Serological study of salmonella Dublin carriage in cows in khenchela, Algeria

Abstract

The objective of this study is to estimate the seroprevalence of S. Dublin infection in healthy cows in the Khenchela region and to identify potential risk factors that may be associated with the presence of S. Dublin antibodies. 194 cows sera from 35 farms were tested using an enzyme-linked indirect immunosorbent assay (ELISA) and the results showed a prevalence of 9.23% (18/194, 95% CI 5.17-13.29). The logistic regression model indicates that none of the factors tested were found to be significantly associated with S. Dublin seropositivity. We concluded that S. Dublin circulates in cattle farms in the Khenchela region of Algeria. In addition, we recommend the implementation of hygiene practices and biosecurity measures on farms to reduce the spread of infection and the use of vaccination in animals and people at risk.
