Peanut is an important cash crop both for commercial and small-scale farmers in South Africa. The effect of Ditylenchus africanus on peanut is mainly qualitative, leading to downgrading of consignments. This nematode is difficult to control because of its high reproductive and damage potential. The objective of this study was to identify peanut genotypes with resistance to D. africanus that wou...

In 2010, a team of US researchers concluded that the more peanuts a pregnant woman ate during her pregnancy [4], the more likely her newborn was to be sensitive to peanuts. They published their results in 2010's "Maternal consumption of peanut during pregnancy [4] is associated with peanut sensitization in atopic infants". The work resulted from the collaboration of Scott Sicherer and Hugh Samp...

Black peanut skins as a byproduct from peanut industry contain abundant anthocyanins, evaluated as 8.61±0.27mg/g dry black peanut skins, are currently poorly exploited. In this work, four anthocyanins and three major flavonols were detected and identified by HPLC-PDA-ESI-MS/MS from the acidified water extract of black peanut skins of Arachis hypogaea L. After preliminary removal of flavonols by...

Outbreaks of Salmonella contamination of peanut butter have become a serious food safety concern for consumers. Based on the recent studies on peanut butter storage periods and storage methods, we aim to investigate how temperature and light affect the bacteria growth on generic brands of peanut butter. Our results indicate strong temperature and light effects on bacteria growth and the two mai...

The prevalence of peanut allergy (PA) in Africa is unknown but anecdotal reports suggest the prevalence to be lower than that experienced in developed countries, which report a prevalence of approximately 1.5%. Countries in Africa and Asia, as well as Israel, where the early consumption of high-dose peanut protein is routinely practised, have enjoyed a low prevalence of peanut allergy, e.g. 0.0...

BACKGROUND We previously reported the initial results of the first multicenter, randomized, double-blind, placebo-controlled clinical trial of peanut sublingual immunotherapy (SLIT), observing a favorable safety profile associated with modest clinical and immunologic effects in the first year. OBJECTIVE We sought to provide long-term (3-year) clinical and immunologic outcomes for our peanut S...

Background Peanut oral immunotherapy is both safe and effective in the treatment of children with peanut allergy but study protocols demand large resource commitment, limiting their adoption in routine clinical practice. We present 8 selected peanut allergic children who have achieved either full tolerance or an increased threshold to peanuts following a home based, low dose introduction of pea...

A mixed population of Meloidogyne arenaria race 1 and M. javanica race 3 is reported on peanut from a field in Levy County, Florida. Confirmation of M. javanica on peanut is based on esterase and malate dehydrogenase isozyme patterns resolved on polyacrylamide slab gels following electrophoresis, and perineal patterns. Up to 29% of 290 individual females collected from peanut roots in the field...

Methods In an open study design 460 children aged 5 to 30 months with AE and no detectable peanut-specific serum IgE will be divided into two groups. In Group A parents are advised to feed their children peanut at least three times a week, in Group B participating children strictly avoid peanut in their diet. Children are followed for one year. At the beginning and the end of the study standard...

Results 44 peanut allergic children (median age 5 years) reacted to peanut on DBPCPC with clinical symptoms than ranged from oral allergy syndrome to anaphylaxis. 61% of patients reacted to 0.1g of peanut protein. The mean %CD63+ basophil at 10 and 100 ng/ml of PE was independently associated with severity (p=0.012) whilst CD-sens (1/EC50x100) was independently associated with threshold (p=0.03...
