Following Maternal Transmission, Group B Strep Mutates to Sicken Infants

Washington, DC - August 18, 2015 - Group B streptococcus, a mostly benign inhabitant of healthy adults, is one of the world’s leading causes of neonatal sepsis and meningitis. A team of French investigators has now shown that such cases might occur when the microbe mutates within the infant foll... Read More

8th grader petri dishes - seeking help to identify colonies

I did a study of hand washing and hand sanitizer. Is anyone on the list willing to help me identify what grew from my unwashed and even washed hands? I attach three photos representing the yellow, white and orange growths found after several days on agar plates. Thank you so much in advance. Read More

High containment: inside the £145M virus lab

Ever wondered what considerations go into a brand new £145M virus research laboratory? The new award-winning building at The Pirbright Institute has taken some brave and bold steps in design to contain high-risk microbes. High containment labs are usually buried deep inside a building to keep da... Read More

Decontamination Exterminates Antibiotic Resistant Bacteria from Pig Farm

Washington, DC – September 4, 2015 - Decontamination protocols eradicated both methicillin-resistant Staphylococcus aureus (MRSA) and antibiotic resistant, pathogenic intestinal bacteria, the Enterobacteriaceae, from a pig farm. The research appears online September 4th in ASM’s journal Applied ... Read More

NIH-funded study establishes genomic data set on Lassa virus

An international team of researchers has developed the largest genomic data set in the world on Lassa virus (LASV). The new genomic catalog contains nearly 200 viral genomes collected from patient samples in Sierra Leone and Nigeria, as well as field samples from the major animal reservoir, or h... Read More

Gerilizumab IL-6 is Put into Human Trial for Rheumatoid Arthritis

BOC Sciences-Recently, a biotechnology company announced that gerilizumab IL-6 as a drug for rheumatoid arthritis was under trial in healthy people. Once the safety is proved in human trial, gerilizumab will be a better alternative for rheumatoid arthritis both in effect and cost. Read More

'Clever adaptation' allows yeast infection fungus to evade immune system attack

Johns Hopkins Bloomberg School of Public Health researchers say they have discovered a new way that the most prevalent disease-causing fungus can thwart immune system attacks. Read More

Tripped up by a bug: Infection may cause falls, especially in older people, study suggests

SAN DIEGO - People who end up in the emergency room because of a fall often are tripped up by an infection, rather than a loose throw rug or poor eyesight, suggests a study being presented at IDWeek 2015™. Read More

Viral variation in single cells

It is well known that virus populations display phenomenal diversity. Virus populations are dynamic distributions of nonidentical but related members called a quasispecies. This diversity is restricted in single cells, but is restored within two infectious cycles. Read More

Ebola crisis provides framework for responding to outbreaks like Zika virus

PRINCETON, N.J.--As world leaders grapple with containing the Zika virus, the Ebola epidemic in West Africa provides valuable lessons for how to respond to infectious disease epidemics, according to a policy report published by researchers at Princeton University and the Wellcome Trust. Read More

Molecular 'kiss of death' flags pathogens

DURHAM, N.C. -- Many bugs that make us sick -- bacteria, viruses, fungi and parasites -- hide out in our cells in protective little bubbles called vacuoles. To clear an infection, the immune system must recognize and destroy these vacuoles while leaving the rest of the living cell intact. Read More

Flu vaccine reduces hospitalizations and deaths among nursing home residents

When the influenza vaccine is well matched to the prevailing strains of flu in a given season, patients in nursing homes are significantly less likely to be hospitalized or to die of pneumonia and other influenza related causes. The finding comes from a study of more than 1 million Medicare fee-... Read More

Portraits of Microbiologists Using Luminous Bacteria as "Paint."

My wife Jennifer Quinn​ hits it out the park: a portrait of Kenneth Nealson​ and the late Woody Hastings "painted" with luminous bacteria, giving them props for the early days of quorum sensing---where the basic principles were first uncovered in bioluminescent microbes. This principle of "aut... Read More

Notch Inhibitors are Potential for Cancer Treatment Studies Found

BOC Sciences-Notch inhibitors like gamma-secretase inhibitors (GSIs) are found potential to slow the deterioration of various types of cancer recent studies revealed. Now further study for more accurate information about this application is undergoing, in which different cancer types are involve... Read More

Nobel Prize in Physiology or Medicine was Shared by Three Scientists

BOC Sciences-The three scientists who were awarded for the Noble Prize in Physiology or Medicine were all born in the 30’s of last century. They made the breakthrough both in their own scientific career and on the way of drug development for the whole humankind partly because of the spirit of pe... Read More

Role of breast cell infection in flu transmission between mothers and breast-feeding ferrets

Influenza is known as an infectious respiratory disease, but a study published on October 8th in PLOS Pathogens suggests that infected cells in breast tissues could play a role in virus transmission from mothers to breast-feeding infants and vice versa using a ferret model. Read More

Hibernating bats mount a partial immune response against white nose fungus

White-nose syndrome (WNS), an invasive skin infection caused by the Pseudogymnoascus destructans (Pd) fungus has killed millions of bats since it was first seen in North America in 2007. A analysis of gene expression in hibernating bats infected with the destructive fungus published on October 1... Read More

Wibbly-wobbly-timey-wimey

A Time Lord needs his TARDIS to embark on fantastic discoveries. These LB agar plates contain a colorless reagent called X-gal, which is the sugar galactose linked to a dark blue dye. Some microbes can synthesize an enzyme (β-galactosidase) that snips the X-gal in two, releasing the blue color a... Read More

HIV cure research: NIH scientists create 2-headed protein to deplete HIV reservoir

Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-... Read More
