The Ferrier Lecture is a Royal Society lectureship given every three years "on a subject related to the advancement of natural knowledge on the structure and function of the nervous system". [1] It was created in 1928 to honour the memory of Sir David Ferrier , a neurologist who was the first British scientist to electronically stimulate the ...
Bacteria are not able to grow around antibiotics to which they are sensitive. This is called "the zone of inhibition". Antibiotic sensitivity testing or antibiotic susceptibility testing is the measurement of the susceptibility of bacteria to antibiotics. It is used because bacteria may have resistance to some antibiotics.
The first CDI system to be discovered was a Type V secretion system, encoded by the cdiBAI gene cluster found widespread throughout pathogenic Gram-negative bacteria. The first protein encoded in the operon, CdiB, is an outer membrane beta-barrel protein that exports CdiA, presenting it on the cell surface of a CDI-expressing (CDI+) bacterium.
Agar diffusion was first used by Martinus Beijerinck in 1889 to study the effect of auxins on bacterial growth. However, the method has been developed, refined and standardized by many scientists and scientific organizations over the years including George F. Reddish, Norman Heatley, James G. Vincent, [8] Alfred W. Bauer, William M.M. Kirby, John C. Sherris, [4] [5] Hans Martin Ericsson, the ...
In his 50-year career, Ferrier published 180 papers, reviews and books, and gave 10 invited plenary lectures at international symposia. [15] His reviews were of particular benefit to the chemical community but perhaps of most value was the book "Monosaccharide Chemistry, [ 16 ] written with Dr Peter Collins in 1972 and majorly updated as ...
Bacteria in the culture on the right are resistant to most of the antibiotics. In addition to drugs being specific to a certain kind of organism (bacteria, fungi, etc.), some drugs are specific to a certain genus or species of organism, and will not work on other organisms. Because of this specificity, medical microbiologists must consider the ...
Sir David Ferrier FRS (13 January 1843 – 19 March 1928) was a pioneering Scottish neurologist and psychologist. Ferrier conducted experiments on the brains of animals such as monkeys and in 1881 became the first scientist to be prosecuted under the Cruelty to Animals Act, 1876 which had been enacted following a major public debate over ...
Those that target the bacterial cell wall (penicillins and cephalosporins) or the cell membrane , or interfere with essential bacterial enzymes (rifamycins, lipiarmycins, quinolones, and sulfonamides) have bactericidal activities, killing the bacteria. Protein synthesis inhibitors (macrolides, lincosamides, and tetracyclines) are usually ...
