PURPOSE The aim of the study was to investigate immunologic causes of thrombocytopenia in critically ill patients, especially causes that were related to platelet-associated IgG antibodies. SUBJECTS AND METHODS All patients admitted to two intensive care units between May 1 and October 30, 1997, who developed thrombocytopenia (less than 100 x 10(9)(More)
New olive cultivars adapted to Tunisia’s growing conditions were examined for their resistance to verticillium wilt (VWO) to determine whether differences in susceptibility among currently grown cultivars might contribute to the management of this disease. Based on the evaluation of 14 cultivars, 10 were classified as susceptible or extremely susceptible(More)
An actinomycete strain designated TN258, was isolated from Tunisian Sahara soil and selected for its antagonistic activity, especially against Pythium ultimum (P. ultimum) causing potato tubers leak. Based on the results of cultural characteristic of TN258 strain, the 16S rRNA gene nucleotide sequence (1433 bp, accession n° HE600071) and the phylogenetic(More)
Verticillium wilt of olive, caused by the soil-borne fungus Verticillium dahliae, is one of the most serious diseases of olive tree. In this study, a SYBR Green-based quantitative polymerase chain reaction (Q-PCR) assay targeting the intergenic spacer (IGS) region of the ribosomal DNA (rDNA) was developed to quantify V. dahliae microsclerotia (MS) in soils(More)
Dieback and wilting symptoms caused by complex soilborne fungi are nowadays the most serious threatening disease affecting olive trees (Olea europaea) in Tunisia and presumably in many Mediterranean basin countries. Fusarium is one of the important phytopathogenic genera associated with dieback symptoms of olive trees. The objective of the present study was(More)
