Bauhinia variegata is well-known medicinal plant used from the ancient era to till date for their medicinal values. The methanolic extract of Bauhinia variegata barks was screened for phytochemical constituents, antioxidant, phytotoxic and microbial activity. The microbial activity was tested against Staphylococcus aureus, Bacillus subtilis, Escherichia coli and Salmonella typhi at different concentration of 10, 15 and 20 mg/mL by agar well diffusion method. The plant extract showed the potent antimicrobial activity against the Staphylococcus aureus, Salmonella typhi, Bacillus subtilic and Escherichia coli with zone of inhibition 14 mm, 12mm, 14mm and 11mm respectively. Phytochemical analysis of the extract revealed that the antioxidant and antimicrobial activity of the plant materials is due to the presence of active secondary metabolites. In DPPH free radical scavenging assay the IC50 value of Bauhinia variegata was found to be 6.48±0.08 ?g/mL, while the IC50 value of the reference standard ascorbic acid was 45.93?g/mL. The extract of Bauhinia variegata, contains high value of phenolic (156.30±0.3 mg GAE/gm) and flavonoid (16.04±1.4 mg QE/gm) content exhibited the high antioxidant activity. The in-vitro phytotoxic bioassay showed 65%, 40%, and 25% growth regulation at just higher conc. of 1000, 100 and 10 ?g/mL with number of fronds 07, 12 and 15 respectively with respect to standard drug Paraquat of concentration 0.015?g/mL.Journal of Institute of Science and Technology, 2015, 20(2): 37-41

The medicinal value of the plants is due to their chemical components that bring a definite physiological action on the human body to prevent the diseases. In this work, we investigated the antimicrobial activity of leaves’ extracts of Quercus robur L., collected from the Algerian upper highlands, on ten bacterial strains and one fungal strain known to be pathogenic. First, we performed a qualitative phytochemical analysis, and second, antimicrobial activity tests performed by agar diffusion method (disc and well) with the determination of MIC by broth macro-dilution method. Given the results, it appears that obtained macerates of Quercus robur L. were rich in bioactive phytoconstituents such as alkaloids, anthraquinones, saponins, tannins, and other components. The yield of aqueous and methanolic macerates of leaves was 8.5 ± 1.41 and 22.4 ± 4.36%, respectively. The bacterial resistance was relatively important to several antibiotics, namely, ampicillin, amoxicillin + clavulanic acid for strains of Escherichia coli and Salmonella sp. However, Staphylococcus aureus strains were resistant to fusidic acid, penicillin, and oxacillin; while Enterococcus faecalis was resistant to fusidic acid, penicillin, oxacillin, and ticarcillin. The antibacterial activity of the macerates toward tested microbial strains showed that the aqueous and methanolic macerates of the leaves were proportional to the tested concentration and active not only against Gram-positive and Gram-negative bacteria but also on the fungal species Candida albicans. The estimated MIC for Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus was in the order of 10 mg/mL, which seems more effective than toward Salmonella sp., Klebsiella pneumoniae, Pseudomonas aeruginosa, and Candida albicans which were in the order of 30 mg/mL. These preliminary results confirm that the part of the studied plant had a very good antimicrobial activity that was proportional to the serial concentrations of the tested extracts.

Ayurvedic medicines are being used increasingly to fight or prevent common diseases. Udhara vayuhara churna is a polyherbal formulation containing Piper longum (Piperceae) Zingiber officinalis (Zingiberaceae), Elettaria cardamom (Zingiberaceae), Plumbago zeylanica (Plumbaginaceae), Carum carvi (Umbelliferae), Acorus calamus (Araceae) and Embilica officinalis (Euphorbiaceae). Methanolic and aqueous extracts of Udhara vayuhara churna were screened for their antimicrobial activity against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Aspergillus niger and Candida albicans. The results of antimicrobial activity of aqueous and methanolic extracts of the Udhara vayuhara churna indicated that methanolic extract inhibited the growth of one or more test pathogens than aqueous extract. Udhara vayuhara churna formulation extracts showed a broad spectrum of antimicrobial activity. Phytochemical investigation revealed the presence of tannins, saponins, alkaloids, glycosides, flavonoids and essential oils. This may be due to the multifunctional effect of all the seven plant ingredients of Udhara Vayuhara churn.

