Antimicrobial activities and phytochemical composition of extracts of Ficus species: An over view

  This paper reviews the antimicrobial research undertaken on  Ficus species. Antimicrobial methods [disc and well diffusion, minimum inhibitory concentration (MIC), minimum bacterial concentration (MBC)] were used to evaluate the different extracts. The majority of published articles use MIC assays for antimicrobial determination. An overview is given on the activities; extracts, compounds or...

Challenges and future prospects for Dengue vector control

  Dengue is a significant public health issue in urban and suburban areas. It is a viral disease transmitted by Aedes mosquitoes. Due to lack of specific antiviral treatment or vaccine against dengue, vector control presently appears to be the only effective method for dengue prevention and control. Various methods are in use for vector control depending upon geography and climatic conditions of the...

Genetic characterization of Fusarium oxysporum isolated from guava in northern India

  Fusarium oxysporum f. sp. psidii is a causal agent of wilt disease of guava in subtropical regions globally. The production of guava fruit is affected by wilt disease thus, there is a need to develop molecular markers for accurate, rapid, specific and sensitive diagnosis ofF. oxysporum. A set of species-specific primers were developed for amplification of the internal transcribed...

Screening, identifying and medium optimization of a lipase-producing filamentous fungus from soil for high chiral resolution of 1-phenylethanol

  The kinetic resolution of racemates by biocatalysis is one of the major routes to manufacture optically pure compounds. Lipase-producing microorganisms were screened from soil for chiral resolution of 1-phenylethanol in the study. One microorganism with high chiral resolution ability was isolated and identified as Rhizopusstolonifer by the sequence similarity analysis and construction of...

Parasporal crystal proteins of Bacillus thuringiensis strain BT6, originating from the faeces of Sika Deer, demonstrate anticoccidial activity against Eimeria tenella in chickens

  The parasporal crystal proteins (Cry) of Bacillus thuringiensis (Bt) strain BT6, which was isolated from Sika Deer faeces, exhibited a similar effect with diclazuril for controlling the infection with Eimeria tenella in chickens. A far more considerable body weight gain was found in the chickens treated with BT6 Cry proteins, as compared to chemical drug-treated groups, infected-untreated...

Microscopic study of Alternaria brassicae infection processes in Brassica juncea cultivars by drop plus agarose method

  Alternaria blight caused by Alternaria brassicae (Berk) Sacc. is one of the most serious diseases of Indian mustard [Brassica juncea (L.) Czern and Coss.] grown as edible oilseed crop in India. Poorly characterized tolerance mechanisms against this pathogen further confirm the strategies that can be undertaken to design durable resistance or effective disease control measures. The...
