Efficacy of Oral Rabies Vaccine Baits Containing SPBN GASGAS in Domestic Dogs According to International Standards.

(1) Background: The oral vaccination of free-roaming dogs against rabies has been developed as a promising complementary tool for mass dog vaccination. However, no oral rabies vaccine has provided efficacy data in dogs according to international standards. (2) Methods: To test the immunogenicity and efficacy of the third-generation oral rabies virus vaccine strain, SPBN GASGAS, in domestic dogs, dogs were offered an egg-flavoured bait containing 3.

Pathogens Detected in 205 German Farms with Porcine Neonatal Diarrhea in 2017.

Neonatal diarrhea (ND) is still a frequently observed problem in modern industrial pig production. ND is predominantly caused by bacterial and viral pathogens. The objective of this study was to give an overview of different pathogens involved in ND in Germany.

T-Cell Cytokine Response in Typhimurium-Vaccinated versus Infected Pigs.

Vaccination with the live attenuated vaccine Salmoporc is an effective measure to control Typhimurium (STM) in affected swine populations. However, the cellular immune response evoked by the Salmoporc vaccine including differences in vaccinated pigs versus non-vaccinated pigs upon STM infection have not been characterized yet. To investigate this, tissue-derived porcine lymphocytes from different treatment groups (vaccination-only, vaccination and infection, infection-only, untreated controls) were stimulated in vitro with heat-inactivated STM and abundances of IFN-γ, TNF-α and/or IL-17A-producing T-cell subsets were compared across organs and treatment groups.

Invasion inhibition effects and immunogenicity after vaccination of SPF chicks with a Salmonella Enteritidis live vaccine.

Objective: Meat and eggs from chickens infected with Enteritidis, Typhimurium and Infantis are considered to be an important source of infections for humans. In order to control infections in chickens, basic biosecurity measures are taken in combination with inactivated or attenuated live vaccines. Apart from an adaptive immune response, some live vaccines also induce innate immune mechanisms that prevent or inhibit systemic invasion with homologous serovars.

Vaccination and Infection of Swine With Typhimurium Induces a Systemic and Local Multifunctional CD4 T-Cell Response.

The gram-negative facultative intracellular bacteria Typhimurium (STM) often leads to subclinical infections in pigs, but can also cause severe enterocolitis in this species. Due to its high zoonotic potential, the pathogen is likewise dangerous for humans. Vaccination with a live attenuated STM strain (Salmoporc) is regarded as an effective method to control STM infections in affected pig herds.
