Serotype

A serotype is a distinct variation within a species e.g. bacteria or virus, which can be distinguished in their antigens[1].

The serotype allows organisms to be classified more specifically than just by species, which can be useful in epidemiology[2].

Salmonella

Salmonella can be separated into many serotypes based on the O antigen and the H antigen[3].

Some serotypes of salmonella can cause more serious illnesses than others, meaning different minorities can be more susceptible to different serotypes[4].

Pneumococcal

When studied the distribution of specific serotypes were found to be linked to age and co-morbidity, with pneumonia rates increasing with both, however the specific serotypes found in the higher disease rates were the less invasive serotypes of pneumococcal[5].
