Nadir Bir Patojen Comamonas Testosteronı: Olgu Sunumu Ve Literatürün Gözden Geçirilmesi

Gram negatif, hareketli, aerobik ve sporsuz bir basil olan Comamonas testosteroni tüm dünyada yaygın olarak bulunmaktadır. Düşük virulans potansiyeline sahip olan bu mikroorganizma nadiren insanlarda enfeksiyona neden olmaktadır. Burada 62 yaşında, sol hemiparezisi ve tip II diyabeti olan ve her iki koldan alınan kan kültürlerinde Comamonas testosteroni ürettiğimiz erkek olgu sunulmaktadır. İdentifikasyon çalışmaları Vitek 2 otomatize sistemi (bioMérioux, Fransa) ile ve bazı konvansiyonel testlerle yapıldı. Antibiyogram çalışmalarında ek olarak Kirby-Bauer disk difüzyon yöntemi kullanıldı. Mikroorganizma aztreonam ve kolistine dirençli, tetrasikline orta duyarlı ve piperasilin, piperasilin-tazobaktam, seftazidim, sefepim, imipenem, meropenem, amikasin, gentamisin, netilmisin, tobramisin, siprofloksasin, levofloksasin, tigesiklin ve trimetoprim-sulfametaksazole duyarlı bulundu. Mikroorganizma değişen antibiyotik direnç profili ile kan kültürlerinden izole edilebilecek nadir bir etken olarak akılda tutulmalıdır.

A Rare Pathogen Comamonas Testosteroni: Case Report And Review Of Literature

Comamonas testosteroni is a Gram negative, motile, aerobic and non-spored bacillus which is commonly found worldwide. This microorganism has low potential of virulence and rarely causes human infections. Here we report a 62 years old male patient having left hemiparesis and type II diabetes. Comamonas testosteroni was isolated from blood cultures taken from both arms. Vitek 2 automatized system (bioMérioux, Fransa) was used and some conventional tests were done for identification. For antibiotic susceptibility studies Kirby-Bauer disc diffusion method was used. Microorganism was found resistant to aztreonam and colistin, moderately susceptible to tetracycline and susceptible to piperacillin, piperacillin-tazobactam, ceftazidime, cefepime, imipenem, meropenem, amikacin, gentamicin, netilmicin, tobramycin, ciprofloxacin, levofloxacin, tigecycline and trimethoprim-sulfamethoxazole. It must be kept in mind that microorganism is a rarely isolated pathogen from blood cultures with its changing antibiotic resistance profile.
