Prevalence of Physician-Reported Food Allergy in Canadian Children.

Background: Food allergy prevalence data have largely been derived from self-report, and estimates vary.

Objective: Determine the prevalence of physician-reported food allergy in children using electronic medical record data from the Canadian Primary Care Sentinel Surveillance Network (CPSSN).

Methods: This was a retrospective cohort study using the CPCSSN repository, Canada's only primary care practice-based surveillance system.

Transcriptome, proteome and draft genome of Euglena gracilis.

Background: Photosynthetic euglenids are major contributors to fresh water ecosystems. Euglena gracilis in particular has noted metabolic flexibility, reflected by an ability to thrive in a range of harsh environments. E.

Evolution of the endomembrane systems of trypanosomatids - conservation and specialisation.

Parasite surfaces support multiple functions required for survival within their hosts, and maintenance and functionality of the surface depends on membrane trafficking. To understand the evolutionary history of trypanosomatid trafficking, where multiple lifestyles and mechanisms of host interactions are known, we examined protein families central to defining intracellular compartments and mediating transport, namely Rabs, SNAREs and RabGAPs, across all available Euglenozoa genomes. Bodonids possess a large trafficking repertoire, which is mainly retained by the group, with extensive losses in other lineages, particularly African trypanosomes and phytomonads.
