Introduction: This communication describes a retrospective study of the epidemiology of snakebite cases that were recorded from 2007 to 2012 in the State of Piauí, northeastern Brazil. Methods: Data were collected from the Injury Notifi cation Information System database of the State of Piauí's Health Department. Results: A total of 1,528 cases were identifi ed. The cases occurred most frequently in rural areas between January and July. Victims were predominantly male farmers, and were typically 30-39 years old. Most victims were bitten on the foot, and received medical assistance within 1-3h after being bitten. Conclusions:The epidemiological profi le of snakebites in the State of Piauí is similar to that in all of Brazil.

Sida planicaulis, popularly known as "vassoura", is very common in Curimataú Paraibano, although little studied in relation to its antimicrobial potential. This study aimed to investigate the antifungal activity of the crude ethanolic extract and its phases: hexane, chloroform, aceto- and hydroalcoholic phase of the plant on the filamentous fungi Rhizopus oryzae, Exophyala werneckii, Aspergillus niger, Aspergillus flavus, Trichophyton mentagrophytes, Cladosporum 2B3 and Microsporum canis. The antifungal activity was verified by the propagation technique in Agar. Incubation was carried out in a bacteriological oven at 28ºC for 7 to 15 days. The antifungal activity was evaluated by the values of the inhibition halos, the concentration of the Minimal Inhibitory by the microdilution technique, where all testes were performed in triplicate. The results showed antifungal activity against the microorganism Trichophyton mentagrophytes, the values of the inhibition halos varied between 15 and 36 mm, Third, species of extract and phases are not an antifungal activity. It can be concluded that the samples used are specific to the inhibitory plane against the fungus T. mentagrophytes, but did not obtain the units used for the development of a new antifungal.
