Construction of saturated Tn-Seq libraries of <i>Brucella abortus</i> S19 for transposon insertion and effective density analysis across stress conditions

<i>Brucella abortus</i> is a globally significant zoonotic pathogen. To explore the functional relevance of its genes in acidic, oxidative, and antimicrobial stress conditions, we constructed high-density transposon sequencing libraries in the attenuated <i>B. abortus</i> S19 strain. Here, we present the results and analysis of transposon insertion frequencies and effective densities.
