A Sensory Code for Host Seeking in Parasitic Nematodes
Parasitic nematode species often display highly specialized host-seeking behaviors that reflect their specific host preferences. Many such behaviors are triggered by host odors, but little is known about either the specific olfactory cues that trigger these behaviors or the underlying neural circuits. Heterorhabditis bacteriophora and Steinernema carpocapsae are phylogenetically distant insect-...
متن کاملOlfaction shapes host-parasite interactions in parasitic nematodes.
Many parasitic nematodes actively seek out hosts in which to complete their lifecycles. Olfaction is thought to play an important role in the host-seeking process, with parasites following a chemical trail toward host-associated odors. However, little is known about the olfactory cues that attract parasitic nematodes to hosts or the behavioral responses these cues elicit. Moreover, what little ...
متن کاملDiverse Host-Seeking Behaviors of Skin-Penetrating Nematodes
Skin-penetrating parasitic nematodes infect approximately one billion people worldwide and are responsible for some of the most common neglected tropical diseases. The infective larvae of skin-penetrating nematodes are thought to search for hosts using sensory cues, yet their host-seeking behavior is poorly understood. We conducted an in-depth analysis of host seeking in the skin-penetrating hu...
متن کاملNuclear receptors in parasitic nematodes
Introduction One of the most prevalent classes of parasitic organisms is the helminth (parasitic worms), which collectively infect more than 1 billion people worldwide and cause a range of maladies including malnutrition, growth and mental retardation, disfigurement and physical disabilities, and death (1). Helminths that infect humans are generally considered to comprise two major phyla: Nemat...
متن کاملHost movement and the genetic structure of populations of parasitic nematodes.
Mitochondrial DNA (mtDNA) sequence data were used to compare the population genetic structures of five species of parasitic nematodes from three different hosts: Ostertagia ostertagi and Haemonchus placei from cattle, H. contortus and Teladorsagia circumcincta from sheep, and Mazamastrongylus odocoilei from white-tailed deer. The parasites of sheep and cattle showed a pattern consistent with hi...
