Monoclonal antibody-purified antigen for the immunodiagnosis of trichinosis
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

1984
Ooi, H.K. | Oku, Y. | Kamiya, M. | Ohbayashi, M.
Trichinella spiralis, day-old chicks (exper.), most worms expelled, some matured in intestine and produced larvae which penetrated muscles, little or no development there, followed by death and degeneration, viability of larvae from chickens confirmed by mouse infection

1984
Wescott, R.B. | Farrell, C.J. | Shen, D.T.
Fasciola hepatica, natural infections of cattle surveyed by enzyme-linked immunosorbent assay (ELISA), results compared with those obtained by fecal examination, advantages and limitations of ELISA for diagnosis: Washington

1984
Klesius, P.H. | Washburn, S.M. | Ciordia, H. | Haynes, T.B. | Snider, T.G., III.
Ostertagia ostertagi, calves (nat. and exper.), type I ostertagiasis, assay of lymphocyte reactivity to O. ostertagi L3 antigen and phytohemagglutinin, possible lack of genus specificity to antigen shown by reaction using lymphocytes from Cooperia punctata-infected calves, kinetics of lymphocyte reactivity showed transient nonspecific suppression of cell-mediated immune responses during prepatent periods of type I ostertagiasis, immunosuppression phenomenon may have role in O. ostertagi pathogenesis and development of immunity
