Technological advances often lead to better science, but every now and then opting for the lowest tech levels possible can achieve the best outcome. <\/p>\n
This was demonstrated spectacularly this month when a team of British microbiologists found that the best tool for determining the size of nasty bug population wasn't a laser or a chromatograph or a sophisticated scanner, but a sock. <\/p>\n
The scientists, led by Natalia Jones from the University of East Anglia, wanted to assess the population density of a gastrointestinal bacteria species called Campylobacter in a couple of rural areas. <\/p>\n
After much thought, they realised that the best way to do this was to enlist a cohort of volunteers and ask them to walk along country lanes while wearing a sock over one boot. Participants were asked to repeat the process over a 16 month period. <\/p>\n
At the end of each walk, the volunteers were instructed to mail the sock to the university, an act that doubtless raised a few eyebrows at the local post office. <\/p>\n
Once received, Jones and colleagues grew some of the gungy bits in Petri dishes, and subjected others to a process known as polymerase chain reaction in order to reveal the microbial population picked up along the way. <\/p>\n
The results showed that the bacteria were most common in areas associated with livestock farming, and reached peak density in winter. <\/p>\n
The team hopes the data will help to explain the ways in which Campylobacter infects people. It's a common cause of food poisoning, but that alone doesn't account for all the cases. <\/p>\n
The scientists' report was published in the journal Applied and Environmental Microbiology. It is unknown whether laboratory equipment stores will now start stocking footwear. <\/p>\n
