Ferrichrome is a representative member of a group of microbial products which show very intense growth factor activity when tested with a small number of selected fungal and bacterial species (1). Some of the members of this group of compounds, e.g. aspergillic acid (2), nocardamin (3), and grisein (albomycin) (4), are potent antibiotics against certain strains of microorganisms. Although the u...

Adhesion and subsequent growth of microorganisms on material surfaces are a major concern in many biomedical applications. Currently, various polymers are immobilized on material surfaces to prevent microbial colonization. However, there are several challenges with regard to the coating materials, including their inability to kill microorganisms, complexity of surface grafting, limited durabili...

Microbial lifeforms associated with land plants represent a rich source for crop growth- and health-promoting microorganisms and biocontrol agents. Volatile organic compounds (VOCs) produced by the plant microbiota have been demonstrated to elicit plant defenses and inhibit the growth and development of numerous plant pathogens. Therefore, these molecules are prospective alternatives to synthet...

This study investigated a new method for delivering microbial mosquito control agents into aquatic sites as ice granules for mosquito control. Solutions containing powder formulations of Bacillus thuringiensis israelensis (Bti) or Bacillus sphaericus were transformed into ice pellets (named IcyPearls) using a special ice-making machine. This new technique was demonstrated to have the following ...

Antimicrobial characteristics of metals reveal that Ag despite its economic constraints remains the most popular antibiotic agent. Antimicrobial characteristics of copper nanoparticles (CNPs) are not well understood. To our knowledge, no systematic comparative study on microbial properties of silver nanoparticles (SNPs) and CNPs exists. In this article, a comparative study on microbial properti...

The MAGPIE system has been designed and implemented to address the data management and analysis problems that arise during the interpretation of whole microbial genomes. The system consists of a command-driven query-answering interface and two cooperating daemons: (1) an active rule daemon that builds and maintains a knowledge base for a particular genome and (2) an annotated logic programming ...

We report herein a 41-year-old female with a tubo-ovarian abscess (TOA), which microbial cultures showed to contain extended-spectrum beta-lactamase (ESBL)-producing E. coli, a causative agent of community-acquired infection. The patient initially presented with acute abdominal pain and back pain. Pelvic computed tomography and transvaginal ultrasonography revealed multiple cystic lesions in th...

New strategies to treat antibiotic-resistant infections are urgently needed. We serendipitously discovered that stem cell conditioned media possessed broad antimicrobial properties. Biochemical, functional, and genetic assays confirmed that the antimicrobial effect was mediated by supra-physiological concentrations of transferrin. Human transferrin inhibited growth of gram-positive (Staphylococ...

Present study deals with Topical Drug Delivery system composed of polyherbals including Neem, Tulsi, Aloe and Fenugreek which are having Antifungal and Antibacterial activity in the form of gel, were formulated using gelling agent as Carbopol 934 and was compared with ointment prepared by taking same herbal drugs using emulsifying ointment base B. P. The gels and ointments were evaluated for va...

as the host plants based on their physical and chemical characteristics can affect virulence of microbial control agents on the target pest and its natural enemies, therefore in the current study, the virulence of beauveria bassiana tv isolate at concentration 107 conidia/ml was evaluated against t. urticae female adults, on three different host plants; tomato, cucumber and strawberry. spray to...
