Background: gram-negative bacteria-salmonella typhi and gram-positive bacteria-staphylococcus aureus are types of bacteria that cause infectious disease among several areas in Indonesia. Staphylococcus aureus often found in skin lesions injury. Red ginger extract (Zingiber officinale var rubrum) has been known for its medicinal value especially as an antibacterial agent. Purpose: This study aims to test the ability of Zingiber officinale var rubrum on inhibiting the growth of Staphylococcus aureus. Methods: the activity of the antibacterial agent was calculated based on Minimum Inhibitory Concentration (MIC) using dilution method. Minimum Inhibitory Concentration of extract was determined by incubating bacteria with the extract overnight at 37 0C. Changes in turbidity and inhibition on bacterial growth were then observed. Result: The results show that minimum concentration for inhibitory effect was 1000 μg/mL.Conclusion: extract of Zingiber officinale var rubrum have an inhibitory effect on the growth of Staphylococcus aureus but no activity of killing bacterial was observed on the concentration given.

Moniliophthora Roreri

Theobroma cacao is the main raw material to produce chocolate, as well as for use in the food, cosmetic, and pharmaceutical industries. However, Moniliophthora roreri is one of the most destructive fungal diseases and the main limiting of cacao production worldwide. Thus, this work aimed to assess the inhibitory effect of extracts of Zingiber officinale (T1) and Aloe vera (T2), and Trichoderma harzianum + Bacillus subtillis. (T3) on Moniliophthora roreri infection in Theobroma cacao; in addition, a control (T4) was also evaluated. Each treatment was applied to six plants of cacao. Incidence of monilia infection and fruit weight were monitored every 15 days (in total four periods) after the application of the treatment by spray. Significant differences (P<0.05) were found among treatments for incidence. It was observed that spraying entire cacao trees after two times (approximately 30 days) showed a reduction of monilia infection. After all periods, T1, T2, and T3 showed an incidence of monilia infection by 20.5, 17.7, and 14.9% respectively, compared to cultural control of 41.1%. This reduction of moniliasis infection translates into an increase in fruit weight average for T3 (8.4 kg), T2 (7.3 kg), and T1 (6.9 kg). In contrast, in the control (T3), the fruit weight average decreased by 5.3 kg. Biological control showed efficient management of pathogens as M. roreri. It is recommended to use such antifungal (Aloe vera) spray over at least 120 days which would decrease infection incidence even more.

The objective of this study was to evaluate antifungal activity and resistance inducing potential of crude extracts derived from neem (Azadirachta indica) and ginger (Zingiber officinale) against three isolates of Sclerotinia sclerotiorum, the causal agent of mustard white mold under in vitro and in vivo conditions. In addition, enzymatic tests were carried out to assess the effect of crude extracts on activities of resistance-inducing enzymes in mustard leaves. The results showed that ethanol extracts of neem and ginger at concentration 2 g/l were able to reduce mycelial growth of the pathogen (isolate 3) by 61.5 and 44.3%, respectively. The ethanol extracts of neem and ginger at concentration 2 g/l reduced infection radius on plant leaves from 9.7 in control to 3.1 and 3.4, respectively, due to antifungal efficacy. In addition, ethanol extracts of neem and ginger at concentration 2 g/l decreased infection radius (isolate 1) on plant leaves from 9.5 in control to 2.1 and 2.3, respectively, seven days after application. Enzymatic analyses showed significant increase in level of chitinases, β-1,3-glucanase, Phenylalanine ammonia lyase and Peroxidase due to application of ethanol extracts of neem and ginger.

Present study was carried out to investigate the inhibition effect of extracts of some aquatic and aromatic plants on three fungi genera (Aspergillus, Penicillium and Saprolegnia) infecting common carp and its eggs. The inhibition test was done for 15 species of plants represented: Hornwort Ceratophyllum demersum L.; Water hyssop Bacopamonnieria (L.) Hayata et Mastum; Eurasian watermilfoil Myriophyllum spicatumL.; curled pondweed Potamogeton crispus L.; Widgeon-grass Ruppia maritimaL.; Mint Mentha spicata L.; Ginger Zingiber officinale Roscoe; Onion Allium cepa L.; Leek Allium ampeloprasum L. var. porrum (L.) ;Damas Conocarpus lancifolius Engl. & Diels; Garden cress Lepidium sativum L.; Brant's oak Quercus brantii Lindl. and Eggplant Solanum melongena L. using the manner of food poisoning in Petri dishes. The results showed a difference in the inhibitory effect of the extracts according to the species of plants and fungi. The highest percentage of inhibition on Aspergillus was by using Q. brantii (79%) and the lowest was the R. maritime (18%). The highest percentage of inhibition on Penicillium was obtained by using the water extract of Z. officinale (81%) and lowest was the S. melongena (2%). M. spicatum extract has the highest inhibitory effect on Saprolegnia (100%) while the lowest was A. sativum (38.8%).

This study evaluates the antibacterial effects of Zingiber officinale essential oil and Orthosiphon stamineus water extract against Enterococcus faecalis. The herbs were prepared in various concentrations to determine their minimum inhibitory concentrations (MIC) and growth inhibitory effect. Anti-adhesion activities of the herbs were determined by co-incubation with E. faecalis cultures for 6 and 24 h. Biofilm disruption activities were determined by adding the studied herbs into preformed E. faecalis biofilm. The effects on the morphology of E. faecalis grown as biofilm were studied using scanning electron microscopy (SEM). The MICs of ginger oil and O. stamineus extract were 0.31 and 25 mg/mL, respectively. Between the tested herbs, ginger exhibited greater inhibitory effects on the growth of E. faecalis grown in suspension mode. Both herbs generally showed anti-adhesion activities in inverse concentration-dependent manner. No significant biofilm disruption activities by both herbs were observed. SEM analyses showed E. faecalis cell surface changes in the treated biofilm. The studied herbs may have compromised the integrity of the bacterial cell membrane. These findings suggest that the studied herbs may have better antibacterial activities against E. faecalis in suspension mode compared to biofilm mode, with ginger oil showed greater antibacterial activity compared to O. stamineus extract.
