Unlabelled: The presence of Kerstersia gyiorum in lower leg wounds has been reported in case studies from several countries.
Objective: This study evaluated the antimicrobial susceptibility profile of K gyiorum isolated from a chronic wound.
Methods: An 85-year-old woman with chronic venous insufficiency presented to an intermediate care unit in Niteroi City, Rio de Janeiro, Brazil, with an instep chronic wound of 14 cm² with wound duration of 6 months. K gyiorum was identified by matrix-assisted laser desorption ionization-time of flight, confirmed by 16S rRNA partial sequence analysis, and classified as resistant for ciprofloxacin by reagent strips(minimum inhibitory concentration [MIC] = 32 µg/mL) and the broth macrodilution method (MIC = 8 µg/mL). Intermediate resistance for ciprofloxacin was verified by microscan (MIC = 2 µg/mL).
Conclusion: The authors identified the first, to their knowledge, lower leg wound with K gyiorum in Brazil and verified that it was ciprofloxacin resistant.

, a rare Gram-negative pathogen first identified in 2003, belongs to the family. Although infrequently reported, it has been isolated from various clinical infections, including wounds, and respiratory tract infections. Our case report highlights an unusual presentation of in a 13-year-old girl with a complex medical history, associated with external ear pressure ulcers.

is a Gram-negative bacterium found in various animals, including humans, where it has been associated with various infections. Knowledge of the basic biology of is essential to understand the evolutionary strategies of niche adaptation and how this organism contributes to infectious diseases; however, genomic data about is very limited, especially from non-human hosts. In this work, we sequenced 12 genomes isolated from healthy free-living brown-throated sloths () in the Parque Estadual das Fontes do Ipiranga (São Paulo, Brazil), and compared them with genomes from isolates of human origin, in order to gain insights into genomic diversity, phylogeny, and host specialization of this species.

With the development of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and 16S ribosomal RNA (rRNA) gene sequencing, increasing numbers of new microorganisms are being discovered. In this report, was isolated for the first time from the sputum of two elderly patients with neurodegenerative disease, and integrated traditional Chinese and Western medicine was used for treatment. The bacteria's growth characteristics, biochemical reaction characteristics, sensitivity to antibiotics, and the patients' treatment are described, with a review of previous reports.

Whole-genome sequence data for clinically relevant Gram-negative bacteria from the African continent are scarce. In this report, we present the draft genome sequence data and antibiograms of four species, namely, Kerstersia gyiorum, Providencia vermicola, Providencia stuartii, and Alcaligenes faecalis, that were recovered from human soft tissue biopsy samples.

Bordetella trematum and Kerstersia gyiorum are rare gram-negative bacilli that are not frequently detected in human infections. In this report, we describe a case of a 48-year-old man who presented to our hospital with an infected wound on his leg. Discharges from the cracks of the granulation were collected and evaluated in our microbiology laboratory.
