Pseudoscardovia radai is a species of Gram-positive, anaerobic, non-motile bacteria in the family Bifidobacteriaceae. It was first described in 2014 following isolation from the gastrointestinal tract of a wild boar (Sus scrofa scrofa) in the Czech Republic.
Pseudoscardovia radai was named and classified as part of a follow-up to the 2013 description of Pseudoscardovia suis. It shares many phenotypic traits with P. suis, but differs in specific fermentation and genomic properties.
Pseudoscardovia radai is a strictly anaerobic, rod-shaped, Gram-positive bacterium. It ferments carbohydrates and produces lactic acid as the major metabolic end product. Colonies are similar in appearance to those of P. suis but can be distinguished biochemically.
Pseudoscardovia radai was originally recovered from the gut of a wild boar. A metagenomic study found that Pseudoscardovia species, including P. radai, were more abundant in pigs raised outdoors compared to those raised indoors, indicating a link to natural or pasture-based environments.
The type strain of Pseudoscardovia radai is DPVI-TET3 (= DSM 24742 = CCM 7943).
