Understanding of bacterial virulence using the silkworm infection model.
نویسنده
چکیده
We have used silkworms, larva of Bombyx mori, to investigate host-pathogen interactions. Silkworms have several advantages, such as high availability of a large number of animals and ease of injection of quantitative amounts of samples. Human pathogenic bacteria such as Staphylococcus aureus, Streptococcus pyogenes, or Pseudomonas aeruginosa kill silkworms. In this review, I would like to summarize our approach identifying S. aureus virulence factors by using the silkworm infection model.

Utilization of a silkworm model for understanding host-pathogen interactions
Studies of the interactions between humans and pathogenic microorganisms require adequate representative animal infection models. Further, the availability of invertebrate models overcomes the ethical and financial issues of studying vertebrate materials. Insects have an innate immune system that is conserved in mammals. The recent utilization of silkworms as an animal infection model led to th...
متن کاملIdentification of the putative protein phosphatase gene PTC1 as a virulence-related gene using a silkworm model of Candida albicans infection.
Protein phosphatases are critical for the regulation of many cellular processes. Null mutants of 21 putative protein phosphatases of Candida albicans were constructed by consecutive allele replacement using the URA3 and ARG4 marker genes. A simple silkworm model of C. albicans infection was used to screen the panel of mutants. Four null mutant (cmp1Delta, yvh1Delta, sit4Delta, and ptc1Delta) st...
متن کاملIdentification of lysocin E using a silkworm model of bacterial infection.
New antimicrobials with novel mechanisms need to be developed to combat antimicrobial-resistant pathogenic bacteria. The current authors recently reported discovery of a new antibiotic named "Lysocin E". Lysocin E was identified using a silkworm model of bacterial infection. The current review discusses the advantages of using a silkworm model of bacterial infection to identify and develop ther...
متن کاملA silkworm model of pathogenic bacterial infection.
Silkworms are invertebrate animals that are killed by bacteria pathogenic against humans, such as Staphylococcus aureus, Streptococcus pyogenes, Pseudomonas aeruginosa, and Vibrio cholerae. Injection into the hemolymph of antibiotics that are clinically used for human patients abolishes the killing effects. There are several advantages to using silkworms as an infection model, such as low cost,...
متن کاملEffect of Vitamin A on Listeria monocytogenes Infection in a Silkworm Model
Insect infection models have been used increasingly to study various pathogenic agents in evaluations of pathogenicity and drug efficacy. In this study, we demonstrated that larvae of the silkworm Bombyx mori are useful for studying Listeria monocytogenes infections in insects. Infection with the L. monocytogenes wild-type strain induced silkworm death. Infection by a listeriolysin O (LLO) dele...
