Enteric pathogenic bacteria and resistance gene carriage in the homeless population in Marseille, France.

We aimed to assess the prevalence of pathogenic bacteria and resistance genes in rectal samples collected among homeless persons in Marseille, France. In February 2014 we enrolled 114 sheltered homeless adults who completed questionnaires and had rectal samples collected. Eight types of enteric bacteria and 15 antibiotic resistance genes (ARGs) were sought by real-time polymerase chain reaction (qPCR) performed directly on rectal samples.

Epidemiological serosurvey and molecular characterization of sexually transmitted infections among 1890 sheltered homeless people in Marseille: Cross-sectional one day-surveys (2000-2015).

Objectives: We observed the prevalence and distribution of potential risk factors for sexually transmitted infections (STIs) among Marseille homeless population.

Methods: Over the 2000-2015 period, we enrolled 1890 sheltered homeless adults and collected serum samples. Markers of hepatitis B and C viruses (HBV, HCV) and Treponema pallidum were searched using the CMIA testing.

Epidemiological serosurvey of vector-borne and zoonotic pathogens among homeless people living in shelters in Marseille: cross-sectional one-day surveys (2005-2015).

Homeless people are often exposed to unhygienic environments as well as to animals carrying arthropods which both transmit zoonotic infections and human louse-borne pathogens. We attempted to determine the prevalence of antibodies against several vector-borne and zoonotic pathogens among homeless adults living in Marseille. During the 2005-2015 period, we collected sera samples from 821 homeless adults living in shelters.
