“…Thereof, 152 (70.7%) originated from sheep, 60 (27.9%) from goats, one from a dromedary (0.5%), and two isolates (0.9%) were of unknown origin. The dromedary with visceral pseudotuberculosis belonged to a camel farm in Switzerland and was imported two years prior to the clinical signs from a traveling circus in Germany [ 51 ]. The majority of the isolates (46.5%; n = 100) originated from healthy slaughtered sheep and goats; of these, 67 showed lesions in the lung.…”

Corynebacteriumpseudotuberculosis biovar Ovis is the etiological agent of the contagious and chronic disease caseous lymphadenitis (CLA) in sheep and goats. The economic impact of CLA in Switzerland remains largely unknown, and the transmission modalities, as well as the genetic diversity of circulating strains, are poorly understood. This work presents further characterization data for 215 C. pseudotuberculosis isolates from sheep, goats and a dromedary originating from Switzerland and the Principality of Liechtenstein, collected over a 15-year period. The isolates were classified into the two biovars Ovis and Equi, analyzed for the presence of the diphtheria-like toxin gene and characterized using MLSA. All sheep and goat isolates were classified as C. pseudotuberculosis biovar Ovis. The isolate from a dromedary was classified as biovar Equi. No isolates harboring the diphtheria-like toxin gene were detected. Phylogenetic analysis of the concatenated sequences of four genes revealed the existence of 24 clusters. There was no correlation between MLSA sequence types, year of isolation and the geographical origin of the isolates. These findings confirm the presence of several MLSA sequence types in the study area and over a 15-year period. Moreover, no sheep- and goat-specific MLSA sequence types were found.
