However, it has a comparable infectious capacity since it can be involved in severe diseases like bacteremia or meningitis. Its habitat is variable, usually found in humid tropical climates (as is the case in Colombia), soil, water, or animal reservoirs. It is still an unknown germ for most health personnel, as there are not many reported cases, and information about its microbiological and epidemiological characteristics is still scarce, making its identification and treatment difficult.  Clinical case: We describe the case of A. johnsonii infection of the central nervous system in a 15-year-old female, as well as the diagnostic method used, the course of the disease, medical management, and clinical outcome.  Conclusions: It is of utmost importance to report this type of microorganisms to facilitate early diagnosis and appropriate treatment. More scientific publications of this type are needed to broaden the knowledge about these microorganisms.]]></p></abstract>

Sin embargo, posee una capacidad infecciosa equiparable, ya que se puede ver involucrado en patologías graves, como bacteriemia o meningitis. Su hábitat es variable y suele encontrarse en climas tropicales húmedos (como es el caso de Colombia), suelos, aguas o reservorios animales. Actualmente sigue siendo un patógeno desconocido por gran parte del personal de salud, pues no existen muchos casos reportados, y la información acerca de sus características microbiológicas y epidemiológicas aún es escasa, lo que dificulta su identificación y tratamiento.  Caso clínico: Se describe una infección del sistema nervioso central por A. johnsonii en una paciente de sexo femenino de 15 años, así como el método diagnóstico utilizado, el curso de la enfermedad, el manejo médico y el desenlace clínico.  Conclusiones: Es de suma importancia dar a conocer la existencia de estos microorganismos para facilitar el diagnóstico temprano y el tratamiento apropiado. Se requieren más publicaciones científicas de este tipo para ampliar el conocimiento acerca de estos microorganismos.]]></p></abstract>
