Parasitic nematodes cause chronic, debilitating infections in both livestock and humans worldwide, and many have developed multiple resistance to the currently available anthelmintics. The protective collagenous cuticle of these parasites is required for nematode survival and its synthesis has been studied extensively in the free-living nematode, Caenorhabditis elegans. The collagen synthesis p...
More than a quarter of the world's population is infected with nematode parasites, and more than a hundred species of nematodes are parasites of humans [1-3]. Despite extensive morbidity and mortality caused by nematode parasites, the biological mechanisms of host-parasite interactions are poorly understood, largely because of the lack of genetically tractable model systems. We have demonstrate...
We have established Meloidogyne hapla as a tractable model plant-parasitic nematode amenable to forward and reverse genetics, and we present a complete genome sequence. At 54 Mbp, M. hapla represents not only the smallest nematode genome yet completed, but also the smallest metazoan, and defines a platform to elucidate mechanisms of parasitism by what is the largest uncontrolled group of plant ...
the present study is based on the investigation of a soil hyphomyces, paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode meloidogyne javanica on tomato in greenhouse conditions. p. lilacinus, effectively promoted the growth of plants inoculated with m. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...
Strongyloides stercoralis is a free living tropical and semitropical soil nematode which its larva penetrates skin. It can complete its life cycle in human body and causes autoinfection. Most patients have no frank symptoms. But respiratory, gastrointestinal and skin manifestation may occur. We report a 76 year old man admitted to emergency room with muscle weakness, dyspnea, nausea, v...
two fungal species glomus mosseae and glomus intraradices as well as meloidogyne javanica nematode were used in order to evaluate the effects of arbuscular mycorrhizal fungi on control of different populations of root-knot nematode in tomato. a greenhouse test was established as factorial experiment based on completely randomized design with 8 treatments and 4 replicates followed by mycorrhizal...
Rhabditis pellio Schneider (nematoda) from the earthworm, Aporrectodea trapezoides Duges (Annelida).
Studies were conducted on the behavior of the nematode, Rhabditis pellio, in the earthworm, Aporrectodea trapezoides, from southern California. Juvenile and adult nematodes were found in the bladders and tubules of the metanephridia of the host. Similar nematodes that entered the coelom were encapsulated and incorporated into multiple capsules ("brown bodies"). It was demonstrated that this hos...
The complete genome sequence of the free-living nematode Caenorhabditis elegans was published 4 years ago. Since then, we have seen great strides in technologies that seek to exploit this data. Here we describe the application of some of these techniques and other advances that are helping us to understand about not only the biology of this important model organism but also the entire phylum Ne...
