The diagnosis of salmonellosis is made by isolation of the germ, by stool culture but which sometimes remains negative and especially by blood culture. The serodiagnosis of Widal and Felix makes it possible to detect in the blood the antibodies directed against agglutinins O and H.
The treatment of minor forms of salmonellosis is based on symptomatic treatment, ie analgesic and rehydration. In severe forms, antibiotic treatment is indicated.
Treatment of typhoid forms is based on antibiotic therapy. Because of the emergence of a resistant strain, antibiotic therapy should be adapted to the antibiogram (study of the sensitivity of the isolated bacterial strain to the different antibiotics).
In all cases, prevention plays a vital role.
The prevention of minor salmonellosis is based on good food cooking, keeping eggs at the same temperature, washing hands after contact with animals but also after handling risky foods.It is recommended for people at risk not to consume raw or undercooked eggs (elderly, pregnant women, immunocompromised, young children).
The prevention of the typhoid form is based on the control of the faecal peril and the carrying out of a vaccination for the travelers going to endemic zone. This vaccination confers a protection of 3 years. It only protects against Salmonella Typhi and its protection rate is 60% in endemic areas.
