Hematologic and coagulation abnormalities in acute bovine sarcocystosis
1984
Frelier, P.F. | Lewis, R.M.
acute Sarcocystis cruzi infection in calves (exper.), hematologic studies support claim that anemia is an extravascular hemolytic event, probably with immunologic basis; coagulation studies indicate that endothelial S. cruzi schizonts may cause endothelial damage, resulting in coagulation abnormalities that include disseminated intravascular coagulation

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
Davey, R.B. | Ahrens, E.H.
Boophilus microplus, B. annulatus, Hereford heifers (exper.), permethrin or fenvalerate applied as sprays, both pyrethroids could provide adequate reduction in control programs however both acaricides failed to provide the necessary reduction to achieve complete elimination

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
