Affected animals show clinical symptoms like seromucoid
nasal discharges, nasal granuloma with miliary/cauliflower like unilateral/bilateral growths (cattle) and serous nasal discharge and pinhead sized granular eruptions (buffaloes).
The diagnosis and classification of the types of otitis media were based on: (i) clinical data of otalgia and otomicroscopic findings of opacity and bulging of the intact tympanic membrane for AOM; (ii) a wet, swollen and contourless eardrum for perforated AOM; (iii) evidence of seromucoid
effusion in the middle ear (completely filled or air-fluid level or bubbles), with an intact tympanic membrane without symptoms of acute infection for OME;  and (iv) evidence of a perforation or cholesteatoma with or without purulent discharge for CSOM.
The right-sided mass had previously ruptured into the right nostril, draining a seromucoid
1[degrees]C), cough, accelerated pulse and breath, seromucoid
nasal discharge, and leukopenia.
