survey. Only Ascaris lumbricoides were observed, in the second phase, fecal samples were analyzed from 8 serology-reactive individuals, and in 1/8 (%) a Fasciola hepatica egg was found measuring μm in length and 75 μm in width (Figure 3).

Objectives To improve the diagnosis of human fascioliasis caused by Fasciola hepatica and Fasciola gigantica, we evaluated the diagnostic accuracy of an enzyme‐linked immunosorbent assay (ELISA), with Fasciola antigen from the adult liver fluke, for the detection of IgG against fascioliasis in human sera.

Methods The sera of 54 fascioliasis cases, originating from three endemic Cited by: SUMMARY:In recent years multidisciplinary studies have furnished additional knowledge on different aspects of human fascioliasis caused by Fasciola hepatica. Today, the overall conception we have about this parasitic disease is pronouncedly different from only a few years before.
