Background: Salmonella enterica subsp. enterica serovar Newport (antigenic formula 6,8,20:e,h:1,2) is a serovar of the O:8 (C₂-C₃) serogroup. According to the National Veterinary Services Laboratories (NVSL), serovar Newport became one of the top 10 most frequently identified Salmonella serotypes from US cattle from July 1998 through June 1999. Ranked as one of the top three Salmonella serotypes causing US foodborne outbreaks, serovar Newport has seen a substantial increase in human clinical cases since 1995, with an estimated 100,000 annual infections. In recent years, multidrug resistant Salmonella Newport has emerged as an epidemic, rapidly spreading through animal and human populations in US. In 2019, serovar Newport ranked as the fifth most prevalent Salmonella serotype in the EU/EEA, representing 1.1% of reported human salmonellosis cases.
