Vaccine Detail
Zoosaloral H. |
Vaccine Information |
- Vaccine Name: Zoosaloral H.
- Target Pathogen: Salmonella spp.
- Target Disease: Salmonellosis
- Tradename: Zoosaloral H.
- Vaccine Ontology ID: VO_0004141
- Type: Live, attenuated vaccine
- Antigen: The antigen is a strain of S. Typhimurium called Zoosaloral H.
- Preparation: This live vaccine strain is derived by chemical mutagenesis from a virulent avian S. Typhimurium DT009 isolate. Chemical mutagenesis caused attenuation via adenine and histidine auxotrophy, but did not change the phage type of the vaccine strain (Frech et al., 1998).

Host Response |
Chicken Response
- Vaccination Protocol: One-day-old SPF chickens were inoculated orally with 0.1 ml of a Zoosaloral culture such that the birds received between 6 x 10^8 and 1 x 10^9 cfu each (Methner et al., 1997).
- Persistence: Not noted.
- Challenge Protocol: The birds were challenged 24 h later orally with 0.1 ml of a culture of nalidixic acid-resistant Salmonella derivative diluted in PBS such that each bird received 10^4 cfu(Methner et al., 1997).
- Efficacy: A significant amount of S. Typhimurium 421 was fund in the livers of the chickens after pretreatment and challenge (Methner et al., 1997).
