Models of Clostridium difficile infection (C. difficile) have been used extensively for Clostridium difficile (C. difficile) research. The hamster model of C. difficile infection has been most extensively employed for the study of C. difficile and this has been used in many different areas of research, including the induction of C. difficile, the testing of new treatments, population dynamics and characterization of virulence. Investigations using in vitro models for C. difficile introduced the…

The observed community patterns suggest that successional dynamics following antibiotic treatment facilitate C. difficile establishment, and the similarities between the microbiome responses observed in this study and those reported in CDI-infected humans further support the utility of adult pigs as models for the study of CDI.

Comparison with the results of a previous gut model study showed that vancomycin was more effective than metronidazole in reducing C. difficile PCR ribotypes numbers and cytotoxin titres, possibly correlating with the extent of germination capacity.

In a gut model that simulates CDI, linezolid reduced the duration of cytotoxin production by C. difficile PCR ribotype 027 without influencing viable counts of vegetative forms of the organism and may reduce toxin levels, as reported in staphylococci and streptococci.

Tigecycline exposure did not induce C. difficile proliferation or cytotoxin production despite reduced competing microflora, and factors other than gut microfloras colonization resistance may contribute to the low risk of CDI induction.

It is shown that isogenic mutants of C. difficile producing either toxin A or toxin B alone can cause fulminant disease in the hamster model of infection, re-establish the importance of both toxin A and toxin B and highlight the need to continue to consider both toxins in the development of diagnostic tests and effective countermeasures against C. diffuse.

Tigecycline did not promote the establishment of colonization in mice, yet it did not reduce concentrations of C. difficile, probably due to inhibitory activity against C.difficile and relative sparing of indigenous anaerobic microflora.
