Fundamentos

Corynebacterium spp. es un género muy dispar que engloba especies poco conocidas y en el que sólo diphteriae, urealyticum y jeikeum son considerados patógenos indiscutibles. Otras especies como amycolatum están en la actualidad reivindicando su papel como agentes causales de patología infecciosa, en parte por su mejor conocimiento e identificación, y en parte por el aumento de pacientes inmunocomprometidos en los cuales suelen desarrollar todo su poder patógeno. Presentamos 3 casos de bacteriemia presumiblemente significativa por C. amycolatum.

M ÉTodos

Los aislamientos bacterianos a partir de hemocultivos se llevaron a cabo utilizando un sistema vital. La identificación se realizó mediante tinción de Gram, morfología de la colonia, los resultados de numerosas pruebas bioquímicas (incluido el sistema Api Coryne), el comportamiento de aislados frente al agente vibriostático O\129 y el patrón de sensibilidad antibiótica obtenido mediante E-test.

Resultados

Los tres aislamientos de C. amycolatum pertenecían a pacientes hospitalizados largo tiempo, multi-instrumentados y con patología grave de base. Los tres tuvieron otros aislamientos concomitantes por C. amycolatum en otra localización: esputo, escara y catéter, respectivamente, lo cual podría explicar la procedencia de la bacteriemia. La morfología de la colonia, los patrones de sensibilidad antibiótica, su resistencia frente al agente vibriostático O\129 y las pruebas bioquímicas utilizadas fueron semejantes en los tres casos y a los descritos previamente en la literatura.

Conclusiones

C.amycolatum debe ser tenido en cuenta como agente responsable de patología grave y significativa en este tipo de pacientes. Además posee ciertas características específicas que facilitan su sospecha en el trabajo habitual del laboratorio de microbiología.

Background

Corynebacterium sp. is an extremely varied genus which includes little known species and of which only Corynebacterium diphteriae, Corynebacterium urealyticum and Corynebacterium jeikeium are considered indisputable pathogens. Other species, such as C. amycolatum are at present being reconsidered as causative agents in infectious pathologies, partly on account of our greater aquaintance and improved identification techniques for these microorganisms and partly on account of the growing number of immunocompromised patients in whom all their pathogenic capacity is usually able to develope. We present 3 cases of significant bacteremia by C. amycolatum.

Methods

Bacterial isoliations from blood culture were obtained using the Vital Systems. Identification was performed by means of Gran stain, colony morphology, the results of numerous biochemical tests (including the Api Coryne systems), the behaviour of the strains against the vibriostatic agent O/129 and the antibiotic susceptibility pattern obtained with the E-test.

Results

The three isolates of C. amycolatum were obtained from patients after a lenghtly hospitalization, multi-instrumentation and who had severe underlying disease. All three presented with concomitant isolates of C. amycolatum from other sites: sputum, wound and catheter respectively, which could explain the origin of the bacteremia. Colony morphology, antibiotic susceptibility patterns, resistance to the vibriostatic agent O/129 and the results of the biochemical test carried out were similar to those previously describe in the literature.

Conclusions

C.amycolatum should be born in mind as a agent responsable for significant and severe pathology in this type of patient. In addition, it as certain specific characteristics which assits in its identification in the normal microbiology laboratory.
