Amphimerus spp. flukes are known to infect mammals, but human infections have not been confirmed. Microscopy of fecal samples from 397 persons from Ecuador revealed Opisthorchiidae eggs in 71 (24%) persons. Light microscopy of adult worms and scanning electron microscopy of eggs were compatible with descriptions of Amphimerus spp. This pathogen was only observed in communities that consumed und...

Salmonella are ubiquitous, host-adapted or zoonotic human and animal pathogens and, after Campylobacter, the genus is the second most predominant bacterial cause of foodborne gastroenteritis Worldwide (Giannella, 1996; Smith, 2003). Numerous foods (meat, seafood, eggs, fresh horticulture, table eggs and poultry) have been associated with Salmonella carriage or contamination (FAO/WHO, 2002; Jay ...

In the oestrous female cat, fertilization can take place when spermatozoa are introduced into the vagina up to 49 hr after an ovulation-inducing injection of human chorionic gonadotrophin. The spermatozoa require residence in the female reproductive tract before they are capable of fertilizing the eggs in vitro. No eggs were fertilized by freshly ejaculated spermatozoa. One of four oestrous fem...

Background Cow’s milk allergy affects about 2-3 % of general population; the prevalence of egg allergy is 1-2% among childhood. According to the literature the development of tolerance for cow’s milk and for egg is reached in early childhood, in the majority of case. In addiction it is reported that over six years of age there is a significant decrease in the resolution rate both for cow’s milk...

Hymenopteran societies are non-clonal. As a result, there is potential conflict among individuals or groups of individuals over reproduction. One area of conflict is male production. In most eusocial Hymenoptera, workers cannot mate but retain functional ovaries. Hence, workers can manipulate their colony's male production simply by laying eggs. Individual workers should gain from causing the c...

Egg specific IgE levels are frequently used in combination with skin-prick tests to guide clinical decisions and to monitor egg allergy evolution in children. We compared both Immulite and ImmunoCAP egg specific IgE assays in egg allergic children, and found a linear correlation between both assays with a mean Immulite:ImmunoCAP ratio of 3. This is relevant information for clinicans wishing to ...

Peptide Microarray Immunoassay (PMI for brevity) is a novel technology that enables researchers to map a large number of proteomic measurements at a peptide level, providing information regarding the relationship between antibody response and clinical sensitivity. PMI studies aim at recognizing antigen-specific antibodies from serum samples and at detecting epitope regions of the protein antige...
