Native and denatured egg white protein IgE tests discriminate hen's egg allergic from egg‐tolerant children

Pediatric Allergy and Immunology, 2015
AbstractBackgroundAccurate diagnosis of egg allergy by IgE testing is challenged by a large number of atopic subjects sensitized, but clinically tolerant to eggs. In addition, discrimination between allergy to raw only, or raw and cooked egg allergy is important.

Nest sanitation elicits egg discrimination in cuckoo hosts

Animal Cognition, 2015
Nest sanitation is a nearly universal behavior in birds, while egg discrimination is a more specific adaptation that has evolved to counter brood parasitism. These two behaviors are closely related with nest sanitation being the ancestral behavior, and it has been hypothesized to constitute a preadaptation for egg discrimination.

Hosts’ Responses to Parasitic Eggs: Which Cues Elicit Hosts’ Egg Discrimination?

Ethology, 2008
AbstractMany hosts of the common cuckoo (Cuculus canorus) exhibit egg recognition, and reject parasitic eggs. How do hosts discriminate cuckoo eggs from their own? Hosts might be able to recognize their own eggs using the specific pigment pattern on the outer eggshell surface, which may serve as a cue for recognition.

How precise is egg discrimination in weaverbirds?

Animal Behaviour, 2002
The village weaverbird, Ploceus cucullatus, lays eggs of an extremely broad range of appearance between individuals. This variation is thought to have evolved as a counteradaptation to brood parasitism by the diederik cuckoo Chrysococcyx caprius. The primary objective of our study was to characterize the relationship between egg appearance and egg ...

Egg recognition and chick discrimination in colonial breeding birds

Behavioural Processes, 2019
Theory predicts that parents will not raise unrelated offsprings. For colonial breeding birds, evolving an ability to recognize their own eggs and chicks can prevent misdirecting parental behaviour. To verify this hypothesis, egg recognition experiments were performed on colonial breeding Chinese pond herons (Ardeola bacchus) and cattle egrets ...

Alien Egg Retrieval in Common Pochard: Do Females Discriminate between Conspecific and Heterospecific Eggs?

Annales Zoologici Fennici, 2009
Incorporation of unrelated eggs into a clutch by incubating females (egg retrieval), which has an obvious adaptive value when female retrieves her own egg, seems to be also a part of the reproductive tactics related to brood parasitism. In open nesting waterfowl, the parasitic egg remains frequently outside the nest bowl after the parasitic event ...

Do Common Whitethroats (Sylvia communis) discriminate against alien eggs?

Journal für Ornithologie, 2003
In a coevolutionary arms race between a brood parasite and its host, both species are expected to evolve adaptations and counteradaptations, such as egg mimicry and egg discrimination. The Common Whitethroat (Sylvia communis) is a regular Common Cuckoo (Cuculus canorus) host in some parts of its breeding range.

Constraints on egg discrimination and cuckoo-host co-evolution

Animal Behaviour, 1995
To understand the co-existence of rejection and acceptance of cuckoo eggs within a host population, the mechanism of egg discrimination and the cost-benefit balance of rejection behaviour were investigated. At a study site in central Japan, rejection rate of cuckoo, Cuculus canorus, eggs by great reed warblers, Acrocephalus arundinaceus, was 61·5%.

Egg discrimination by workers in Diacamma sp. from Japan

Insectes Sociaux, 2011
In eusocial Hymenoptera, workers usually cannot mate but can lay male-destined haploid eggs. In contrast, in many species, worker reproduction is regulated by means of worker policing, which consists of two behavioral categories: aggression towards workers that have developed ovaries, and the destruction of worker-laid eggs.
