Lipopolysaccharide Complexes withPasteurella haemolyticaLeukotoxin [PDF]
Infection and Immunity, 1999 ABSTRACTThe presence of lipopolysaccharide (LPS) in gram-negative bacterial repeats-in-toxin (RTX) toxin preparations, as well as the harsh conditions required to remove it, suggests that LPS may complex with RTX toxins. Concentrated culture supernatant (CCS) preparations of the RTX toxinPasteurella haemolyticaleukotoxin (LKT) contained LKT and LPS as ...

Evolution of the leukotoxin promoter in genus
BMC Evolutionary Biology, 2009 Background The Mannheimia species encompass a wide variety of bacterial lifestyles, including opportunistic pathogens and commensals of the ruminant respiratory tract, commensals of the ovine rumen, and pathogens of the ruminant integument.

Nucleotide sequence of the leukotoxin gene from Actinobacillus actinomycetemcomitans: homology to the alpha-hemolysin/leukotoxin gene family [PDF]
Infection and Immunity, 1990 The leukotoxin produced by Actinobacillus actinomycetemcomitans has been implicated in the etiology of localized juvenile periodontitis. To initiate a genetic analysis into the role of this protein in disease, we have cloned its gene, lktA. We now present the complete nucleotide sequence of the lktA gene from A. actinomycetemcomitans.

The Microbial Aetiology of Periodontal Diseases [PDF]
, 2012 Introduction: The study of the aetiology of periodontal diseases has continued for decades with much progress shown in the last two decades. Having moved through periods of “whole” plaque (with emphasis on mass) being attributed to the disease process,

Aggregatibacter actinomycetemcomitans Leukotoxin [PDF]
Journal of Dental Research, 2010 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 ...

Receptor-Based Peptides for Inhibition of Leukotoxin Activity [PDF]
ACS Infectious Diseases, 2018 The Gram-negative bacterium Aggregatibacter actinomycetemcomitans, commonly associated with localized aggressive periodontitis (LAP), secretes an RTX (repeats-in-toxin) protein leukotoxin (LtxA) that targets human white blood cells, an interaction that is driven by its recognition of the lymphocyte function-associated antigen-1 (LFA-1) integrin.

Pathogens, 2022 Aggregatibacter actinomycetemcomitans is strongly associated with severe periodontitis, possibly due to its production of a potent leukotoxin. A genetic variant, the JP2 genotype, was found to produce more leukotoxin than the wild type because of a ...

IL-1R and inflammasomes mediate early pulmonary protective mechanisms in respiratory brucella abortus infection [PDF]
, 2016 Brucella spp. infection is frequently acquired through contaminated aerosols. The role of interleukin-1 beta (IL-1β) in the early pulmonary response to respiratory Brucella infection is unknown.
