Phenotypic test for detection of AmpC β-lactamases.
boronic acid is inhibitor of ampC β-lactamases. result: if zone of inhibition in Cefoxitin(FOX)+Boronic acid(BA) > Cefoxitin(FOX)=5MM.it indicates amp c producer. media :MHA organism: klebisella pneumoniae our resarch work on AmpC β-lactama... Read More
It was my first D-test positive coagulase negative S. aureus isolate during my work on Inducible clindamycin resistance among staphylococci” Read More
For those of us who are normal, non-scientist people, an image of a virus doesn't necessarily hold any meaning. Which floating orb is a healthy cell? And which one is the actual virus? The CGSociety recently invited artists to create renderings of the HIV virus in blood—and the winning images ar... Read More
Researchers have discovered the largest virus ever, and they've given it a terrifying name: Pandoravirus.
A typical virus is a tiny sack of genetic material that injects itself into a much larger cell and uses it to make more viruses. The Pandoravirus is enormous by comparison—large enough to... Read More
The production of Metallo-β-lactamase is one of the resistance mechanisms of Pseudomonas aeruginosa. Metallo-β- lactamases are members of Group B in the molecular classification of Ambler and are Clavulanic acid resistant enzymes which require divalent cations of zinc as co-factors for enzymat...

Pseudomonas aeruginosa is one of the most notorious organisms that have brought the therapeutic dilemmas to clinicians as well as challenge to microbiologist throughout the world. It carries gene of intrinsic resistance (AmpC cephalosporinase, the OprD outer membrane porin, and the multidrug ef... Read More
This isolate was also Methicillin resistant. It was my first D-test positive S. aureus isolate during my work on Inducible clindamycin resistance among staphylococci at Universal College of Medical Sciences and Teaching Hospital, Bhairahawa, Nepal. Read More

One of the most famous pictures of the Vaadhoo Island comes from a night where dots of light seemed to float to the shore. They made the cost look like it was covered in stars.
At night, it is not uncommon for Bio-luminescent microbes called Phytoplankton to be seen along the coast, though even... Read More

This images was taken during the lab work of my Master thesis on Metallo beta lactamase on Pseudomonas aeruginosa and Acinetobacter spps at Shree Birendra Hospital ( Army Hospital) in Kathmandu Nepal . It clearly shows the antagonism between two discs. Read More
Mapping deletion mutations by genetic tools is one thing, seeing them displayed along the length of a DNA molecule is quite another. But how can one see what isn’t there? In 1968, Ronald Davis and Norman Davidson did just that—visualizing deletion mutations in the genome of coliphage l. They rea... Read More
You heard it here first: petri dishes are the new canvases.
When Tel Aviv based physicist and biologist Eshel Ben-Jacob discovered two new strains of bacteria, paenibacillus dendritiformis and the paenibacillus vortex, he also discovered an untapped art form. The bacteria swim outward into sp... Read More
This is a slime mold by the name of Physarum polycephalum. Part of him crept out of the petri dish that had been mistakenly written on with a blue wet erase marker. During growth, I wrap these plates up in foil because the slime mold needs complete darkness to grow. The foil and the humidity ... Read More
phenomenon called "champagne cork"
have waited half year to catch a strain like that. Read More
It's Friday and I can finally enjoy the beach! So I thought it would be nice to reflect my excitement at work growing this happy Listeria monocytogenes ;) Read More
