| oxibendazole: critical anthelmintic trials in equids. | the efficacy of oxibendazole against gastrointestinal parasites of horses was evaluated by the critical test method. naturally infected ponies of various ages were given single oral doses of 5, 10, or 15 mg-kg of bodyweight. the drug was highly effective against adult large strongylids (strongylus vulgaris, s edentatus, s equins), adult small strongylids (especially species of the genera cylicostephanus, cylicocyclus, cyaathostomum, and triodontophorus), and adult and larval stages of the large ... | 1975 | 1216434 |
| production and characterization of monoclonal antibodies against excretory-secretory products of fasciola hepatica. | four monoclonal antibodies (mabs) (9.49, 24.27, 46.71 and 179.57) were produced against fasciola hepatica excretory-secretory products. isotype analysis revealed the antibodies to be igm, igg3, igg1, and igm. in immunoblot assays, the mabs recognized different antigenic polypeptides migrating between 29 and 180 kda. specificity of the mabs was evaluated by elisa against antigens of fascioloides magna, anoplocephala magna, stichorchis subtriquetrus, haemonchus contortus, sheep liver extract (sle) ... | 1991 | 1788930 |

| gastrointestinal helminths of ponies in louisiana: a comparison of species currently prevalent with those present 20 years ago. | a survey in louisiana of gastrointestinal helminths recovered at necropsy from 117 ponies with minimal exposure to anthelmintics between 1989 and 2000 is compared with a survey conducted 20 yr earlier in the same region. an objective of this study was to determine whether species diversity has been affected by the advent and use of the macrocyclic lactone (ml) parasiticides and by the increased anthelmintic pressure on the helminth species infecting the general equine population. twenty-six cyat ... | 2002 | 12537106 |
| epidemiological studies on equine cestodes in central spain: infection pattern and population dynamics. | an epidemiological study on equine cestodosis was carried out in central spain. a total of 372 digestive tracts from equids slaughtered in abattoirs located in central spain were studied from november 2001 to may 2004. anoplocephala perfoliata was detected in 24% of the animals and anoplocephala magna in 18%. individual tapeworm burden was from 1 to 491 tapeworms for a. perfoliata and from 1 to 64 tapeworms for a. magna. low tapeworm burdens (less than 30 cestodes) predominated significantly (p< ... | 2005 | 15908124 |
| characterization of the complete mitochondrial genome of the cloacal tapeworm cloacotaenia megalops (cestoda: hymenolepididae). | the cloacal tapeworm cloacotaenia megalops (hymenolepididae) is one of the most common cestode parasites of domestic and wild ducks worldwide. however, limited information is available regarding its epidemiology, biology, genetics and systematics. this study provides characterisation of the complete mitochondrial (mt) genome of c. megalops. | 2016 | 27595753 |
| complete mitochondrial genome of anoplocephala magna solidifying the species. | the 2 species of the genus anoplocephala (anoplocephalidae), a. perfoliata and a. magna, are among the most important equine cestode parasites. however, there is little information about their differences at the molecular level. the present study revealed that the mitochondrial (mt) genome of a. magna was 13,759 bp in size and 700 bp shorter than that of a. perfoliata. the 2 species includes 2 rrna, 22 trna, and 12 protein-coding genes each. the size of each of the 36 genes was the same as that ... | 2016 | 27417096 |
| endoparasites of horses from the formiga city, located in center-west region of the state of minas gerais, brazil. | with the aim of studying the endoparasite fauna of horses from the formiga city, located in center-west region of the state of minas gerais, 25 animals that were naturally infected with helminths were evaluated. by means of parasitological necropsies, different endoparasites were found. the subfamily cyathostominae presented the highest incidence, followed by trichostrongylus axei, oxyuris equi, triodontophorus serratus, strongyloides westeri, strongylus edentatus, habronema muscae, parascaris e ... | 2017 | 25517536 |
| new multiplex pcr method for the simultaneous diagnosis of the three known species of equine tapeworm. | although several techniques exist for the detection of equine tapeworms in serum and feces, the differential diagnosis of tapeworm infection is usually based on postmortem findings and the morphological identification of eggs in feces. in this study, a multiplex polymerase chain reaction (pcr)-based method for the simultaneuos detection of anoplocephala magna, anoplocephala perfoliata and anoplocephaloides mamillana has been developed and validated. the method simultaneously amplifies hypervaria ... | 2015 | 25498328 |
| coprologically diagnosing anoplocephala perfoliata in the presence of a. magna. | current copro-diagnostic tests for anoplocephala perfoliata show high variation in their sensitivity and given the morphological similarity of anoplocephala spp. eggs, this could be related to the presence of anoplocephala magna alone or co-existing with a. perfoliata. in the present study, coprology was significantly more sensitive (p<0.01) at detecting a. magna than a. perfoliata. this difference was independent of the parasite burden and was greater when testing was limited to horses with mat ... | 2014 | 24877786 |
| differential diagnosis of equine cestodosis based on e/s and somatic anoplocephala perfoliata and anoplocephala magna antigens. | the tapeworm responsible for equine colic, anoplocephala perfoliata, is considered the most common intestinal tapeworm of horses worldwide. however, there is evidence that anoplocephala magna has a similar prevalence in north america and spain, and possibly in other countries, highlighting the need for diagnostic methods capable of distinguishing between these two species. currently, immunodiagnosis of a. perfoliata is based on the identification of the 12/13 kda excretory/secretory (e/s) a. per ... | 2012 | 22763349 |
| cysticercoids of anoplocephala magna (eucestoda: anoplocephalidae) experimentally grown in oribatid mites (acari: oribatida). | anoplocephala magna eggs found in the rectal content of a naturally infected zebra from south africa were fed to scheloribates pallidulus under laboratory condition. mites remained in contact with the eggs for one week and were late kept for 30 days in an incubator at 28°c. at the end of the experiment, 19 out of 136 mites contained typical anoplocephalidae cysticercoids in their body cavity in numbers between one and three. the average size of the metacestodes varied depending on intensity of i ... | 2012 | 22721940 |
