Susceptibility of strict and facultative anaerobes Isolated from endodontic infections to metronidazole and beta-lactams

Journal of Applied Oral Science, 2007
Endodontic infections are mixed aerobic-anaerobic infections and several microbial groups associated to these pathologies are also involved in orofacial infections. The goal of this study was to evaluate the susceptibility of microorganisms isolated from

Metalo-beta-lactamases [PDF]

Jornal Brasileiro de Patologia e Medicina Laboratorial, 2006
Nos ultimos anos tem sido observada maior incidencia de bacilos Gram-negativos resistentes a cefalosporinas de espectro ampliado no ambiente hospitalar, ocasionando, assim, maior uso de betalactâmicos mais potentes, como os carbapenens. A utilizacao de carbapenens exerce maior pressao seletiva sobre a microbiota hospitalar, o que pode ocasionar aumento
