Resistance phenotypes of Gram positive cocci in pediatric blood cultures

Infections in pediatric ages constituye one of the biggest challenges today due to bacterial etiology related to high multidrug resistance. This research aimed to determine the resistance phenotypes in Gram positive cocci isolated in blood cultures 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 %). Resistance to penicillins, macrolides and clindamycin represent the largest percentage of phenotypes resistant to Gram positive cocci isolated in blood cultures of patients hospitalized in closed hospitalization services