Cow’s milk containing pathogenic bacteria is an important threat to the consumers. The objectives of the present study were to identify the bacterial agents of public health importance in milk samples (n=35) of different locations and to determine their sensitivity to different antibiotics. The milk samples were collected and transported aseptically and subsequently allowed for culture in bacteriological media, Gram’s staining and biochemical tests for the identification of bacterial species. The bacteria identified were Staphylococcus aureus, Escherichia coli and Salmonella typhi, and their prevalence, in case of vendor milk specimens (n=28), were 96.43%, 53.57% and 35.71% respectively, and of brand milk specimens (n=7), were 42.86 %, 28.57% and 0%, respectively. This suggests that cautionary measures should be taken for quality milk production and consumption. The antibiotic sensitivity test was done by disc diffusion method and the average inhibition zones, in case of Staphylococcus aureus, were 32 mm for oxytetracycline, 26 mm for amoxicillin, 35 mm for ciprofloxacin, 27 mm for cefotaxime, 30 mm for ceftriaxone, 30 mm for azithromycin, and 26 mm for erythromycin; in case of Escherichia coli, were 5 mm for oxytetracycline, 9 mm for amoxicillin, 22 mm for ciprofloxacin, 30 mm for cefotaxime, 31 mm for ceftriaxone, 15 mm for azithromycin, and 0 mm for erythromycin; in case of Salmonella typhi., were 25 mm for oxytetracycline, 24 mm for amoxicillin, 38 mm for ciprofloxacin, 31 mm for cefotaxime, 34 mm for ceftriaxone, 24 mm for azithromycin, and 0 mm for erythromycin. Therefore, ciprofloxacin and ceftriaxone may be the antibiotics of first choice, and cefotaxime and azithromycin may be the second choice among the test antibiotics for the treatment of illness caused by these bacteria.Asian J.

Fluoroquinolones are critical antimicrobials for both human and veterinary medicine. Due to their unique mechanism of antimicrobial action and good pharmacokinetic properties, they are often the first choice drugs in the treatment of bacterial infections in animals. The purpose of the investigation was to study the antimicrobial activity of a third-generation fluoroquinolone antibiotic of danofloxacin against bacteria, pathogens of respiratory and intestinal infection in goats. The samples of the nasal outflows (respiratory infection) and fecal masses (intestinal infection) were collected from clinically ill goats for microbiological studies. The sensitivity test of the microflora of the biomaterial, carried out by the disco-diffusion method, showed that the microorganisms of all the samples were sensitive to danofloxacin. Bacteria Streptococcus pneumonia (n = 10), Staphylococcus aureus (n = 4) and Escherichia coli (n = 2) were isolated and identified from nasal exudate samples (n = 10). Pathogenic strains of Escherichia coli were isolated from all faecal samples (n = 12). The degree of bacteriostatic activity of danofloxacin was determined by establishing its minimum inhibitory concentration (MIC) for bacterial isolates by sequential dilutions in a liquid nutrient medium. The average MIC of danofloxacin for Streptococcus pneumoniae isolates was 0.26 ± 0.13 μg/ml and for Staphylococcus aureus isolates – 0.25 ± 0.075 μg/ml. For Escherichia coli strains isolated from faeces of goats suffering from coli infection, the average MIC of danofloxacin was 0.38 ± 0.12 μg/ml (range 0.2 to 0.8 μg/ml). Antimicrobial sensitivity testing have shown a high level of bacteriostatic activity of danofloxacin against bacteria, pathogens of respiratory and intestinal infections in goats. This may be the argument for the use of danofloxacin-based chemotherapeutic agents in the treatment of bacterial infections in goats, especially for the empirical approach to therapy.

