As part of the ongoing search for novel anti microbial agents and their use in singular or combined drug therapy, a polypeptide fractions of Mr about 14.500 and 15.00 KDa were isolated from the lymph fluid of two groups of intact and immunized Saudi Arabian honeybees (Apis mellifera) obtained from Al-Qasim and Hail locations around Riyadh during the honey season 2008 following experimental infection with 1.1 x l0 6 viable Escherichia coli cells (ATCC 25922). The polypeptide was purified to… 
Investigation and comparison of antibacterial activity of four types of natural honey found in Duhok city, Iraq with commercial one against a multi-resistant Staphylococcus aureus strains isolated from wounds and burns infections highlights that some natural D Uhokian honey has complete and partial antibacterial activities.
Antimicrobial Activity of Different Saudi Arabia Honeys
Investigation of honey samples from 12 different floral sources indicated that samples with different Saudi honeys were effective antibacterial agents against tested pathogenic bacteria as they inhibited their growth when honey was added to their growing cultures.
In vitro antimicrobial activities of Saudi honeys originating from Ziziphus spina‐christi L. and Acacia gerrardii Benth. trees
The findings indicate the antimicrobial potential of Saudi honeys to be considered in honey standards, and their therapeutic use as medical‐grade honeys needs further investigations.
Potential antibacterial activity of some Saudi Arabia honey
It could be concluded that the Saudi honey inhibit the growth of bacterial strains and that honey can be used as complementary antimicrobial agent against selected pathogenic bacteria.
Antibacterial and Antioxidant Activities of Some Saudi Arabia Honey Products
It was concluded that Saudi Arabia honey products have the capacity to suppress the growth of pathogenic bacteria and perform significant radical scavenging activities.
Isolation and identification of bacteria causing mastitis in small ruminants and their susceptibility to antibiotics, honey, essential oils, and plant extracts
This study proved that Egyptian honey, onion, and black cumin essential oils have a marked strong antibacterial effect against bacteria isolated from small ruminant mastitis, but still further extensive studies are needed to discover the therapeutic properties of these plant extracts and honey.
The effect of diflubenzuron and hexaflumuron on the last larval instars of the Mediterranean Flour Moth Anagasta kuehniella (Zeller) (Lepidoptera: Pyralidae) under laboratory conditions
The results indicated that the percentage of transformation of larvae to pupae, larvae to adult and pupae to adults reduced with increase in dosage, which indicates that IGRs play an effective role in inhibiting cuticle formation and can reduce pest population.


A Survey of the Antibacterial Activity of Some New Zealand Honeys
The high antibacterial activity of manuka honey was in many cases due entirely to this non‐peroxide component.
Investigation of in vitro antimicrobial activity of honey.
The findings indicate that honey samples with thyme, thyme + acorn, pine + carob, pine+ carob + anis and pine + chestnut are more effective than the other honey of floral sources.
Antimicrobial Potential of Honey on some Microbial Isolates
The study shows that honey, like antibiotics, has certain organisms sensitive to it while others are resistant, and the sensitivity varies depending on the source of the honey.
Bactericidal activity of different honeys against pathogenic bacteria.
Antibacterial Activity of Honey against Strains of Staphylococcus Aureus from Infected Wounds
The antibacterial action of honey in infected wounds does not depend wholly on its high osmolality, but the action of manuka honey stems partly from a phytochemical component, so this type of honey might be more effective in vivo.
Immunochemical screening for antimicrobial drug residues in commercial honey.
Experimental heating (40 degrees C) of honey spiked with sulfathiazole indicated that the sulfa drug(s) responsible for positive EIA results could be present a sugar derivatives.
Apidaecins: antibacterial peptides from honeybees.
The apidaecins represent a new family of inducible peptide antibiotics with the following basic structure: GNNRP(V/I)YIPQPRPPHPR(L/I).
Antimicrobial Peptide Evolution in the Asiatic Honey Bee Apis cerana
Comparison of these four antimicrobial peptide gene families with those of the Western honeybee revealed that there are many similarities in the quantity and amino acid components of peptides in the abaecin, defensin and apidaecin families, while many more hymenoptaecin peptides are found in the Asiatic honeybee than those in the Western bee.
