Objectives: Grewia paniculata (Family: Malvaceae) has been used to treat inflammation, respiratory disorders and fever. It is additionally employed for other health conditions including colds, diarrhea and as an insecticide in Bangladesh. The aim of the present study was to investigate the antibacterial and cytotoxic activities of different extracts of Grewia paniculata. Materials and Methods: ...

OBJECTIVE Quinolone resistance is usually caused by various chromosomal mutations, but has been more recently associated with plasmids which carry the qnr determinant. The aim of this study is to investigate the prevalence of qnr genes in clinical isolates of Enterobacteriaceae in Jamaica. METHODS A total of 255 non-duplicate fluoroquinolone-resistant Enterobacteriaceae clinical isolates, com...

WCK 771 demonstrated MIC(50) and MIC(90)s of 0.03 and 1 microg/ml, respectively, against 297 recent U.S. community-acquired and hospital strains of Staphylococcus aureus, irrespective of quinolone or glycopeptide resistance. Against quinolone-resistant strains, MIC(90)s of WCK 771 and moxifloxacin were 1 and 16 microg/ml, respectively.

BACKGROUND & OBJECTIVES Several chemical compounds isolated from natural sources have antibacterial activity and some enhance the antibacterial activity of antibiotics reversing the natural resistance of bacteria to certain antibiotics. In this study, the hexane and methanol extract of Cordia verbenaceae were assessed for antibacterial activity alone and combinated with norfloxacin against the ...

The objective was to analyse the antibacterial ability of members of the intestinal microbiota of Oncorhynchus mykiss specimens on several bacterial target strains that contaminate food and cause disease in humans. Bacterial colonies from an intestinal portion of the 20 specimens of O. mykiss were obtained in different culture media. Several of the colonies showed antibacterial action on differ...

Infectious diseases are one of the main causes of high morbidity and mortality in human beings around the world. Currently the marine is an important source of medicinal products since the marine ecosystem,particularly seaweeds are directly exposed and are susceptible to ambient micro organisms such as bacteria fungi and viruses. In the present study, we assessed the antibacterial and antifunga...

It is widely accepted that all organisms have processes that maintain their state of health. Failure of these processes, such as those involving the naturally occurring antibacterial peptides, may lead to pathological events. Recent results demonstrate that these peptides, such as peptide B, appear in invertebrates and vertebrates (including humans) immediately after tissue trauma, and maintain...
