There are two main groups of biological agents regarded as occupational hazards: allergenic and/or toxic agents forming bioaerosols, and agents causing zoonoses and other infectious diseases. Bioaerosols occurring in the agricultural work environments comprise: bacteria, fungi, high molecular polymers produced by bacteria (endotoxin) or by fungi (β-glucans), low molecular secondary metabolites ...

Trichoderma species are soil-borne filamentous fungi widely utilized for their many plant health benefits, such as conferring improved growth, disease resistance and abiotic stress tolerance to their hosts. Many Trichoderma species are able to produce the auxin phytohormone indole-3-acetic acid (IAA), and its production has been suggested to promote root growth. Here we show that the production...

identification of host blood meal in haematophagous arthropods is an important element in their rule in transmission of vector borne diseases. the effects of post ingestion and physical conditions that killed mosquitoes are stored on the success of detecting blood meal dna of anopheles stephensi and culex quinquefasiatus was investigated by polymerase chain reaction (pcr) amplification at the h...

Mosquitoes enjoy wide geographical distribution and act as vectors for diverse pathogenic organisms from viruses to protozoans. Mosquito-borne diseases have a long history with some of them like Malaria dominating the scene for centuries. New diseases like Dengue fever, Zika viral disease etc. get added to the list from time to time. Vector control is an effective and widely accepted strategy i...

Salinity causes disturbance in symbiotic performance of plants, and increases susceptibility of plants to soil-borne pathogens. Endophytic bacteria are an essential determinant of cross-tolerance to biotic and abiotic stresses in plants. The aim of this study was to isolate non-rhizobial endophytic bacteria from the root nodules of chickpea (Cicer arietinum L.), and to assess their ability to i...

since the mid-19 th century, human activities have increased greenhouse gases such as carbon dioxide, methane, and nitrous oxide in the earth's atmosphere that resulted in increased average temperature. the effects of rising temperature include soil degradation, loss of productivity of agricultural land, desertification, loss of biodiversity, degradation of ecosystems, reduced fresh-water resou...

background: almost one third of the global population is living in developing south asia where disease occurrence is high especially in rural areas and people are unaware of water-borne diseases and cost of illness. methods: the quantitative approach involved questionnaire based study (n=50 households). the community awareness, the occurrence of water-borne diseases with related cost of illness...

Submit Manuscript | http://medcraveonline.com vegetables and flowers. Practicing of grafting in vegetable crops is an exclusive tool in East Asia to manage various vulnerable issues to the intensive vegetable production. In this regard, the first scientific report of vegetable grafting was published during late 1920 in Japan Journal of Horticulture [1]. This study was designed to control soil b...
