BACKGROUND Hen's egg allergy ranks among the most frequent primary food allergies in children. We aimed to investigate sensitization profiles of egg allergic patients and compare in vitro IgE reactivities of eggs from ancient chicken breeds (Araucana and Maran) with those from conventional laying hen hybrids. METHODOLOGY Egg allergic children (n = 25) were subjected to skin prick test, double...

Indigenous chickens (IC) are mainly raised by resource poor rural households in developing countries [1]. Although they are of low genetic potential compared to the commercial breeds, IC play a vital role in livelihoods of farmers and contribute significantly to food security and income [1]. IC dominates in most smallholder farms in Malawi and they are deemed less productive but appear to be ad...

AIM This research was conducted to evaluate the molluscicidal and mosquitocidal efficacy of silica nanoparticles in the eradication of the larvae and pupa of malaria and filariasis vector as well as vectors of rift-valley fever virus (Culex pipiens); Schistosoma mansoni vector and Biomphlaria alexandrina (snail and egg masses). MATERIALS AND METHODS Hydrophilic nanosilica particles (NSPs) wer...

A blood sample from a patient who returned from Algeria with a fever inoculated on human embryonic lung fibroblasts by the shell vial cell culture technique led to the recovery of Rickettsia prowazekii. The last clinical strain was isolated 30 years ago. Shell vial cell culture is a versatile method that could replace the classic animal and/or embryonated egg inoculation.
