GC-MS analysis of bioactive compounds and evaluation of antimicrobial activity of the extracts of Daedalea elegans: A Nigerian mushroom

Phytochemicals are naturally occurring compounds present in varying levels in plants and help significantly in protecting them against pathogens. The chemical composition of acetone and ethanolic extracts of Daedalea elegans were determined using Gas Chromatography-Mass Spectrometry. Twenty-eight and fourty-four compounds were identified in the acetone and ethanolic extracts respectively. Only four compounds were found...

Diversity of arbuscular mycorrhizal fungi (AMF) associated with cotton (Gossypium hirsutum L.) growing in the Far-North region of Cameroon

The present study was carried out with the aim of highlighting the diversity of arbuscular mycorrhizal fungi (AMF) associated with the rhizosphere of cotton grown in the Far-North region of Cameroon. To achieve this, composite soil and root samples were taken in six fields, chosen according to edapho-climatic conditions and types of cultural practices. After entrapping the glomales in the greenhouse, the roots of the...

Phenotypic detection of extended spectrum β-lactamase and Metallo β-lactamase production by Gram negative uropathogens after exposure to gamma radiation

Eighty-five uropathogen isolates were collected and differentiated on the basis of their Gram stain reaction. Among the collected isolates, 25 (29.4%) were Gram positive cocci and 60 (70.6%) were Gram negative bacilli. Antibiotic susceptibility profile towards 15 different antibiotics concluded that impenime (IMP), amikacin (AK) and Pipperacillin/tazobactam (TZP) were the most effective against Gram negative; while...

Isolation of an emerging thermotolerant medically important Fungus, Lichtheimia ramosa from soil

Lichtheimia ramosa, a ubiquitous clinically important mould was isolated during a screen for thermotolerant fungi obtained from soil on a freshly burnt field in Ikorodu, Lagos State. In the laboratory, as expected it grew more luxuriantly on Potato Dextrose Agar than on size limiting Rose Bengal Agar. The isolate had mycelia with a white cottony appearance on both media. It was then identified based on morphological...

Fungal diversity within organic and conventional farming systems in Central Highlands of Kenya

Fungal diversity in agro-ecosystems is influenced by various factors related to soil and crop management practices. However, due to the complexity in fungal cultivation, only a limited number has been extensively studied. In this study, amplicon sequencing of the Internal Transcribed Spacer (ITS) region was used to explore their diversity and composition within long-term farming system comparison trials at Chuka and...

Presence of phytopathogenic fungi and oomycetes on rice and avocado crops in Tolima (Colombia)

Tolima is one of the largest zones in Colombia where avocado and rice are produced. The disease management programs for these crops are mainly chemical-dependent and tend to have variable results since the diagnosis of some diseases is based on unspecific symptoms. In this context, the present study aims to bring information about the phytopathogens affecting Tolima´s rice and avocado crops. From foliar tissue,...

Evaluating the efficacy of household filters used for the removal of bacterial contaminants from drinking water

Due to the erratic nature of microbial contaminants in drinking water, private and municipality water supply systems failed to deliver safe drinking water to households. In Ethiopia, there is lack of data and knowledge on the effectiveness of filter devices used to treat drinking water at household. This study aims to evaluate efficiency of household point of use filter devices (membrane filter, membrane with activated...

First novel phages from rodents with lytic activity on clinical Enterobacteriaceae strains: Initiation for phage therapy in West Africa

Bacteriophages (phages) are viruses that infect bacteria. The emergence of resistant bacteria has been reported worldwide. The use of phages to treat bacterial infection or to reduce bacteria load has become a new area of interest. The viral colonization of rodents represents an important source for a specific biotope. The objective of this study is to characterize the effect of novel phages isolated from rodents...
