Topical lotions utilized in outpatient rehabilitation clinics as a potential source of bacterial contamination

Abstract

Soft tissue mobilization and massage requiring lotions or creams are commonly used interventions in outpatient rehabilitation clinics. For at least 50 years hand creams used in healthcare settings have been found to be contaminated by bacteria. The purpose of this study was to determine the current state of bacterial contamination of lotions used in clinics and to determine the efficacy of lotion preservatives to kill bacteria. Unopened containers of lotions were studied, along with 81 lotion containers used in 22 outpatient clinics in southeast Tennessee and northwest Georgia. Three sites on each container were sampled using sterile swabs. At a microbiology lab, bacterial growth media was inoculated and incubated. Of the 81 containers sampled, 16 supported bacterial growth (19.8%). Container threads displayed the highest contamination compared with other container locations (p < 0.01). No bacteria were found in unopened lotion containers, although when challenged with live bacterial cultures lotion preservatives did not kill bacteria tested. Enrichment cultures using lotions studied here supported the growth of several bacterial species. These findings suggest the need for standardized protocols to help reduce potential healthcare-associated infections due to use of lotions. Improved efficacy of preservatives added to lotions should be a priority.

Modèles alternatifs dans la pratique de la rééducation à l’ère de la pandémie de Covid-19

“…C'est le cas en particulier des masques N95 qui nécessitent plus d'efforts pour respirer lorsqu'ils sont portés [8]. Bien que des infections spécifi ques aux milieux de réadaptation soient rares, des données ont montré la persistance des agents bactériens dans les équipements de réadaptation tels que les appareils d'électrothérapie et d'ultrasons [11,12], les équipements de kinésithérapie [13,14], d'ergothérapie [15] ou de balnéothérapie [16] qui peuvent être source de contamination pour le personnel et/ou les patients. Pour prévenir ce risque infectieux, les besoins spécifi ques de réadaptation, tels que les contacts humains et physiques ou les interactions sociales (patient, aidant, famille, soignants) sont devenu irréalisables [17].…”

“…This antibiotic-resistant bacteria has been reported to contaminate ultrasound gel in healthcare facilities (7) . Based on reports, 80% of S. aureus can survive on ultrasound gel for 1 hour, has the potential for cross-contamination between patients and allows patient infection in hospitals (health care-associated infection) (8,9) .…”

Phylogenetic investigation of Gammaproteobacteria proteins involved in exogenous long-chain fatty acid acquisition and assimilation

“…Gammaproteobacteria contains many pathogens, such as several Vibrio species ( cholerae , parahaemolyticus , vulnificus , and alginolyticus) , Allivibrio ficheri , Klebsiella pneumoniae , and Pseudomonas aeruginosa , and the model bacterial organism Escherichia coli [ [3] , [4] , [5] , [6] , [7] , [8] ]. Many members of this class, including all the aforementioned species, are able to incorporate exogenous fatty acids, including polyunsaturated fatty acids (PUFAs), into the phospholipids of their membranes [ [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] ]. Such assimilation results in phospholipid structural modifications, causing increased membrane permeability to hydrophobic compounds and altered resistance to certain antibiotics.…”
