Horizontal transmission from the body louse vector (Pediculus humanus humanus) to a human host occurs through contact with infectious louse feces containing a high concentration of the bacteria. However, questions have remained about whether vertical transmission from infected vectors to their progeny, which could significantly influence the dynamics of transmission to humans, occurs in body lice. To address this subject, we performed a series of controlled laboratory experiments that examined the presence of B. quintana on the surface of and within eggs produced by female body lice that were provisioned multiple infectious blood meals to recapitulate the natural pathogen acquisition process. Our results demonstrate that B. quintana DNA can be detected from the surface of eggs by qPCR due to vertical transfer of infectious feces to the egg sheath during or after oviposition. However, viable B. quintana could not be cultured from the hemolymph of adult female lice or from within eggs that were surface sterilized, indicating a lack of true transovarial transmission. Based on this evidence, vertical transfer of B. quintana from infected adult lice to their eggs probably has a limited impact on the dynamics of transmission to humans.<\/jats:p>","DOI":"10.1093\/femspd\/ftac028","type":"journal-article","created":{"date-parts":[[2022,7,8]],"date-time":"2022-07-08T23:26:58Z","timestamp":1657322818000},"source":"Crossref","is-referenced-by-count":3,"title":["Examination of vertical transmission of <i>Bartonella quintana<\/i> in body lice following multiple infectious blood meals"],"prefix":"10.1093","volume":"80","author":[{"given":"Lauren","family":"Kress","sequence":"first","affiliation":[{"name":"Sanford School of Medicine, Division of Basic Biomedical Sciences, University of South Dakota , Vermillion, SD, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rashaun","family":"Potts","sequence":"additional","affiliation":[{"name":"Sanford School of Medicine, Division of Basic Biomedical Sciences, University of South Dakota , Vermillion, SD, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7607-3220","authenticated-orcid":false,"given":"Jose E","family":"Pietri","sequence":"additional","affiliation":[{"name":"Sanford School of Medicine, Division of Basic Biomedical Sciences, University of South Dakota , Vermillion, SD, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2022,7,8]]},"reference":[{"key":"2022081714474785900_bib1","doi-asserted-by":"crossref","first-page":"14","DOI":"10.1645\/19-132","article-title":"Microbiome differences between human head and body lice ecotypes revealed by 16S RRNA gene amplicon sequencing","volume":"106","author":"Agany","year":"2020","journal-title":"J Parasitol"},{"key":"2022081714474785900_bib2","doi-asserted-by":"crossref","first-page":"474","DOI":"10.3389\/fcimb.2019.00474","article-title":"Where are we with human lice?
