over one-year period, 150 pasture soil samples and 138 sheep faecal samples, collected from different parts of iran were screened for the presence of nematophagous fungi. the samples were cultured at 25ºc on chloramphenicol-2% water agar (chf-wa) plates in the presence of haemonchus contortus third stage larvae (l3) and checked over a two-month period for characteristic conidia, conidiophores a...

The frequency of invasive mycoses due to opportunistic fungal pathogens has increased significantly over the past two decades (35, 74, 83, 88, 89, 101, 106). This increase in infections is associated with excessive morbidity and mortality (33, 50, 108) and is directly related to increasing patient populations at risk for the development of serious fungal infections, which includes individuals u...

Abstract The identification of novel anti-infective agents synthetic and natural origin represents one the main aims contemporary drug discovery. In current work, four different varieties Nicotiana tabacum , namely, K399, SPG28, Swat No. 1, 2, were studied to assess antibacterial antifungal properties their extracts. extracts contain anthraquinones, alkaloids, saponins, terpenoids, tannins, res...

Although the pathogenesis of multiple sclerosis remains obscure, much pathological and clinical evidence suggests an infective agent as a possible aetiological factor. If such an agent is responsible for initiating the disease it seems probable that there is a latent period of several years before the development of clinical features of multiple sclerosis. By that time it might be impossible to...

I is one of the important causes for the inflammation of the joint (arthritis). Microorganisms which include bacteria, viruses, fungi and parasites can cause arthritis, which can be acute or chronic. Acute arthritis is generally caused by pyogenic bacteria and termed as septic arthritis. Chronic arthritis is generally caused by mycobacteria and fungi. In reactive arthritis and other forms of sp...

PURPOSE OF REVIEW Fungal spores are ubiquitously present in indoor and outdoor air. A number can act as aeroallergens in Immunoglobulin E (IgE)-sensitized individuals and some thermotolerant fungi germinate in the lung where they can cause a combined allergic and infective stimulus leading to a number of clinical presentations characterized by evidence of lung damage. We discuss which biomarker...
