Research – Bacteria-killing gel heals itself while healing you

Science Daily

McMaster researchers have developed a novel new gel made entirely from bacteria-killing viruses.

The anti-bacterial gel, which can be targeted to attack specific forms of bacteria, holds promise for numerous beneficial applications in medicine and environmental protection.

Among many possibilities, it could be used as an antibacterial coating for implants and artificial joints, as a sterile growth scaffold for human tissue, or in environmental cleanup operations, says chemical engineer Zeinab Hosseini-Doust.

Her lab, which specializes in developing engineering solutions for infectious disease, grew, extracted and packed together so many of the viruses — called bacteriophages, or simply phages — that they assembled themselves spontaneously into liquid crystals and, with the help of a chemical binder, formed into a gelatin-like substance that can heal itself when cut.

USA – If its not Cyclospora then it must be Hepatitis A – Whats happening in the USA?

Food Poisoning Journal

The Mississippi State Department of Health (MSDH) is investigating a case of hepatitis A in a food service worker that could have led to possible exposure for restaurant customers.

An employee of Los Encinos Mexican Grill (132 W. Main Street) in Calhoun City, MS has been diagnosed with hepatitis A virus, and patrons who ate at the restaurant from July 5 to July 23 might have been exposed.

“The risk of transmission is likely low, but anyone who dined at the restaurant during that time period should consider getting a hepatitis A vaccination from their healthcare provider, pharmacy or any county health department, if they have not been previously immunized” said MSDH State Epidemiologist Dr. Paul Byers.

Research – Norovirus most often responsible for foodborne outbreaks in Finland

Food Safety News norovirus-1080x655

More than 130 foodborne outbreaks were recorded in Finland between 2014 and 2016, according to a recent report.

Data comes from a register of foodborne and waterborne outbreaks maintained by the former Finnish Food Safety Authority (Evira) that became the Finnish Food Authority (Ruokavirasto) at the beginning of this year.

The number of people infected from foodborne pathogens was 2,761 in 132 outbreaks. Forty-eight people needed hospital treatment. No deaths were reported.

Norovirus remained the most common agent in foodborne outbreaks between 2014 and 2016. It was responsible for 42, or 32 percent, of such outbreaks.

USA – Roadhouse 100 Restaurant linked to Hepatitis A problem

Food Poison Journal

According to press reports an employee who handles food at the Roadhouse 100 restaurant on Missouri Highway 100 in the unincorporated community of Gray Summit was diagnosed with hepatitis A, officials with the Missouri Department of Health and Senior Services said Tuesday. Anyone who ate at Roadhouse 100 between June 23 and July 5 is advised to receive the hepatitis A vaccination within 14 days to prevent illness.

The incident is being investigated by the Franklin County Health Department.

A team of investigators has made a key discovery that could make a vaccine for the norovirus a reality.

A study published in the journal Immunity describes how a research team discovered an antibody that is capable of broadly inhibiting several strains of pandemic norovirus.

“In order to design an effective vaccine for norovirus, scientists needed to identify a neutralizing antibody that could work against many strains of the virus, as well as strains that will circulate in the future,” Ralph Baric, PhD, an author on the study, said in a press release. “This information can now be used to build better human vaccines.”

Human noroviruses are the leading cause of acute gastroenteritis and account for nearly 1 in 5 cases of diarrhea and vomiting. Estimates from the US Centers for Disease Control and Prevention indicate that noroviruses cause approximately 200,000 deaths per year, which mostly occur in infants, children, and the elderly.

Although there are more than 30 genotypes of human norovirus, approximately 60% of outbreaks are caused by GII.4 genotype strains, which have caused periodic human pandemics.

The study team comprised investigators from the University of North Carolina at Chapel Hill Gillings School of Global Public Health, University of Texas at Austin, and the National Institutes of Health Vaccine Research Center. The team says that the most important discovery of their research is that a human antibody can bind to a conserved region of the virus that is common in the various strains, potentially neutralizing all GII.4 strains of norovirus that exist in nature.

UK – Belgian alert for Hepatitis A linked to supplements; update to UK outbreak

Food Safety News

Belgian officials have issued a warning because of incidents of hepatitis infections being linked to dietary supplements containing curcumin.

The Federal Agency for the Safety of the Food Chain (FASFC) cited a notification in the Rapid Alert System for Food and Feed (RASFF) detailing cases of acute cholestatic hepatitis following consumption of various dietary supplements containing curcumin.

This alert is not public and the agency has not yet responded to a request for more information from Food Safety News.

Food supplement recalled in Italy

FASFC reported the exact source of contamination was not yet clearly established but was probably due to the presence of curcumin. Curcumin is a substance in turmeric.

The curcumin was used in lot 1810224 of the food supplement “Curcuma Liposomal and poivre noir.” The company Plastimea SA decided to withdraw the product branded Nutrimea from sale. It has an expiration date of October 2021 and was sold between Oct. 23, 2018, and May 24 this year on Amazon France.

Italian authorities first raised the alert in May with two reports of hepatitis. The National Institute of Health (Istituto Superiore di Sanità) in the country reported 21 cases as of June 20.

The number of products affected has grown from two to more than 20 involving firms such as Frama SRL, Scharper S.p.A, Vanatari International GmbH, Ekappa Laboratori S.r.l., and Fidia Farmaceutici S.p.A.

Meanwhile, the number of people with hepatitis A connected with a school in Ripon, a city in North Yorkshire County in England, has increased by two to 19. Reports of new infections connected to Outwood Academy have slowed down during the past week.

Public Health England (PHE) is reviewing data on food eaten in the school canteen to find the source of the outbreak.
