Anticoagulant repertoire of the hookworm Ancylostoma caninum.
Hookworms are hematophagous nematodes that infect a wide range of mammalian hosts, including humans. There has been speculation for nearly a century as to the identity of the anticoagulant substances) used by these organisms to subvert host hemostasis. Using molecular cloning, we describe a family of potent small protein (75-84 amino acids) anticoagulants from the hookworm Ancylostoma caninum t...
متن کاملAncylostoma caninum anticoagulant peptide: a hookworm-derived inhibitor of human coagulation factor Xa.
Human hookworm infection is a major cause of gastrointestinal blood loss and iron deficiency anemia, affecting up to one billion people in the developing world. These soil-transmitted helminths cause blood loss during attachment to the intestinal mucosa by lacerating capillaries and ingesting extravasated blood. We have isolated the major anticoagulant used by adult worms to facilitate feeding ...
متن کاملExperimental human infection with the dog hookworm, Ancylostoma caninum.
OBJECTIVE To investigate possible routes for human infection by the dog hookworm (Ancylostoma caninum). DESIGN, SETTING AND PARTICIPANT: Relatively small numbers of infective larvae were administered orally and percutaneously to an informed healthy volunteer (J K L) under medical supervision, at intervals between May 1998 and May 1999. MAIN OUTCOME MEASURES Symptoms; weekly blood eosinophil c...
متن کاملThe canine hookworm genome: analysis and classification of Ancylostoma caninum survey sequences.
Hookworms infect nearly a billion people. The Ancylostoma caninum hookworm of canids is a model for studying human infections and information from its genome coupled with functional genomics and proteomics can accelerate progress towards hookworm control. As a step towards a full-scale A. caninum genome project, we generated 104,000 genome survey sequences (GSSs) and determined the genome size ...
متن کاملMitochondrial DNA variation of the dog hookworm Ancylostoma caninum in Brazilian populations.
The mitochondrial cytochrome oxidase I gene was partially sequenced for 164 Ancylostoma caninum individuals, originating from five different localities in Brazil, with the aim of describing the genetic diversity and genetic structure of Brazilian hookworm populations. Allelic and nucleotide diversity were moderate (overall h=0.88 and pi=0.016) and were similar among cities. There was moderate g...
