Antibiotic Resistance of Airborne Viable Bacteria and Size Distribution in Neonatal Intensive Care Units

Abstract: Despite their significant impact on public health, antibiotic resistance and size distributions of airborne viable bacteria in indoor environments in neonatal intensive care units (NICU) remain understudied. Therefore, the objective of this study was to assess the antibiotic resistance of airborne viable bacteria for different sizes (0.65–7 µm) in private-style and public-style neonatal intensive care units (NICU). Airborne bacteria concentrations were assessed by a six-stage Andersen impactor, operating at 28… Show more

“…Regular monitoring of indoor environmental conditions is essential to assess the efficiency of environmental control practices [9,48,59,68] and to the detected presence of mycotoxins in HVAC filters [73]. The importance of controlling airborne particles in intensive care units is highlighted, due to the patient's compromised immune system [70,74,75]. The influence of the outdoor environment on indoor microbiological contamination is established [49,[76][77][78][79], as well as the importance of adequate indoor temperature and relative humidity control to reduce microbiological loads [17,19,68].…”

“…S. cohnii has long been considered a commensal organism of the skin, capable of effectively suppressing skin inflammation [24]. However, recent years have seen increasing reports of S. cohnii-induced infections, leading to the occurrence of various diseases in animals and humans, encompassing sepsis, brain abscess, and pneumonia [25][26][27][28]. Nonetheless, animal experimental studies remain scarce.…”

“…In our study, more than half of the isolates were MDR, as has been observed in other studies carried out in Brazil, Colombia, and Kuwait. Those studies reported MDR S. epidermidis on “high-touch” surfaces, in NICU environmental air, and in clinical samples (52.7%, 33.9%, and 61.8%, respectively) [ 28 , 29 , 30 ]. Our study revealed the presence of S. epidermidis MDR in much higher percentages (81%), 72.7% of inanimate surfaces, 68.8% of air, and 100% of clinical isolates, which alerts us to the need for urgent measures to minimize the risk of proliferation of these microorganisms in the NICU.…”
