Other GNB such as Morganella morganii, Citrobacter freundii, Providencia stuartii
, Enterobacter cloacae, Stenotrophomonas maltophilia, and unidentified GNB revealed the highest resistance rates for cephalosporins (80% to 95%) and ciprofloxacin (72.2%).
The twenty strains of Gram-negative bacteria tested in this study were MDR isolates (laboratory collection) and reference strains (American Type Culture Collection) of Escherichia coli (ATCC8739, AG100A, AG100ATet, AG102, MC4100, and W3110), Enterobacter aerogenes (ATCC13048, CM64, EA27, EA289, and EA294), Klebsiella pneumoniae (ATCC11296, KP55, KP63, and K24), Pseudomonas aeruginosa (PA01 and PA124), and Providencia stuartii
(NEA16, PS2636, and PS299645).

(5), Providencia rettgeri (2), Providencia alcalifaciens/rustigianii (1), Shigella sp.
In 2011, the first reported identification of the blaNDM-1 gene was identified in Providencia stuartii
isolates recovered from an Afghan national burn patient treated at a US/coalition combat support hospital in Bagram, Afghanistan.
The studied bacteria strains included reference (from American Type Culture Collection) and clinical (Laboratory collection) strains of Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, Providencia stuartii
, and Pseudomonas aeruginosa.
His urine cultures had been positive for Escherichia coli, Proteus mirabilis, vancomycin-resistant Enterococcus faecalis, Pseudomonas aeruginosa, Providencia stuartii
, and on one occasion, an unidentifiable Gram-negative rod, which was later identified as Ignatzschineria indica.
coli E07-10537,9 and a blaDHA-1 negative Providencia stuartii
Here, the original urine specimen yielded Providencia stuartii
. The pathogenesis begins with the metabolism of tryptophan to indole, which is absorbed and detoxified to indoxyl sulfate (liver), and finally excreted by bacteria with sulfatase and/or phosphatase that metabolize indoxyl to indirubin (red) and indigo (blue) (3).
Bacteria implicated in the causation of PUBS include Providencia stuartii
, Providencia rettgeri, Klebsiella pneumoniae, Proteus species, Escherichia coli, Enterococcus species, Morganella morganii, and Pseudomonas aeruginosa.
Blood cultures on admission revealed several microbes: Enterococcus faecalis, Enterobacter cloacae, Providencia stuartii
, Corynebacterium spp., and a gram-negative bacillus resembling Pseudomonas.
Our data showed that Providencia stuartii
exhibited a resistance rate of 33.3% to amikacin and isepamicin.
