Abstract

Neonatal sepsis is the most serious disease encountered in the neonatal Intensive Care Unit, and is associated with high morbidity and mortality rates. Here, we evaluated coagulase-negative Staphylococcus strains and the corresponding antibiotic susceptibility profiles in clinically suspected cases of neonatal sepsis. The objectives of the study were to determine the significance of coagulase-negative Staphylococcus strains isolated from cases of neonatal sepsis, another isolation site for coagulase-negative Staphylococcus other than blood culture and their susceptibility pattern. In a prospective study of newborns admitted to our neonatal Intensive Care Unit between January 20th, 2017, and January 20th, 2019, we analyzed all cases of sepsis with a positive blood culture, and available stool, central venous catheter, tracheobronchial, and nasopharyngeal fluid. Strains were identified using Matrix-Assisted-Laser Desorption Ionization Time of Flight Mass Spectrometry. Antimicrobial susceptibility patterns were recorded and analyzed. Of 157 premature newborns enrolled in the study, 28 (17.8%) had a coagulase-negative Staphyloccus-positive blood culture. Eighteen (64.2%) presented with early onset sepsis and 10 (35.8%) presented with late onset sepsis. Based on the gestational age at birth, there were 10 (35%) extremely preterm newborns, 12 (42.8%) very preterm newborns, and 6 (21.5%) moderately preterm newborns. The birth weight was extremely low in 13 (46.4%), very low in 9 (32.2%), low in 4 (14.2%), and normal 2 (7.2%). All coagulase-negative Staphylococcus isolates showed high levels of resistance to cefoxitin (100% of the strains), aminoglycosides (100%), fusidic acid and, ofloxacin (100%). The isolates were highly susceptible to pristinamycin (100% of the strains), vancomycin (100%) and trimethoprim-sulfamethoxazole (100%). Coagulase-negative Staphylococcus isolates constituted the most frequent cause of neonatal sepsis. The abundance of these strains may contribute to the emergence of multi-drug resistance.
