Red deer (Cervus elaphus) are hosts of liver fluke (Fasciola hepatica); yet, prevalence is rarely quantified in wild populations. Testing fresh samples from remote regions by faecal examination (FE) can be logistically challenging; hence, we appraise frozen storage and the use of a coproantigen ELISA (cELISA) for F. hepatica surveillance. We also present cELISA surveillance data for red deer fr...

Bovine tuberculosis (BTB) is a significant and intractable disease of cattle caused by Mycobacterium bovis. In the United Kingdom, despite an aggressive eradication programme, the prevalence of BTB is increasing with an unexplained, exponential rise in cases year on year. Here we show in a study involving 3,026 dairy herds in Engla...

background: the aim of this study was to compare superoxide dismutase (sod) activity in fasciola hepatica and fasciola gigantica parasites. materials: f. gigantica and f. hepatica helminths were collected from abattoir and cultured in buffer media for 4 h at 37 °c. excretory-secretory (es) products were collected, centrifuged and stored at - 20 ◦ c. e-s protein concentration was measured by bra...

the aim of this study was to detect the genotype of fasciola spp. in meshkin-shahr, ardabil province, northwestern iran in different hosts using pcr-rflp.the parasite hosts included cattle, and sheep. overall, 70 adult flukes from livers of slaughtered animals were collected from the abattoirs of aforementioned area. the included 35 samples from infected sheep and 35 samples from 35 infected ca...

Fasciolosis is a widely distributed disease in livestock in South America but knowledge about the epidemiology and the intermediate hosts is relatively scarce in Ecuador. For three months, lymnaeid snails were sampled (n = 1482) in Pichincha Province at two sites located in a highly endemic area. Snails were identified (based on morphology and ITS-2 sequences) and the infection status was estab...

Fasciola hepatica is a parasitic trematode that causes serious losses to livestock producers, and also zoonotic disease. The limitations of chemotherapy for the control of fasciolosis have led to significant interest in the development of vaccines to protect cattle and sheep from infection. However, relatively few studies have concentrated on the mechanisms of invasion of the gut by newly excys...

OBJECTIVES The trematocidal properties of a synthetic peroxide, 1,2,4-trioxolane (OZ78) were determined both in vivo and in vitro. METHODS Two weeks post-infection Echinostoma caproni-infected mice were administered single oral doses of 400-1000 mg/kg OZ78. Fasciola hepatica-infected rats were treated orally with 50-400 mg/kg OZ78 3 and 8-9 weeks post-infection. Worm burden reductions were as...

Este estudio se llevó a cabo para establecer la prevalencia e identificar los factores de riesgo asociados con las infestaciones por tremátodos en ganado lechero Holstein el valle Paipa-Boyacá. Las muestras fecales recogidas 100 bovinos seleccionados aleatoriamente examinaron utilizando una técnica sedimentación simple recuento diferencial huevos tremátodos. Se buscaron tres grupos tremátodos, ...

A cross-sectional study was conducted to estimate the prevalence of Fasciola hepatica (F. hepatica) infection in water buffalo (Bubalus bubalis) in Alexandria, Beheira, and Kafr el-Sheikh governorates (provinces) of the Nile Delta in Egypt and to identify the underlying risk factors associated with the infection. A total of 29 farms (10 in Alexandria, 10 in Beheira, and 9 in Kafr el-Sheikh) wer...

The pond snail Lymnaea stagnalis is an intermediate vector for the liver fluke Fasciola hepatica, a common parasite of ruminants and humans. Yet, despite being a disease of medical and economic importance, as well as a potentially useful comparative tool, the genetics of the relationship between Lymnaea and Fasciola has barely been investigated. As a complement to forthcomingF. hepatica express...
