First, two curves in the graph are observed, The logarithm of colony forming units (cfu) per lung lobe, for a wild strain (black) and a mutant strain (red). The bars show the variation from the average of log cfu.

Second, both type of bacteria strain grow to a maximum value close to 6 (log cfu), then drop down. Differences in CFU reduction was observed between the two types of strains.

In the first day, the mutant strain shows to be more aggressive than the wild-type bacteria. On the third day, the variation from the mutant bacteria is wider while the wild strain has more constant values.

The bars inspire me more range than SD, the variation at the third day is broader and asymmetric so I would think more in maximum and minimum values.

It could be better if the x axis are separated according to the days that take place, so the differences in the grow and reduction of CFU are more dramatic

wow.

Thanks Arturo. Your response very helpful
