Identification of a new Salmonella serovar – Salmonella Weitmar (8:z41:1,5)

We report the first human case of a novel <i>Salmonella enterica</i> serovar <i>Weitmar</i> (8:z41:1,5), isolated from a 41-year-old outpatient with acute diarrhea and fever in Bochum, Germany. Identification involved culture, multiplex PCR, MALDI-TOF MS, biochemical testing, and reference lab serotyping. The strain showed a unique antigenic profile and was confirmed by the WHO Collaborating Centre for Reference and Research on <i>Salmonella</i>. This case illustrates a routine but essential aspect of microbiological surveillance, highlighting how combined diagnostics and international collaboration support the reliable identification of novel <i>Salmonella serovars</i>.
