The Pleosporaceae is an important loculoascomycete family. There has been disagreement, however, regarding the taxonomic placement of many genera within this family. This study investigates phylogenetic relationships among the genera Cochliobolus, Kirschsteiniothelia, Leptosphaerulina, Macroventuria, Pleospora, Pyrenophora, and Wettsteinina. Partial 28S rDNA sequences from taxa within these gen...

Epidemiological surveys support that asthma affects 5-30% of children and 2-30% of adults [1, 2]. This wide range of inter-survey fluctuation is mainly due to the different geographic distribution and to the use of different criteria among studies. Researchers characterize it as “a chronic allergic disease of airways” [3]. Rhinitis affects 40% of the population. The term respiratory allergy ref...

A patient is described in whom a clinical picture resembling allergic bronchopulmonary aspergillosis was found to be caused by hypersensitivity to the fungus Stemphylium lanuginosum. Bronchopulmonary reactions to antigens other than Aspergillus may be more frequent than is currently believed.

Stemphylium lycopersici is an important pathogen causing leaf spot of tomatoes worldwide. Although much information is available about the pathogen, little is known about dynamics of S. lycopersici in tomato fields. Seventy-nine symptomatic leaf samples were collected from two tomato cultivars grown in a farm (Miral and Inbred line). Fungal species associated with the disease were isolated on p...

background neisseria lactamica as one of the main commensal in oropharynx during the childhood is related to the induction of a natural immunity against meningococcal meningitis. also moraxella catarrhalis in oropharynx of children is a predisposing factor for otitis media infection. objectives the current study aimed to investigate the frequency of the n. lactamica, other nonpathogenic neisser...
