First Time

A total of 17 endophytic fungal isolates were obtained from the leaves of Mentha cordifolia Opiz (Lamiaceae). Seven isolates were identified to the level of genus by using taxonomically relevant morphological traits. Colletotrichum and Phomopsis species were dominant among these strains. All strains were separated from M. cordifolia leaf for the first time. The ethyl acetate extracts of all endophytic fungi were tested for antibacterial activity against Salmonella typhimurium TISTR1166 and Pseudomonas aeruginosa TISTR781. Most endophytes exhibited antibacterial activity. Ustilago sp. MFLUCC15-1024 presented the highest inhibition zone diameter with a MIC of 31.25 μg/mL against the tested pathogens. The chemical composition of the ethyl acetate extract of this strain was investigated using gas chromatography-mass spectrometry. Twenty-one components were identified. 2-Phenylethanol (38.7%), E-ligustilide (12.4%), α-eudesmol (10.2%), β-vetivone (4.6%), β-ylangene (3.7%) and verbanol (3.4%) were the major components of the extract. The strong antibacterial activity of Ustilago sp. MFLUCC15-1024 ethyl acetate extract may be attributed to the presence of a high concentration of bioactive compounds including phenyl ethyl alcohol, E-ligustilide and α-eudesmol. The results indicate that there is high diversity of endophytic fungi in M. cordifolia leaf, and that Ustilago sp. MFLUCC15-1024 strain could be an excellent resource of natural antibacterial compounds.

The n- Hexane, ethyl acetate, methanol and distilled water Leaf, Stem, Flower and Fruit extracts of Moringa oleifera were evaluated for their antibacterial activity against six Gram-Negative and Gram-Positive bacteria and antifungal activity against seven fungal strains using Ciprofloxacin, Doxycycline, Fluconazole and Ketacozole as positive control. The activity was analyzed by well diffusion and two-fold serial broth dilution method of different extract. The study revealed that all the extracts irrespective of their types, in different concentrations inhibited growth of the test pathogens to varying degrees. Ethyl acetate extract showed maximum activity against all the bacterial strains followed in descending order by methanol, n-.Hexane and distilled water extracts. Ethyl acetate extract showed high antibacterial activity against Serratia marcescens (22mm) Methanol and n-Hexane extract were effective against Enterococcus faecalis and Bacillus subtilis (10mm) respectively. Aqueous extract showed maximum number of inhibition against Staphylococcus aureus (27mm) and Micrococcus luteus (18mm). Ethyl acetate extract showed maximum inhibition against Trichoderma harzianum (16mm) than other extracts were ineffective against selected fungus. MIC values were recorded as 0.125 to 4mg/ml. The phytochemical screening revealed the presence of phenols and flavonoids. Expression to these results it may be concluded that M. oleifera may be a potential source for the curing of various infectious diseases caused by the resistant microbes

Clove is one of the plants that has the potential as an antibacterial. Clove, besides being known as a food flavoring, also has properties as an analgesic, bacteriostatic, and treat stomach cramps. This study aims to isolate and obtain a chromatogram profile of clove flowers (Syzygium aromaticum L.) against bacteria that cause dental caries infection. The search for bioactive compounds in this study was to isolate endophytic fungi in clove flowers and then purified and tested macroscopically. Then a screening test was carried out and then continued for 21 days fermentation using Potato Dextrose Broth medium to separate the supernatant and mycelia, then extracted using ethyl acetate solvents to obtain ethyl acetate extract. Antibacterial activity testing was carried out by TLC-Bioutography method using ethyl acetate: n-hexane (4: 1) eluent. The results of this study obtained five endophytic fungi isolates that were active against the bacteria Streprococcus mutans and Porphyromonas gingivalis. Isolates that have the greatest activity, namely isolates with the code IFBC-01. The results of TLC-Bioautography obtained one speck with a value of rf: 0.67 which means it has antibacterial activity.

Aim: This study aimed to evaluate the antibacterial and antitubercular activities of ethylacetate and ethanol leaf extracts of Senna occidentalis. Study Design: Fresh leaves of Senna occidentalis collected from Suleja, Niger state were used for this study against some medically important micro-organisms viz; Staphylococcus aureus, Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Salmonella paratyphi, Klebsiella pneumoniae, Mycobacterium bovis and Mycobacterium smegmatis. Place and Duration of Study: The study was conducted in Abuja, Nigeria at the Department of Microbiology and Biotechnology, National Institute for Pharmaceutical Research and Development [NIPRD], from February 2019 to April 2019. Methodology: Senna occidentalis leaves were extracted successively with ethyl-acetate and ethanol. The obtained extracts were tested in vitro for antibacterial activity by agar well diffusion method, while anti-tubercular screening was carried out by broth micro-dilution method. A fixed-dose concentration of chloramphenicol was used as a control drug against the bacterial isolates while isoniazid was used as control drug against the mycobacterium isolates. Results: The in vitro antibacterial screening showed that the crude extracts exhibited varying activity against the different microbes with highest zone of inhibition at 12 mm, and anti-tubercular activity with MICs ranging from 97.6-390.6 μg/mL.  Among these extracts, ethyl-acetate extract showed significant antibacterial activity against most of the test micro-organisms. The most susceptible micro-organism was P. aeruginosa (12mm zone in ethyl-acetate at 80 mg/mL) followed by B. subtilis (10 mm zone in ethyl-acetate extract at 80 mg/mL) and E. coli (9 mm zone in ethyl-acetate extract at 80 mg/mL). The ethanol extract was the most effective in inhibiting the growth of M. smegmatis and M. bovis with MICs of 97.6 μg/mL and 195.3 μg/mL. Conclusion: The activities observed could be attributed to the presence of some active metabolites contained in the extracts which could be useful in drug development for therapeutic purposes.
