| identity of rumen fluke in deer. | as evidence is growing that in many temperate areas paramphistome infections are becoming more common and widespread, this study was undertaken to determine the role of deer as reservoirs for rumen fluke infections in livestock. a total of 144 deer faecal samples (88 from fallow deer, 32 from red deer and 24 samples from sika, sika/red deer hybrids) were screened for the presence of fluke eggs. based on the its-2 rdna locus plus flanking 5.8s and 28s sequences (its-2+), fluke eggs were identifie ... | 2014 | 25127736 |
| presence and species identity of rumen flukes in cattle and sheep in the netherlands. | the purpose of the study was to gain knowledge about the prevalence and identity of rumen flukes (rf) in cattle and sheep in the netherlands. routine faecal examinations of diagnostic submissions between may 2009 and september 2014 showed a mean annual herd or flock rf prevalence of 15.8% for cattle and 8.0% for sheep. prevalence in cattle was higher after 2012 than before, which may reflect a change in detection method as well as an increase in true prevalence. during november and december 2014 ... | 2017 | 28807308 |
| morphological and molecular characterization of explanatum explanatum from cattle and buffaloes in myanmar. | a robust molecular marker is needed for discrimination of amphistome species, because identification based on morphology alone requires specialized knowledge and techniques. in this study, we performed morphological and molecular characterization of explanatum explanatum, a species that causes severe liver damage in definitive host species. fifty-five adult amphistomes were collected from cattle and water buffaloes in myanmar. eighteen of the amphistomes, arbitrarily chosen, were morphologically ... | 2013 | 23117826 |
| rumen fluke in irish sheep: prevalence, risk factors and molecular identification of two paramphistome species. | rumen flukes are trematode parasites found globally; in tropical and sub-tropical climates, infection can result in paramphistomosis, which can have a deleterious impact on livestock. in europe, rumen fluke is not regarded as a clinically significant parasite, recently however, the prevalence of rumen fluke has sharply increased and several outbreaks of clinical paramphistomosis have been reported. gaining a better understanding of rumen fluke transmission and identification of risk factors is c ... | 2016 | 27430977 |
| molecular characterization of the its-2 fragment of paramphistomum leydeni (trematoda: paramphistomidae). | paramphistomosis has shown an increased spread over the last years in argentina, being in some regions an emerging parasitosis, which has motivated their study and identification. even when morphological features were reported, molecular characterization appears as a complementary and reliable tool. samples of paramphistomum leydeni collected since 2002 from different origin, definitive hosts, natural or experimental infections and preservation method were subjected to pcr-rflp for its2+ fragmen ... | 2010 | 21145661 |
| [presence in france of paramphistomum leydeni näsmark, 1937 (trematoda:paramphistomata) (author's transl)]. | the authors point out, for the first time, the presence of paramphistomum leydeni näsmark, 1937 in the rumen of cattle originating from loire-atlantique and camargue. the parasite is briefly described again and its systematic position is discussed. | 1980 | 7224534 |
| [superficial argentophilic structures of miracidia and cercaria of paramphistomum leydeni nasmark 1937]. | the life cycle of paramphistomum leydeni näsmark, 1937, is carried out in the laboratory. adults were obtained from the rumen of a naturally infected bos taurus in czechoslovakia. laboratory-reared planorbis planorbis experimentally infected shed the first cercariae two months after exposure to miracidia. argentophilic structures in miracidia and cercariae are described. in miracidia, these structures are similar to those previously described from species of paramphistomum: p. togolense, p. phil ... | 1984 | 6721375 |
| mitochondrial and nuclear ribosomal dna dataset supports that paramphistomum leydeni (trematoda: digenea) is a distinct rumen fluke species. | rumen flukes parasitize the rumen and reticulum of ruminants, causing paramphistomiasis. over the years, there has been considerable debate as to whether paramphistomum leydeni and paramphistomum cervi are the same or distant species. | 2015 | 25890015 |
| efficacy of oxyclozanide against adult paramphistomum leydeni in naturally infected sheep. | the aim of the current study was to assess oxyclozanide (ocz) efficacy against paramphistomum leydeni in naturally infected adult sheep. ocz concentrations in blood stream and gastrointestinal fluids collected from treated animals were also measured. fifteen p. leydeni naturally infected sheep were randomly divided into two groups: untreated control (n=5) and treated (n=10). the treated group was orally drenched with ocz (20mg/kg, day 0). a second dose was administered 72 h later. faecal samples ... | 2014 | 25458118 |
| molecular identification of the rumen flukes paramphistomum leydeni and paramphistomum cervi in a concurrent infection of the red deer cervus elaphus. | paramphistomosis, caused by paramphistomid flukes, is a gastrointestinal parasitic disease of domestic and wild ruminants. originally thought to be limited to the tropics and subtropics, the disease has recently been reported in temperate regions. here we describe the concurrent infection of a red deer doe (cervus elaphus) with paramphistomum leydeni and paramphistomum cervi. this is the first report of p. leydeni in croatia. flukes were identified on the basis of morphological keys (tegumental ... | 2016 | 27813468 |
