    Bone and joint infections (BJIs) are increasingly prevalent in tropical regions, with Gram-negative bacilli (GNB) being the predominant pathogens identified.

  • 2

    A study at Guadeloupe University Hospital found that GNB accounted for 41% of isolates in BJIs, with significant resistance patterns affecting treatment options.

  • 3

    Cefazolin showed limited effectiveness against pathogens in native septic arthritis, with higher efficacy observed for cefepime and piperacillin-tazobactam.

  • 4

    Factors such as history of bite/scratch wounds and contact with soil/vegetation were independently associated with GNB infections in BJIs.

    The study emphasizes the need for local surveillance systems to guide empirical antibiotic treatment strategies in tropical settings.
