Acacia oxyphylla Graham ex Bentham (Mimosaceae) is a leguminous plant widely used in the traditional medicines of north-east Indian tribes. Among the Mizo tribes, the stem bark is commonly used as fish stupefying and deworming agents. This present experiment was aimed at evaluating the nematocidal effect, if any, upon Ascaridia galli Schrank (Nematoda), the intestinal roundworm of domestic fowl...

The ultrastructure of cuticle formation was studied in the third molt of Nippostrongylus brasiIiensis, a parasite of rats. For comparative purposes, early events in the formation of adult cuticle during the fourth molt of Nematospiroides dubitts, a parasite of mice, were also examined. In the former, the third cuticle became separated from the hypodermis plasma membrane, and a filamentous coat ...

Hirsutella rhossiliensis and H. minnesotensis are endoparasitic fungi of the second-stage juvenile (J2) of the soybean cyst nematode (Heterodera glycines) in nature. They also parasitize both H. glycines J2 and Caenorhabditis elegans on agar plates. Agrobacterium tumefaciens-mediated transformation conditions were established for these Hirsutella spp. The resulting transformants were similar to...

Lectin-binding glycoproteins in seven populations of two burrowing nematode sibling species were probed with five different biotinylated lectins on Western blots, and differences were correlated with nematode ability to parasitize citrus and to overcome citrus rootstock resistance. Banding patterns of molecular weight standards were fit best by an exponential decay function, and a predictive eq...

Hirsutella rhossiliensis OWVT-1 has substantial potential as a biocontrol agent against plant-parasitic nematodes. Serine proteases have emerged as a potentially useful factor in the nematode-fungus interactions. When grown in liquid culture with the nematode Panagrellus redivivus as the sole nitrogen source, an extracellular alkaline protease (Hasp) was produced by the OWVT-1. The purified Has...

Understanding the desiccation survival attributes of infective juveniles of entomopathogenic nematodes (EPN) of the genera Steinernema and Heterorhabditis, is central to evaluating the reality of enhancing the shelf-life and field persistence of commercial formulations. Early work on the structural and physiological aspects of desiccation survival focused on the role of the molted cuticle in co...

The synthesis and localization of an endospore surface epitope associated with the development of Pasteuria penetrans was determined using a monoclonal antibody (MAb) as a probe. Nematodes, uninfected or infected with P. penetrans, were harvested at 12, 16, 24, and 38 days after inoculation (DAI) and then examined to determine the developmental stage of the bacterium. Vegetative growth of P. pe...

Abstract Plant‐parasitic nematodes (PPNs) are one of the most damaging pests to plants and able cause significant damage all parts plants, including stems, leaves, flowers, fruits roots. Studies on diversity, host range, distribution identification methods PPNs therefore vital in order create a basis for management. This current study represents first dedicated investigation from medicinal Viet...

Filarial nematodes (superfamily Filarioidea) are responsible for an annual global health burden of ∼6.3 million disability-adjusted life-years, which represents the greatest single component of morbidity attributable to helminths affecting humans. No vaccine exists for the major filarial diseases, lymphatic filariasis and onchocerciasis; in part because research on protective immunity against f...

Endoparasitic root-knot (Meloidogyne spp.) and lesion (Pratylenchus spp.) nematodes cause considerable damage in agriculture. Before they invade roots to complete their life cycle, soil microbes can attach to their cuticle or surface coat and antagonize the nematode directly or by induction of host plant defenses. We investigated whether the nematode-associated microbiome in soil differs betwee...
