The effect of biosecurity measures application on the level of diseases risk in different poultry farms

Abstract The development and implementation of a biosecurity plan in a poultry production enterprise, require a documented approach and scoring systems to rank biosecurity protocols and their implementation. Hence, this study was carried out to monitor some biosecurity measures applied in different poultry farms and its effect on the presence of some pathogenic bacteria, such as E. coli, Pasteurella and Campylobacter in different poultry farm's production. The obtained results showed that the highest incidence of isolated pathogenic bacteria was in the duck farms. The incidence of E.coli spp was (61%), Pasterulla spp was (18.52%) and Campylobacter spp was (43.5%) in duck farms. There was a negative relationship between the application of biosecurity measures and the isolation of pathogenic bacteria in poultry farm's production. The EaeA and Stx1 virulence genes were detected from some serotypes of E.coli; while the virulence genes pfhA and hgbB were isolated from some P. multocida serotypes. Also, the cdtB and cdtC virulence genes were recovered from Campylobacter serotypes. Finally, the biosecurity measures are essential for the success of poultry production. Indeed, biosecurity measures reduce the risk of introducing pathogens during the poultry production cycle; In addition, it reduces financial losses through decreased mortality rates and treatment costs.
