background: the appearance of multi-drug resistant microorganisms is becoming a global problem. already several strategies have been employed for overcoming antibiotic resistance issue. developing new antimicrobial compounds from microbial source could be a beneficial solution. hence screening programs in order to discover new antibiotics from microbial entities is interesting. because of high ...

The efficacy of four fungal bioagents viz., Trichoderma hamatum, Trichoderma harzianum, Trichoderma viride, Gliocladium virens and two bacterial bioagents namely Pseudomonas fluorescens and Bacillus subtilis were evaluated against the chickpea vascular wilt pathogen, Fusarium oxysporum f.sp. ciceri in vitro condition using Dual Culture Technique. Among the fungal bioagents, T. harzianum produce...

The purpose of this study was to assess the antibacterial activity an ethanolic extract Derris scandens against clinically isolated human pathogenic bacteria. Materials and methods: assessed for ten bacteria at different concentrations (25 - 100 μg/ml) through agar well diffusion method. Group 1 (25μg/ml), 2 (50μg/ml), 3 (75μg/ml) 4 (100μg/ml), 5 (positive control), 6 (negative control) calcula...

Four new para-benzoquinone containing abietane-type diterpenoids (1-4) along with thirteen known diterpenoids (5-17) were isolated from the roots of Plectranthus punctatus. The structures of the compounds were established by detailed spectroscopic analyses and comparison with literature data. The compounds were tested for their antibacterial and cytotoxic activity and showed significant inhibit...

We screened forty crude extracts of twenty commonly used to treat bacterial infections for broad sp more affordable alternative against resistant organisms common pathogenic gram negative and gram positiv diffusion method followed by the tube dilution method extract, Escherichia coli showed sensitivity to zone of inhibition ranging from 7 – 19mm, fifteen Pseudomonas aeruginosa was sensitive to ...

The antibacterial activities of the methanolic leaf and bark extract of Persea americana was tested in vitro on bacterial isolates namely: Streptococcus pyogenes, Proteus mirabilis, Salmonella typhi, Klebsiella pneumoniae, Escherichia coli, Bacillus subtilis (NCIB 3610), Staphylococcus aureus (NCIB 8588), Escherichia coli (NCIB 86), Klebsiella pneumoniae (NCIB 418) and Pseudomonas aeruginosa (N...

This study attempts to investigate the antibacterial effectiveness of three varieties garlic (single garlic, kating and black garlic) on growth Enterobacteriaceae bacteria (Escherichia coli, Enterobacter sp, Klebsiella sp. from chicken meat samples. Treatment Kating single at concentrations 20%, 40%, 60%, 80%, 90%, 100%. observed inhibition zone Muller Hinton Agar (MHA) media that had been plan...

Pulpal and periradicular diseases are primarily caused by bacterial invasion of the root canal system as a result of caries progression. The presence of residual bacteria at the time of root canal completion (obturation) is associated with significantly higher rate of treatment failure. Re-infection of obturated root canals can be potentially prevented by enhancing the antibacterial activities ...

Ona cina (Lantana camara) is a plant that has the ability as an anti-bacterial. The bioactive compounds of ona anti-bacterial are flavonols and lantanilic acid. This study aimed to compared methanol extract leaves roots in inhibiting growth Staphylococcus aureus Pseudomonas aeruginosa. research laboratory experimental using well diffusion method with 24 treatments. treatment was repeated 2 time...
