Peracute diseased pigs die in &lt;24\u2009h with pneumonia. Neutrophils are the prominent innate immune cell in this infection that massively infiltrate the infected lung. Here we show that neutrophils release neutrophil extracellular traps (NETs) as response to\n                    <jats:italic>A.pp<\/jats:italic>\n                    infection. Numerous NET-markers were identified in bronchoalveolar lavage fluid (BALF) of\n                    <jats:italic>A.pp-<\/jats:italic>\n                    infected piglets in vivo, however, most NET fibers are degraded. Importantly,\n                    <jats:italic>A.pp<\/jats:italic>\n                    is able to enhance its growth rate in the presence of NETs that have been degraded by nucleases efficiently.\n                    <jats:italic>A.pp<\/jats:italic>\n                    itself releases no nuclease, but we identified host nucleases as sources that degrade NETs after\n                    <jats:italic>A.pp<\/jats:italic>\n                    infection. Furthermore, the nucleases of co-infecting pathogens like\n                    <jats:italic>Streptococcus suis<\/jats:italic>\n                    increase growth of\n                    <jats:italic>A.pp<\/jats:italic>\n                    in presence of porcine NETs. Thus,\n                    <jats:italic>A.pp<\/jats:italic>\n                    is not only evading the antimicrobial activity of NETs,\n                    <jats:italic>A.pp<\/jats:italic>\n                    is rather additionally using parts of NETs as growth factor thereby taking advantage of host nucleases as DNase1 or nucleases of co-infecting bacteria, which degrade NETs. This effect can be diminished by inhibiting the bacterial adenosine synthase indicating that degraded NETs serve as a source for NAD, which is required by\n                    <jats:italic>A.pp<\/jats:italic>\n                    for its growth. A similar phenotype was found for the human pathogen\n                    <jats:italic>Haemophilus (H.) influenzae<\/jats:italic>\n                    and its growth in the presence of human neutrophils.\n                    <jats:italic>H. influenzae<\/jats:italic>\n                    benefits from host nucleases in the presence of neutrophils. These data shed light on the detrimental effects of NETs during host immune response against certain bacterial species that require and\/or efficiently take advantage of degraded DNA material, which has been provided by host nuclease or nucleases of other co-infecting bacteria, as growth source.\n                  <\/jats:p>","DOI":"10.1038\/s41419-019-1895-4","type":"journal-article","created":{"date-parts":[[2019,9,10]],"date-time":"2019-09-10T08:02:54Z","timestamp":1568102574000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":51,"title":["Degraded neutrophil extracellular traps promote the growth of Actinobacillus pleuropneumoniae"],"prefix":"10.1038","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4516-7838","authenticated-orcid":false,"given":"Nicole","family":"de Buhr","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta C.","family":"Bonilla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jessica","family":"Pfeiffer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silke","family":"Akhdar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cornelia","family":"Schwennen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barbara C.","family":"Kahl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karl-Heinz","family":"Waldmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Valentin-Weigand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isabel","family":"Hennig-Pauka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7712-9767","authenticated-orcid":false,"given":"Maren","family":"von K\u00f6ckritz-Blickwede","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,9,10]]},"reference":[{"key":"1895_CR1","unstructured":"Gottschalk, M.
