  On the identity of the poorly known spider species Centromerus obscurus Boesenberg, 1902 and description of a new species (Araneae: Linyphiidae) Abstract The taxonomic status and distribution of the poorly known linyphiid species Centromerus obscurus Boesenberg, 1902 is discussed on the basis of newly collected material from Bulgaria. Additionally, after a review of the related literature and the newly collected material, a new species of Centromerus species, C. thaleri sp. n., is described based on both sexes and Centromerus obscurus is considered nomen dubium stat. reconf.  Deltshev, C. & Indzhov, S.

Reptile Exposure in Human Salmonellosis Cases and Salmonella Serotypes Isolated from Reptiles, Ontario, Canada, 2015–2022

Abstract


Reptile-associated outbreaks of human Salmonella infections are increasing in Canada, coinciding with a rise in the popularity of reptiles as pets. We conducted a retrospective analysis of surveillance data for human Salmonella case-patients in Ontario during 2015–2022. We compared serotypes and reptile types for those reporting domestic reptile or amphibian exposure with veterinary Salmonella isolates reported during the same period. Case-patients commonly reported contact with reptile types from which Salmonella was most frequently isolated. Some serotypes from human case-patients were closely associated with contact with specific reptile types, including Salmonella Paratyphi B biovar Java (Salmonella Paratyphi B variant L (+) tartrate +) with snakes, Salmonella Agbeni with turtles, and Salmonella Cotham, Salmonella Chester, and Salmonella Tennessee with bearded dragons. Salmonella was most likely to be reported from reptiles fed a carnivorous diet. Education of reptile owners could help promote proper veterinary care and reduce transmission of zoonotic infections.
