ABSTRACTThis study reports on an emerging fungal disease of the edible crab,Cancer pagurus. Juvenile (prerecruit) crabs were found to be subject to this disease condition during the months of May to September at two intertidal sites in South Wales, United Kingdom. Histopathology revealed that the fungi overwhelm the host response in the tissues, leading to progressive septicemia. The causative agent of this infection was isolated and grown in pure culture and was identified as a member of theOphiocordycepsclade by sequencing of the small subunit of the fungal ribosomal DNA (rDNA). Of the crabs naturally infected with the fungus, 94% had a coinfection with the parasitic dinoflagellateHematodiniumspecies. To determine if there was any interaction between the two disease-causing agents, apparently fungus-free crabs, both with and without naturalHematodiniuminfections, were challenged with the fungal isolate. The presence ofHematodiniumcaused a significant reduction in fungal multiplication in the hemocoel of the crabs in comparison to that inHematodinium-free individuals. Histopathology of coinfected crabs showed a systemic multiplication ofHematodiniumwithin host tissues, leading to a rapid death, whileHematodinium-free crabs experimentally infected with the fungal isolate died due to fungal sepsis (septicemia) with the same characteristic pathology as seen in natural infections.

ABSTRACT The taxonomically uncharacterized nematophagous fungus ARF18, which parasitizes cysts, juveniles, and adults of the soybean cyst nematode (Heterodera glycines), was proposed as a nematode biological control agent in 1991. A 46.3-Mb draft genome sequence of this fungus is presented, and a tentative taxonomic identification as a novel species of Brachyphoris is proposed.

Has been done Isolation, Characterization and Secondary Metabolite Endophytic Fungal Isolate from Peronema canescens Jack Leave and Coptosapelta tomentosa Valeton K. Heyne Root. The aim of this research is to know the number of fungal isolates, chromatogram profile and secondary metabolite group of endophytic fungal isolates from P. canencens leaves and C. tomentosa root. Characterization of endophytic fungal isolates was done macroscopically and microscopically. Identification of secondary metabolites endophytic fungal isolates were performed by chemical reaction test and TLC (Thin Layer Chromatography) method with specific spray reagents. The data of this study were obtained based on the number of endophytic fungal that can be isolated, observing macroscopic and microscopic morphological profiles, chromatogram profile and secondary metabolites of each endophytic fungal isolated. The results showed that endophytic fungal that can be isolated from P. canencens leaves four isolates, and two isolates from C. tomentosa root. Morphological profile macroscopic endophytic fungal of the six isolates showed a greenish-colored colony, white gray, clear black. Microscopic profile of each fungal isolate having spores, sprangiosphora, sporangium, conidia, hyphae and stolon. The identified secondary metabolites are: alkaloids, terpenoids, and flavonoids, and polyphenols.
