Antibacterial activity of venom from funnel web spider Agelena labyrinthica (Araneae: Agelenidae)
(Bmc, 2008)Since the number of microorganisms that are resistant to antibiotics has been increasing steadily, the need for combating these pathogens requires new pharmaceutical agents. To produce these substances, new models have ... -
Loxosceles spider bite in Turkey (Loxosceles rufescens, Sicariidae, Araneae)
(Cevap-Sao Paulo State Univ-Unesp, 2008)Loxoscelism is caused by envenomation by spiders that belong to the Loxosceles genus. In loxoscelism, a local necrotic lesion appears and, in many cases, loxoscelism or necrotic araneism is considered a serious public ... -
Antimicrobial activity of various extracts of Ocimum basilicum L. and observation of the inhibition effect on bacterial cells by use of scanning electron microscopy
(African Networks Ethnomedicines, 2008)The antimicrobial activities of chloroform, acetone and two different concentrations of methanol extracts of Ocimum basilicum L. were studied. These extracts were tested in vitro against 10 bacteria and 4 yeasts strains ... -
