La infección de la vesícula biliar por bacterias del género Actinomyces es extremadamente rara, habiéndose descrito hasta la fecha 25 casos en la literatura. Presentamos el caso de un hombre de 68 años que ingresó por un cuadro de fiebre de corta evolución sin focalidad infecciosa aparente. Las pruebas complementarias revelaron la existencia de colecistitis aguda perforada junto con bacteriemia por A. naeslundii. El paciente realizó tratamiento antibiótico con amoxicilina-clavulanato durante 3 semanas, sensiblemente inferior a las pautas habituales. Posteriormente se sometió a una colecistectomía electiva. El estudio histopatológico de la pieza quirúrgica confirmó la resolución completa de la infección.

Backgrounds Actinomyces species are gram-positive, obligate anaerobic rods and are rare causes of cholecystitis. Because Actinomyces species are anaerobic bacteria, it is difficult for Actinomyces to survive in bile apart from A. naeslundii. We experienced a case of recurrent acute cholecystitis caused by A. odontolyticus. Case presentation A patient had been diagnosed with acute cholecystitis and treated one month before and after that, admitted to our hospital because of recurrent cholecystitis. Gram stain of the bile revealed gram-positive rods and gram-positive cocci. We found A. odontolyticus and MRSA in bile culture and MRSA in blood culture. We administered piperacillin-tazobactam and then changed it to ampicillin-sulbactam and vancomycin. The patient underwent laparoscopic cholecystectomy and was discharged safely. Conclusions To our knowledge, this is the first case of cholecystitis caused by A. odontolyticus. Cholecystitis caused by Actinomyces species is rare. In addition, we may overlook it with the low positivity of bile cultures of Actinomyces. Whenever the cholecystitis recurs without any obstruction of the biliary tract, we should search for the gram-positive rods hidden in the bile, such as A. odontolyticus, as the causative organism, even if the bile culture is negative.
