Biometric devices (BDs) are nowadays common in use for a variety of purposes. The study conducted to
assess the bacterial load on fingerprint scanners (FPS) of BDs revealed the presence of 0.26 × 103
to 3.83 ×
103
colony-forming units of bacteria per cm2 of FPS. A total of 58 isolates of bacteria belonging to 23 species
of which 42 isolates had multiple drug-resistant were identified on FPS of 17 BDs. Types of bacteria and
bacterial load on finger print scanners of high use BDs was significantly (p, ≤ 0.01) higher than on FPS of
low use BDs. Gram negative bacteria belonging to Aeromonas bestiarum 1, A. media 2, Enterobacter
agglomerans 10, Erwinia mallotivora 2, Escherichia coli 1, Klebsiella pneumoniae ssp. pneumoniae 1, and
Shewanella putrifaciens 1, were detected from nine finger print scanners. The 40 gram-positive bacteria
were detected on all finger print scanners’ samples and belonged to five genera. Both of the Bacillus
thurigiensis isolates were from finger print scanners of BDs installed in the same building. Enterococcus
faecium and Enterococcus faecalis strains were detected on three samples each. All 22 isolates of
staphylococci were resistant to methicillin and oxacillin and 20 had multiple drug-resistance. Vancomycin
resistant Enterococcus, E. faecalis, was detected in one sample and vancomycin-resistant Staphylococcus
aureus were detected from two samples. Both of the linezolid-resistant isolates (Staphylococcus
chromogenes and Streptococcus milleri) were detected from finger print scanners of two of the high use
BDs. Of the 58 isolates, 10 from seven samples (all from high use or medium use BDs) were resistant to
one or more carbapenem drugs and two isolates of Enterobacter agglomerans possessed metallo-βlactamase activity. The study indicated that BDs may be harbouring potentially dangerous superbugs and
suggest the use of touch-less BDs for commonplace uses.
