El estudio fue realizado con el propósito de identificar la micoflora asociada semilla amaranto (Amarantus hypochondriacus L.) y determinar si Macrophoma sp. es transmitido por esta vía ya que en regiones productoras se presenta forma epifitia manera enfítica existe evidencia patógeno semilla. En proveniente siembras comerciales cosechadas 1995, Tlaxcala, México, evaluó incidencia los patógenos...

Abstract Due to global shifts in climate, studies contrasting conditions of two natural and climatic zones are particular interest: (1) subzone mixed broad-leaved forests, (2) south-steppe subzone. In the period 2019-2020, 308 plant species from 56 families were surveyed. Phytopathogens damage plants, therefore increase loss quality materials. The frequency occurrence mycoses autumn is 2-14 tim...

Inhalation of fungal spores is shown to participate in the development of allergic rhinitis symptoms. In this study, relation between presence of Alternaria in the human nasal cavity and allergic rhinitis is assessed. In a case-control study, 58 allergic rhinitis patients were compared with a well-matched control group of fifty healthy volunteers for sensitization to Alternaria (by skin prick t...

Seed-borne pathogens reduce the quality and cause infections at various growth stages of horticultural crops. Some best-known are fungi genus Alternaria, that destructive vegetable other crop diseases, resulting in significant yield losses. Over several years, much attention has been paid to environmentally-friendly solutions for disease management regarding environmental damage caused by chemi...

sugar beet roots and attached soil are usually transferred to sugar factories for processing ,then the roots are washed by pressurized water. muddy water as waste flows in canal and is used to irrigate fields. the possibility of occurrence and fluctuations of the pathogenic organisms in waste were studied in 2005. the samples were collected from waste water once a week. isolation of pathogens w...

BACKGROUND Asthma afflicts 6% to 8% of the United States population, and severe asthma represents approximately 10% of asthmatic patients. Several epidemiologic studies in the United States and Europe have linked Alternaria sensitivity to both persistence and severity of asthma. In order to begin to understand genetic risk factors underlying Alternaria sensitivity and asthma, in these studies w...
