“…In fact, the airborne Gram-positive cocci (Staphylococcus and Micrococcus) were also the most detected bacterial genera in a sensitive ward of an academic pediatric hospital in Iran [84], in hospitals in India [85], in a hospital ward in India [67], in five educational Hospital wards air in Iran [86], in General Hospitals of Korea [87], in a regional Danish hospital [88] and in tertiary university hospital in NE Greece [89]. In our study, higher gram-positive cocci isolates were found in the treatment rooms and vaccination rooms of both PHCC, smaller spaces where they perform nursing treatments, shared between workers and patients, exposing them to both.…”

This study aims to assess the airborne bioburden of rural and urban Portuguese Primary Health Care Centers (PHCC) using active and passive sampling methods and identify the potential differences in airborne microbiota between both environments. The highest total aerobic mesophilic bacterial load in indoor air were found in the Vaccination Room (448 CFU.m−3) in the Rural PHCC and in the Waiting Room (420 CFU.m−3) for Urban PHCC. The total coliforms contamination level in indoor air was detected only in the Cleaning Supplies Room (4 CFU.m−3) in the Urban PHCC. The most frequent bacteria genera identified was Micrococcus (21% Rural PHCC; 31% Urban PHCC). The surface samples showed a highest total aerobic mesophilic bacterial contamination in the Treatment Room (86 × 103 CFU.m−2) from the Rural PHCC and in the Front Office (200 × 103 CFU.m−2) from the Urban PHCC. The electrostatic dust cloth (EDC) samples showed a highest bacterial load in the Urban PHCC. Total aerobic mesophilic bacterial load in settled dust and in the Heating, Ventilating and Air Conditioning (HVAC) filter samples in the Urban PHCC (8 CFU.g−1 and 6 × 103 CFU.m−2) presented higher values compared with the Rural PHCC (1 CFU.g−1 and 2.5 × 103 CFU.m−2). Urban PHCC presented higher bacterial airborne contamination compared with the Rural PHCC for the majority of sampling sites, and when compared with the indoor air quality (IAQ) Portuguese legislation it was the Rural PHCC in two sampling places who did not comply with the established criteria.

Objectives To investigate the clinical and drug resistance characteristics of Providencia stuartii infections in the Huainan region of Anhui and provide a reference for the clinical selection of antimicrobial agents. Methods This single-center retrospective analysis included 76 patients with P. stuartii infection in Huainan during the period from October 2018 to March 2020. The hospital department in which the patients were treated and the drug susceptibility characteristics of the P. stuartii isolates were recorded. Results Among the 76 patients, the lung was the most common site of infection, and intensive care unit was the main hospital department. Extended spectrum beta-lactamase screening revealed expression by all 76 isolates of P. stuartii. Of the 76 isolates, 92.1% exhibited multiple drug resistance or extensive drug resistance. P. stuartii isolates were sensitive to cefepime and imipenem, but not to other beta-lactam antibiotics. Twenty isolates were resistant to all 21 types of antibiotics. Of the 20 patients infected with extensively drug-resistant isolates, nine (45%) died. Conclusions Drug resistance is increasing in P. stuartii. The antimicrobial agent imipenem may be effective for treatment of P. stuartii infections. Fluoroquinolones, aminoglycosides, and fourth-generation cephalosporins are suitable options for antibiotic therapy.

Staphylococcus aureus is one of the pathogenic bacteria that cause nosocomial infections in hospitals. The use of essential oil-based antibacterials for hospital wards was developed to prevent nosocomial infections. Laja gowah oil is an essential oil isolated from the Alpinia malaccensis plant, which belongs to the Zingiberaceae plant group. The purpose of this study was to determine the antibacterial activity of laja gowah oil in reducing the number of S. aureus colonies in hospital inpatient rooms through the air diffusion method. The compound content in laja gowah oil was analyzed with GC-MS. The study of antibacterial activity using the total plant counts continued with the colony count test, Gram staining, catalase test, and coagulase test. Laja gowah oil contains methyl cinnamate and 1,8-cineole. The installation time of the diffuser containing laja gowah oil affects the number of colonies of S. aureus bacteria in hospital wards. The antibacterial activity of laja gowah oil was influenced by the synergistic effect of methyl cinnamate and 1,8-cineole compounds.
