An integrated typing service for the surveillance of Salmonella in chickens
Summary The industry will directly benefit from this project immediately. SA Pathology currently processes up to 6,000 Salmonella isolates submitted from the industry. There is no charge made for this service. If a charge ($25 per isolate) were to be levied, the cost of conventional typing alone would be in excess of $150,000 per annum.

Improved understanding of the population structure and source of Salmonella outbreaks can lead to reduced contamination of the food supply. This could lead to improved control measures and subsequently less human morbidity as a result of Salmonella infection. In addition the research will reinforce the public perception that the industry has a commitment to food safety and public health issues.

A state of the art method of organism typing that can be used for organism tracing in an outbreak scenario and in the surveillance of Salmonella isolates submitted by the chicken meat industry that will enhance the understanding of the strains of pathogenic bacteria that may exist in food sources, human beings and the environment.

The rapid availability of a typing method for any Salmonella serovar of concern to the industry

Research organisation SA Pathology trading as the Institute of Medical & Veterinary Science (IMVS)
Objective summary A free (up to 6,000 tests per annum) and discreet conventional and where appropriate,
molecular based, typing service would continue to be offered to the industry.
To MLVA type Salmonella Typhimurium to a maximum of 700 (on average 600 S.
Typhimurium are received from broilers each year based on 200507 figures) and up to 300 selected S. Typhimurium isolates derived from humans.
To provide nonMLVA molecular typing for other industry related serovars on an "as
needed" basis.
To investigate the stability of MLVA loci in an in vivo chicken model

A major outcome of the project will be to provide a rapid integrated MLVA and phage typing service (and continuity) to the industry in the period of initial transition from phage typing to MLVA typing.
