[Toxoplasma infestation: prevalence, risk of congenital infection and development in Geneva from 1973 to 1987].

Assessment of the risk of toxoplasma infection during pregnancy in the female population of the Geneva area, and of the risk of congenital toxoplasmosis, has shown 9 cases of toxoplasmosis for 1000 pregnancies and 3.5 congenital infections for 1000 newborn infants. These results show that the prevalence of toxoplasma infection has been decreasing constantly during the 15 years of study, but that the risk of infection during pregnancy and of congenital infection has remained steady.

[Non-tuberculous Mycobacteria: epidemiologic importance and current pathogenicity].

The non-tuberculosis mycobacteria are reviewed, with emphasis on the epidemiological and pathogenic importance of these organisms when the prevalence of tuberculosis diminishes. The increasing proportion of weak reactions to human tuberculin observed between 1975 and 1981 among school children of the Canton of Geneva and the relatively high number of non-tuberculosis mycobacteria demonstrated in human material between 1979 and 1981 in this Canton suggest that these mycobacteria also play a role in this country.

[Multicenter study on the status of antibiotic and chemotherapy resistance in Switzerland 1979].

In 1979 a three-month multicentre study of resistance of bacteria isolated from humans and animals was carried out in Switzerland with the participation of 22 institutes and laboratories. A total of 23,852 antibiograms were evaluated concerning the following bacteria: Escherichia coi, Klebsiella pneumoniae, Salmonella sp., Serratia marcescens, Proteus (indole-negative), Proteus (indole-positive), Pseudomonas aeruginosa, Staphylococcus aureus, and enterococci (streptococci of Group D). 95.5% of the strains were isolated from human material, almost half being isolated from urine. The remaining 4.5% were obtained from animal material, more than half being isolated from the milk of cows with mastitis. Although the various institutes and laboratories did not use a uniform, standardized method, the results are closely in line with those of similar studies carried out earlier in Switzerland, Germany, Austria and the USA. No pronounced trend in the direction of increased resistance is observable.

[Clinical suspicion of tuberculosis and non-tuberculous mycobacteria].

During the year 1979, 28 out of 95 patients with positive culture for acid-fast bacilli exhibited non-tuberculous mycobacteria (29.5%). In 15 cases the radiological and clinical findings were consistent with the diagnosis of tuberculosis, but only in one case (cutaneous lesion) was the pathology due to the mycobacteria isolated whereas in all others the bacteria was a saprophyte. This study suggests that non-tuberculous mycobacteria may be more frequent than expected in our region, and demonstrates the importance of their precise identification in order to stop their treatment. Nevertheless, in case of doubt and until identification results are obtained, such patients must be treated as probable tuberculosis cases.
