Fatal locally invasive pulmonary aspergillosis occurred in a previously fit young patient who had no predisposing factors other than exposure to fungal spores in his occupation as a gardener.

Background: Much attention has been paid to poultry feed processing and the contamination In Iran in order to improve the production and reduce the waste.  No information is available on the fungal contamination and the strains found in processed (pellet) and non-processed (mash) poultry feeds. This study was designed to determine the hygienic condition and the risk of fungal contamination...

Asthma is a global problem that affects over 300 million people in the world. The main reason of asthma is allergy and atopy. Asthmatic patients are sensitized to allergens that can be resulting asthma attacks. Fungi as an allergen can be sensitized atopic people and present a severe asthma. Fungi have been found in water-damaged homes of asthmatic patients. Allergic asthma is associated with e...

Reactive oxygen and nitrogen species can have either harmful or beneficial effects on biological systems depending on the dose administered and the species of organism exposed, suggesting that application of reactive species can possibly produce contradictory effects in disease control, pathogen inactivation and activation of host resistance. A novel technology known as atmospheric-pressure non...

Skin immunity protects animals from airborne pathogen infection. Unlike mammals, arthropods, including insects, undergo periodic ecdysis to grow and develop. Newly molted insects emerge with unsclerotized thin cuticles but successfully escape pathogenic infections during the post-molt period. Here we show that prophenoloxidases (PPOs) in molting fluids remain bioactive on the integument and imp...

Tomato (Lycopersicon esculentum Mill.) seedlings, susceptible (cv. Pearson A-I Improved) and resistant (cv. Pearson Improved) to race 1 Fusarium oxysporum f. sp. lycopersici (Sacc.) Snyd &Hans., were inoculated with Meloidogyne javanica (Trueb) Chitwood second-stage juveniles and 3 weeks later with race 1 F. oxysporum f. sp. lycopersici spores. One week after fungal inoculation, no fungus was v...

Mucormycosis is an invasive fungal infection characterised by rapid filamentous growth, which leads to angioinvasion, thrombosis, and tissue necrosis. The high mortality rates (50-100%) associated with mucormycosis are reflective of not only the aggressive nature of the infection and the poor therapeutics currently employed, but also the failure of the human immune system to successfully clear ...

The spiroketal (E)-conophthorin has recently been reported as a semiochemical of the navel orangeworm moth, a major insect pest of California pistachios and almonds. Conophthorin and the isomeric spiroketal chalcogran are most commonly known as semiochemicals of several scolytid beetles. Conophthorin is both an insect- and plant-produced semiochemical widely recognized as a nonhost plant volati...

Fungal rhino sinusitis is a life threating, aggressive, angioinvasive infection caused by group of fungai called mucormycetes and aspergillus as well1. Spores these are present in the soil, air decaying material animal dungs. They inhaled swallowed to cause infection. It affects mainly immune compromised patients like uncontrolled diabetes (fungus grows flourish at high sugar level), organ tran...

OBJECTIVES To compare the efficacy and diagnostic value of four different sample collection techniques for cytological identification of nasal aspergillosis-penicilliosis in dogs. METHODS Fifteen dogs with a history of persistent nasal discharge and clinical and radiographic findings suggestive of aspergillosis were evaluated using four different cytological sampling techniques. These were a ...
