Salmonella in Animal Feeds Data: Evidence Gap Map

Study Design by Region and Serovar

Study Design


Analytical ObservationalDiagnostic test evaluationSingle group observationalMolecular studiesLaboratory study (experimental)Clinical / field trial with natural disease exposureChallenge trial in natural settingA single study may report more than one region or serovar, so study count may exceed the number of studies characterized. In addition, the serovarsincluded the top 10 across all five sectors. However, the number of serovars listed is greater than 10 because some serovars were studied an equalnumber of times. Moreover, studies that reported multiple regions (n = 6) were excluded from this map since data (e.g., serovars) were not extractedfor each individual region.
