Blood infection of Capnocytophaga canimorsus etiology following a dog bite: case report and review of the available literature
Abstract
We present the case of a 71-year-old man who developed sepsis caused by Capnocytophaga canimorsus as a result of being bitten by his own dog. Positive blood cultures were obtained, but due to difficulties in determining the bacterial species, the patient was treated empirically with ceftriaxone and levofloxacin. After using the recommended empirical therapy, the patient's condition improved. Capnocytophaga canimorsus is difficult to identify, among others, due to its long growth time and specific development conditions (capnophiles). These Gram-negative bacilli cause a number of diseases in humans, ranging from infections of the skin and subcutaneous tissue, through peritonitis, to sepsis. The portal of infection with these bacteria is most often a wound caused by an animal bite. Additional risk factors that increase the risk of developing a severe infection and even death include older age, concomitant chronic diseases, and immunosuppression.
Prezentujemy przypadek 71-letniego mężczyzny, u którego w wyniku pogryzienia przez własnego psa, rozwinęła się sepsa o etiologii Capnocytophaga canimorsus. Udało się uzyskać dodatnie posiewy krwi, ale z uwagi na trudności w ustaleniu gatunku bakterii, pacjent był leczony empirycznie ceftriaksonem z lewofloksacyną. Po zastosowaniu rekomendowanej terapii empirycznej stan pacjenta uległ poprawie. Capnocytophaga canimorsus sprawia trudności identyfikacyjne między innymi ze względu na długi czas wzrostu oraz specyficzne warunki rozwoju…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
