Lima, Danya Bandeira; Torres, Alba Fabíola Costa; Mello, Clarissa Perdigão; Menezes, Ramon Róseo Paula Pessoa Bezerra; Sampaio, Tiago LimaAims: Dinoponera quadriceps venom (DqV) was examined to evaluate the antibacterial activity and its bactericidal action mechanism against Staphylococcus aureus. Methods and Results: DqV was tested against a standard strain of methicillinsensitive Staphylococcus aureus (MSSA), Staph. aureus ATCC 6538P and two standard strains of methicillin-resistant Staphylococcus aureus (MRSA), Staph. aureus ATCC 33591 and Sta...

Pantoja, Lydia Dayanne Maia; Moreira Filho, Renato Evando; Brito, E.H.S.; Aragão, T. B.; Brilhante, Raimunda Sâmia Nogueira; Cordeiro, Rossana de AguiarThe aim of this study was to evaluate the presence of Þlamentous fungi and yeasts on the external surface of ants at hospitals. From March 2007 to February 2008, 2,899 ants were evaluated in two public hospitals in the city of Fortaleza, Ceara ́ , in northeastern Brazil. The ants were attracted by nontoxic baits, distributed within critical and semicritical hospital areas. The fungi were identiÞed through macro...

Lopes, Kamila Soares; Rios, Emiliano Ricardo Vasconcelos; Lima, Camila Nayane de Carvalho; Linhares, Maria Isabel; Torres, Alba Fabíola CostaArthropod venoms are potential sources of neuroactive substances, providing new tools for the design of drugs. The aim of this study was to evaluate the effects of Dinoponera quadriceps venom (DqV) on seizure models in mice induced by pentylenetetrazole (PTZ), pilocarpine, and strychnine. In the PTZ model, intraperitoneal treatment with DqV (0.5 mg/kg) increased the time until the first seizure and the percenta...
