Although the adverse health consequences of ingestion of food contaminated with aflatoxin B1 (AFB1) are known, relatively few studies are available on the adverse effects of exposure in occupational settings. Taking this into consideration, our study was developed aiming to elucidate the possible effects of occupational exposure to AFB1 in Portuguese swine production facilities using a specific...

Chaetomium globosum is one of the most common fungi that grows in damp buildings and occurs in agricultural and forestry workplaces. Using sera from atopic patients, we characterized and purified an extracellular chitosanase (Chg47) from C. globosum that is antigenic to humans. The study reports the production of monoclonal antibodies to the protein. Three capture ELISAs were developed for Chg4...

The prevalence and population density of the mycobiota of 50 samples belonging to 10 kinds of spices (anise, black pepper, red pepper, black cumin, peppermint, cardamom, clove, cumin, ginger and marjoram) which collected from different places in Jeddah Governorate were studied. The natural occurrence of mycotoxins in those samples was also investigated. Fifteen genera and thirty - one species o...

In-vitro antimicrobial and antioxidant activities of various concentrations ranging from 150 to 500 μg/ml of alcoholic (methanol and ethanol) extracts of Rumex dentatus were analyzed on different clinical bacterial strains (Shigella flexneri, Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhimurium, Staphylococcus aureus) and fungal strains (Aspergillus versicolor...

Microbiological and physicochemical characteristics of swimming pools in South Eastern states of Nigeria (Akwa Ibom and Cross River) were investigated. The bacterial isolates included Enterococcus faecalis, Clostridium perfringens, Bacillus cereus and Escherichia coli. Others were Pseudomonas aeruginosa, Staphylococcus aureus, Proteus vulgaris and Staphylococcus epidermidis, while fungal isolat...

We investigated the ability of Trametes versicolor and Pycnoporous cinnabarinus to metabolize triclosan. T. versicolor produced three metabolites, 2-O-(2,4,4'-trichlorodiphenyl ether)-beta-D-xylopyranoside, 2-O-(2,4,4'-trichlorodiphenyl ether)-beta-D-glucopyranoside, and 2,4-dichlorophenol. P. cinnabarinus converted triclosan to 2,4, 4'-trichloro-2'-methoxydiphenyl ether and the glucoside conju...

Pityriasis versicolor is a common superficial fungal infection of the skin which is caused by various species of yeast of the genus Malassezia and is clinically characterized by scaly hypo pigmented or hyper pigmented macules usually involving the upper trunk, upper arms, neck and abdomen [1]. Lesions of pityriasis versicolor confined to face has rarely been reported. In this article the author...

Isolates of Trichoderma, Penicillium, and Aspergillus were tested against Trametes versicolor and Neolentinus lepideus by agar interaction tests and by measuring the toxicity of culture filtrates. Some isolates were able to overgrow and kill both of the decay fungi in agar culture but others were totally ineffective. Although the filtrate from most isolates produced some growth inhibition of th...
