The TWiV gang reviews ten fascinating, compelling, and riveting virology stories from 2014.
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
Researchers have created a synthetic DNA analog that can bind to and silence the gene responsible for NDM-1, a severe form of antibiotic resistance that can make ... Read More
Researchers led by the UCLA Fielding School of Public Health examined HIV testing trends among adults ages 50 through 64 both before and after 2006, when the Centers for Disease Control and Prevention (CDC) recommended that most doctors automatically screen all patients for HIV regardless of whe...

Here's an Ebola puzzle for you: If the virus isn't airborne, why do doctors and nurses need to wear full protective suits, with face masks, while treating patients?
After we dug through studies and talked to scientists, the answer slowly emerged.
Ebola does spread through the air. But not ... Read More
Presentation by Anthony S. Fauci, MD, Director, NIAID/NIH, Bethesda, MD, at the ASM Biodefense 2015 Meeting in Washington, D.C. on Feb 11, 2015. Read More
Antibiotic stewardship programs, which promote the appropriate use of antibiotics in hospitals and other healthcare centers, can not only lead to reduction in antibiotic use with no adverse effects but can also lead to significant savings, over $600,000 annually in the case of one New York Ho...

The TWiV team consults an epidemiologist to forecast the future scope of the Ebola virus epidemic in West Africa.
Plant-like microorganisms called algae are pretty interesting little creatures - some species form expansive 'algal blooms' that harm the environment, whereas others can be used to produce biofuel and food sources. Some can even infect humans and mess with their brains.
This diverse organism ... Read More
This is a picture of a Gram stain of an anaerobic blood culture. This pleomorfic bacteria, were Gram negative filamentous bacilli with large round bodies. The identification by MALDI-TOF was Fusobacterium mortiferum. The patient has pancreatitis. I agree if you want to share this picture, since ... Read More
It's well known that antibiotics can disrupt our gut bacteria. But when mosquitoes snack on blood laced with antibiotics, the same can happen to their microbiome. And that depletion of gut bacteria actually increases mosquitoes' susceptibility to the malaria parasite. Meaning they may be more li... Read More
Cryptococcus cells seen with India Ink staining from CSF of an HIV patient in Tanzania. Taken using nothing more than a smartphone camera. The negatively stained capsule is clearly visible, proving that with very simple techniques and a cellphone you can get very clear images of microorganisms Read More

The Picornavirus Overview Video is the first video in our virus package. It introduces the Picornivirus family, covering general characteristics. More detail about each virus within the family is covered in those virus' individual videos. Read More
We can see different biofilms types in liquid medium. In the same order than the picture: Methylobacterium variabile Type Strain / Methylobacterium aquaticum NO00 / Methylobacterium aquaticum NO42 / Methylobacterium aquaticum Type Strain / negative control Read More
Organism seen on handprint, presumably Bacillus sp. Organism grew out from the center with rhizoid growth, lobate edges, tan coloration, glossy throughout the colony, Read More
I took these combined pictures after growing S. aureus ST151 and ST3028 on blood agar plates. Both strains were isolated from cases of subclinical mastitis The plates were incubated at 37 C for 24 or 48 hrs as shown in the picture. ST3028 is one of the novel strains recently identified in ou... Read More
This is as portrait of the late Francis Crick created by my wife Dr. Jennifer Quinn using "paint" of luminous bacteria. Photobacterium leignothi was grown in LB amended to 20g/l NaCl for a few hours until visible luminescence was detected visually. The liquid culture was painted onto amended L... Read More
