Role of childhood adversities and environmental sensitivity in the development of post-traumatic stress disorder in war-exposed Syrian refugee children and adolescents.

Background: Increased post-traumatic stress disorder (PTSD) rates have been documented in children exposed to war. However, the contribution of childhood adversities and environmental sensitivity to children's responses to adversities and trauma are still far from settled.AimsTo evaluate the relative roles of war, childhood adversities and sensitivity in the genesis of PTSD.

The N-acylneuraminate cytidyltransferase gene, neuA, is heterogenous in Legionella pneumophila strains but can be used as a marker for epidemiological typing in the consensus sequence-based typing scheme.

Sequence-based typing (SBT) is the internationally recognized standard method for genotyping Legionella pneumophila. To date all strains of serogroup 1 (SG1) and some of SGs 2 to 14 yield a seven-allele profile and can be assigned a sequence type (ST). However, for some strains belonging to SGs 2 to 14, the targeted region of the neuA gene could not be amplified using the published standard primers.
