Abstract: Serratia marcescens has emerged as an important opportunistic pathogen responsible for nosocomial and severe infections. Here, we determined phenotypic and molecular characteristics of 54 S. marcescens isolates obtained from patient samples from intensive-care-unit (ICU) and neonatal intensive-care-unit (NIUC) of a Brazilian tertiary hospital. All isolates were resistant to beta-lactam group antibiotics, and 92.6% (50/54) were not susceptible to tigecycline. Furthermore, 96.3% showed intrinsic resistance to po… Show more

“…They were spread among all (100%) of the herbal remedies. This compares substantially to some previous studies on herbal remedies where total coliforms were recovered from 77.8% of the herbal medicines samples [11]; also coliforms were recovered from 81.7% of traditional liquid herbal medicinal products in Kenya [12]. In four (33.3%) of the herbal remedies, the total coliform counts exceeded the WHO maximum limit of 10 3 /ml of herbal remedies for enterobacteriae [13].…”

“…The persistence of Escherichia coli and other faecal indicator bacteria particularly coliforms in the environment has been attributed to be dependent on a number of factors including the physicochemical status of the environment such as changes in temperature, pH, humidity, salinity the presence of other bacteria, viruses and predators and the metabolic capacities of the bacteria [28]. Escherichia coli is a commonly reported contaminant in herbal products in varying prevalences such as 4.5% [12] 6.7% [15] and 25.8% [11] while in this study like in a number of others E coli were not recovered from herbal remedies [29,16].…”

“…Frequent and sensitive microbiological screening to quickly detect positive patients and monitor potentially ongoing transmission was essential. Repeated screening has also been described in other Sm clusters and is an important tool in outbreak control [ 2 ], [ 7 ]. To increase sensitivity, we made use of the intrinsic resistance of Sm against colistin.…”

“…The last S. marcescens cellulolytic bacterium was isolated from the termite gut in Rayong Province. It is a human opportunistic pathogen that naturally resides in the soil and water, producing a red pigment at room temperature (Ferreira et al 2020). It was also reported as a cellulolytic bacterium isolated from a higher termite O. formosanus (Kavitha et al 2014).…”
