The results suggest that HHV8 infection is widespread in Western Sicily. The high seroprevalence in individuals with high risk sexual activity point to the role of sexual behaviour in the transmission of the infection in adults, whereas the detection of antibodies in younger population (under 16 years old) is suggestive of a non-sexual route of transmission, probably occurring during childhood by close personal contact.
Although the level of awareness among hairdressers about HIV, hepatitis and risk of transmission was good, there were some unsafe practices that may lead to infections due to blood-borne viruses. The present article highlights the need to improve specific health messages in media campaigns carried out to general population, diffusing more appropriate educational materials for salons and organizing obligatory refresher courses for the hairdressing sector.
Background: The presence of Giardia was investigated along the Oreto river between January 2008 and May2009 with the aim of understanding the source of contamination by molecular typing of cysts.Methods: A total of 38 water samples (10 collected from the river mouth, 24 from the whole Oreto basin and4 sewage samples from the Monreale treatment plant) were processed. In addition, 22 faecal samples oflivestock living close to the Oreto area, were analyzed. The presence of Giardia was determined byimmunofluorescence assay and their genetic characterization was achieved by a nested PCR assay targetingthe triosephosphate isomerase gene.Results: All water samples from the river mouth were positive for Giardia, even if the concentration of cystsfluctuated considerably among sampling occasions. Our investigation showed that the Vadduneddu andAltofonte torrents, two influents of the river, were the principal sources of contamination. Moreover, thegenotypes of Vadduneddu torrent were the same as those detected in human wastewater taken from theactivated sludge plant of Monreale city. Assemblages A and B were found in water samples with apredominance of Assemblage A, subtype AII. Assemblage E was only found in a single calf isolate.Conclusions: The data show that the high cyst counts regularly detected in the Oreto river are due tocontamination with wastewater of human origin. This finding is relevant for public health, particularlybecause river water is used for agricultural purposes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
