The Center for Forest Mycology Research (CFMR) at the Forest Products Laboratory in Madison, WI is one of the few remaining mycological research labs left in the USDA-Forest Service. Traditionally established to study the taxonomy of pathogenic root rot, sap-rot, and heart-rot fungi, the group has changed its focus in recent years towards the biosystematics and ecology of both pathogenic and sa...
b a ckground: microbes particularly bacteria presenting in the gut of haematophagous insects may have an important role in the epidemiology of human infectious disease. m e t hods: the microbial flora of gut and surrounding environmental of a laboratory strain of phlebotomus papatasi , the main vector of zoonotic cutaneous leishmaniasis (zcl) in the old world, was investigated. biochemical reac...
The effects of two Bacillus strains (Bacillus pumillus and B. licheniformis) on Medicago sativa plants were determined in single or dual inoculation with three arbuscular-mycorrhizal (AM) fungi and compared to P-fertilization. Shoot and root plant biomass, values of thymidine and leucine incorporation as well as ergosterol and chitin in rhizosphere soil were evaluated to estimate metabolic acti...
The world today is going through a series of uncalled events, that has hindered the balance livelihood in current population. This due to emergence COVID-19 but along with that, accompanied several other rare and extremely fatal fungal infections under its shadows, such as Mucormycosis. Mucormycosis caused particularly immunocompromised hosts by saprophytic fungi Mucorales species. infection le...
BACKGROUND/PURPOSE The genus Leptospira comprises pathogenic and saprophytic strains. Conventional methods for the identification of pathogenic leptospiral isolates are cumbersome and laborious. In view of these limitations, the search for alternative methods have been focused on DNA based techniques. In this study, we have developed an effective method for the rapid identification of pathogeni...
In their natural habitat, bacteria are consumed by bacterivorous nematodes; however, they are not simply passive preys. Here we report a defensive mechanism used by certain bacteria to mobilize nematode-trapping fungi to kill nematodes. These bacteria release urea, which triggers a lifestyle switch in the fungus Arthrobotrys oligospora from saprophytic to nematode-predatory form; this predaciou...
Mucormycosis is an acute, often fatal intection caused by saprophytic fungi, of the order Mucorales. It occurs in debilitated patients who are compromised immunologically due to uncontrolled diabetes lymphoma, corticosteroid treatment and radiotherapy (Jain et al., 1978). Only 13 cases were reported up to 1963 (Pilsbury and Fischer, 1977). The fungus appears in tissues as hyphae which are irreg...
In agricultural soils, fungi constitute most of the total microbial biomass in environment contributing with more than 50% soil biomass. The should be considered as a link production not only by their attributes but also for potential pathogenicity on crops chains. We aim to determine what extent combination management styles and tillage systems control specific cultivable fungal community stru...
