Evolution of the leukotoxin operon in genus Mannheimia

, 2005
The leukotoxin protein of Mannheimia haemolytica belongs to the HlyA-like subfamily of cytotoxic RTX (repeats in toxin) proteins. To test the hypothesis that different lineages of genus Mannheimia gained the leukotoxin operon via horizontal gene transfer

A role for divalent cations in the cytotoxicity of Pasteurella Haemolytica Leukotoxin

, 1987
Pasteurella haemolytica (Biotype A, serotype 1), the primary causative agent of bovine pneumonic pasteurellosis, produces a potent ruminant specific leukotoxin that is believed to be a primary virulence determinant.

Natural Therapeutic Agents’ Efficacy in Preventive Strategies against the Periodontal Pathogen Aggregatibacter actinomycetemcomitans: An In Vitro Study

Oral
Adolescent carriers of the Aggregatibacter actinomycetemcomitans JP2 genotype have an increased risk of developing periodontitis, due to the bacterium’s high leukotoxin (LtxA) production.

Characterization of Mannheimia (Pasteurella) haemolytica leukotoxin interaction with bovine alveolar macrophage $\beta$2 integrins

, 2005
Mannheimia (Pasteurella) haemolytica, the etiologic agent of bovine pneumonic mannheimiosis, produces an exotoxic leukotoxin. The leukotoxin (LktA) is a member of the RTX (repeats in toxin) family of bacterial cytolysins and is distinguished from other ...

Pasteurella haemolytica Leukotoxin and Its Interaction With Target Cells [PDF]

, 1995
A number of Pasteurella haemolytica isolates from cattle and sheep, including representatives of all serotypes and untypables, was examined for leukotoxin (LktA) production at the end of the log phase of growth in brain-heart infusion broth. The bacteria

Inflammatory cell death of human macrophages induced by Aggregatibacter actinomycetemcomitans leukotoxin [Elektronisk resurs]

, 2009
Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity.

Induction of humoral immunity with plasmid DNA encoding an immunogenic fragment of Pasteurella haemolytica A1 leukotoxin

, 1999
Pneumonic pasteurellosis is an acute respiratory disorder that results from infection of the bovine lung by Pasteurella haemolytica A1. The primary virulence determinant is a secreted, ruminant-specific leukotoxin (LktA). The leukotoxin is a pore forming

Anti-idiotypic antibodies to a neutralizing epitope of Pasteurella haemolytica leukotoxin

, 1992
Pasteurella haemolytica A1 is commonly isolated from cattle exhibiting the shipping fever complex. Because pneumonic pasteurellosis is responsible for economic losses in the cattle industry, a vaccine to combat the disease is desired.
