“…The albumen pH was measured using a pH meter (CyberScan 510 pH, Eutech Instruments) on thick and liquid mixtures of albumen. The turbidity of the albumen, the color of the eggshell, and cuticle assessments were measured as previously described (Weijers et al 2006;Francis and Clydesdale 1975;Board and Halls 1973). These qualitative traits of 50 treated eggs and 50 untreated eggs were analyzed immediately.…”

Hot air treatment for surface decontamination of table eggs experimentally infected with Salmonella, Listeria, and Escherichia coli

Hot-air pasteurization was investigated in the EU-funded project "Reducing Egg Susceptibility to Contaminations in Avian Production in Europe (RESCAPE)" as an innovative treatment for surface bacterial decontamination of table eggs. Possible side effects of the treatment on egg quality traits were also studied. The decontamination power of hot air was evaluated over 1 month on shell eggs that were experimentally inoculated with Salmonella enteritidis, Escherichia coli, or Listeria monocytogenes. The S. Enteritidis and L. monocytogenes populations on the surfaces of treated eggs showed a significant reduction compared with untreated eggs. No statistically significant results were obtained comparing E. coli loads on treated and untreated eggs. No detrimental effects on quality traits either immediately after treatment or after 28 days of storage at 20°C were recorded.

“…In most species, the shell surface is covered by a cuticle of protein and carbohydrate, the functions of which are not fully understood (Board 1974). It may repel water, control water loss (Board & Halls 1973), in£uence shell strength or repel microbes (Burley & Vadehra 1989), and shell pigments may play some, as yet unknown, role in one or more of these functions (Solomon 1987;Burley & Vadehra 1989).…”

Although in some cases, such as in ground-nesting species, concentrated spotting of browns, greens and black on a green^brown ground colour clearly provide crypsis, the function of eggshell pigments is not always this obvious.…”

The inheritance of patterns on avian eggshells is central to understanding the evolution of traits such as egg mimicry (e.g. in cuckoos). Yet little is known about the inheritance, or indeed function, of eggshell patterns. It has long been believed that the evolution of eggshell pattern mimicry required that patterns be determined by genes situated on the female-speci¢c W chromosome. However, it has never been demonstrated for any bird that egg pattern traits (rather than ground colour) are female sex linked, or indeed that they are inherited. We studied the inheritance of three measures of egg-pigment patterns in a wild great tit population. Egg patterns were female speci¢c but unrelated to female attributes such as age or condition and showed only weak environmental e¡ects. Eggs of daughters resembled those of both their mothers and maternal grandmothers, but not of their paternal grandmothers. We conclude that this is the ¢rst demonstration of female sex-linked inheritance of avian eggshell patterning, so raising the probability that such a system operates in egg mimics and their hosts.

“…However, even though controlling the flesh is important, it is equally important to suppress the hatching of P. canaliculata eggs [11]- [14]. It is known that the eggshell generally covered by cuticle layer which consists of >85% protein [15] and served as a protection against dehydration and bacterial penetration onto the eggshell [16]- [19]. The application of a commercially available protease has initiated the disruption of this cuticle, thus resulted in the suppression of the hatchability of P. canaliculata eggs, has been previously described [20], [21].…”

Abstract-The application of crude protease of Aspergillus oryzae to suppress the hatchability of Pomacea canaliculata eggs is highlighted. The enzyme was produced through solid state fermentation (SSF) using cassava, which is cheap and abundantly available. It was found that the enzyme suppressed the hatchability of P. canaliculata eggs as much as 30% and 20% at 20.8U/ml enzyme for 3 and 9 days old eggs respectively. The ANOVA result revealed that the hatchability was significantly affected by both protease concentration as well as egg's age. The LC 50 for 3 and 9 days old eggs were 3.29 U/ml and 3.54 U/ml, respectively; while LC 95 for 3 and 9 days old eggs were 19.11 U/ml and 20.09 U/ml respectively. It is proposed that the crude protease propagated from SSF using locally available and cheap material should be considered as an alternative biopesticide to suppress the hatchability of P. canaliculata eggs.
