Social organisms face a high risk of epidemics, and respond to this threat by combining efficient individual and collective defences against pathogens. An intriguing and little studied feature of social animals is that individual pathogen resistance may depend not only on genetic or maternal factors, but also on the social environment during development. Here, we used a cross-fostering experime...

Social insect colonies function cohesively due, in part, to altruistic behaviors performed towards related individuals. These colonies can be affected by parasites in two distinct ways, either at the level of the individual or the entire colony. As such, colonies of social insects can experience conflict with infected individuals reducing the cohesiveness that typifies them. Parasites of social...

The purpose of this study is to understand spatio-temporal changes of active fungal biomass and water in Tricholoma matsutake soil colonies during the mushroom fruiting season. The active fungal biomass was estimated by analyzing ergosterol content at four different points within four replicated locations in a single circular T. matsutake colony at Ssanggok valley in the Sogri Mt. National Park...

Background: Dermatophytoses are commonly encountered fungal diseases prevalent in most parts of the world especially in tropical countries. It is a superficial mycotic infection affecting hair, skin and nails. The present study was carried out to determine the incidence of dermatophytoses and their etiological agent in different age groups attending the Dermatology department. Methods: A total ...

Selection of fungal strains with high virulence against the developmental stages of Bemisia tabaci was performed using internal transcribed spacer regions. The growth rate of hyphae was measured and bioassay of each developmental stage of B. tabaci was conducted for seven days. All of the fungal strains tested were identified as Lecanicillium spp., with strain 4078 showing the fastest mycelium ...

numerous date palm orchards in south kerman, iran were investigated during 2001-2003. symptoms of leaf die-back appeared as light brown stripes which began at leaf tips and extended to leaf ends. infected tissues were surface sterilized with 0.05% sodium hypochlorite and, plated on pda medium. isolated fungi were purified using hyphal tip method. on pda medium, fungal colony was fluffy, first c...

Mustard (Brassica juncea L.) is the second most important oilseed commodity in India. Alternaria blight (Alternaria brassicae) one of devastating fungal pathogen, resulting severe yield losses to crop. The present study conducted in-vitro know effect different temperature regimes and various culture media on mycelial growth sporulation A. brassicae. It clearly evident from results that all test...

Bacterial-fungal interactions are important in the functioning of natural ecosystems. We examined possible synergistic or antagonistic effects during degradation polycyclic aromatic hydrocarbons (PAHs) by a fungal–bacterial co-culture. Bacteria and fungi were grown liquid nutrient medium supplemented with PAH substrates. The PAHs identification metabolites checked HPLC. Enzyme activities spectr...
