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.     

Les milieux de contraste en radiographie: propriétés, applications, indications et contre-indications, I

The author describes the contrast media most commonly used in veterinary radiography. Emphasis is given to its physical properties and applications rather than examination techniques. There is also a reminder of the indications and contraindications for each examination using a given contrast medium.     

Entéropathie, avec perte de protéines, secondaire à une lymphangiectasie intestinale, chez trois chiens

Protein-losing enteropathy secondary to intestinal lymphangiectasia in three dogs

Three cases of protein-losing enteropathy secondary to intestinal lymphangiectasia in the dog are presented.

In the three cases, common clinical findings were nonresponsive diarrhea and weight loss. Subcutaneous edema was observed in case 1. Polyphagia and polydipsia were evident in cases 2 and 3.

Serum examinations revealed low values of protein with a normal albumin/globulin ratio. There was histopathological evidence of dilatation of lacteals, as well as plasma cell and lymphocyte infiltration in the small intestine.

In the three cases, a corticotherapy was instituted and gave good results.

Incidence of canine rabies in N'Djaména, Chad

This work describes for the first time the incidence risk of passively reported canine rabies, and quantifies reported human exposure in N'Djaména (the capital of Chad). To diagnose rabies, we used a direct immunofluorescent-antibody test (IFAT). From January 2001 to March 2002, we were brought 34 rabies cases in dogs and three cases in cats. Canine cases were geographically clustered. The annual incidence risk of canine rabies was 1.4 (95% CI: 1.2, 1.7) per 1000 unvaccinated dogs. Most of the rabid dogs were owned-although free-roaming and not vaccinated against rabies. Most showed increased aggressiveness and attacked people without being provoked. Eighty-one persons were exposed to rabid dogs and four persons to rabid cats (mostly children<15 years old). Most of the exposed persons were neighbours or family members of the animal owner. Most exposures were transdermal bites, but nearly half of all exposed persons did not apply any first wound care or only applied a traditional treatment. In N'Djaména, humans are often exposed to canine rabies but do not use the full-course post-exposure treatment and wound care is insufficient. Most rabid dogs would be accessible to parenteral vaccination. Pilot vaccination campaigns are needed to determine the success of dog mass vaccination in N'Djaména as a way to prevent animal and human rabies.
