Cholera

•  Clinical-epidemiologic syndrome

•  Vibrio cholerae, usually O1 with CTX toxin

•  watery diarrhea (rice water) that rapidly lead to dehydration

•  Explosive outbreaks/true pandemics

•  Often in the wake of wars ,civil conflicts, climatic events, famine, refugees

•  1.03 billion people at risk (Asia and Africa)

•  Estimated 2.86 million cases and 95,000 deaths/year (Ali et al. Plos NTD 2015)

•  Treatment: rehydration +++ and antibiotics

History

Classical •  1817-1823 : Asia, Middle East, East Africa •  1829-1851 : Global •  1852-1859 : Global •  1863-1879 : Global •  1881-1896: Global •  1899-1923 Asia, Middle East, Eastern Europe

1st-6th pandemic

El Tor 1961, Indonesia

7th pandemic

R. Koch F. Pacini

Vibrio cholera Vibrio comma 1883, Egypt 1854, Italy

Classical laboratory methods

•  O antigen serogrouping (O1, O139, O37, …) •  Biotyping (El Tor vs Classical) •  O1 serotyping (Ogawa, Inaba, Hiwojima) •  Phage typing •  Multilocus enzyme electrophoresis (MLEE) •  Ribotyping •  Pulsed-field gel electrophoresis •  ctxB (B subunit of cholera toxin) RFLP or sequencing •  tcpA (toxin coregulated pilus A) sequencing •  Sequencing of other virulence genes ….. •  Multiple loci VNTR analysis (MLVA)

Confusion !!!

Vc O1 El Tor (ET) genomes •  N16961 (Heidelberg et al., Nature 2005)

4.03 Mb, 3885 CDSs 2 circular chromosomes (2.96 Mb, 1.07 Mb) CTXΦ phage on CHR1 Large integron island (125 kb) on CHR2

•  22 other genomes, including 12 O1 ET (Chun et al. PNAS 2009)

•  7P isolates contain VSP-1 and VSP-2 •  CTXΦ can be carried on CHR2

Bangladesh 1975

73 GI identified

Page 6: The use of genomics for understanding introduction and

136 global isolates sequenced including 123 O1 ET

A pioneer genomic study Lineage L2 El Tor (7th pandemic)

•  3 waves •  Role of the Bay of Bengal •  Identification of intercontinental transmission events

Lineage L1 Classical (1st to 6th pandemic)

Page 7: The use of genomics for understanding introduction and

•  2005 : incidence in sub-Saharan Africa was 95 and 16,600 times higher than that in Asia and Latin America, respectively

•  2005 : CFR in sub-Saharan Africa (1.8%) was 3 times higher than that in Asia (0.6%); no cholera deaths were reported in Latin America.

•  2007-2012, >95,000 cases/y notified by >20 countries in Africa

Why a genomic study on cholera in Africa ?

Page 8: The use of genomics for understanding introduction and

28 African isolates studied but all but one from East Africa : Angola 1989 (n=1); Djibouti 2007 (n=3); Kenya 2005-2007 (n=17); Mozambique 1991, 2005 (n=6); Tanzania 2009 (n=1).

Objectives of our study

Analysis of 1,070 genomes, including 631 from Africa

(45/54 countries)

•  Identify the introduction and transmission routes of V. cholerae O1 ET in Africa, 1970-2014

•  Linkage between the different outbreaks •  Emergence of antimicrobial resistance

742 sequenced isolates (558 from IP) 328 published genomes

Methodology

1. Illumina sequencing (75-250 bp PE short reads) 2. Mapping against reference genome N16961 (CHR1 and CHR2) 3. SNPs calling and filtering (SMALT), assembling (SPAdes) 4. Phylogenetic and phylogeographic analyses and estimatation of the divergence times of the different lineages/strains (RAxML after Gubbins, Path-O-Gen, BEAST) 5. Extraction of antibiotic resistance genes and their genetic support (Resfinder on read assemblies, PacBio sequencing)

Conclusions

•  Iterative introductions of cholera to Africa from Asia (arguing against an environmental reservoir of Vibrio cholerae O1)

•  Separated Western and Eastern African foci

•  Role of the Middle East as a springboard (in particular in 1970) but recently direct transmission from South Asia

•  Confirmation of the West African origin of the South American outbreak of

1991 •  Accumulation of chromosomally-encoded multidrug resistance elements,

as observed previously with human pathogens Shigella dysenteriae type 1 and Salmonella Typhi H58
