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.

Research -Does physical state of farm housing and milking practices affect total bacteria and somatic cell count of cow milk?

Wiley Online

Abstract

The study determined the effect of physical state of farm housing on total bacteria and somatic cell count (SCC) of cow milk. Milk records collected at Dairy Services Zimbabwe were used. Effects of physical state of ceilings, doors, ventilation, walls, drains, fly‐proofs, windows and roof type on total bacterial count (TBC) in milk, and SCC were determined using general linear models procedure. Poor physical state of ceilings, doors and floors in milking parlors, wash rooms and bulk tank rooms result in high TBC and SCC in milk (p < 0.05). Poor ventilation in the bulk tank room results in high TBC in milk (p < 0.05). Floors, doors, and ceilings of milking houses should be kept in sound condition and good repair in order minimize TBC and SCC in raw milk.

Practical applications

Understanding how physical state of farm houses and management practices affect total bacterial count and somatic cell count in fresh milk enables farmers and regulatory agencies to put in corrective action to reduce bacterial contamination of milk at farm level. This helps keep the population of disease causing bacteria in raw milk, which is widely consumed by human beings, as low as possible. It also helps reduce contamination by some resistant bacteria that might survive processing and cause further defects in milk products. The shelf‐life of the milk and its products is, thus, improved. Reducing bacterial and somatic cell count in raw milk also helps the milk producers to score high milk grades on the market and, thus, fetch high prices.

 

USA – The Village Company Issues Voluntary Nationwide Recall of La Bella Extreme Sport Styling Gel Due to Bacterial Contamination

FDA

On May 24, 2019, The Village Company initiated a voluntary nationwide recall of the 22-ounce La Bella Extreme Sport Styling Gel. Four lots failed micro testing due to bacterial contamination, resulting in potential contamination of 2,377 cases (or 9,508 units). The bacteria found is Burkholderia cepacia and a group of related strains.

Burkholderia cepacia and group of related strains rarely cause infections in healthy people, but pose serious risk to individuals with cystic fibrosis, weakened immune systems, and chronic lung disease. If you are feeling ill after having used the product, consult with your doctor. Washing your hands, hair brush, combs and other hair items, counter tops and other surfaces with warm soapy water are good practices to help prevent the spread of bacteria.

The Village Company has not received any reports from consumers related to this recall. Consumers who have a product from any of the affected lots should stop using it immediately.

The recalled La Bella Extreme Sport Styling Gel was manufactured by Kapra Cosmetics, Inc. (Kapra) and distributed to retail starting March 5, 2019.

The following lot numbers have been recalled:
La Bella Extreme Sport Styling Gel
Lot Numbers: 19057B, 19072C, 19072E, 19072G

Research – Here’s why you really shouldn’t use your phone on the toilet

Sports Yahoo

Germs, germs, germs

For a start the bathroom is a hotbed of germs, which can easily be collected on your digi friend.

Initial Washroom Hygiene swabbed smartphones and found that average reading across all the mobile phones was 1479.

Just to give you an idea of how germ-y this is, a reading of over 500 units from an object indicates a high level of contamination, 200-500 is the normal range, and under 200 is low.

“Our phones are a common reservoir for potentially harmful pathogens and bacteria, and we know that people are prone to using them while visiting the washroom,” explains Dr Colm Moore area technical manager for Initial Washroom Hygiene.

“This is especially alarming when you consider that up to 80% of all infections are transmitted by touch. So when people use their phones and put it in close proximity to their mouths when on calls, they are potentially increasing the likelihood of picking up an illness.”

While many of the pathogens found on phones can be harmless, some can lead to some pretty nasty health ailments.

Research – Your Cutting Board Could Be Making You Sick

Of all the things in the kitchen that could be contaminated, your cutting board probably isn’t the first to come to mind. After all, you wash it after you use it! And it’s a flat surface — so wouldn’t you see any food that stuck behind? But if you don’t know what you’re doing, your cutting board could be exposing you and your family to harmful bacteria.

USA – Kroger Shrimp Recalled For Potential Health Hazard

Food Poisoning Bulletin

Kroger is recalling cooked shrimp that was actually sold raw or undercooked because they could be a potential health hazard. That means the shrimp could be contaminated with spoilage bacteria or with bacteria that could make you sick. The Kroger shrimp was sold in stores in parts of Michigan, central and northwest Ohio, and northwestern Virginia. This recall also includes Fry’s, King Soopers, and Smith’s grocery stores that are part of the Kroger chain.

Research – What’s happening inside your body when you have food poisoning? A new study into Bacillus cereus has some clues

ABC Net

bacillus

You know the symptoms well enough. The clammy chill that washes over your body, the clenching in your stomach and then, finally, the dash to the bathroom, possibly accompanied by a split-second decision about which part of your body to aim at the toilet first.

But what’s happening inside your body when you have food poisoning?

Research published today has given us a slightly clearer idea, at least for one type of bacteria.

A team from the Australian National University looked at the way the body responds to the bacteria Bacillus cereus, which can cause food poisoning and sometimes lead to serious infections elsewhere in the body, including sepsis, pneumonia and meningitis.

They found a toxin secreted by the bacteria binds directly to cells in the human body and punches holes in the cells to kill them, triggering an immune response.
