| 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 |
| amplification of ribosomal dna of anoplocephalidae: anoplocephala perfoliata diagnosis by pcr as a possible alternative to coprological methods. | the diagnosis of tapeworm infections in horses relies on copro-diagnostic methods, which are time-consuming and of limited sensitivity for determination of the exact prevalence. the development of serological tests has slightly improved the detection of tapeworm infections, but more sensitive methods are still required. a polymerase chain reaction (pcr)-based approach may constitute a valuable tool to improve tapeworm diagnosis. nuclear ribosomal dna (rdna) is a useful target for species and/or ... | 2004 | 15381301 |
| anoplocephala perfoliata coproantigen detection: a preliminary study. | anoplocephala perfoliata has a prevalence as high as 60% in some geographical areas and has been associated with increased risk for serious conditions in the horse including bowel irritation, ileal impaction, and spasmodic colic. identification of infected animals based upon detection of eggs in feces is labor intensive and unreliable. this study involved the development of a test for a.perfoliata coproantigen using an antigen capture enzyme linked immunosorbent assay (elisa) and correctly disti ... | 2004 | 15631904 |
| factors associated with development of ileal impaction in horses with surgical colic: 78 cases (1986-2000). | deal impaction is prevalent in the south-eastern usa, where feeding of coastal bermuda hay has been implicated as a risk factor. alternatively, infection with the tapeworm anoplocephala perfoliata has been identified as a risk factor for ileal impaction in the uk. we hypothesised that feeding coastal bermuda hay and failure to administer routinely an anthelmintic with efficacy against tapeworms would place horses at risk of developing ileal impaction in the usa. seventy-eight horses, with surgic ... | 2002 | 12358048 |
| [endoparasitic fauna and incidence of species in yearling and adult horses in upper bavarian breeding farms with regular anthelmintic prophylaxis lasting for many years]. | in this epidemiological study 127 horses from five breeding farms in upper bavaria were included. the horses were coproscopically examined in intervals of four weeks over a 16-month period. since 1992 in all farms regular prophylactic treatments with anthelmintics have been carried out. in 127 horses at least five species were established, such as parascaris equorum, anoplocephala perfoliata, gasterophilus intestinalis and small strongyles, whose third stage larvae were characterized by eight or ... | 1997 | 9441048 |
| tapeworm infection is a significant risk factor for spasmodic colic and ileal impaction colic in the horse. | the association between the equine intestinal tapeworm anoplocephala perfoliata and specific types of intestinal disease was investigated by matched case-control study using coprological and serological diagnosis. we have previously shown that the host igg(t) response to 12/13 kda antigens of a. perfoliata correlates well with infection intensity, therefore this antibody response was used to investigate the risk of colic at different levels of parasite infection intensity. one hundred and three ... | 1998 | 9622319 |
| seasonal transmission of gastrointestinal parasites of equids in southern louisiana. | parasite-naive pony foals were used as sentinels to monitor transmission of gastrointestinal parasites of equids in louisiana during 4 seasons of the year. two annual periods were studied, 1988-1989 and 1992-1993. two or 3 foals each season were turned out to graze a contaminated pasture along with resident parasitized mares and their foals. after a grazing period of 8 wk, sentinel ponies were held in a parasite-free box stall for a period of 6 wk to allow parasites to develop, thus enhancing th ... | 2001 | 11780824 |
| reliability of coprological diagnosis of anoplocephala perfoliata infection. | three coprological methods were tested to establish the reliability of in vivo diagnosis of anoplocephala perfoliata. a total of 107 faecal samples were analyzed, and the presence of tapeworms were confirmed postmortem in 24 animals with burdens that ranged from 1 to 248 worms; most of them (71%) with less than 100 parasites. best results were obtained with a combination of two sedimentation/flotation methods, detecting only half the parasitized animals (54% sensitivity). no relationship could b ... | 1998 | 9493312 |
