A Listeria monocytogenes Mutant Defective in Bacteriophage Attachment Is Attenuated in Orally Inoculated Mice and Impaired in Enterocyte Intracellular Growth

Spears, P. A., Suyemoto, M. M., Palermo, A. M., Horton, J. R., Hamrick, T. S., Havell, E. A., & Orndorff, P. E. (2008, June 17). Infection and Immunity.

By: P. Spears n, M. Suyemoto n, A. Palermo n, J. Horton n, T. Hamrick*, E. Havell n, P. Orndorff n

MeSH headings : Animals; Bacterial Adhesion; Bacteriophages / physiology; DNA Transposable Elements; DNA, Bacterial / chemistry; DNA, Bacterial / genetics; Enterocytes / microbiology; Female; Genetic Complementation Test; Glycosyltransferases / genetics; Listeria monocytogenes / pathogenicity; Listeria monocytogenes / virology; Listeriosis / microbiology; Liver / microbiology; Mice; Mice, Inbred A; Molecular Sequence Data; Mutagenesis, Insertional; Receptors, Virus / genetics; Sequence Analysis, DNA; Spleen / microbiology; Survival Analysis; Viral Plaque Assay; Virulence; Virulence Factors / genetics; Virus Attachment
topics (OpenAlex): Listeria monocytogenes in Food Safety; Salmonella and Campylobacter epidemiology; Microbial Inactivation Methods
TL;DR: Interestingly, the glcV lesion, while preventing phage attachment, did not alter the mutant's ability to bind to cultured mouse enterocyte monolayers, rather, the mutation appeared to alter a subsequent step in intracellular replication measured by a reduction in plaque-forming efficiency and plaque size.

2006 article

Host and bacterial factors in listeriosis pathogenesis

ORNDORFF, P., HAMRICK, T., SMOAK, I., & HAVELL, E. (2006, January 19). Veterinary Microbiology.

By: P. Orndorff n, T. Hamrick*, I. Smoak n & E. Havell n

author keywords: listeria; pathogenesis; pregnancy; predisposition; veterinary
MeSH headings : Animals; Cytosol / microbiology; Disease Susceptibility / microbiology; Environment; Female; Food Microbiology; Humans; Immunity, Cellular / immunology; Listeria / growth & development; Listeria / pathogenicity; Listeriosis / immunology; Listeriosis / microbiology; Listeriosis / transmission; Mice; Pregnancy; Pregnancy Complications, Infectious / immunology; Pregnancy Complications, Infectious / microbiology; Vacuoles / microbiology
topics (OpenAlex): Listeria monocytogenes in Food Safety; Salmonella and Campylobacter epidemiology; Viral gastroenteritis research and epidemiology
TL;DR: There are many features of the pathogenesis of listeriosis that have remained mysterious despite the extensive use of the microorganism in the study of cell-mediated immunity and intracellular growth, and Informational advances such as the sequence of the mouse and listerial genomes, and technical advancessuch as the discovery of listersia-susceptible mouse strains, may renew interest in the project.

Characterization of Escherichia coli Type 1 Pilus Mutants with Altered Binding Specificities

Harris, S. L., Spears, P. A., Havell, E. A., Hamrick, T. S., Horton, J. R., & Orndorff, P. E. (2001, July 1). Journal of Bacteriology.

By: S. Harris n, P. Spears n, E. Havell n, T. Hamrick n, J. Horton n & P. Orndorff n

MeSH headings : Adhesins, Bacterial / genetics; Adhesins, Bacterial / metabolism; Adhesins, Escherichia coli; Alleles; Chromosomes, Bacterial; Escherichia coli / physiology; Fimbriae Proteins; Fimbriae, Bacterial / genetics; Fimbriae, Bacterial / metabolism; Molecular Sequence Data; Mutation; Phenotype; Plasmids; Recombination, Genetic
topics (OpenAlex): RNA and protein synthesis mechanisms; Bacteriophages and microbial interactions; Bacterial Genetics and Biotechnology
TL;DR: PCR mutagenesis and a unique enrichment scheme were used to obtain two mutants, each with a single lesion in fimH, the chromosomal gene that encodes the adhesin protein (FimH) of Escherichia coli type 1 pili that were noteworthy in part because both were altered in the normal range of cell types bound by FimH.

MeSH headings : Adhesins, Bacterial / genetics; Adhesins, Escherichia coli; Animals; Bacterial Adhesion / genetics; Base Sequence; Chromosome Mapping; Erythrocytes / microbiology; Escherichia coli / genetics; Escherichia coli / pathogenicity; Fimbriae Proteins; Guinea Pigs; Hemagglutination Tests; Macrophages / microbiology; Mice; Molecular Sequence Data; Phenotype; Point Mutation
topics (OpenAlex): Escherichia coli research studies; Bacterial Genetics and Biotechnology; Transgenic Plants and Applications
TL;DR: Temperature shift experiments revealed that new FimH biosynthesis was required for the phenotypic change, and a temperature-sensitive (ts) fimH mutant that agglutinated guinea pig erythrocytes but not at 42 degrees C was chosen for further study. (via Semantic Scholar)

Host and Bacterial Factors Involved in the Innate Ability of Mouse Macrophages To Eliminate Internalized UnopsonizedEscherichia coli

Hamrick, T. S., Havell, E. A., Horton, J. R., & Orndorff, P. E. (2000, January 1). Infection and Immunity.
