A patient who had a migratory cutaneous nodule and tumor removed for the second time was diagnosed as having the liver fluke, Fasciola hepatica. In this article, we present a case report of this peculiar manifestation of fascioliasis, as well as a general overview of the disease.

Rumen fluke is a parasitosis that infects ruminant animals across wide geographical range of countries. It severe infection in temperate and tropical climate regions Asia, Australia, Africa, Europe, which cause significant economic losses. In this review, the available information to date on rumen species infecting cattle buffaloes Asian countries evaluated. The citation search was performed th...

Epidemiological parameters such as transmission rate, rate of parasite-induced host mortality, and rate of development of host defenses can be assessed indirectly by characterizing the manner in which parasite burdens change with host age. For parasites that are host generalists, estimates of these important parameters may be host-species dependent. In a cross-sectional study, we determined age...

The electric power calculator (EPC) software, for the simulation and analysis of electrical networks at industrial frequency, is described in this article, including its source code operational diagram. Compared to well-known commercial EPC directly provides values voltages, currents, powers each subsystem. voltages currents are calculated, phasor notation, applying Kirchhoff’s laws, while obta...

The National Metrology Institute of Colombia (INM) uses high accuracy calibrators (such as Fluke 5720A/5730A) AC current reference standards. We describe the implementation at INM AC-DC transfer standards by single junction thermal converters (SJTC) to improve measurements and give traceability International System Units (SI) within country. measurement model, present uncertainty budget estimat...

Food-borne fluke infections/trematodiases are emerging as a major public health problem worldwide with over 40 million people affected and over 10% of world population at risk of infection. The major concentration of these infections is in Southeast Asian and Western Pacific Regions, where the epidemiological factors (including the prevalent socio-cultural food habits) are conducive for transmi...

BACKGROUND The human liver fluke, Opisthorchis viverrini, is designated as a group 1 carcinogen, and is the major risk factor for cholangiocarcinoma in endemic countries throughout Southeast Asia. Proteins in the excretory-secretory products and tegumental surface membranes of the fluke have been proposed to play pivotal roles in parasite survival in the host, and subsequent pathogenesis. These...

Passive intraperitoneal transfer of sera from Fasciola hepatica-infected sheep, cattle or rats can protect naive rats from F. hepatica infection, suggesting a parasite killing mechanism within the peritoneal cavity that is dependent on the presence of parasite-specific antibody. We investigated antibody-dependent cell-mediated cytotoxicity by resident peritoneal lavage cell populations, contain...
