What are antibacterial metabolites?
Antimicrobial peptides (AMPs) represent a defense system against invading pathogenic bacteria and are effective therapeutically against antibiotic-resistant bacteria by causing rapid killing. Nonribosomal peptides represent a large family of bioactive secondary metabolites produced by bacteria and fungi.
Which antibiotic is produced by Aspergillus?
From aspergillus filtrates Chain and his associates2 of the Sir William Dunn School of Pathology, Oxford University, subsequently isolated a crystalline antibiotic, “helvolic acid,” the name being derived from the variety of Aspergillus fumigatus yielding the best product.
What is Aspergillus spp?
Aspergillus species are filamentous fungi that are commonly found in soil, decaying vegetation, and seeds and grains, where they thrive as saprophytes. Aspergillus species can be occasionally harmful to humans [1-3].
Which antibiotic is most effective against Bacillus subtilis?
Antibiotics which appear especially useful in the treatment of Bacillus infections are clindamycin and vancomycin, to which the vast majority of strains are susceptible in vitro.
Is Aspergillus an antibiotic?
Aspergillus have proven to be a prolific source of secondary metabolites with interesting biological activities, including antibacterial activity (Perrone et al.
Is voriconazole an antibiotic?
Voriconazole, sold under the brand name Vfend among others, is an antifungal medication used to treat a number of fungal infections. This includes aspergillosis, candidiasis, coccidioidomycosis, histoplasmosis, penicilliosis, and infections by Scedosporium or Fusarium.
Is Aspergillus mold harmful?
Aspergillus lives in the environment For people with healthy immune systems, breathing in Aspergillus isn’t harmful. However, for people who have weakened immune systems, breathing in Aspergillus spores can cause an infection in the lungs or sinuses which can spread to other parts of the body.
What diseases can Bacillus subtilis cause?
Infections attributed to B. subtilis include bacteremia, endocarditis, pneumonia, and septicemia. However, these infections were found in patients in compromised immune states.
What disease does Bacillus megaterium cause?
megaterium was the culprit of the brain abscess. Importantly, when this bacterium is found in clinical laboratory specimens, it is often reported as “insignificant contaminant”. [4] However, this case report proves that chronic brain abscesses can be caused by B. megaterium….Table 1.
