OBJECTIVES (1) Present a unique case of a thyroglossal duct cyst (TGDC) excised for recurrent infections with Trichinella spiralis in adjacent strap muscle; (2) review the literature regarding the diagnosis and treatment of subclinical trichinellosis of the head and neck. STUDY DESIGN Case report and literature review. METHODS Case report and literature review. RESULTS We present the case...

Plant parasitic nematodes can devastate walnut orchards and may remain dormant deep in the soil profile for several years, beyond reach of traditional pesticides. Nematicides are often very toxic to beneficial organisms and detrimental to the environment; several of the most effective are being phased out. Developing novel methods of diagnosis and control requires characterizing pathogens and t...

In healthy cotton, except for random occasional occurrence in cortical cells, terpenoid aldehydes (TA) are localized in the epidermis and, even there, are absent from the tip 2-4 cm of the root. Since constitutive TA do not occur in the endodermis and stele of the root, they cannot be effective agents against the development of the sedentary stage of the root-knot nematode, Meloidogyne incognit...

The precise mechanism of the very effective therapeutic effect of gastrointestinal nematodes on some autoimmune diseases is not clearly understood and is currently being intensively investigated. Treatment with living helminths has been initiated to reverse intestinal immune-mediated diseases in humans. However, little attention has been paid to the phenotype of nematodes in the IBD-affected gu...

Nematode infections are a ubiquitous feature of vertebrate life. In nature, such nematode infections are acquired by continued exposure to infective stages over a prolonged period of time. By contrast, experimental laboratory infections are typically induced by the administration of a single (and often large) dose of infective stages. Previous work has shown that the size of an infection dose c...

Damaged and developing kernels of peanut (Arachis hypogaea) are susceptible to colonization by fungi in the Aspergillus flavus group which, under certain conditions, produces aflatoxins prior to harvest. Our objective was to determine whether infection of peanut roots and pods by Meloidogyne arenaria increases aflatoxin contamination of the kernels when peanut is subjected to drought stress. Th...

Disease susceptibility is linked to nutritional status for a wide range of human and animal diseases. Nutritional status can influence both resistance (ability to resist the pathogen) and resilience (ability to tolerate or ameliorate the effects of the pathogen). This review focuses on the nutritional modulation of gastro-intestinal nematode infection in domestic ruminants, primarily sheep. It ...

Advanced third-stage larvae (body length 2.92 to 5.49 mm) of the fish nematode Raphidascaris biwakoensis Fujita, 1928 were found as frequent parasites of the leptodorid cladoceran Leptodora kindti (Focke) in Lake Biwa, southern Honshu, Japan, in July 1995. This is the first confirmed record of the L3 of this nematode species from an invertebrate host, showing that L. kindti may serve as a true ...

The nematode Caenorhabditis elegans is proving to be a powerful invertebrate model to study host-pathogen interactions. In common with other invertebrates, C. elegans relies solely on its innate immune system to defend itself against pathogens. Studies of the nematode response to infection with various fungal and bacterial pathogens have revealed that the innate immune system of C. elegans empl...
