“…El-Shenawy et al [ 22 ] results on isolation of essential oils from rosemary concurred with the ones obtained in this study ( Table 3 ). This may be attributed to the variety from which the essential oils were extracted from being the same.…”

Growth of fruits which form an important part of human diet has been jeopardized by the many fungal diseases that are present today. This study was conceived to isolate the most common fungal pathogens in passion fruits. Fungi were isolated using potato dextrose agar in addition to characterization using morphological, cultural, and biochemical means. Extraction of essential oils from rosemary (Rosmarinus officinalis) and eucalyptus (Eucalyptus agglomerata) was done. Before carrying the sensitivity test of essential oils to the fungal isolates, constituents of the essential oils were determined. The most common fungal pathogens isolated from passion fruits were Alternaria spp. (45%), Fusarium spp. (22%), Colletotrichum spp. (17%), and Penicillium spp. (16%). There was a relationship between heating time and yield of essential oils in rosemary (r = 0.99) and eucalyptus (r = 0.99). Conversely, there was no significant difference in the amount of essential oils produced by rosemary and eucalyptus (P = 0.08). Furthermore, there was a significant difference in growth inhibition of the fungal pathogens between essential oils from rosemary and eucalyptus (P = 0.000438). Fungal pathogens isolated from passion fruits can be controlled using essential oils from rosemary and eucalyptus. The oils need to be produced in large scale.

“…It has also been reported in the same study that essential oils of marjoram contains alcoholic terpenoids which gives it potent antagonistic nature against food borne microbes (Shenawy et al, 2015). Antagonist effect of Origanum majorana L. (marjoram) essential oil has been reported against cultures of Salmonella spp., Shigella, Proteus, E. coli, Citrobacter and Pseudomonas species isolated from poultry meat.…”

Origanum majorana L. is an important member of Lamiaceae family. It is native to Cyperus though it is largely found in Himalayan mountain range. It is well known for its traditional use as a medicinal herb to treat gastrointestinal, sleep and nervous system related issues. In the recent era, the use of synthetic antimicrobial agents for food safety has been questioned as consumers all over the world want to develop alternatives to antimicrobial treatments based on natural ingredients. This article compiles and justifies use of Origanum majorana L. as a potent preservative in food industry.

“…That said, in Egypt, a study by El-Shenawy et al . [81], rather revealed an antibacterial activity of Coriander EO (IZ=20 mm) greater than that we have found, and this contradictory result can be explained by the use of different bacterial strains of E. coli , different methods for MIC determination [82], the composition of EO, functional groups present in active component and their synergistic interactions, varietal differences, the test method used as well as culture conditions (type and volume of broth, temperature, time of incubation, concentration, and age of inoculums) [83-85].…”

Aim:The aim of this study is to investigate, in vitro, a possible antibacterial activity of Algerian essential oils (EOs) of Thyme (Thymus vulgaris L.) and that of Coriander (Coriandrum sativum L.) against multidrug-resistant avian Escherichia coli strains and this in a perspective of their future use as a substitute for antibiotics (ATBs).Materials and Methods:In addition to the reference strain of E. coli ATCC 25922, 40 strains of avian E. coli have been isolated (24 strains of broilers and 16 of turkeys), their antimicrobial resistance profile was determined by antibiogram tests against 21 ATBs whereupon they were subjected to the action of two Algerian EOs; the EO of Thyme (T. vulgaris L.) and that of Coriander (C. sativum L.), which oils were extracted by hydrodistillation and analyzed by Gas Chromatography coupled to Mass Spectrometry (GC-MS) and this for the determination of their chemical composition. The antibacterial activity, resulting in zones of inhibition, was evaluated by carrying out, in triplicate, aromatograms for both pure EO and that which has been diluted to 15% in Dimethyl Sulfoxide (DMSO), while the minimum inhibitory concentrations (MIC) of the two EOs were highlighted by the method of liquid macrodilution.Results:Antibiogram performance demonstrated an alarming state of antimicrobial resistance, the multidrug resistance rate was estimated at 100% for the broilers chicken strains and at 81.25% for strains isolated from turkeys, hydrodistillation allowed to obtained EOs with yields estimated at 1.22±0.26% for Thyme EO and 0.23±0.15% for the essence of Coriander, the GC-MS analysis identified 19 main compounds and showed that the majority chemical components were Carvacrol (73.03%) for Thyme volatile oil and Linalool (60.91%) for Coriander EO, aromatograms and the determination of MIC concluded that the EO of Thyme showed a greater antibacterial activity with an average of the zones of inhibition estimated at 26.75±0.426 mm and MIC ranging from 0.07 to 0.93 mg/ml against an average of the inhibition zones evaluated at 17.05±0.383 mm and MICs evaluated between 0.6 and 10 mg/ml for the EO of Coriander.Conclusion:In aviculture, these results seem to be very promising in the case where we think about the replacement of ATBs by EOs, in vivo studies would be very interesting to confirm or invalidate this hypothesis.
