However, these can differ between cultivars. The aim current study was to evaluate antioxidant, antimicrobial anti-inflammatory properties three leaves cultivars (Picual, Shemlali Tofahy) commonly cultivated in Egypt. Further...

Seasonal dynamics of Pseudomonas savastanoi pv. savastanoi (Psv) on stems and leaves from symptomless shoots of naturally infected olive trees was monitored in Spanish olive orchards. Data inferred from the comparison between washing of leaves and dilution-plating versus leaf printing of individual leaves suggested that Psv population sizes varied by over several orders of magnitude, among leav...

BACKGROUND The thaumatin-like protein (TLP) Ole e 13 in raw olive fruit is responsible for occupational allergy in olive oil mill workers. However, these workers do not experience allergic symptoms after ingestion of edible olive. OBJECTIVES To analyze the presence of IgE-reactive TLP in raw and edible olive fruit and to assess the allergenic potency of both sources. METHODS The content of ...
