Abstract

Tuberculosis is an infectious disease that affects ruminants, causing losses in milk and meat production. Thus, the aim of this research was to compare the cutaneous response of the comparative cervical tuberculin test in buffaloes. Thus, the Comparative Cervical Test (CCT) examined 473 buffaloes, with 440 females and 33 males of different ages and races. Measurement of the allergic skin response was performed at 24, 48, 72 and 96 hours after tuberculinization. For avian tuberculin, the mean skin increases ranged from 12.24mm (0 hour) to 14.82mm (96 hours). As for bovine tuberculin ranged from 11.99mm (0 hour) to 13.68mm (96 hours). The maximum point of measurement of the allergic skin reaction was observed at 72 hours after the application of avian tuberculin, the same was observed for bovine tuberculin. However, there was no statistically significant difference in relation to the amplitude of the reactions observed at 48, 72 and 96 hours. Therefore, it was concluded that the skin allergic reaction occurred in a gradual manner and that the maximum amplitude value of the cutaneous allergic response in buffalo in the diagnosis of tuberculosis was at 72 hours.
