Colonies of the anthrax bacterium Bacillus anthracis growing in a culture dish Anthrax is a serious disease that came into public prominence in during the bioterrorism attack in the United States. The name anthrax comes from the Greek word for coal and refers to the black skin lesions it produces. Descriptions of a disease affecting both animals and humans that appear to be anthrax have been found as early as Biblical times, and in fact anthrax has been suggested to have been the fifth plague described in the book of Exodus.

Getty Images Safety breaches at UK labs that handle harmful bacteria, viruses and fungi have spread infections to staff and exposed others to potentially lethal diseases, the Guardian has learned.

One scientist at a PHE laboratory became sick after contracting Shigella, a highly contagious bacterial infection that causes most cases of dysentery in Britain. The incident led the HSE to send the agency an enforcement letter to improve its health and safety practices.

WHO names 12 bacteria that pose the greatest threat to human health Read more The HSE held formal investigations into more than 40 mishaps at specialist laboratories between June and Julyamounting to one every two to three weeks. Beyond the breaches that spread infections were blunders that led to dengue virus — which kills 20, people worldwide each year — being posted by mistake; staff handling potentially lethal bacteria and fungi with inadequate protection; and one occasion where students at the University of the West of England unwittingly studied live meningitis-causing germs which they thought had been killed by heat treatment.

Of the scientists who became infected in the line of work, one was admitted to hospital after falling ill with salmonella poisoning at Pall Life Sciences, a private medical company. Quick guide Show Hide Scientists have had accidents with dangerous bugs for as long as they have studied them.

Brutally honest, often inappropriately candid, a true story….

In the past half century alone, lethal viruses responsible for foot and mouth disease, smallpox, and Sars have all escaped from labs and caused illness or death. The most recent major incident traced to a lab in Britain was the foot and mouth outbreak.

Investigators found that vehicles had carried the virus to farms after driving through mud at Pirbright which had been contaminated by waste from a faulty drainage pipe.

Older mishaps at UK labs cost human lives. Inan assistant at the London School of Hygiene and Tropical Medicine contracted smallpox after the virus was handled on the lab bench. The assistant survived, but infected two people visiting a patient in the neighbouring hospital bed, both of whom died.

InJanet Parker, a medical photographer who worked above the smallpox lab at Birmingham Medical School, became the last recorded person to die from the disease. Investigators concluded that the virus had probably wafted up an internal duct to her room.

Other labs around the world have been blamed for accidental releases of Sars virus. The labs in Singapore, China and Taiwan, had been studying samples from the epidemic which killed more than people when it spread to at least 29 countries.

Despite regular accidents and near-misses at UK germ laboratories, there is rarely any risk to public health because labs have multiple layers of containment, and staff are typically immunised or otherwise protected against the organisms they handle. Thank you for your feedback.

In Britain, microbes that are a risk to human health are ranked by hazard groups. The most harmful are listed in groups 3 and 4. Group 3 bugs, such as those that cause anthrax and leprosy, can pose a serious hazard to employees, and may spread to the community, but there is usually a vaccine or treatment.

Group 4 pathogens, such as Ebola, are more dangerous. These are a serious threat to employees and the community, and there is often no vaccine or treatment. The germs must be handled in labs that meet strict safety and security requirements. The HSE investigated a number of close shaves.

Because the person who packed the material had no idea it contained live dengue, the parcel did not meet safety requirements for posting dangerous agents.

With luck, the package did not leak; it arrived in one piece and was spotted on arrival at the lab, where staff destroyed the material. The sample was improperly labelled and, on arrival, was handled in a way that could have infected the PHE lab worker.

The HSE found failings on both sides. However these cases are in the minority and there was no significant threat to public health. Inthe US Army revealed that its chemical and biological defence facility at Dugway Proving Ground in Utah unwittingly shipped live anthrax to seven countries after failing to kill the spores properly.

One of the batches contained a vial of yet another unsolicited pathogen: Scientists at Dugway spotted the mistake the same day and called ahead to warn the UK authorities, who hastily drew up a plan to move the bugs to a more secure lab for disposal.

Tim Trevan, a former UN weapons inspector who now runs Chrome Biosafety and Biosecurity Consulting in Maryland, said safety breaches are often wrongly explained away as human error.

You have to look deeper and ask: If you do that, you get a better understanding of how things can go wrong. Or what keeps them up at night. These are always good pointers to where, on a proactive basis, you should be addressing things that could go wrong.Infectious Microbes: the Real Culprits Behind Today’s Most Debilitating Chronic Degenerative Diseases A number of cutting edge medical doctors, researchers and scientists have slowly been coming to a startling conclusion: Many of today’s most debilitating and sometimes deadly chronic degenerative diseases for which medical science cannot find an underlying cause, are actually being caused.
