Assessment of fungal pathogens associated with orange spoilage

Citrus sinensis also known as sweet orange is the most popular of the citrus fruits. It is widely cultivated in most regions of the world possessing a rich source of vitamin C, flavonoids, phenolic compounds and pectin. This research was conducted to investigate the assessments of fungal pathogens associated with orange fruit spoilage sold in five markets in Benin metropolis and the possible public health implications....

Antifungal activity of Citharexylum quadrangulare Jacq. extracts against phytopathogenic fungi

Antifungal activity of Citharexylum quadrangulare Jacq., an exotic tree introduced in Tunisia many years ago, was evaluated. Organic extracts using hexane, ethyl acetate and methanol solvents together with aqueous extracts tested at different concentrations were prepared from different organs (roots, stems, leaves and flowers). The fungitoxic activity for all extracts was evaluated against five phypathogenic fungi...

Efficacy of Aeromonas hydrophila S-layer bacterins with different protein profiles as a vaccine in Nile tilapia (Oreochromis niloticus)

Farming of Nile tilapia is in full development throughout the world. However, an increase is still seen in the prevalence and severity of bacterial diseases. The aim of this study was to develop a vaccine against Aeromonas hydrophila in Nile tilapia (Oreochromis niloticus) based on protein patterns of S-layer proteins. The proteins were extracted using glycine and NaOH with subsequent visualization through SDS-PAGE....

Occurrence of Salmonella sp. and Escherichia coli in free-living and captive wild birds from 2010-2013 in Guarapuava, Paraná, Brazil

Birds are increasingly close to men, and many times are raised as pets. However, many times, these animals may carry and spread enterobacteria that are deleterious to human health. Salmonella sp. is considered one of the most common zoonoses in the world, causing important losses to public health. Although, Escherichia coli is an important commensal in the gastrointestinal tract of most animals, it may cause disease...

Antifungal and enzyme activity of endophytic fungi isolated from Ocimum sanctum and Aloe vera

The present study was carried out to isolate endophytic fungi from Ocimum sanctum and Aloe vera and to assess their antifungal activity against Rhizoctonia solani, Fusarium oxysporum, Colletotrichum falcatum and Helminthosporium maydis. The isolated fungi were further evaluated for production of extracellular enzymes such as amylase, cellulase, chitinase, pectinase, laccase, lipase and urease. During the study 18...

Evaluation of the antagonistic effect of six mixed cultures of lactic acid bacteria, isolated from the Ethiopian fermented milk ergo, against some foodborne pathogens inoculated into the Ethiopian cottage cheese ayib

The antagonistic effect of mixed lactic acid bacterial cultures against foodborne pathogens (Staphylocuccus aureus ATCC 25923, Shigella boydii clinical isolate, Pseudomonas aeruginosa ATCC 25853) was evaluated in pasteurized ayib stored at room temperature. The lactic acid bacteria (LAB) were tested for acid tolerance at pH 2.0, 2.5, 3.0 and 3.5 for three and six h and for bile tolerance for 24 and 48 h at 0.3% (w/v)...
