Background: The antimicrobial effect of Warburgia ugandensis has been recognized for many years in developing countries especially East Africa. However, limited investigations have focused on its microorganisms causing urinary tract infection.
 Objective: To determine the activity selected standard that cause infections i.e. Escherichia coli (ATCC 25922), Candida albicans 10231), Proteus m...

Dryopteris crassirhizoma is traditionally used as an herbal remedy for various diseases, and has been identified in a previous study as a potential anti-caries agent. In this study, the effect of a methanol extract of D. crassirhizoma on the viability, growth and virulence properties of Streptococcus mutans, a cariogenic dental pathogen, was investigated. In addition, the phytochemical composit...

The MICs of 21 beta-lactam antibiotics were measured against 126 clinically significant and epidemiologically unrelated Yersinia enterocolitica isolates. The most active antimicrobial agents tested (geometric means of MICs) were ceftriaxone, cefotaxime, ceftizoxime, and cefmenoxime (0.06 to 0.08 micrograms/ml). Mezlocillin (1.36 micrograms/ml) and piperacillin (1.57 micrograms/ml) were the most...

Background: Red betel (Piper crocatum) is a plant that grows lot in the tropics, especially Indonesia. The use of red tropical area, leaves for medicine due to fact contain essential oils. Purpose: To examine antibacterial activity leaf extract against Staphylococcus aureus by investigate at minimum inhibitory concentration (MIC) and bactericidal (MBC) values. Methods: This study used an vitro ...

Bacterial epiphytes isolated from marine eukaryotes were screened for the production of quorum sensing inhibitory compounds (QSIs). Marine isolate KS8, identified as a Pseudoalteromonas sp., was found to display strong quorum sensing inhibitory (QSI) activity against acyl homoserine lactone (AHL)-based reporter strains Chromobacterium violaceum ATCC 12472 and CV026. KS8 supernatant significantl...

The aim of this study was to determine the antimicrobial effect of Helichrysum arenarium L. essential oil in "invitro" condition on the growth of seven microbial species including Bacillus subtilis, Escherichia coli, Staphylococcus aureus, Saccharomyces cereviciae, Candida albicans, Aspergillus flavus and Aspergillus parasiticus using micro-dilution method. The minimum inhibitory concentration ...

The gastric pathogen Helicobacter pylori has developed resistance to virtually all current antibiotics; thus, there is a pressing need to develop new anti-H. pylori therapies. The goal of this work was to evaluate the antibacterial effect of oligo-acyl-lysyl (OAK) antimicrobial peptidomimetics to determine if they might represent alternatives to conventional antibiotic treatment of H. pylori in...

We evaluated the in vivo activity of levofloxacin alone or in combination with imipenem or amikacin in a mouse model of Acinetobacter baumannii pneumonia using a susceptible strain and one with low-level resistance (MIC/MBC of levofloxacin: 0.06/0.06 and 4/4 mg/L, respectively). As demonstrated previously with other pathogens, the AUC/MIC ratio predicted the efficacy of fluoroquinolones against...

Background: Centella asiatica leaves ethanol extract (CALEE) has higher concentration compared to other structures within the plant. The contains alkaloids, saponins and flavonoids, which play an active role as antioxidant antibacterial. Current study aimed determine effect of CALEE on Proteus mirabilis, vulgaris, Yersinia enterocolitica, Gram-negative bacteria that cause diarrhea. Materials me...
