| helminth parasites of beef cattle in the east kimberley and victoria river districts of northern australia. | an investigation into the helminth species present in cattle in the east kimberley and victoria river districts of northern australia was conducted over a 2-year period based on bi-monthly total and differential worm counts in weaner cattle as well as on a post mortem survey of adult cattle sent for slaughter. the most important species found in young cattle were haemonchus placei and cooperia spp. only small numbers of bunostomum phlebotomum, nematodirus spathiger, oesophagostomum radiatum and ... | 1978 | 664015 |
| epidemiology of paramphistomosis in cattle. | the epidemiology of paramphistomosis in cattle was studied using tracer calves in a subtropical location in eastern australia. two species of paramphistomes were present; calicophoron calicophorum and paramphistomum ichikawai. the former species was the most abundant. gyraulus scottianus and helicorbis australiensis acted as intermediate hosts, respectively. paramphistome burdens varied seasonally and were dependent upon the number of infected host snails. peak fluke burdens and clinical paramph ... | 1991 | 1774118 |
| chemotherapy of paramphistomosis in cattle. | controlled tests were used to assess the efficacy of anthelmintics against immature paramphistomes, predominantly calicophoron calicophorum, in 127 calves which were exposed to contaminated pasture for 7 weeks, treated and slaughtered. when a combination product of oxyclozanide and levamisole was used, oxyclozanide at 18.7 mg/kg reduced parasite numbers in the small intestine, abomasum and rumen-reticulum by 61 to 96.1%, 50.0 to 92.6% and 56.5 to 98.1%, respectively. when 2 doses were given 3 da ... | 1987 | 3447575 |
| [superficial argentophilic structures in the miracidium and cercaria of paramphistomum microbothrioides price and mac intosh, 1944 (trematoda, paramphistomidae)]. | superficial argentophilic structures of the miracidium are identical to those observed in the other species of the genus. on the other hand, on the terebratorium, they are different from those of the miracidium of calicophoron calicophorum. cercarial papillae are rarely symmetrical and their number varies according to specimens. however differences between the species are obvious. if paramphistomum microbothrioides, p. microbothrium and p. daubneyi are related by acetabular papillae, the number ... | 1986 | 3566081 |

| [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 |
| phylogenetic relationships of the family campulidae (trematoda) based on 18s rrna sequences. | traditionally, the family campulidae has been associated either with the family fasciolidae, parasites of ruminants, or the acanthocolpidae, parasites of fishes, based on morphological similarities. since morphology does not seem to resolve clearly the problem of the relationships of campulids, we have used the sequences of the 18s rrna gene of the campulids zalophotrema hepaticum, campula oblonga and nasitrema globicephalae, the fasciolid fasciola hepatica, the acanthocolpid stephanostomum bacc ... | 1998 | 9820860 |
| discrimination of three amphistome species by pcr-rflp based on rdna its2 markers. | three bovine amphistomes, calicophoron calicophorum, orthocoelium streptocoelium and homalogaster paloniae, are common in japan. this study was carried out to describe its2 sequences in the 3 species, and to evaluate a pcr-rflp technique based on its2 sequence for the species identification in single eggs of the parasites. the its2 sequences of the three species contained 19 variable sites including one gap. the sequence difference between species was 4.2-5.3%. the three species of amphistomes w ... | 2003 | 12951429 |
| characterization of the second internal transcribed spacer of ribosomal dna of calicophoron daubneyi from various hosts and locations in southern italy. | isolates of the rumen fluke calicophoron daubneyi (digenea: paramphistomidae) from various hosts and three locations in southern italy were characterized genetically. the second internal transcribed spacer (its-2) of ribosomal dna (rdna) plus flanking 5.8s and 28s sequence (its-2+) was amplified from individual rumen flukes by pcr. pcr-linked restriction fragment length polymorphism (pcr-rflp) analysis was performed using four different restriction endonucleases, and pcr products were sequenced. ... | 2005 | 15961232 |
| paramphistomicidal efficacy of an experimental compound in sheep. | the aim of the present study was to determine the paramphistomicidal efficacy of methyl [5-chloro-6-(1-naphthyloxy)-1h-benzimidazol-2-yl]carbamate (alpha-carbamate) in experimentally infected sheep. sixteen crossbred rams were infected each with 600 metacercariae of calicophoron calicophorum. forty five days after infection, they were divided into four groups of four animals each. groups 1 to 3 received compound alpha-carbamate at a dose of 12, 18, and 24 mg/kg b/w, respectively; group 4 serving ... | 2008 | 18185943 |
| secondary structure analysis of its2 in the rdna of three indian paramphistomid species found in local livestock. | of paramphistomid trematodes, three species viz., homalogaster paloniae, calicophoron calicophorum and orthocoelium streptocoelium are commonly prevalent in bovine hosts in northeast india. the aim of the present study was to genetically characterise these species using rdna second internal transcribed spacer (its2) so as to supplement the morphological criteria substantiated by molecular findings. the annotated its2 region from h. paloniae, c. calicophorum and o. streptocoelium were found to be ... | 2010 | 21069539 |
| prevalence and sequence-based identity of rumen fluke in cattle and deer in new caledonia. | an abattoir survey was performed in the french melanesian archipelago of new caledonia to determine the prevalence of paramphistomes in cattle and deer and to generate material for molecular typing at species and subspecies level. prevalence in adult cattle was high at animal level (70% of 387 adult cattle) and batch level (81%). prevalence was lower in calves at both levels (33% of 484 calves, 51% at batch level). animals from 2 of 7 deer farms were positive for rumen fluke, with animal-level p ... | 2016 | 27043709 |
| molecular characterization of veterinary important trematode and cestode species in the mithun bos frontalis from north-east india. | helminth infections in the mithun bos frontalis, including the liver fluke fasciola gigantica, hepato-gastric amphistomes explanatum explanatum, paramphistomum epiclitum and calicophoron calicophorum, and the cestodes echinococcus granulosus and e. ortleppi were studied in north-east india over a 2-year period from 2012 to 2014. cystic echinococcosis caused by e. granulosus and e. ortleppi was found to be highly prevalent in the mithun, with e. ortleppi being reported for the first time. molecul ... | 2016 | 26343353 |
| development and validation of a mtdna multiplex pcr for identification and discrimination of calicophoron daubneyi and fasciola hepatica in the galba truncatula snail. | paramphistomosis and fasciolosis caused by calicophoron daubneyi and fasciola hepatica, respectively, are frequent and important trematodoses in ruminant livestock worldwide. both parasites use the same snail, galba truncatula, as intermediate host. the aim of this study was to develop and validate an analytical method based on a mitochondrial dna (mtdna) multiplex pcr technique which would allow the early and specific identification, in one step, of c. daubneyi and f. hepatica infection in g. t ... | 2013 | 23333073 |
