2018 review

Heavy Metal Resistance Determinants of the Foodborne Pathogen Listeria monocytogenes

[Review of ]. GENES, 10(1).

By: C. Parsons n, S. Lee* & S. Kathariou n

author keywords: Listeria monocytogenes; heavy metal resistance; mobile genetic element; cadmium; arsenic
TL;DR: A review of the mechanisms associated with non-essential heavy metals such as arsenic and cadmium is lacking and a growing body of work indicates the association of these determinants with other cellular functions such as virulence, suggesting the importance of further study in this area.

2017 journal article

The Arsenic Resistance-Associated Listeria Genomic Island LGI2 Exhibits Sequence and Integration Site Diversity and a Propensity for Three Listeria monocytogenes Clones with Enhanced Virulence

APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 83(21).

By: S. Lee n, T. Ward *, D. Jima n, C. Parsons n & S. Kathariou n

author keywords: Listeria monocytogenes; arsenic resistance; genomic island; heavy metal resistance; hypervirulent clones
MeSH headings : Arsenic / metabolism; Bacterial Proteins / genetics; Bacterial Proteins / metabolism; Genetic Variation; Genomic Islands; Humans; Listeria monocytogenes / genetics; Listeria monocytogenes / metabolism; Listeria monocytogenes / pathogenicity; Listeriosis / microbiology; Virulence
TL;DR: Investigating 85 arsenic-resistant L. monocytogenes strains indicates that LGI2 has a propensity for certain serotype 4b clones, exhibits content diversity, and is highly promiscuous, suggesting an ability to mobilize various accessory genes into diverse chromosomal loci.

2014 journal article

Prevalence of Rickettsiales in ticks removed from the skin of outdoor workers in North Carolina

PARASITES & VECTORS, 7.

By: S. Lee n, M. Kakumanu n, L. Ponnusamy n , M. Vaughn*, S. Funkhouser*, H. Thornton n, S. Meshnick*, C. Apperson n

author keywords: Ticks; Rickettsiales pathogens; Rickettsia; Ehrlichia; Reverse line blot hybridization
MeSH headings : Animals; Arachnid Vectors / microbiology; Base Sequence; DNA, Bacterial / chemistry; DNA, Bacterial / genetics; DNA, Ribosomal / chemistry; DNA, Ribosomal / genetics; Double-Blind Method; Female; Humans; Ixodidae / microbiology; Male; Molecular Sequence Data; North Carolina / epidemiology; Polymerase Chain Reaction; Prevalence; Rickettsia / genetics; Rickettsia / isolation & purification; Rickettsia Infections / epidemiology; Rickettsia Infections / microbiology; Sequence Analysis, DNA; Tick Infestations / epidemiology
TL;DR: It is concluded that in North Carolina, the most common rickettsial exposure is to R. amblyommii carried by A. americanum, and Rickettsiales bacteria, including novel species of Rickettsia, were less frequently detected in A.Americanum. (via Semantic Scholar)

2013 journal article

Genetic Determinants for Cadmium and Arsenic Resistance among Listeria monocytogenes Serotype 4b Isolates from Sporadic Human Listeriosis Patients

APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 79(7), 2471–2476.

By: S. Lee n, M. Rakic-Martinez n, L. Graves*, T. Ward *, R. Siletzky n & S. Kathariou n

MeSH headings : Arsenic / toxicity; Cadmium / toxicity; Drug Resistance, Bacterial; Genes, Bacterial; Humans; Listeria monocytogenes / drug effects; Listeria monocytogenes / genetics; Listeria monocytogenes / isolation & purification; Listeriosis / microbiology
TL;DR: In Listeria monocytogenes serotype 4b isolates from sporadic listeriosis, heavy metal resistance was primarily encountered in certain clonal groups (ECI, ECII, and ECIa); all arsenic-resistant isolates harbored the arsenic resistance cassette previously identified in pLI100.

2012 journal article

Two Novel Type II Restriction-Modification Systems Occupying Genomically Equivalent Locations on the Chromosomes of Listeria monocytogenes Strains

APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 78(8), 2623–2630.

By: S. Lee n, T. Ward *, R. Siletzky n & S. Kathariou n

MeSH headings : Bacteriophages / growth & development; Chromosomes, Bacterial; Cluster Analysis; DNA Restriction-Modification Enzymes / genetics; DNA, Bacterial / chemistry; DNA, Bacterial / genetics; DNA, Bacterial / metabolism; Electrophoresis, Gel, Pulsed-Field; Listeria monocytogenes / classification; Listeria monocytogenes / enzymology; Listeria monocytogenes / genetics; Listeria monocytogenes / virology; Molecular Sequence Data; Molecular Typing; Sequence Analysis, DNA; Synteny
TL;DR: Among the sequenced Listeria phages, lytic phages possessed significantly fewer recognition sites for these RM systems than lysogenic phage sequence content, suggesting that in lyticphages sequence content evolved toward reduced susceptibility to such RM systems. (via Semantic Scholar)
