Physiopathologie et thérapeutique de l'utérus en période puerpérale chez la vache laitière: revue

Accurate diagnosis and effective therapeutics of uterine pathologies in cattle represent some of the daily preoccupations for the veterinarians involved in herd health medicine. A rational approach requires a competence based on fundamental and clinical knowledge.

The physiological aspects of the uterine involution in cattle are reviewed with emphasis about the in utero bacteriological dynamic and the endocrinological evolution during this period. The pathogenesis of uterine pathologies is discussed following new research results and new knowledge on the mechanisms of uterine defense. The value and limitations of the clinical diagnosis is briefly reviewed. The therapeutics of uterine pathologies is debated in relation with the pathophysiology of the uterine involution and with the rational of the traditional and new concepts of the treatment of the postpartum uterine pathologies.

Analogie entre les rétrovirus humains lymphotropes et les rétrovirus des grands animaux

The family Retroviridae comprises some fifty viruses in three subfamilies: Oncoviridae, Lentiviridae and Spumaviridae. A better understanding of retroviral pathobiology has resulted from the rapid developments in knowledge of the molecular biology of normal and cancerous cells as well as retroviruses. Genomic relatedness was found between two human T cell leukemia viruses and bovine leukemia virus; similarly, some relatedness appears possible between human AIDS (acquired immunodeficiency syndrome) virus and lentiviruses of large animals. Because of their genomic relatedness, retroviruses from man and animals could theoretically form recombinants during in vitro manipulation. Therefore persons who work with retroviral materials should follow established laboratory practices to control infectious agents.
