Hospitalized tuberculosis cases were observed, in the years 1982 and 1992. The number of cases decreased, from 148 in 1982 to 57 in 1992. This decrease was correlated to the decrease of the incidence rate in the area : 24,42/100 000 in 1982, 9,74/100 000 in 1992. The cases, according the age group, presented a bimodal distribution in 1992 with two peaks :before 34 years-old and after 65 years old. This kind of repartition did not exist in 1982. The importance of AIDS is, by now, minor (only 3 cases in 1992, none in 1992). The antibiotic resistance is not a problem (only 3 cases of combined resistance : streptomycin + isoniazid) and is not increasing since 1982. Those epidemiological datas should be reevaluated regularly, in order to observe a real evolution.

Des bacilles gram négatif du groupe M5 ont été retrouvés chez 6 patients mordus par un chien. Dans un autre cas, nous avons retrouvé un bacille du groupe EF4. Dans ces 7 cas, la symptomatolobie clinique était identique à celle décrite pour les pasteurelloses. Ces bactéries devraient être recherchées systématiquement dans toute morsure.

Nous rapportons l'isolement de Salmonella typhi et de bacille de Shiga polyrésistant chez une méme malade, de retour des Indes en novembre 1981. Dans ce contexte épidémiologique précis, les techniques bactériologiques utilisées pour le diagnostic devraient tenir compte de cette observation.

The authors analysing 553 serums, compare the results given by ELISA, in the diagnosis of human brucellosis, with four other usual serological tests : agglutination, rose Bengal plate agglutination test, complement fixation test, immunofluorescence. In the ELISA standard study and the research of specific M component, they can estimate, experimentally, the minimal absorbance necessary for concluding in positivity. They show the excellent specificity and sensitivity of this assay, its performances are almost the same as the immunofluorescence ones. Among 55 positive serums in one assay at least 83,6% are positive in both tests ELISA and IIF and 90,9% are detected by ELISA alone.
