Salmonella Midway

An adult male of corn snake (Pantherophis guttatus) was found dead due to septic shock 48 hours after the consumption of a feeder mouse purchased online. Microbiological examinations of the snake and mouse livers revealed the presence of Salmonella enterica ser. Midway. To investigate whether the mouse was the source of infection for the snake, the two Salmonella isolates, from the snake and the mouse, were characterized and subjected to whole genome sequencing, to see if they belonged to the same strain. The genome analysis of the two isolates showed a highly correlation between them: they belonged to the strain type ST-357 for the classic MLST scheme, and to the strain type ST 171322 for the cgMLST scheme.
