Salmonella Gallinarum biovar Gallinarum

Background information: Salmonella enterica subsp. enterica serovar Gallinarum (antigenic formula 1,9,12:–:–) is a serovar of the O:9 (D₁) serogroup. This serovar has two biovars: Gallinarum, and Pullorum. Biovar Gallinarum has been found to show host specificity for aquatic birds, and poultry and can cause fowl typhoid (acute or chronic septicemia) in birds of any age, often spreading through adult flocks. Fowl typhoid can spread through ingestion, such as contaminated food, water, or cannibalism, as well as through the respiratory system.

Other than being derived from animal samples described below, serovar Gallinarum was also isolated from 

In silico serotyping tools used by NCBI PD cannot differentiate between Gallinarum and Enteritidis, nor can they distinguish at the biovar level. Additional genetic features need to be incorporated for accurate serotyping.
