    Abstract:
    Clostridium tertium is a bacterium of the Clostridiaceae family which can be found colonizing the gastrointestinal tract. Unlike other members of its family, it does not produce exotoxins. It was described for the first time in 1917 and in 1963 it was established as a pathogen in humans. Since then, cases have been reported mainly in immunosuppressed hosts, predominantly with primary focus at the abdominal level. The case of a 48-year-old man with a history of cirrhosis and hepatitis C virus infection is described. He presented an obstructed umbilical hernia that required intestinal resection and anastomosis, with positive blood and abdominal fluid cultures for Clostridium tertium. This case is of clinical importance due to the low prevalence of this germ, the possibility of resistance to usual antibiotic regimens and its sub diagnostic given the morphological and growth similarities with Bacillus or Lactobacillus. Clostridium tertium es una bacteria de la familia Clostridiaceae que se puede encontrar colonizando el tracto gastrointestinal. A diferencia de otros miembros de su familia, no produce exotoxinas. Fue descripto por primera vez en 1917 y en el año 1963 se pudo establecer como patógeno en humanos. Desde entonces, se han reportado casos principalmente en huéspedes inmunosuprimidos, prevalentemente con foco primario abdominal. Se describe el caso de un hombre de 48 años de edad con antecedentes de cirrosis e infección por virus de la hepatitis C, presentó una hernia umbilical atascada que requirió resección y anastomosis intestinal, con cultivos de líquido abdominal y hemocultivos positivos para Clostridium tertium. Este caso es de importancia clínica por la baja prevalencia de este germen, la posibilidad de resistencia a los esquemas antibióticos usuales y de subdiagnóstico del microorganismo dada su similitud morfológica y de crecimiento con Bacillus o Lactobacillus.
