Host nutrition is thought to affect the establishment, persistence, and severity of pathogenic infections. Nutrient-deficient foods possibly benefit pathogens by constraining host immune function or benefit hosts by limiting parasite growth and reproduction. However, the effects of poor elemental food quality on a host's susceptibility to infection and disease have received little study. Here w...

The feeding apparatus of Pratylenchus penetrans (Cobb) Chitwood and Oteifa was studied by means of the electron microscope. The stomatostylet is composed of tooth, shaft, and basal knobs. The tooth and shaft are closely interlocked. The tooth forms the outer covering and the inner lining of the anterior half of the stylet, whereas the shaft extends from the basal knobs to the level of the style...

Tunga penetrans (L.) and T. trimamillata Pampiglione et al. are the unique species of the genus parasiting men. While morphological identification of gravid females is possible, the diagnosis on non-gravid females, males or body fragment is quite difficult, time consuming and often requires taxonomic experience. In this paper we present a protocol for the diagnosis of these species based on the...

Representatives of 15 nematode genera were viewed with 450-490-nm epi-illumination and found to autofluoresce. The autofluorescence was limited to 1-5-mum-d globules in the intestinal cells of live nematodes. When adult Pratylenchus penetrans or Caenorhabditis elegans were killed with formaldehyde, freezing, or heat, autofluorescence dispersed throughout the body. Mixed stages of P. penetrans w...

New nematicides named fumiquinones A (1) and B (2), together with spinulosin (3), LL-S490beta (4), and pseurotin A (5), were isolated from Aspergillus fumigatus and their structures were established by spectroscopic methods including 2D-NMR. Compound 1 showed effective nematicidal activities against Bursaphelenchus xylophilus and Pratylenchus penetrans without inhibiting plant growth except for...

A novel mushroom in the genus Gymnopilus was observed rainy season (June – November 2022) Adenta Municipality of Greater Accra Region, on a pile dry wood earmarked for firewood. The fruiting body produced prolific basidiospores akin to order Agaricales gilled mushrooms. small medium size and solitary groups, appearing cream brown colour later turning rusty with age. stipe solid tapering towards...
