Transposon Tn5 mutagenesis of Brucella abortus [PDF]
Infection and Immunity, 1987 We demonstrate that transposon-mediated mutagenesis can be used to construct mutations in the pathogen Brucella abortus. We have used both a plasmid and a bacteriophage to introduce either Tn5 or Tn5 lac into the Brucella chromosome. B. abortus is naturally sensitive to kanamycin.

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.Marine brucellosis shows high prevalence in cetaceans (52%), followed by other marine mammals (30%) and pinnipeds (18%), indicating species‐specific susceptibility. These findings highlight the need for targeted surveillance and diagnostic strategies to mitigate ecological and zoonotic risks.
