    Notes: The effect of chopping temperature and time on the stability of white and dark turkey meat emulsions was determined. White meat emulsions remained stable over extended chopping times in a 1.5°C temperature environment. When chopped in room temperatures, the white meat sausages became very unstable after 18.2°C and were most stable at 12.8°C. Dark meat sausages were significantly more unstable than white meat emulsions under both chopping environments. Tensile strength of cooked white and dark meat emulsions declined with increases in chopping temperature. When prepared in l.5°C surroundings, tensile strength changes were notable only after 10 min chopping for white meat. Dark meat sausage tensile strength seemed unaffected by chopping time. In contrast to earlier red meat emulsion work, protein denaturation was indicated to occur in turkey meat emulsions prepared under both cold and room temperature environments. Decreases in soluble proteins due to increased chopping occurred under both conditions. Protein denaturation is believed to be partially responsible for emulsion breakdown. Dark meat showed more protein denaturation than white meat emulsions. Photomicrographs of histologically prepared meat emulsions showed disruption of the protein-fat globule interface as a result of increased chopping or temperature, or both. Coalescence and emulsion breakdown occurred at end-point chopping temperatures similar to those reported by red-meat workers.

    Description / Table of Contents: Résumé Deux groupes de chèvres adultes (mâles castrés, 3 animaux par groupe) ont été infectés par voie intraveineuse avec la souche vaccinale Ball 3 deCowdria ruminantium, et traités avec une oxytetracycline à longue action lors de l'application des signes cliniques dix jours plus tard. Cinq semaines après la vaccination, un groupe a été éprouvé avec une souche antillaise (Gardel) et l'autre groupe avec une souche ouest-africaine (Mali) deC. ruminantium. Les animaux contrôlés, non vaccinés, infectés soit par la souche Gardel, soit par la souche Mali, sont morts. Les animaux vaccinés, éprouvés avec la souche Gardel ont réagi mais ont survécu. Les trois animaux éprouvés avec la souche Mali ont aussi réagi et deux sont morts de heartwater.
    Abstract: Resumen Se infectaron tres grupos de machos cabríos castrados vía intravenosa (tres cabras/grupo), con la vacuna Ball 3 deCowdria ruminantium. Los animales se trataron posteriormente con tetraciclina LA, diez días después al comienzo de la enfermedad clínica. Cinco semanas después de la vacunación, un grupo se descargó con la cepa Caribeña (Gardel) y el otro grupo, con la cepa Africana Occidental (Malí) deC. ruminantium. Los controles no vacunados, infectados con las cepas Gardel y Malí, murieron. Todos los animales vacunados que recibieron la descarga con la cepa-Gardel, sobrevivieron. Los tres animales que recibieron la descarga con la cepa Malí reaccionaron también, muriendo dos de ellos.
    Notes: Summary Two groups of castrated male adult goats (three goats/group) were infected intravenously with the Ball 3 vaccine strain ofCowdria ruminantium and treated with long-acting oxytetracycline at the onset of clinical disease 10 days later. Five weeks post-vaccination one group was challenged with a Caribbean isolate (Gardel) and the other group with a West African isolate (Mali) ofC. ruminantium. Non-vaccinated controls infected with either the Gardel or Mali isolate died. All of the vaccinated animals challenged with the Gardel strain reacted and survived. The three vaccinated animals challenged with the Mali isolate also reacted and two died of heartwater.

    African swine fever virus specific porcine cytotoxic T cell activity (1993)

    Notes: Summary African swine fever virus (ASFV) specific, cytotoxic T lymphocyte (CTL) activity has been studied in a protection model in which SLA inbred miniature swine are experimentally inoculated with a naturally occurring, non-fatal ASFV isolate (NHV). Peripheral blood mononuclear cells (PBMC) from such infected swine show significant activity in CTL assays, using cultured ASFV-infected porcine blood derived macrophages as target cells. This CTL activity is elicited from PBMC by in vitro restimulation of effector cells with low doses (multiplicity of infection=0.1) of the homologous virus isolate for 48 to 72 h. For SLAc/c effectors, this CTL activity appears to be SLA class I restricted because (1) blocking target cell antigens with monoclonal antibodies (mAb) against SLA class I antigens causes a major reduction in CTL activity; (2) there is preferential lysis of SLA class I matched, ASFV infected targets; and (3) depletion of effector cells with CD8 specific mAb and complement causes a reduction in CTL activity. The CTL activity is ASFV specific for all pigs tested in that infected macrophages are preferentially lysed as compared to normal (non-infected) cultured macrophages or macrophages infected with hog cholera virus (HCV). Lysis of macrophages infected with different ASFV isolates revealed that there is marked lysis of macrophages infected with the virulent L 60 isolate but less lysis of macrophages infected with the DR-II and Tengani isolates. In summary, our data show that ASFV specific CTL activity is triggered in swine infected with the NHV ASFV isolate.

    Cell culture adaptation and propagation of a reovirus-like agent of calf diarrhea from a field outbreak in nebraska (1972)

    Notes: Summary The Nebraska calf diarrhea viral (NCDV) agent was successfully adapted and propagated in several cell culture systems. Criteria of propagation were: production of a cytopathic effect, specific fluorescence, interference with cytopathogenicity of another virus, infection of neonatal calves, and identification of the NCDV agent by electron microscopy (EM) or immuno-electron microscopy (I-EM). The EM and I-EM techniques proved to be valuable diagnostic aids for detecting NCDV disease in affected calves. Morphologically, the NCDV agent resembled the reoviruses. Resistance to lipid solvents and fluorocarbon further related NCDV to this group. The NCDV agent, however, was serologically unrelated to reoviruses so a “reovirus-like” classification for this virus was suggested.
