Full‐length 16S and 18S rRNA Oxford Nanopore sequencing of large intestine contents from 30 healthy European brown hares revealed broad gut microbiome diversity. An 80% identity threshold detected substantially greater taxonomic richness than 95%, emphasizing the value of long‐read sequencing in wildlife microbiome research. ABSTRACT The European brown

Aggregatibacter actinomycetemcomitans Leukotoxin [PDF]
Aggregatibacter actinomycetemcomitans is a Gram-negative bacterium that colonizes the human oral cavity and is the causative agent for localized aggressive periodontitis (LAP), an aggressive form of periodontal disease that occurs in adolescents. A. actinomycetemcomitans secretes a protein toxin, leukotoxin (LtxA), which helps the bacterium evade the ...

Regulation of expression of the Pasteurella haemolytica leukotoxin determinant [PDF]
The Pasteurella haemolytica leukotoxin determinant is composed of four contiguous genes encoded on the same DNA strand and denoted lktCABD, in the order of their genetic organization. To gain a better understanding of the expression and regulation of the leukotoxin, the transcripts and promoters of the lkt determinant were mapped.
