Investigating farm-level risk factors for Salmonella Dublin infection and on-farm transmission in British Columbian dairy farms
Salmonella Dublin (serotype D) is a cattle-adapted bacterial pathogen that has profound negative impacts on the dairy industry due to calf mortality, abortion, and reduced milk yield (Nielsen, 2013). In 2002, Denmark initiated a Salmonella Dublin surveillance and control program that classified herds as level 1 (most likely unaffected), level 2 (probably infected), and level 3 (bacteria detected; Nielsen and Nielsen, 2006).
A Retrospective Analysis of Postmortem Salmonella Dublin Cases in Dairy Cattle in British Columbia
1. Introduction Salmonella Dublin is a bovine-adapted bacterial pathogen that primarily affects dairy cattle [1]. Once S. Dublin enters a herd, it can spread quickly, often resulting in calf loss and abortions, but it can have an asymptomatic stage during initial infection [1]. Once present on farms, it can be difficult to eliminate as many animals become lifetime chronic carriers, resulting in intermittent bacterial shedding [1]. S.
A Retrospective Analysis of Postmortem Salmonella Dublin Cases in Dairy Cattle in British Columbia
Salmonella Dublin is a bovine-adapted bacterial pathogen that primarily affects dairy cattle. The incidence of S. Dublin has been increasing across North America, including strains that are multidrug resistant. In British Columbia, the Ministry of Agriculture’s Animal Health Center (AHC) reported an increase in cases since 2015, warranting an investigation into how S. Dublin is spreading within the province.
