Detection of Rickettsia felis, Rickettsia typhi, Bartonella species and Yersinia pestis in fleas (Siphonaptera) from Africa University of Antwerp

Hamza Leulmi, Cristina Socolovschi, Anne Laudisoit, Gualbert Houemenou, Bernard Davoust, Idir Bitam, Didier Raoult, Philippe Parola
Little is known about the presence/absence and prevalence of Rickettsia spp, Bartonella spp. and Yersinia pestis in domestic and urban flea populations in tropical and subtropical African countries. Methodology/Principal findings: Fleas collected in Benin, the United Republic of Tanzania and the Democratic Republic of the Congo were investigated for the presence and identity of Rickettsia spp., Bartonella spp. and Yersinia pestis using two qPCR ...

Molecular detection of **Rickettsia felis and Candidatus** rickettsia asemboensis in fleas from human habitats, Asembo, Kenya University of Antwerp

Ju Jiang, Alice N. Maina, Darryn L. Knobel, Anne Laudisoit, et al.
The flea-borne rickettsioses murine typhus (Rickettsia typhi) and flea-borne spotted fever (FBSF) (Rickettsia felis) are febrile diseases distributed among humans worldwide. Murine typhus has been known to be endemic to Kenya since the 1950s, but FBSF was only recently documented in northeastern (2010) and western (2012) Kenya. To characterize the potential exposure of humans in Kenya to flea-borne rickettsioses, a total of 330 fleas (134 pools) ...

The added value of a surveillance human biomonitoring program: The case of FLEHS in Flanders (Belgium) Departement of spatial development, environment, energy, climate, green economy, animal welfare

Hans Reynders, Ann Colles, Bert Morrens, Maja Mampaey, Dries Coertjens, Koppen Gudrun, Greet Schoeters, Ilse Loots, Hana Chovanova, Wim Winderickx, et al.
In 2002 the Flemish Government decided to initiate the Flem-ish Environment and Health Survey (FLEHS), an extended humanbiomonitoring (HBM) program to assess and monitor human expo-sure of the Flemish population to environmental pollution and itsimpact on public health. Flanders is a densely populated area inthe North of Belgium with intense traffic and widespread indus-trial and agricultural activities, which have a measurable impacton ...

The added value of a surveillance human biomonitoring program: the case of FLEHS in Flanders (Belgium) University of Antwerp

Hans Reynders, Ann Colles, Bert Morrens, Maja Mampaey, Dries Coertjens, Gudrun Koppen, Greet Schoeters, Ilse Loots, Hana Chovanova, Wim Winderickx, et al.
Since 2002, the Flemish Government decided to carry out the Flemish Environment and Health Survey (FLEHS), an extended human biomonitoring (HBM) program, which is integrated in the environmental health policy. Through the FLEHS studies, a vast amount of data such as biomarkers of exposure and effect, exposure effect associations, time trends and geographical differences, became available to the Flemish policy makers. In order to facilitate the ...

Stratification biomonitoring results FLEHS IV by socioeconomic status and origin Departement of spatial development, environment, energy, climate, green economy, animal welfare

Bert Morrens, Dries Coertjens, Ilse Loots, Ann Colles, Liesbeth Bruckers
This report presents biomarker data and questionnaire data from the youth campaign in the 4th cycle of the 'Flemish Environment and Health Study' (FLEHS IV, 2016-2020) stratified by indicators of socioeconomic status (SES) and origin of participants. Using univariate statistical analyses, we study social and ethnic gradients in exposure and effects of chemicals (biomarker data) and in behavior, perceptions and context variables around indoor ...

Multiplex genotyping as a biomarker for susceptibility to carcinogenic exposure in the FLEHS biomonitoring study Ghent University University of Antwerp

Hans B Ketelslegers, Ralph W Gottschalk, Gudrun Koppen, Greet Schoeters, Willy F Baeyens, Nicolas Van Larebeke, Joost van Delft, Jos C.S. Kleinjans
Cancer has been suggested to result from interactions between genetic and environmental factors, and certain subgroups in the general population may be at increased risk because of their relatively higher susceptibility to environmental carcinogens. The current study, part of a large biomonitoring study conducted in Flanders from 2002 to 2006 (The Flanders Environment and Health Survey), aims to determine these susceptible subpopulations based ...

FLEHS IV (2016-2020): Exposure effect associations Departement of spatial development, environment, energy, climate, green economy, animal welfare
