In Menoua Division, common bean (Phaseolus vulgaris L.) is amongst the legumes which are greatly cultivated with farmers growing different cultivar types. Upon harvest, these cultivars are stored to be used as food over the storage period or for sale. Unfortunately, appropriate facilities for storing the cultivars after harvest are not available hence predisposing the grains to fungi infection. The knowledge of cultivars resistant to damage by storage fungi would therefore have a consider...
In most parts of Cameroon particularly the Menoua Division, common bean (Phaseolus vulgaris L.) is usually consumed immediately after harvest or after a few months of storage. Contamination of common bean by fungi usually occurs in the field and during storage. It is possible that the incidence of food contamination by fungi varies between field and storage. The study aimed at determining the incidence of common bean infection by fungi during harvest and during storage. Six common bean cultiv...
ABSTRACT Various plant diseases (Fusarium ear rots, bean anthracnose and damping off of seedlings) caused by phytopathogenic agents are known to cause considerable crop losses to agricultural yield all over the world. The use of antagonistic microorganisms in controlling maize and bean pathogens is an area of great potential in order to increase yield, thereof mitigate food insecurity. The aim of this study was to characterize and screen selected tropical fungi and bacteria for antimicrobial ...
The purpose of this research work is to isolate and identify Using ID 32C API kit and to determine the antifungal sensitivity profile of fungi isolated from the mother and child dump site Akure, Ondo state, Nigeria. Ten isolates (Yeast, Aspergiliusflavus, Aspergiliusniger, Fusariumsolani, Candida albucan, Candida kruise, Phytoptera, Rhizopusstolonifer, Trichodermhorizianum,Fusariumvortezelium) were used for this research work.Potato Dextrose Agar was used to isolate and prepared for enume...
Abstract: Soybean (Glycine max L.) is among the most economically important legumes that provide more than 1/4 of food (for man) and animal feed. However, its yield is comparatively low, most especially under drought stress. The aim of this study therefore was to assess the ability of Rhizobium spp. and mycorrhizal fungi to enhance the yield, seed size and fatty acid content of soybean grown under semi-arid environment. Rhizobium sp. strain R1 was found to possess nitrogen-fixing gene conife...
Cutaneous mycoses infections of the skin, hair, or nails are recurring presentations in the geriatric primary care setting. The most common infections are those caused by dermatophytes. The genus Trichophyton gives rise to most of the tinea dermatophytoses, including tinea capitis, tinea pedis, and tinea unguium (cutaneousmycoses). Part of the diagnostic challenge lies in distinguishing the mycotic lesions from those caused by cutaneous diseases such as psoriasis, eczema, dyshidrosis, and con...
In Cameroon, common bean (Phaseolus vulgaris L.) is amongst the legumes which are greatly consumed. Farmers in Cameroon especially the Menoua Division grow different common bean cultivars which after harvest, are stored to be used as food over the storage period or for sale. Storage of agricultural products become prone to fungal infection over time. Studies on the microbiology of stored common bean has identified fungi as a major contaminant. However it is possible that the incidence an...
The present study was conducted from January to October 2018 in Mnanje, Mpeta and Naliendele villages to determine aflatoxin levels in dried groundnut kernels, to identify toxigenic and atoxigenic strains of Aspergillus section Flavi from soil samples and to test the effect of atoxigenic strains against aflatoxin-producing fungi in groundnut. Isolation of fungi was done on MRBA and AFPA media and analysis of aflatoxin levels in groundnut was conducted using HPLC. The results showed that,...
Abstract: Kakamega forest, a major reservoir of biodiversity in Kenya has experienced degradation over a long period of time due to human disturbance. This disturbance has resulted in a heterogeneous mixture of vegetation including disturbed primary forest, secondary forest, clearings and glades, and timber plantations. Restoration of the forest ecosystem has included the re-establishment of native tree species in order to accelerate recovery of the degraded areas and connect formally joined...
Abstract: Smallholder subsistence farming is important in the production of food crops for basic livelihoods and income generation in rural areas. However, yields have remained low due to high disease, weed and pest incidences. Currently, crop pests and diseases are largely controlled by use of chemicals, which have adverse effects on the environment and nontarget organisms. There is need for new methods that are environmentally safe to supplement existing control strategies in order to enha...
Abstract: Grapes (Vitis vinifera L.) are among the most widely consumed fruits for its asociated health benefits. Endophytic fungi are groups of fungi with very specific ecosystem inside plant tissues and produces varieties of secondary metabolites with medicinal and nutraceutical applications. The present study was undertaken to investigate production of bioactive extracts with antioxidant and antimicrobial potentials activities of endopytic fungi from red grape peel and seed. The antioxida...
In Kenya, maize is a staple food and is stored after harvest as a source of food and for sale. From the stored maize, the surplus from that meant for food is sold by some farmers to earn income. The quality of the maize in store depends on the storage facility. Poorly constructed and unmaintained structures may allow leakage of water and entry by rodents and insects which may mechanically damage the maize by nibbling and holing respectively, thus predisposing the grains to fungal infectio...
ABSTRACT Tomato production in Kenya, especially in the coastal region has remained low due to pests and diseases attack especially Meloidogyne spp. (root-knot nematodes) which is a serious threat. A study was therefore conducted in the coastal region of Kenya with the aim of sourcing for endophytic fungi (EF) which could be used alongside moderately resistant tomato cultivars to manage Meloidogyne spp. Pathogenecity test of these isolates was carried out in the screenhouse using cv. Cal J. In...
ABSTRACT A survey of, the mycoflora of three seed lots of Pinus caribaea var. hondurensis was carried out using the incubation tests for the detection of seed-borne fungi on agricultural seeds. The seed-borne fungi identified were: t Acromonium sp., Aspergillus flatus, fumigatus,! A. niger, A. tamarii, Botrvtis sp., BotryQdiplQd.i.a theobromae, Chaetomium funicola, £. globosum, £. indiCUTO, Cladosporium oxvsporum, Pendrophpma sp., Fysa.riym ecruiseti, F. moniliforme var. intermedium, Gii-pc...
Abstract Lake Magadi and Little Magadi are saline, alkaline lakes lying in the southern part of Kenyan Rift Valley. Their solutes are supplied by a series of alkaline hot springs with temperatures as high as 86°C. Previous culture-dependent and independent studies have revealed diverse prokaryotic groups adapted to these conditions. However, very few studies have examined the diversity of fungi in these soda lakes. In this study, amplicons of Internal Transcribed Spacer (ITS) region on Tota...
