Rod-shaped bacteria transferring DNA. Computer artwork showing two typical rod-shaped bacteria transferring DNA (deoxyribonucleic acid) between themselves. DNA transferral between bacteria helps to build up resistance to antibiotics and other inhospitable environments. Typical rod-shaped bacteria (bacilli) are Escherichia coli and Salmonella bacteria, but there are many others. The bacteria shown here have flagella (hair-like structures), which enable them to move.
