(Re-)Introducing the Pseudomonads. Despite the somewhat murky provenance of their name, pseudomonads are everything but "pseudo-" in terms of their metabolic versatility: they are bacterial omnivores, heterotrophs yet far from picky. Members of the family Pseudomonadaceae (Gammaproteobacteria) a... Read More
Cornell researchers have uncovered details of how the deadly Middle East respiratory syndrome coronavirus (MERS-CoV) enters host cells, findings that help explain how it can infect many cell types – a hallmark of viral pathogenicity. The results also offer possible new avenues for treatment.

The world of lipids does not always gets its due. Their oleaginous charm is not always appreciated, as we said here before. For example, have you heard of hopanoids? They are made by some bacteria and are an unusual kind of polycyclic lipids that resemble steroids, but with an extra ring. Just l... Read More
High-resolution cryo-electron microscopy has now revealed in unprecedented detail the structural changes in the bacterial ribosome which results in resistance to the antibiotic erythromycin.

In the two days since the second U.S. Ebola patient was diagnosed, the U.S. Centers for Disease Control and Prevention (CDC) has assembled a new team to battle the threat of Ebola. This team has no steady lineup, but it will be deployed anywhere in the country that sees a new case of Ebola, CDC ... Read More
Pregnant women have an unusually strong immune response to influenza, an unexpected finding that may explain why they get sicker from the flu than other healthy adults, new research from the Stanford University School of Medicine and Lucile Packard Children's Hospital Stanford has found.
The ... Read More

Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants -- and first acted as energy parasites in those cells before becoming beneficial, according to a new study.

Antibiotic-resistant bacteria can share resources to cause chronic infections, Vanderbilt investigators have discovered. Like the individual members of a gang who might be relatively harmless alone, they turn deadly when they get together with their “friends.”
The findings, reported Oct. 8 in... Read More
In light of the recent emergence of the lethal Ebola virus in the US, the National Science Foundation (NSF) is accepting proposals to conduct non-medical, non-clinical care research that can be used immediately to better understand how to model and understand the spread of Ebo... Read More
Take no chances. Leave no stone unturned. Fueled by Ebola fears, these common axioms are driving policy and action -- at times to hefty measures.
This week, a Central American country closed its borders to anyone who has been anywhere near the disease. And an airline scrambled to inform hundr... Read More
Colonies of candida species:
Media: HiCrome Candida Differential Agar
principle: Perry and Miller (1) reported that Candida albicans produces an enzyme b -N-acetyl- galactosaminidase and according to
Rousselle et al (2) incorporation of chromogenic or fluorogenic hexosaminidase substrates... Read More
Extreme adaptations of species often cause such significant changes that their evolutionary history is difficult to reconstruct. Zoologists have now discovered a new parasite species that represents the missing link between fungi and an extreme group of parasites. Researchers are now able to und... Read More
Studying chromosome organization in bacteria. Over the last twenty years, molecular biologists developed and refined a downright cute method to study bacterial chromosome organization in live cells. Briefly, a cluster of binding sites for a DNA-binding protein is introduced at a chosen locus of ... Read More
McMaster scientists have found that an anticonvulsant drug may help in developing a new class of antibiotics.
Although dozens of antibiotics target what bacteria do, their study has looked at how a certain part of bacteria are created, and they found there is a way of stopping it.
The disc... Read More
Tara Smith joins the TWiEBOVsters to discuss the Ebola virus outbreak in west Africa, spread of the disease to and within the US, transmission of the virus, and much more.
New research into a rare pathogen has shown how a unique evolutionary trait allows it to infect even the healthiest of hosts through a smart solution to the body’s immune response against it.
Scientists at the University of Birmingham have explained how a particular strain of a fungus, Crypto... Read More
Brazilian researchers in Rio de Janeiro have released thousands of mosquitoes infected with bacteria that suppress dengue fever.
The hope is they will multiply, breed and become the majority of mosquitoes, thus reducing cases of the disease.
The initiative is part of a programme also takin... Read More
We have lived with the discovery of small RNAs as regulatory molecules for nearly 30 years, so for most readers of this blog this is old hat. But some of us oldsters are still reeling from the novelty and importance of the findings. It seems odd that a subject of this significance, one that has ... Read More
The first case of Ebola in the United States was announced today, with a patient in Dallas who traveled to the US from Liberia. The resultant hysteria and xenophobia prompts this reminder. There is NO need to panic.
Ebola is NOT transmitted before a patient develops symptoms. Ebola is transmi... Read More
