A 59-year-old man with systemic lupus erythematosus (SLE) on hemodialysis presented with cellulitis of the left upper limb after being bitten by his cat and was admitted to our hospital. Blood cultures were obtained, and empiric treatment with ampicillin/sulbactam was initiated. The patient developed a non-severe drug eruption on the 3rd hospital day, prompting a switch to ceftriaxone. Thin spindle-shaped Gram-negative bacilli were isolated from the blood cultures 127 h (5 days and 7 h) after obtained blood sample, and the patient completed a 2-weeks course of ceftriaxone with complete recovery. The isolate was identified as <em>Capnocytophaga cynodegmi</em> by MALDI-TOF MS and 16S rRNA gene sequencing. This case highlights the importance of considering <em>C. cynodegmi</em> in cat bite-associated infections.

In this case, a rectal swab culture and stool examination were requested for investigation due to diarrhea. Bacteriological laboratory tests revealed an intestinal infection with <em>Aeromonas</em> species. Confirmation was therefore carried out using the automated BD Phoenix system and biochemical reactions. The results showed <em>Aeromonas veronii</em> biovar <em>sobria</em>. Fortunately, in our cases, the intestinal infection was self-limiting and no antibiotics were given. This case highlights a rare occurrence of <em>Aeromonas</em> intestinal infection and demonstrates the risk of river and freshwater fish in transmitting <em>Aeromonas</em> to humans, especially in infants and child, which can be dangerous for this age group. It highlights the potential health risks associated with drinking water from natural sources, especially in rural areas or in underserved areas where the quality of the water may be compromised. To understand the prevalence of <em>Aeromonas</em> infections in similar settings and develop targeted prevention strategies, we recommend further epidemiological studies and healthcare providers should be vigilant and consider <em>Aeromonas</em> as a potential pathogen in patients with gastrointestinal symptoms, especially after exposure to contaminated water.</div></div>","PeriodicalId":47045,"journal":{"name":"IDCases","volume":"40 ","pages":"Article e02245"},"PeriodicalIF":1.1,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143911575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