Rhizosphere Fungi

Endophytic and rhizosphere fungi are understood to be aiding the host plant to overcome a range of biotic and abiotic stresses (nutrition depletion, droughts, etc.) hence, they remain to be reservoirs of plethora of natural products with immense use. Consequently, this investigation of endophytic and rhizosphere fungi isolated from Mikania cordata (a perennial vine that is well established in Sri Lanka) for their antimicrobial properties was performed with the aim of future derivation of potential beneficial pharmaceutical products. Leaves, twigs, and roots of M. cordata were utilized to isolate a total of 9 endophytic fungi out of which the highest amount (44%) accounted was from the twigs. A sample of the immediate layer of soil adhering to the root of M. cordata was utilized to isolate 15 rhizosphere fungi. Fusarium equiseti and Phoma medicaginis were endophytes that were identified based on colony and molecular characteristics. The broad spectrum of antimicrobial activity depicted by F. equiseti (MK517551) was found to be significantly greater (p≤0.05, inhibitory against Bacillus cereus ATCC 11778, Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Pseudomonas aeruginosa ATCC 25853) than P. medicaginis (MK517550) (inhibitory against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Pseudomonas aeruginosa ATCC 25853) as assessed using the Kirby-Bauer disk diffusion method. Trichoderma virens and Trichoderma asperellum were rhizospere fungi that exhibited remarkable antimicrobial properties against the test pathogens chosen for the study. T. asperellum indicated significantly greater bioactivity against all four bacterial pathogens and Candida albicans ATCC 10231 under study. The ranges of minimum inhibitory concentrations (MICs) of the fungi depicting antimicrobial properties were determined. The results obtained suggest that F. equiseti, P. medicaginis, T. asperellum, and T. virens of M. cordata harness bioprospective values as natural drug candidates. This is the first report on isolation and evaluation of the antimicrobial properties of endophytic and rhizosphere fungi of Mikania cordata.

Background and aim: The Cameroonian flora abounds in plants with multidimensional therapeutic virtues which can play an important role in the fight against resistance to antibiotics and the search for new antimicrobials. This study aimed to screen the antimicrobial potential of aqueous and ethanolic extracts of thirteen (13) samples (Bark, leaf, seed) of eight (8) plants from Cameroon against 3 reference pathogens and to evaluate their synergy with conventional antibiotics against eleven (11) multiresistant uropathogenic (MRU) bacteria. Method: Bioactive compounds were extracted from leaves of Leucanthemum vulgare, Cymbopogon citratus (DC.) Stapf, Moringa oleifera Lam and Vernonia amygdalina Delile; barks of Cinchona officinalis and Enantia chlorantha Oliv; barks and seeds of Garcinia lucida Vesque and leaves and seeds of Azadirachta indica (Neem) using distilled water and ethanol as solvents. The extracts were tested against Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 6538 and Candida albicans 10231 using the well diffusion method and the microdilution method. The synergistic effect was assessed (using disc diffusion method and the checkerboard method) against MRU bacteria namely Achromobacter xylosoxidans 4892, Citrobacter freundii 426, Enterococcus avium 1669, Escherichia coli 1449, Klebsiella oxytoca 3003, Kocuria rizophilia. 1542, Moraxella catarrhalis 4222, Morganella morganii 1543, Pseudomonas aeruginosa 3057, Staphylococcus aureus 1449 and Streptococcus agalactiae 3984. Results: We found that distilled water extracted a more important mass of phytochemical compounds (7.9-21.2%) compared to ethanol (5.8-12.4%). Except C. officinalis and G. lucida leaves, the rest of extracts were active with inhibition diameters (ID) ranging from 5 to 36 mm. Both ethanolic (EE) and aqueous extract (AE) of E. chloranta bark (ECB) were the most active against all pathogens with the mean ID of 17 and 36 mm vs S. aureus ATCC 6538, 23 and 14 mm vs E. coli ATCC 25922 and 36 and 19 mm vs C. albicans ATCC 10231. Only the EE of E. chloranta bark (ECB) had a strong activity against all the microorganisms tested (MIC <2 mg / ml); L. vulgare leaves (LVL) and G. lucida seed (GLS) had moderate (average MIC of 8 mg/ml) while all other extracts showed very weak antimicrobial activity. In addition, the fractional inhibitory concentration (FIC) ranged from 0.125 to 0.750. No antagonism (FIC> 4) or indifference (1≤ FIC≤4) was noted between the extracts and the antibiotics, but the best synergies were found with ECB which well-modulated Kanamycin (FIC = 0.125 against S. aureus and 0.250 against E. coli), nitrofurantoin (FIC = 0.250 against S. aureus and 0.188 against E. coli) and ampicillin (FIC = 0.125 against E. coli). Similarly, compared to other extracts, ECB, LVL and GLS also well-modulated ampicillin, ceftazidime, tetracycline, nitrofurantoin, and trimethoprim against all the above-mentioned resistant uropathogenic bacteria with important increase in fold area (IFA). Conclusion: This study show that E. chlorantha bark, L. vulgare leaves G. lucida seed, have good antimicrobial activity against both bacteria (Gram positive and Gram negative) and fungi (C. albicans); and should be more investigated for their possible use to the fight against MDR and MRU microorganisms.
