Resumo(s)
The results in this work evaluated the sensitivity and specificity of the olfactory capacity of the intervening dog in the fungus biodetection. On 100 attempts, a sensitivity and a specificity of 100% (Table 1) were obtained for the biodetection of the fungus Sclerotium rolfsii when the 4-year-old English Springer Spaniel female dog was faced to a straight line of 5 equally distanced Falcons.
The post-inoculation time of the samples, used in the sessions, varied between 24 and 72H, however there was no difference in the detection response by the female dog Julieta. This is also a noteworthy additional fact, given the potential for prevention that can represent the detection of a fungus with such a short post-inoculation time. Further work is being established to assess the olfactory ability to detect the presence of the fungus in inoculated turfgrass samples and finally to detect it in the field.
