3.1.3. Resistance along the Organisms Studied

The AMRS were based on 18 organisms (genus), with species or serovars appearing at least once (Figure 1). The organisms' appearance, in descending order, were: *Escherichia coli*, *Salmonella*, *Staphylococcus*, *Pseudomonas*, *Klebsiella, Bacillus*, *Enterococcus*, *Proteus*, *Vibrio*, *Listeria*, *streptococcus*, *Citrobacter*, *Aerobacter*, *Clostridium*, *Enterobacter*, *Micrococcus*, and *Serratia* (Figure 1). The distribution of the organisms studied yearly at geopolitical zones demonstrated some organisms were studied more in particular regions or geopolitical zones of Nigeria (Figure 2).
