Species and serovars of the genus Listeria lsolated from different sources in Brazil from 1971 to 1997

Using phenotype techniques, characterization was made to species and serovar of 3,112 strains of Listeria, isolated from different sources of infection such as human (247-7.9%) and animals (239-7.6%), as well as from various routes of infection, including food (2,330-74.8%) and environmental constituents (296-9.5%), all coming from different regions of the country and collected during the period 1971-1997. The following species were recovered in the cultures analysed: L. monocytogenes (774-24.8%), L. innocua (2,269-72.9%), L. seeligeri (37-1.1%), L. welshimeri (22-0.7%), L. grayi (9-0.2%), and L. ivanovii (1-0.03%). L. monocytogenes was represented by ten serovars, the most prevalent being 4b (352-11.3%), 1/2a (162-5.2%), and 1/2b (148-4.7%). The predominant serovar in L. innocua was 6a (2,093-67.2%). Considerations about laboratory methods for diagnosis and epidemiological aspects are presented on the basis of the results obtained.

Report of the Second Satellite Symposium on Ultrasound in Schistosomiasis

A group of experts on schistosomiasis and ultrasonography discussed the experiences and results obtained with the Niamey-Belo Horizonte Protocol on Ultrasonography in Schistosomiasis. A series of recomendations about qualitative and quantitative data obtained by ultrasound in studies performed in Africa and Brazil are presented. Imunological, genetic and epidemiological studies must rely on ultrasound for the identification of patients with periportal thickening/fibrosis.

Trends in violent deaths among young people 10-24 years old, in Switzerland, 1969-1997.

PURPOSE: To assess violent death rates and trends between 1969 and 1997 among young people aged 10-24 years old in Switzerland. METHODS: Total causes of death, all external causes of injuries, traffic injuries, suicides and overdoses were retrieved from the databank of the Swiss Federal Statistical Office (SFSO), using the eighth and tenth revisions of the International Classification of Diseases (ICD). Mortality rates per 100,000 individuals were computed by gender and by age (10-14, 15-19, 20-24) using census records as denominators. RESULTS: In 1995-1997, violent deaths represented the primary cause of fatalities among young people. Rates of violent death were much higher among males than among females, with a ratio of 3.5:1 in 1995-1997 and also became increasingly elevated from the age range of 10-14 to 20-24 years (1.9:1-4.4:1). In 1995-1997, violent deaths accounted for 66% (n = 1221) of all fatalities among young people. Among violent deaths, 36% were due to traffic injuries, 13% to other types of injuries, 32% to suicide, 15% to overdoses, 3% to homicides and 1% to undetermined intent. Between 1969 and 1997, rates of traffic injuries decreased in both genders and in the three age groups considered, while rates of suicide remained stable and rates of overdoses stabilised during the nineties after a sharp increase during the eighties. CONCLUSION: Although violent deaths in Switzerland have become significantly less frequent over the last 30 years, they still represent the single greatest cause of fatalities among young people and, as such, constitute a major public health challenge.

The initial epidemiological studies in the low endemicity schistosomiasis area in esteio, Rio Grande do Sul, the southernmost Brazilian State, 1997 to 2000

Nor Biomphalaria glabrata neither Schistosoma mansoni were reported from Rio Grande do Sul, the southernmost Brazilian state before 1997. Their detection next to the Sinos River, Esteio, confirmed predictions of schistosomiasis expansion to the south. Parasitological examinations both in snails and fecal samples from the human population were performed from 1997 to 2000. The last 3 out of 5 surveys were performed after a preliminar serological screening procedure in a risk group identified at a population census. A total of 11 infected individuals were found infected and snails from 2 different sites were positive for S. mansoni. Samples from these 2 and other sites were identified as B. glabrata. Egg counts in feces were below 1 per gram in 6 out of 11 patients. Some socio-cultural perceptions of water contact activities next to the Sinos River may cause difficulties to control efforts, but they also may be partially acting against a very rapid increase in transmission intensity. The southernmost schistomiasis mansoni foci in Americas rise the alert for its ongoing expansion.
