The natural history of antibiotics
sensory systems are weighted and at which stage the combination takes place is still under investigation. But it seems that, at least in the fly, such integration occurs quite early on in the visuo-motor pathways, which helps the animal to keep its gaze level and remain stable in the air during rapid movements but also when slowly drifting. What is the point in studying the ocelli and other ins...
متن کاملAntimicrobial preservative effectiveness of natural peptide antibiotics.
The constantly growing resistance of microbes to drugs and other substances which fight microbial infections leads to search for new antimicrobial substances. Among substances which attract the scientists attention are antimicrobial peptides. Such compounds are quite common in nature and belong to the most important elements of the innate immune system of all living organisms. Numerous antimicr...
متن کاملDefensins. Natural peptide antibiotics of human neutrophils.
We extracted a granule-rich sediment from normal human neutrophils and subjected it to chromatographic, electrophoretic, and functional analysis. The extract contained three small (molecular weight less than 3,500) antibiotic peptides that were named human neutrophil peptide (HNP)-1, HNP-2, and HNP-3, and which will be referred to as "defensins." HNP 1-3, a mixture of the three defensins, kille...
متن کاملNatural immunization against malaria: causal prophylaxis with antibiotics.
Malaria remains the most prevalent vector-borne infectious disease and has the highest rates of fatality. Current antimalarial drug strategies cure malaria or prevent infections but lack a sustained public health impact because they fail to expedite the acquisition of protective immunity. We show that antibiotic administration during transmission of the parasite Plasmodium berghei results in sw...
متن کاملNatural Peptide antibiotics from tunicates: structures, functions and potential uses.
Because tunicates rely on innate immunity, their hemocytes are important contributors to host defense. Styela clava, a solitary ascidian, have eight hemocyte subtypes. Extracts of their total hemocyte population contained multiple small (2-4 kDa) antimicrobial peptides. When purified, these fell into two distinct families that were named styelins and clavanins.Styelins A-E are phenylalanine-ric...
