A case of total knee arthroplasty in which aeromonas hydrophila was ısolated in perioperative culture

Aeromonas hydrophila insanlarda çoğunlukla gastroenterit yapan ve sularda bulunan bir bakteridir. Son yıllarda Aeromonas türlerinin oküler, deri ve yumuşak doku, solunum sistemi ve üriner sistem infeksiyonu gibi çeşitli intestinal sistem dışı infeksiyonlara neden olduğu bildirilmektedir. İntestinal sistem dışı infeksiyonlar nadirdir. Bununla birlikte sunulan olguda bu bakterinin total diz protez ameliyatı sonrası protez infeksiyonu nedeni olabileceği gösterildi. Bu bildiride başka bir hastanede iki kez protez ameliyatı geçiren, hala ağrı ve pürülan akıntısı olan 73 yaşında bir bayan hasta sunuldu. Ameliyat sırasında alınan kemik ve yumuşak doku kültürlerinde A. hydrophila izole edilen olguda, bu bakterinin protez infeksiyonunun bilinen nadir etkenleri dışında protez infeksiyonu nedeni olabileceği gösterildi. Bu olguda protez infeksiyonlarında kesin tanı şansını artırmak için ameliyat sırasında birden fazla kemik ve yumuşak doku kültürünün alınması gerektiği vurgulandı.

Perioperatif kültüründe aeromonas hydrophila üreyen total diz artroplastisi yapılan bir olgu

Aeromonas hydrophila is a bacterium, which is found in ambient water and primarily causes gastroenteritis in humans. In recent years, Aeromonas strains have been reported to cause a variety of extraintesinal infections such as ocular, respiratory, urinary tract infections. The extraintestinal infections are usually rare. However, it is pointed that these bacteria can also be a cause of prosthesis infection after a total knee prosthesis operation in the represented case. In this report, a 73-year-old female patient was represented who had been operated twice because of prosthesis infection in another hospital and still has knee ache and purulent discharge at the incision site. In the perioperative bone and soft tissue cultures, A. hydrophila was isolated and it was shown that these bacteria could be the cause of prosthesis infection except known rare causes. In this case, it was emphasized that more than one perioperative bone and soft tissue cultures should be obtained to increase the chance for definitive diagnosis in prosthesis infection.
