• Quantities of experimental Ebola drug used in U.S. too small to be shipped to West Africa

    Nigerian health authorities said yesterday that West African patients infected with the Ebola virus will not have access to experimental drugs being used to treat American cases of the disease for several months, if at all. Health minister Onyebuchi Chukwu told a press conference he had asked the U.S. health authorities about the unproven medicines used on two American doctors who became infected while treating patients in Liberia, but was told such small quantities of the drug existed that West Africa would have to wait for months for supplies, even if they were proved safe and effective. The two Americans were given the drug ZMapp after being flown to the United States, and appear to be recovering.

  • Forensic technology detects drugs in milk, meat

    TV shows like “CSI” have made forensics a hot topic, spawning books and even science programs for kids. The same technology used at crime scenes to link a stray hair to a suspect can also find antibiotics or other medications in milk and meat. And the use of sophisticated testing is becoming increasingly available for livestock producers, who stand to lose lots of money if their products are tainted.

  • Ebola outbreak could inspire African terrorist groups to weaponize the virus: Experts

    Recent discussions about Ebola have mainly focused on the disease as a public health hazard, but counterterrorism officials are concerned that the new outbreak could inspire terror groups, specifically those based in West Africa, to weaponize the virus. The fear of weaponized Ebola dates back decades to when the Soviet Union’s VECTOR program, aimed at researching biotechnology and virology, was thought to have researched the creation of Ebola for warfare. In 1992 a Japanese cult group called Aum Shinrikyo tried, but failed, to collect samples of the Ebola virus in Zaire.

  • Luminex’s diagnostics tool used in Africa to help control Ebola outbreak

    Luminex said the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) Diagnostics Division is working on rapid diagnostics for the Ebola virus using Luminex xMAP Technology. Luminex’s MAGPIX system was recently deployed to Africa to support research efforts to control the current outbreak.

  • U.S., European doctors, health worker rush to Africa to fight Ebola outbreak

    Foreign health workers and medical staff are traveling to West Africa to help communities battle the deadliest Ebola outbreak on record. More than sixty local medical staff who treated Ebola patients, roughly 8 percent of the fatalities, have died in Sierra Leone, Liberia, and Guinea. Dr. Tom Frieden, head of the Centers for Disease Control and Prevention(CDC), announced that the United States will send fifty public health officials to West Africa in the next thirty days to help fight the disease.

  • New technology could screen for emerging viral diseases

    Researchers developed a microbe detection array technology which could provide a new rapid method for public health authorities to conduct surveillance for emerging viral diseases. With the use of the Lawrence Livermore Microbial Detection Array (LLMDA), combined with a DNA amplification technique developed by researchers from Denmark, the team was able correctly to identify twenty-nine different emerging viruses in both clinical and non-clinical samples.

  • Toledo’s water alarm harbinger of things to come

    This past weekend, officials in Toledo, Ohio urged residents and the several hundred thousand people served by the city’s water utility not to drink tap water after discovering elevated levels of microcystin, a toxin caused by algal blooms, in their water supply. Toledo’s water supply has since returned to normal, but nutrient enrichment and climate change are causing an apparent increase in the toxicity of some algal blooms in freshwater lakes and estuaries around the world, scientists say.

  • Ebola outbreak is cause for concern but there’s hope yet

    The current outbreak of Ebola in West Africa is now the largest recorded since the virus was first described in 1976. That this outbreak is not under control after more than four months is cause for great concern, as are the way the virus is spreading and apparent breaches in infection control. The epidemic was recognized at the outset as being unusual. It started in a region that borders Guinea, Sierra Leone and Liberia, far from where previous outbreaks had been reported. And cases spread early to a number of areas in all three countries. There are also some positive signs. Because the incubation period (the delay between contact and becoming unwell) is up to twenty-one days, current infections represent the state of control measures over that period. So the results of more recent control efforts are yet to be reflected in case numbers. The good news is that it does appear the outbreak is coming under control in some areas, particularly in Guinea where the first cases were reported.

  • 2nd Ebola death in Nigeria; Liberia orders cremation of victims

    Nigerian authorities today (Monday) confirmed a second case of Ebola in Africa’s most populous nation, an alarming setback as officials across the region are desperately trying to contain the spread of a disease. Also Monday, health authorities in Liberia ordered that all those who die from Ebola be cremated after communities opposed having the bodies buried nearby. Over the weekend, health authorities in the West African country encountered resistance while trying to bury twenty-two bodies in Johnsonville, outside the capital Monrovia. Military police helped restore order.

  • Airports scrambling to find effective passenger Ebola screening methods

    Some airports in Africa have begun screening passengers for Ebola. The current methods involves thermal screening of patients, and then subjecting passengers with an elevated temperature, a symptom of Ebola, to a blood testcalled a polymerase chain reaction test. The test can take eight hours or longer to obtain lab results, and is expensive.Aviation experts recommend screening passengers for Ebola the same way aviation security screen passengers for other threats like terrorism, but say the screening methods must be made to yield results more quickly and cheaply.

  • Scientists support research which increases microbes’ virulence, transmissibility, or host range

    Amid new concerns about lab safety lapses and in a counterpoint to recent calls for restrictions on research that may render pathogens more dangerous, thirty-six scientists from several countries have issued a formal statement asserting that research on potentially dangerous pathogens can be done safely, and is necessary for a full understanding of infectious diseases. The statement rejects calls for limiting “gain-of-function” (GOF) research, that is, experiments which involve increasing the virulence, transmissibility, or host range of microbes.

  • West African countries intensify efforts to contain Ebola outbreak

    Togo-based, pan-African airline ASKY has suspended all flights to and from the capitals of Liberia and Sierra Leone, and growing fears of the rapidly spreading Ebola virus have led the Liberian football association to cancel games. Liberia plans to shut down schools and many markets, place all non-essential public servants on leave and quarantine several communities. The rural communities which will be guaranteed will have food supplies and medical support ferried only by approved persons. All public facilities could be chlorinated and disinfected on Friday, and public gatherings have already been banned.

  • New methods of detecting Salmonella in pork meat processing

    Infections caused by foodborne microorganisms are an increasing public health burden. In a Ph.D. project at the National Food Institute, Technical University of Denmark, new methods of characterizing and detecting foodborne illness-causing Salmonella in pork meat processing and in bacteria in water, feed and food samples were studied.

  • What you need to know about Ebola

    More West African nations are alerting health officials and citizens about the potential for the deadly Ebola disease to spread by individuals traveling from Guinea, Liberia, and Sierra Leone, where more than 700 people have died in recent weeks.An American doctor, Kent Brantly, working in Monrovia, Liberia with Ebola patients has contracted the disease.

  • Clay minerals may offer an answer to MRSA, other superbug infections

    Researchers set out to identify naturally occurring antibacterial clays effective at killing antibiotic-resistant bacteria. They incubated the pathogens Escherichia coli and Staphylococcus epidermidis, which breeds skin infections, with clays from volcanic deposit near Crater Lake, Oregon. They found that the clays’ rapid uptake of iron impaired bacterial metabolism. Cells were flooded with excess iron, which overwhelmed iron storage proteins and killed the bacteria.
