(Academic Press, 2018-02-01)Background Resistant and virulent Staphylococcus aureus is a global public health challenge. Staphylococcal Bi-component leukotoxins are cytolytic to immune cells and evolve to disarm the innate immunity during infections, ... -
Rapid detection of carbapenemase-producing Acinetobacter baumannii and carbapenem-resistant Enterobacteriaceae using a bioluminescence-based phenotypic...
(Elsevier, 2014-04-01)Accurate detection of carbapenem-resistant Enterobacteriaceae (CRE) and carbapenemase-producing carbapenem-resistant Acinetobacter spp. (CP-CRA) constitutes a major challenge in laboratory diagnostics. We developed a ... -
Ecology and Physiology of Plant growth in relation to soil salinity
(2015)This work is intended as a review of soil salinity as one common abiotic stress in ecological systems that adversely affect plant growth. In arid and semi arid areas, saline areas or areas irrigated with saline waters, ... -
Chlorophyll fluorescence parameters and photosynthetic pigments of four Glycine max varieties under Aluminium chloride stress
(PSCI Publications, 2015)Soil acidity limits agricultural production globally. Different kinds of stresses, mainly Al stress, generated from acid soils affect plant growth and result in food shortage and production. General effects of Al ... -
Allelopathic potential of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis l.)
(2015)Invasive plant species when introduced into new environments may result into a number of ecological problems (Howard et al., 2000). They may influence other species through pathways such as allelopathy or phytotoxicity ... -

Growth changes of seven Amaranthus (spp) during the vegetative and reproductive stages of development as influenced by variations in soil water deficit
(International Journal of Research and Innovations in Earth Science, 2015)Soil water deficit is a principal a biotic factor that limits plant growth and development in dry areas. Insufficient moisture contributes to soil water deficit and some negative effects on Amaranthus (spp) such as reduced ... -
Allelopathic effects of mexican sunflower [tithonia diversifolia (hemsl) a. Gray] on germination and growth of cowpea seedlings (vigna sinensis)
(2014)Allelopathy is a common among plants. Allelopathic substances affect seed germination, plant growth and development or even affect chlorophyll synthesis by the plant leaves. Tithonia diversifolia contains allelochemicals ... -
