Salmonella in Chicken and Man
Some points on the Salmonella puzzle of chicken and man:
1. Salmonella Gallinarum (SG), S. Pullorum(SP), and S. Enteritidis(SE) share O9:O12 antigens; S. Typhimurium (ST) has O4:O5:O12
2. O9 antigen can induce many more antibodies than O12. So O12 antibodies in the chicken infected by SG or SP would protect the chicken from SE infection but not from ST infection.
3. SE do not affect the health of the Chicken too much that it is difficult to look for sick chicken infected by SE and remove them.
4. SE and ST can be carried by rodents (rats, mice, etc.)…removing sick chicken cannot help too much.
5. Vaccination is the best way to control SE and ST.
Best,
HS Kwan
