BACKGROUND Many patients suffer from recurrent Staphylococcus aureus infections, but there are few data examining recurrence predictors. METHODS We followed adults and children after treatment for S. aureus skin infections and their household contacts in Los Angeles and Chicago. We surveyed subjects for S. aureus body colonization, household fomite contamination, and behavioral and clinical f...

Mycotoxins are a group of naturally occurring toxic chemical substances, produced by different fungal species, which can cause illness or even death due to their toxigenic, carcinogenic, mutagenic and teratogenic effects. Though more than 400 mycotoxins are known to have toxic effects on human when ingested along with contaminated food, mycotoxins like aflatoxins, ochratoxins, zeralenone, trich...

BACKGROUND Infectious disease interventions, such as vaccines and bed nets, have the potential to provide herd protection to non-recipients. Similarly, improved sanitation in one household may provide community-wide benefits if it reduces contamination in the shared environment. Sanitation at the household level is an important predictor of child growth, but less is known about the effect of sa...

1. The diagnosis of asymptomatic bacteriuria should be based on results of culture of a urine specimen collected in a manner that minimizes contamination (A-II) (table 1). • For asymptomatic women, bacteriuria is defined as 2 consecutive voided urine specimens with isolation of the same bacterial strain in quantitative counts 10 cfu/mL (B-II). • A single, clean-catch voided urine specimen with ...

Mycotoxins are metabolites of moulds that may be found in food and feed of plant and animal origin. This paper gives a short review of the agronomical methods and food and feed storage recommendations for the prevention of mould contamination. It describes the practical methods of feed decontamination and the use of feed additives where mycotoxin contamination prevention has failed. However, th...

background and objectives: paper and paperboard packaging play an important role in safety and quality of food products. common bacteria of paper and paperboard food packaging could grow due to specific conditions included humidity, tem- perature and major nutrition to contaminate the food. the purpose of this research was to investigate numbers and the types of bacteria in the food packaging p...

Organochlorine pesticides (OCPs) have been used worldwide, particularly in Africa, for several decades. Although many are banned, several African countries still use OCPs especially for the prevention and control of malaria. OCPs are characterized by their bio-accumulation in the environment, especially in the food chain, where they find their way into the human body. Despite no clear epidemiol...

Radiostrontium is foremost among the by-products of nuclear fission presently considered to be hazardous to man because it may be transmitted readily through the food chains leading to man 2 5 s 16. The main source of radiostrontium contamination of the natural environment has been from the fallout debris of nuclear detonations. It is probable that radiostrontium may continue to be dispersed in...
