Health officials have warned pregnant women to avoid travel to the more than 45 countries and territories in which the Zika virus is circulating. Infection during pregnancy can lead to birth defects in infants, particularly brain damage and abnormally small heads, called microcephaly.
But wit... Read More
A surprisingly specific genetic portrait of the ancestor of all living things has been generated by scientists who say that the likeness sheds considerable light on the mystery of how life first emerged on Earth.
This venerable ancestor was a single-cell, bacterium-like organism. But it has a... Read More
The Zika epidemic could be over in three years – but by then up to 93.4 million people may have been infected, including 1.65 million women of childbearing age, and tens of thousands of babies could be affected. But even if the epidemic fizzles out, this could be a temporary relief: a decade lat... Read More
Using novel computational and biochemical approaches, scientists have accurately designed and built from scratch 10 large protein icosahedra -- polyhedra with 20 faces -- similar to viral capsids that carry viral DNA. The designed structures are made of two different engineered proteins, present... Read More
Transmission of Zika virus (ZIKV) was first detected in Colombia in September 2015. As of April 2016, Colombia had reported over 65,000 cases of Zika virus disease (ZVD). We analysed daily surveillance data of ZVD cases reported to the health authorities of San Andres and Girardot, Colombia, bet... Read More

Painting with glowing bacteria. What better way to get students anyone excited about microorganisms? Dr. Mark O. Martin, a self-proclaimed “Microbial Supremacist” uses glowing bacteria to entice students to explore the mysteries of microbiology. Now fellow microbiology educators at ASMCUE creat... Read More
Well you may ask what virus ?
and I tell you West Nile Virus ( but I want to change it to WNV ). Every year when mosquito season arrives it will bring a lot of diseases . one of them is the memory loss. you may ask how does memory loss concern WNV?
Thousands of people are liv... Read More

The latest Zika virus news from the ConTWiVstadors, including a case of female to male transmission, risk of infection at the 2016 summer Olympics, a DNA vaccine, antibody-dependent enhancement by dengue antibodies, and sites of replication in the placenta.
The TWiP ternion solve the case of the Man from Mexico, and discuss a transgenic toxoplasma vaccine for chickens using Eimeria tenella.
Unknown contaminant seen growing on Brain Heart Infusion (BHI) agar plate after several months at refrigerated temperatures, The organism grew at the edge of the agar plate interface, was smooth and circular, cream/beige mat at the base which mounded up, the edges or center of the colony had fi...

Fungal contaminant seen on Bile Esculin Agar (BEA) after several months at refrigerated temperatures. The fungus was circular at the edges with mounding in the center and blackening of the media indicating esculin hydrolysis. Read More
Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is a colorful mucoid orange yeast (possible rhodotorula) slowly overtaking several other colonies (yellow is a presumable yeast as we... Read More
Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is a colorful mix of beige mucoid bacteria, orange and yellow mucoid yeast/bacteria, and white grainy fungi (possible actinomyces?). Read More
Out door wood railing was swabbed onto TSA and grown for 48 hrs at 37 degree's C, then allowed to grow at room temperature for 72 hrs the held at refrigerated temperature for a month. This is a close up of some of the organisms that grew. One was a white circular fungal colony with hyphae, the o... Read More
Swab taken from the lab table top and incubated on TSA for 48 hrs, left at room temperature for 72 hrs then held at refrigerated temperature for a month. Pictured is one of the resulting bacterial/fungal growths (yeast): Circular yellow colony, mucoid, with a donut like appearance

Michael and Vincent present Spotlights, brief reviews of classic papers in the Journal of Bacteriology, and explain how a single bacterial species can reverse autism-like social deficits in the offspring of obese mice.
The anaerobic, Gram-positive Clostridium difficile is a big problem. It causes rampant diarrhea and tissue necrosis, with more than 150,000 annual cases in the United States alone. Many of the disease manifestations of C. difficile are mediated by two exotoxins that C. difficile produces: TcdA a... Read More
