Scientists bring to light microbes that grew on mobile phones

Pune:

Scientists in Pune have discovered new species of microbes which flourished on mobile handsets.

How dirty are these pervasive mobile phones?

Mobile phones have been termed more dirtier than toilet seats, according to the reports from Western nations. Some smartphones even known to harbour drug-resistant bacteria which are deadly in nature.

Two bacteria and fungus, never before reported in scientific literature, were identified by this laboratory funded by the Department of Biotechnology.

Earlier a study done in 2015 by William DePaolo, an assistant professor in the Molecular Microbiology and Immunology Department at the University of Southern California, found that toilet seats usually contained three different types of bacteria but mobile phones on an average housed some 10-12 different types of fungi and bacteria.

Mobile phones since they are carried in almost all human environments from the kitchen to the public transport harbour a larger diversity of micro-organisms. These microbes grow well on the sweat and grime left on the phones as humans carry them around.

In Pune, Yogesh S Shouche and his team from the Microbial Culture Collection group of the NCCS collected samples from 27 mobile phone screens and they were able to isolate 515 different bacterial types and 28 different fungi.

These microbes are friendly to humans and usually thrive on our bodies, says Praveen Rahi, a co-investigator for the work.

The team used sterilised cotton swabs and sterile saline solution to wipe from the surface these microbes which were then grown using standardised culture media at 30 degrees centigrade.

But what surprised this six-member team was that they encountered three new species of organisms—two bacteria they have named Lysinbacillus telephonicus and Microbacterium telephonicum and a new species of fungi that they named Pyrenochaeta telephoni.
