  abstract = {{L}eptospirosis is a waterborne zoonosis (60,000 infections and 1 million deaths annually). {K}nowledge about the disease in the urban context is surprisingly rare, especially in {A}frica. {H}ere, we provide the first study of leptospires in waterswithin an {A}frican city. {A} simple centrifugation-basedmethodwas developed to screenwaterborne leptospires fromremote or poorly areas. {M}ajor ions, trace elements, stable isotopes and pathogenic {L}eptospira were then seasonally investigated in 193 water samples from three neighborhoods of {C}otonou ({B}enin) with different socio-environmental and hydrographic characteristics. {F}irstly, no leptospire was detected in tap waters. {S}econdly, although surface contamination cannot be excluded, one groundwaterwellwas found leptospire positive. {T}hirdly, pathogenic {L}eptospira mainly contaminated surface waters of temporary and permanent ponds (9.5% and 27.3% of total prevalence, respectively). {I}sotopic signatures suggest that leptospires occurred in pondwaters formed at the beginning of the rainy season following low to moderate rainfall events. {N}evertheless, {L}eptospiracontaining waters possess physico-chemical characteristics that are similar to the spectrum of waters sampled throughout the three sites, thus suggesting that {C}otonou waters are widely compatible with {L}eptospira survival. {T}he frequent contact with water exposes {C}otonou inhabitants to the risk of leptospirosis which deserves more attention from public health authorities.},
