The enzymes that make copies of the DNA or RNA genomes of viruses – nucleic acid polymerases – can be placed into two broad categories depending on whether or not they require a primer, a short piece of DNA or RNA, to get going. The structure of the primer-independent RNA polymerase of hepatitis... Read More
“It is exciting that this team were able to validate an ancient traditional remedy,” said Cassandra Quave, an ethnobotanist whose Emory University lab studies the antimicrobial properties of plant compounds. “It demonstrates that traditional medicine—which 80 percent of the world still uses—isn’...

Does the term “microbiome” have dual meanings, an ecological one (BIOME, as in community) and a genomic one (OME, as in genomics)? An interesting blog post. Read More
The fact of using antibiotics in aquaculture has immersed a multiresistance in pathogenic bacteria. This is why a spare solution had to be found which is the probiotics. So for that, I isolated lactic bacteria (lactobacilles) from the intestine of a pelagic fish (sardina pilchardus) and did a lo... Read More
The antibiotic Colistin, which was approved in the 1950's, is now being used as a 'last resort' against multidrug-resistant Gram-negative bacterial infections, despite its nephrotoxic potential. The study, conducted by an international team of NIAID-funded researchers, found that the drug remai... Read More
For humans, Salmonella is always bad news. The bacterial pathogen causes paratyphoid fever, gastroenteritis and typhoid. But for snakes, the bacteria aren’t always bad news. Certain species of Salmonella are a natural part of the snake microbial collective. However, the occasional species can ca... Read More
A dimorphic fungi Exophiala dermatitidis was grown on Saburaud Choramphenicol agar for 3 weeks. After this a sterile polilysine coated coverslip was applied on colony to collect fungal elements. Coverslip was fixed in glutaraldehyde, dried and observed using Hitachi Scanning Electron Microscope.... Read More
One of the immune system's most critical challenges is to differentiate between itself and foreign invaders -- and the number of recognized autoimmune diseases, in which the body attacks itself, is on the rise. But humans are not the only organisms contending with "friendly fire." Read More
The picture was taken for my master thesis in 2005.

This video is presenting some of the most common myths related to "Chickenpox" in the Pakistani society. It's a scene from the daily life showing how people deal with this disease. This video is giving a message to the scientists in particular and society in general why eradication of certain in... Read More
April 17, 2015 - A multicenter team of U.S. and Venezuelan scientists, led by researchers from NYU Langone Medical Center, have discovered the most diverse collection of bodily bacteria yet in humans among an isolated tribe of Yanomami Indians in the remote Amazonian jungles of southern Venezuel...

This was indeed not easy to Google; one of my attempts even had a dr oz page as one of search results. Clearly a dead end. However with some persistence I came up with Entamoeba Histolytica.
A team of French clinicians has diagnosed the first case of rabies in that country since 2003. Only 20 cases of human rabies had been diagnosed in France between 1970 and 2003. Moreover, the patient was unaware of having been bitten. So it is not surprising that that diagnosis was not suggested ... Read More
Calidad microbiológica de las aguas recreacionales, los indicadores de riesgo usados actualmente, y análisis de rastreo de fuente microbiológica; estos son algunos de los temas a discutirse en este episodio de La Radio El Mundo de los Microbios.

Unknown fungal contaminant on TSA after growth at refrigerated temperatures for 1 month. White hypae can be seen at the edges with green spore formation starting in the center. Read More
A broad-based approach is necessary, experts said, because overuse of antibiotics from hospitals to U.S. farms has created a problem that has quickly grown out of control. In January, the Obama administration proposed doubling the government's investment in antibiotic resistance to $1.2 billion.... Read More
A new study published last week in the journal PLOS ONE explores the scope of malaria parasite diversity in southeast African birds, and provides insight into how lifestyle characteristics of birds can influence their association with different parasite genera. Read More
Virus populations do not consist of a single member with a defined nucleic acid sequence, but are dynamic distributions of nonidentical but related members called a quasispecies (illustrated at left). While next-generation sequencing methods have the capability of describing a quasispecies, the ... Read More
