Effect of levamisole on immune function and reproductive performance in first-litter gilts
1988
Purswell, B.J. | Dawe, D.L. | Brown, J. | Williams, D.J.
First-litter commerical cross-bred gilts were treated with levamisole (1.5, 2.5, or 3.5 mg/kg of body weight) weekly during the last 4 weeks of gestation, because similar treatment of dairy heifers had improved postpartum maternal health and neonatal survival. In the gilts, differences in reproductive performance were not found on the basis of pig survival at birth, pig survival at weaning, birth weight, or weaning weight. Also differences between treated and control gilts were not found in response of circulating lymphocytes to mitogen stimulation (phytohemagglutinin A, concanavalin A, and pokeweed mitogen). In all gilts, the lymphocyte response to mitogen stimulation was decreased during the first week after farrowing.

1984
monoclonal antibodies derived from Trichinella spiralis-infected mice reacted with other swine parasites, one monoclonal antibody recognized antigenic determinant specific to T. spiralis, isolation of this antigen by monoclonal antibody-affinity chromatography, use of antigen in enzyme-linked immunosorbent assay eliminated false-positive reactions with serum of healthy swine and detected all pigs infected with T. spiralis

1984
Conlogue, G. | Foreyt, W.J. | Wescott, R.B.
Eimeria spp., calves (exper.) treated with lasalocid (Bovatec) or decoquinate (Deccox) and premunized did not develop diarrhea, calves premunized but not treated were no more resistant to challenge than nonpremunized calves, premunization alone cannot be expected to prevent coccidiosis when animals are exposed to large numbers of oocysts

1984
Eckblad, W.P. | Stiller, D. | Woodard, L.F. | Kuttler, K.L.
tick infestations did not cause suppressed immune responses to Anaplasma marginale vaccination in calves, anaplasmosis did not prevent calves from developing resistance to tick reinfestation which was accompanied by immediate hypersensitivity reactions against homologous tick extracts, Dermacentor albipictus did not seem to share common antigenic determinants with Boophilus microplus

1984
Glickman, L.T. | Grieve, R.B. | Breitschwerdt, E.B. | Mika-Grieve, M. | Patronek, G.J.
Dirofilaria immitis, dogs, enzyme linked immunosorbent assay used in combination with radiographic examination, Knott test, blood cell counts, and fecal examinations to study seroepizootiology of canine heartworm infection and to investigate the influence of several host and environmental factors (age, sex, living conditions, breed, hair coat length) and chemoprophylaxis (diethylcarbamazine) on serological patterns in dogs; other nematodes also identified
