UNLABELLED BACKGROUND Successful egg cryopreservation has many potential benefits to a variety of patients. However, a superior standard protocol describing all aspects of oocyte cryopreservation has not yet been identified. Oocyte cryopreservation is still a technical challenge for many infertility clinics. To maintain satisfactory clinical outcomes, there is a need to develop an easy to us...

Cracks in the shell surface compromise the primary barrier for external microbial contamination of the egg. Microcracks are very small cracks in the shell surface that are difficult to detect by human graders. New technology has been developed that uses modified pressure and imaging to detect microcracks in eggs. Research has shown the system to have an accuracy of 99.6% in detecting both crack...

Schistosoma haematobium is a biocarcinogen of human urinary bladder (UB). The present study investigated developing UB cancer mouse model by injecting S. haematobium eggs into the bladder wall and introduction of chemical carcinogens. Histopathological findings showed mild hyperplasia to epithelial vacuolar change, and high grade dysplasia. Squamous metaplasia was observed in the S. haematobium...

Salmonella is the most important human pathogen associated with shell eggs. Salmonella Enteritidis is the serotype most often implicated in outbreaks, although other serotypes have been recovered from eggs and from the commercial shell egg washing environment. Many sample methods are used to recover microorganisms from eggshells and membranes. A shell rinse and modified shell-and-membrane crush...

BACKGROUND Schistosoma mansoni and Schistosoma japonicum are the most frequent causative agents of human intestinal schistosomiasis. Approximately 200 million people in the world are infected with schistosomes. Diagnosis of schistosomiasis is often difficult. High percentages of low level infections are missed in routine fecal smear analysis and current diagnostic methodologies are inadequate t...

Raw eggs are a potential health hazard and a new federally approved process uses ozone to maintain freshness while ensuring safety. The impact of an ozone process on the flavor, color, and shell integrity of eggs must be known for market acceptance. The visual perception and consumer acceptance of full commercial scale ozone-pasteurized eggs are reported, using a degree of liking test and a Jus...

A 54-year-old male Matsigenka native from the Manu jungle of Peru presented with the eggs shown in Figure 1. Kato Katz (Figure 2) testing revealed 1,500 eggs/g stool. The white blood cell count with differential, liver enzymes, and sputum examination were normal. No treatment was administered; however, repeated stool testing was negative. Pseudocapillariasis caused by Capillaria hepatica was di...

Parasite life-history traits reflect past environmental and host selective pressure that act to produce strategies that maximize successful transmission. Pooled human pinworm eggs were pretreated with 0.9% NaCl, acid digestive enzyme, and alkaline solutions (pH 9.0) and then incubated in 0.9% NaCl at room temperature and 37 degrees C both with and without 5% CO2. Eggs pretreated with both acid ...

"Researchers have announced "the first case of human germline genetic modification resulting in normal healthy children." Specifically, the researchers transplanted ooplasm from donor eggs into the eggs of women whose infertility was due to ooplasmic defects. One side effect of those transplants was the transfer of mitochondria, introducing new mitochondrial DNA (mtDNA) into the eggs. This news...

Hereditary pasSage of yellow fever virus through mosquito eggs was first investigated by Marchoux and Simond (1906) who reported successful transmission to a human being through the first generation offspring of an infective mosquito. Rosenau and Goldberger failed to confirm this work; in fact none of thirteen susceptible human beings, bitten by mosquitoes reared from eggs of infected female st...
