Proc Natl Acad Sci U S A
. 2024 Jan;
121(2):e2316540120.
PMID: 38170751
How the microaerobic pathogen establishes its niche and expands in the gut lumen during infection is poorly understood. Using 6-wk-old ferrets as a natural disease model, we examined this aspect...

. 2023 Oct;
PMID: 37873437
Significance: There is a gap in knowledge about the mechanisms by which populations expand during infection. Using an animal model which accurately reflects human infection without the need to alter...

Sci Adv
. 2023 Aug;
9(32):eade2693.
PMID: 37566649
Histone modifications control numerous processes in eukaryotes, including inflammation. Some bacterial pathogens alter the activity or expression of host-derived factors, including sirtuins, to modify histones and induce responses that promote...

J Leukoc Biol
. 2022 Jul;
112(6):1457-1470.
PMID: 35866361
The discovery of neutrophil subtypes has expanded what is known about neutrophil functions, yet there is still much to learn about the role of these subtypes during bacterial infection. We...

Callahan S, Johnson J
Curr Protoc
. 2021 Dec;
1(12):e293.
PMID: 34875141
Nucleases are ubiquitous in pathogens and allow bacteria to acquire nucleotide nutrients, take up foreign DNA, induce tissue damage, degrade neutrophil extracellular traps, and modulate the host inflammatory response. Furthermore,...

Curr Protoc
. 2021 Nov;
1(11):e294.
PMID: 34807525
Campylobacter jejuni is the leading cause of bacterial-derived gastroenteritis worldwide, infecting 96 million individuals annually. During infection, inflammation and tissue pathology occur in the lower gastrointestinal tract, including the recruitment...

PMID: 34031129
Campylobacter spp. are the leading cause of bacterium-derived gastroenteritis worldwide, impacting 96 million individuals annually. Unlike other bacterial pathogens of the gastrointestinal tract, Campylobacter spp. lack many of the classical...

203(15):e0016421.
PMID: 34001558
A previously identified transcriptional regulator in Campylobacter jejuni, termed HeuR, was found to positively regulate heme utilization. Additionally, transcriptomic work demonstrated that the putative operons CJJ81176_1390 to CJJ81176_1394 (CJJ81176_1390-1394) and...
