Introduction

Streptococcus gender taxonomy has changed, due to the use of molecular biology tools that allows the identification of new pathogenic species like Streptococcus pluranimalium, which in Mexico has only been reported in adults.

Objetive

To report the first three pediatric cases of Streptococcus pluranimalium bacteremia.

Clinical Cases

Three clinical cases of female patients of pediatric age, the first of nine months with ventilator-associated pneumonia, were treated with vancomycin. The second of 23 months with sub-mandibular abscess treated with amoxicillin / sulbactam and the third of 11 years with endocarditis and bacteremia by Pseudomonas aeruginosa, received vancomycin, meropenem and gentamicin, died of heart failure. All patients had bacteremia due to Streptococcus pluranimalium.

Discussion

Streptococcus pluranimalium has not been reported previously in children. It could be pathogen in different and severe animal and human infectious process.
