  • Doramectin efficacy against the kidney worm, Stephanurus dentatus in sows
    Veterinary Parasitology, 1996
    Co-Authors: T B Stewart, S.e. Wiles
    Abstract:

    Abstract Sixteen sows passing Stephanurus dentatus eggs in their urine were bought on the local market and placed in individual pens with solid concrete floors in an open-sided barn. Water was supplied by nipple waterers and sows were fed individually 1.8 kg feed daily. First, urine samples were taken at dawn on days −8 and −7 and weights were taken on day 0. Sows were assigned to one of two groups on the basis of average urine egg counts and weights. Group T1 sows were each injected IM in the neck with sterile saline at the rate of 1.5 ml per 50 kg and group T2 sows were each injected IM with doramectin at the rate of 300 μg kg −1 on day 0. Urine samples were again taken on days 56 and 57 and the sows were necropsied on day 57. Urine of all doramectin treated sows were test negative worm eggs on days 56 and 57 as was one control sow, whereas the average count for controls was 3762 eggs ml −1 . No worms were found in doramectin treated sows and a total of 499 were found in the controls for an average of 62 per sow. The majority of worms were in the perirenal area and kidneys, a few were scattered in liver, lungs, abdominal muscles and peritoneal cavity. The efficacy of doramectin against Stephanurus dentatus in sows was 100% ( P

  • Sus scrofa domestica Endoparasitic Resistance in the Amazonasa
    Annals of the New York Academy of Sciences, 1996
    Co-Authors: Deborah Leal Rodrigues, Mario Hiraoka
    Abstract:

    The domestic pig (Sus scrofa domestica L.) has been wild breeding in the Varzea Amazonian Estuary area. Without dietary supplement or medical prevention, the pigs survive, bringing economic benefits to local peasants. Endoparasitic diseases generate economic losses because of neonatal death and clinical disease. We assessed the nematoda (O. Nematoda) and coccidia (O. Eucoccidia) parasitic level and tolerance in 75 pigs (0-18 months) from 35 families using the following methods: (i) larvae culture, (ii) Hoffman, (iii) Willis-Mollay (Hoffman 1987) and (iv) postmortem examinations. We identified Eimeria species Strongyloidea and S. ransomi present in 60% of the cases, giving a mean of 336 and 520 EPG (eggs per gram of feces), respectively. Culturing the larvae showed S. ransomi in 47% and Oseophagostomum sp. in 17% of the cases. We found Stephanurus dentatus and Macracanthorhynchus hirudinaceus adults in 77% and 23% of the postmortem tests, respectively. Pig resistance was demonstrated by lack of mortality and no clinical disease symptoms, in the presence of that high endoparasitic load.

  • High prevalence and intensity of Stephanurus dentatus in a population of wild boar (Sus scrofa) in south western Spain.
    Veterinary journal (London England : 1997), 2018
    Co-Authors: S. Moratal, R. Ruiz De Ybáñez, Patricia Barroso, José E. Granados, Ursula Höfle, Carlos Martínez-carrasco, Pelayo Acevedo, Joaquín Vicente
    Abstract:

    Abstract In the period from October 2016 to February 2017, the urinary tracts of 390 wild boar (Sus scrofa) from four areas of south central Spain (102 from Donana National Park; 150 from Sierra Morena and the Toledo Mountains; 84 from Sierra Nevada; 54 from Sierra de Cazorla, Segura y Las Villas Natural Park) were examined for the presence of adult specimens of Stephanurus dentatus (Nematoda: Strongyloidea). This parasite was only detected in the wild boar population of Donana National Park, with high prevalence (76.5 ± 4.2%; 78/102), mean intensity (43.2 ± 4.4) and mean abundance (33.1 ± 3.8). Juvenile wild boar had significantly lower prevalence and abundance than subadult and adult wild boar. The intensity of infestation was significantly higher in male than in female wild boar. The detection of a focus of S. dentatus infestation in the wild boar population in Donana National Park will provide further opportunities for understanding the epidemiology of this parasite.
