serial passages การใช้

• The process of serial passage yields a live vaccine.
• His work prior to rabies involved virus attenuation, but not through serial passage.
• The researchers performed serial passage on two strains of H5N1 that are quite pathogenic to quail.
• Several serial passage experiments have been conducted to determine the feasibility of the virus becoming transmissible in humans.
• In particular, Ron Fouchier and his colleagues did a 10-step serial passage experiment in ferrets.
• Identifying and studying mutations that occur through serial passage often reveals information about the virus or bacterium being studied.
• Serial passage is an artificial technique that is used in a laboratory setting, rather than a natural process.
• Das Gupta maintained the " Plasmodium " species by serial passage in monkeys until Knowles returned from leave.
• One advantage that was quickly apparent was that staphylococci did not develop significant resistance, despite serial passage in culture media containing vancomycin.
• In particular, serial passage can be quite useful in experiments that seek to change the virulence of a virus or other pathogen.
• Then, he realized that he could put dog tissue into a monkey to infect it and then perform serial passage in monkeys.
• For example, one study used serial passage in baboons to create a strain of HIV-2 that is particularly virulent to baboons.
• This suggests that both HIV-1 and HIV-2 are adapted to humans, and serial passage could have been the process responsible for it.
• One consequence of this is that serial passage is useful in creating vaccines, since scientists can apply serial passage and create a strain of virus that has low virulence.
• One consequence of this is that serial passage is useful in creating vaccines, since scientists can apply serial passage and create a strain of virus that has low virulence.
• Alternatively, serial passage can be used to help determine whether a species could act as an intermediate host species and help a pathogen jump from one species to another.
• In particular, he took brain tissue from an infected dog and transplanted it into another dog, repeating this process multiple times, and thus performing serial passage in dogs.
• It is easy to select for reduced membrane permeability to chloramphenicol " in vitro " by serial passage of bacteria, and this is the most common mechanism of low-level chloramphenicol resistance.
• Similar to the serial passages in his own third symphony and his admiration of Ives The Unanswered Question, Bernstein s lauding of these works stems not from the use of atonality, but the presence of tonality.
• Vaccines that only contain attenuated vaccinia viruses ( an attenuated virus is one in which the pathogenicity has been decreased through serial passage ) have been proposed, but some researchers have questioned the possible effectiveness of such a vaccine.
