SEATTLE, Jan. 31, 2012 /PRNewswire-USNewswire/ -- The Infectious Disease Research Institute (IDRI) announced its technical support of the Sabin Vaccine Institute's (Sabin) first ever Phase 1 clinical trial of a human hookworm vaccine candidate, which began last week in Brazil. The trial is a very significant and a critical step toward developing a vaccine that would reduce the global burden of human hookworm by providing effective long-term protection for those who are most at risk....
Access to sanitation facilities, such as latrines, reduces by half the risk of becoming infected by parasitic worms that are transmitted via soil (soil-transmitted helminths) according to a study published in this week's PLoS Medicine. These findings are important as infection with parasitic worms can cause diarrhea, weakness, and malnutrition, which in turn can impair physical and mental development in children; they reinforce the importance of increased access to sanitation (a Millennium...
Scientists have long seen evidence of social behavior among many species of animals, both on the earth and in the sea. Dolphins frolic together, lions live in packs, and hornets construct nests that can house a large number of the insects. And, right under our feet, it appears that nematodes—also known as roundworms—are having their own little gatherings in the soil. Until recently, it was unknown how the worms communicate to one another when it's time to come together. Now, however,...
Planting tall fescue grass as a ground cover in peach orchards helps protect peach trees from nematodes that attack tree roots, according to U.S. Department of Agriculture (USDA) scientists. In a study published in the Journal of Nematology in 2010, Agricultural Research Service (ARS) plant pathologists Andy Nyczepir at the Southeastern Fruit and Tree Nut Research Laboratory in Byron, Ga., and Susan Meyer at the Nematology Laboratory in Beltsville, Md., tested several tall fescue varieties...
Caenorhabditis are usually thought of as soil nematodes, happily living in compost heaps. The famous (scientifically speaking) Caenorhabditis elegans has provided a wealth of information about developmental processes and cell death. These tiny worms have been at the forefront of three Nobel prizes and have even been sent into space! However all other known Caenorhabditis species are as distantly related to C. elegans as mouse is to man. New research published in BioMed Central's open access...
A U.S. Department of Agriculture (USDA) scientist has created a new weapon in the war being waged against the potato cyst nematode-a diagnostic test that identifies the type of nematode infesting a grower's field. Xiaohong Wang, a molecular biologist with the Agricultural Research Service (ARS) Robert W. Holley Center for Agriculture and Health in Ithaca, N.Y., has filed a patent application on the monitoring tool, developed in part by cloning and sequencing key genes. ARS is USDA's...
HORSHAM, Pa., July 11, 2011 /PRNewswire/ -- In a study sponsored by Topaz Pharmaceuticals Inc., a privately held specialty pharmaceutical company, scientists from the University of Massachusetts, Amherst presented data showing that a 0.5% ivermectin (IVM) cream formulation was active against lice eggs from permethrin resistant head lice. The data were presented in a poster presentation on Saturday, July 9, 2011 at the 37th Annual Meeting of the Society for Pediatric Dermatology in...
Today at the Neglected Tropical Diseases Meeting of the International Society for Infectious Diseases (ISID-NTD) in Boston, the Drugs for Neglected Diseases initiative (DNDi) announced the first research and development project in its new helminth infection drug portfolio to address unmet needs of patients in Africa and Asia.The project will assess the potential of the drug flubendazole to treat a highly neglected subset of helminth infections, notably co-infection of two of the three...
ALACHUA, Fla., June 28, 2011 /PRNewswire/ -- Pasteuria Bioscience has announced that it has entered into an exclusive global technology partnership with Syngenta, a world leader in agri-business focusing on sustainable agriculture. The agreement will allow for the development of innovative bio-nematicide products based on Pasteuria spp., a naturally-occurring soil bacteria long recognized as a promising biological control agent against nematodes. "We're excited to be working in...
MONHEIM, Germany, April 26, 2011 /PRNewswire/ -- - First Launches in Germany and Austria to Follow Shortly Bayer today announced that the European Commission has approved two new companion animal products: Veraflox(R) (pradofloxacin) and Procox(R) (emodepside and toltrazuril). Veraflox(R) is the first next-generation veterinary fluoroquinolone antibiotic for the treatment of bacterial infection in cats and dogs. Procox(R) is the first and only licensed combination treatment...

Trichuris suis is a species of whipworm that is classified within the Nematoda phylum. It can be found in warm tropical regions throughout the world but is rare in arid regions. Males reach an average body length between 1.1 and 1.5 inches, while females reach an average length between 2.3 and 3.1 inches. This species, and other members of the Trichuris genus, was given its common name because of its whip like appearance. The original definitive hosts of this species are pigs, but it is able...
Phasmarhabditis hermaphrodita is a species of roundworm that is classified within the Nematoda phylum. This species is found in soils where slug species from the Limacidae, Arionidae, and Milacidae families are located, with one common host being Deroceras reticulatum. The worm can be located in soil by using real-time PCR testing methods, a test that also distinguishes it from its similar relative, Phasmarhabditis neopapillosa. The life cycle of Phasmarhabditis hermaphrodita begins in...
Onchocerca volvulus is a species of roundworm that is classified within the Nematoda phylum. This species causes the disease onchocerciasis, more commonly known as river blindness. The life cycle of this species is dependent upon an intermediate host, typically the black fly, and a definitive host, which is always a human. Its lifecycle begins when a black fly ingests microfilariae from a human host by consuming blood. The microfilariae that were present in the skin of the human host now...
Trichinella spiralis, sometimes known as the pork worm, is a parasite within the Nematoda class. It can be found in pigs, rats, humans, and bears. This worm causes trichinosis in humans, most often from consuming undercooked pork. This species is the smallest within its class, reaching an average body length of .16 centimeters. Females are twice as large as males, displaying a sexual dimorphism. The reproductive organs of females are unique to the species in that the front end holds developed...
The soybean cyst nematode (Heterodera glycines) is a parasitic worm that infects soybean plants, and other legumes, across the world. It is thought to be native to Asia, but was found in the United States in 1954 and in Colombia in the 1980’s. It can be found in Italy and Iran and its most recent sightings have occurred in Brazil and Argentina, two major areas where soybeans are grown. These worms are highly damaging to American soybean crops, costing the industry as much as 500 thousand...
