Adjuvants et stimulants de l'immunité: propriétés immunorégulatrices du muramyl-dipeptide, des corynébactéries anaérobies et du diéthyldithiocarbamate de sodium

Several immunomodulator agents may influence the host immune system. Among them there are the adjuvants and the immunostimulant agents. In this paper, after a brief review of the mechanism of action of adjuvants, we have described the adjuvant and stimulant properties of muramyl-dipeptide, anaerobic corynebacteria and sodium diethyldithiocarbamate.     

A hundred years of importation: The first animal quarantine station in North America; Lévis, Québec, 1876-1982

Quarantine, as a means of preventing disease importation, has been used for people and animals since the mid-19th century in Canada. The first animal quarantine facility in North America was established at Lévis, Québec in 1876. This quarantine station existed at Lévis until 1982 when it was closed and the function moved to Mirabel, Québec, near the International Airport. Veterinarians were in charge during the life of the Lévis Quarantine Station and some were also in charge of the Port of Quebec or a nearby District Office prior to the 1950's. In 1884 and 1886 the value of such a facility was illustrated in preventing the entry into Canada of contagious bovine pleuropneumonia and a vesicular disease. It was described in 1933 as “undoubtedly our most important quarantine station” and a year's operating costs as “trifling in comparison to losses which could occur if a foreign plague invaded this country”. This facility's history also illustrated the close veterinary and human medical cooperation during the early days of organized veterinary medicine in Canada. The station was an example for the establishment of other such facilities in North America.
