Microbiology Unit, University of Louvain, Brussels, Belgium.

An enzyme-linked immunoassay (ELISA) with 11 Clostridium difficile serogroup-specific antisera was applied for serogrouping of C. difficile colonies from 314 consecutive positive fecal samples. Two hundred forty-nine strains (79%) were correctly serogrouped, 57 (18%) belonged to serogroups other than the 11 which were evaluated and gave a negative reaction with all antisera, and 8 isolates (2.5%) did not react with their corresponding antisera. ELISA is a rapid and reliable method for serogrouping C. difficile and should allow for the automation of this procedure.

D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D016360	Clostridioides difficile	A common inhabitant of the colon flora in human infants and sometimes in adults. The type species Clostridioides difficile is formerly known as Clostridium difficile. It is a causative agent for CLOSTRIDIOIDES INFECTIONS and is associated with PSEUDOMEMBRANOUS ENTEROCOLITIS in patients receiving antibiotic therapy.	Clostridium difficile
