Abstract		An indirect enzyme linked immunosorbent assay (ELISA) was developed and its diagnostic potential evaluated for rabbits infected by Trichophyton mentagrophytes. Within-run and between-run coefficient of variance varied from 2.3 to 7.7% and from 5.9 to 8.5%, respectively, indicating satisfactory reproducibility of the ELISA. There was no significant cross-reaction with antigens of Microsporum canis, Malassezia pachydermatis and Aspergillus fumigatus. The level of specific IgG to Trichophyton mentagrophytes was measured in sera of 25 11-week-old and 12 younger infected rabbits. There was no significant difference in the IgG level between 12 5-week-old infected rabbits and controls (p = 0.38). The antibody response was higher in 12 7-week-old rabbits compared with controls (p = 0.001 ). The IgG level in 25 11-week-old rabbits differed from the controls very significantly (p < 0.0001). Increased specific IgG in 11- week-old rabbits exhibited 96% sensitivity and 94% specificity. Predictive values of a positive and a negative test were 96 and 94%, respectively. Western immunoblotting associated three protein bands (21.5, 31, 44 kDa) with Trichophyton mentagrophytes infection.
