Isolation frequency of Candida present on the surfaces of mobile phones and handsx

The main aim of our study was to verify the effectiveness of simple disinfection using wet wipes for reduction of microbial contamination of mobile phones and computer keyboards. Bacteriological swabs were taken before and after disinfection with disinfectant wipes with active ingredients chlorhexidine digluconate and triclosan. The incidence and type of microorganisms isolated before and after disinfection was evaluated; the difference was expressed as percentage of contamination reduction. Our results confirmed the high degree of surface contamination with bacteria, some of which are opportunistic pathogens for humans. Before the process of disinfection, on both surfaces, mobile phones, and computer keyboards, the common skin commensal bacteria like coagulase-negative staphylococci were diagnosed most frequently. On the keyboards, species of the genus Bacillus and representatives of the family Enterobacteriaceae were abundant. The potentially pathogenic species were represented by Staphylococcus aureus. Cultivation of swabs performed 5 min after disinfection and subsequent calculation of the reduction of contamination have shown that simple wiping with antibacterial wet wipe led to a significant reduction of microbial contamination of surfaces, with effect ranging from 36.8 to 100%.

“…Nevertheless, C. glabrata strains have also been isolated from non-human sources, including from fermenting coffee beans (de Melo Pereira et al 2014 ), and, most commonly, from droppings or cloaca swabs of several bird species (Cafarchia et al 2008 ; Francesca et al 2014 ; Al-Yasiri et al 2016 ). Furthermore, C. glabrata can also be commonly found on the surface of hands or mobile phones of clinical workers (Kordecka et al 2016 ).

Genomes shed light on the secret life of Candida glabrata: not so asexual, not so commensal

Candida glabrata is an opportunistic yeast pathogen, whose incidence has increased over the last decades. Despite its genus name, this species is actually more closely related to the budding yeast Saccharomyces cerevisiae than to other Candida pathogens, such as Candida albicans. Hence, C. glabrata and C. albicans must have acquired the ability to infect humans independently, which is reflected in the use of different mechanism for virulence, and survival in the host. Yet, research on C. glabrata suffers from assumptions carried over from the more studied C. albicans. Regarding the adaptation of C. glabrata to the human host, the prejudice was that, just as C. albicans, C. glabrata is a natural human commensal that turns deadly when immune defenses weaken. It was also considered asexual, as no one has observed mating, diploids, or spores, despite great efforts. However, the recent analysis of whole genomes from globally distributed C. glabrata isolates have shaken these assumptions. C. glabrata seems to be only secondarily associated to humans, as indicated by a lack of co-evolution with its host, and genomic footprints of recombination shows compelling evidence that this yeast is able to have sex. Here, we discuss the implications of this and other recent findings and highlight the new questions opened by this change in paradigm.

Con el objetivo de identificar la presencia de microorganismos en los teléfonos móviles del personal de la unidad de cuidados intensivos (UCI) de un hospital en España se realizó un estudio transversal descriptivo entre los profesionales sanitarios y no sanitarios que tuvieran teléfonos móviles durante su jornada laboral. La recogida de muestras se llevó a cabo mediante hisopo y siembra en placa de cultivo con análisis e identificación de los microorganismos. Se analizaron 111 teléfonos móviles, de los cuales 56 estaban contaminados siendo 41,5% y 41,1% para los que pertenecían a las enfermeras y los médicos respectivamente y 60,6% para la encontrada en los auxiliares de enfermería, destaca el crecimiento de Pseudomonas aeruginosa (12,5%), Staphylococus aureus meticilin-resistente (10,9%), y Stenotrophomonas maltophila (4,7%). En conclusión, los teléfonos móviles presentaron presencia de microorganismos de relevancia clínica. La presencia de estas bacterias y hongos deben alertarnos sobre la posibilidad de que sirvan de reservorio para la transmisión al paciente crítico.
