RESUMO
PURPOSE: We report a case of infectious keratitis caused by Shewanella putrefaciens in a patient after fishing. CASE SUMMARY: A 75-year-old male with no underlying disease other than hypertension was admitted to our hospital because of decreased visual acuity and congestion in his left eye for 2 weeks. At the first ophthalmic examination, the best-corrected visual acuity (BCVA) of the left eye was counting fingers. Slit lamp examination showed stromal infiltrates with 2.0 × 2.0 mm corneal epithelial defects, endothelial inflammatory plaques and 1 mm height hypopyon with severe inflammation in the anterior chamber. Bacterial culture tests were performed by corneal scraping, which were positive for Shewanella putrefaciens, followed by treatment with moxifloxacin and ceftazidime topical antibiotics. After 2 months of treatment, the BCVA of the left eye improved to 0.4 and the corneal lesion clinically improved with residual mild stromal opacity. CONCLUSIONS: Shewanella putrefaciens should be considered as a causal pathogen of infectious keratitis in patients after fishing. We report a case of infectious keratitis caused by Shewanella putrefaciens, which has never previously been reported in the Republic of Korea.

Shewanella putrefaciens es un bacilo gramnegativo, no fermentador, oxidasa positivo, productor de sulfato de hidrógeno, que de manera inusual causa cuadros infecciosos en humanos. Este germen oportunista produce infecciones en pacientes inmunosuprimidos y/o con antecedente de exposición a comida o agua de mar contaminados con el germen. A continuación presentamos un reporte de caso de un paciente con una infección del páncreas por este germen.
Shewanella putrefaciens is a rare Gram-negative bacillus, non-fermenting, oxidasepositive, and a hydrogen sulfide producer, which infrequently causes human infections. This opportunist germ causes infections in immunosuppressed people and in those with a history of contact with seawater or food contaminated with the microbe. We present a case of a patient with a pancreatic infection caused by this microbe.

Shewanella putrefaciens rarely causes infection in humans. In the last few decades a growing number of cases have been described. The following report outlines the case of a 40-year- old immunocompetent white man with S. putrefaciens infective endocarditis. This is the first known case of infective endocarditis due to an apparently monomicrobial S. putrefaciens infection, and the second known case of S. putrefaciens-related infective endocarditis worldwide.

One hundred and thirty three non fermenting gram negative bacilli isolated out of 625 different clinical specimens were identified and characterised. Samples were exudate from chronic suppractive otits media (341), diabetic foot (117) wound (116) and blood (51). Of these isolates Pseudomonas aeruginosa 105(78.94%) predominated followed by Acinetobacter sp 8 [6.1%], Pseudomonas putrifaciens 6(4.5%), Flavobacterium sp 6(4.5%), Xanthomonas maltophilia 5(3.75%), Alkaligenes sp 3 (2.25). 31 (23.30%) were resistant to commonly used antibiotics. Amikacin 85 (63.90%) was found to be more effective than fluoroquinolones (27.8-48.12%).
