Antimicobial susceptibility profiles of Gram positive cocci isolated from bacteremia in pediatric patients

Inections in pediatric ages arouse great concer both in family members and in the medical personnel who care for them. This is due to the serious prognosis of some of them in relation to survival and possible sequelae. The objective of ths research was to determine the profiles of antimicrobial susceptibility and multiresistance patterns were established in Gram positive cocci in blood culture from patients hospitalized at the Pepe Portilla Pediatric Teaching Hospital in Pinar del Rio from January to june 2021. An observational, descriptive and cross-sectional study was carried out with a universe consisting of 433 patients of pediatric ages, of which only 44 blood cultures (10, 16 %) were positive for Gram positive cocci. All variables were processed through a descriptive analysis where the number (nº) and percentage (%) were determined through the SPSS package. It was found that Staphylococcus epidermidis showed the highest percentage (77.3%) followed by Staphylococcus aureus (16, 9 %), Enterococcus spp (4, 5 %) and Streptococcus pneumoniae (2,3 %). Vancomycin, linezolid and teicoplanin showed the highest profiles of antimicrobial susceptibility to Gram positive cocci isolated in blood cultures in contrast to the generally decreased sensitivity to first generation penicillins and cephalosporins. 39.55 % o the Gram positive cocci isolated in bacteriemia showed some pattern of multidrugresistant microorganisms (MDR) represent 25 % of the isolates
