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 fungal growths: white with no spore formation, droplets can be seen as possible result of respiration. Read More
While isolating organisms growing in a water system a dark Fungal growth was noted. I love isolating fungi and staining them in a manner that produces contrast among the hyphae. This fungi is yet to be identified but through the lense of a microscope it looks comparable to a tree in the fall a... Read More

The image of Red Lord Ganesha on this MacConkey agar plate is made of Serratia marcescens. It is just an expression that microorganisms are ubiquitous and miraculous in nature just as our gods.
Serratia marcescens produces a blood red pigment called prodigiosin (latin word prodigiosus meaning ... Read More
This artwork is made from Escherechia coli in Mac Conkey Agar ( MCA ) and shows the other side of the biggest Buddhist temple in Indonesia and Southeast Asia built by the Syailendra dynasty called “Borobudur”, that included one of the wonders of the world from Indonesia.
With the Zika virus spreading toward the United States, threatening pregnant mothers and the 2016 Olympics, aid workers have placed hope in a familiar fish.
In the wake of Hurricane Katrina, the Virginia-based non-profit Operation Blessing helped avert an outbreak of the West Nile virus in Ne... Read More
Engineers have developed a rapid, low-cost genetic test for Zika. The $2 device, about the size of a soda can, doesn’t require electricity or technical expertise and only needs a bit of saliva. Read More
Serratia marcescens a Gram (-) rod seen on MaConkey Agar a selective differential agar used to isolate Gram (-) organisms. Culture was grown at 37 degree for 24 hrs, cultures we light pink. The plate was held at room temperature for 24 hrs after that and the majority of Serratia turned red, pr... Read More
Microbes are hardly the poster-children of climate change, but they have far more impact than polar bears on Earth’s carbon cycle – and therefore on our climate. A new study published Friday in Science Advances finds that seabed bacteria and archaea (which look like bacteria but have very differ... Read More
I enjoy having my microbiology students explore their creativity in interesting ways. One approach is to have my micronauts "paint" on Petri dishes using luminous bacteria. In the past, I have inviting people to "vote" on their favorites, and hand out microbiologically themed gifts. This has ... Read More
I had my #Bio350 micronauts write one page "Nanobiographies" of their #MicrobialTermPapers. I'm very pleased. Read More
When I have to explain the organism classification to my students I usually use the one stablished by Woese in the 70s. In this classification, all living things are classified in six kingdoms, that are Eubacteria, Archeobacteria, Protista, Plantae, Fungi and Animalia. All of these groups evolve... Read More
Unknown contaminant, possible Bacillus spp, seen on an old blood agar plate that had been inoculated with Strep bovis. The plate had been incubated at 37 degree's C for 24 hrs then held at room temp for a week. One colony was mucoid with a brain like appearance the other being mucoid and smoo... Read More
This is our way to wish a Happy New Year to all the Microbiologists community!
The numbers were made as follows:
2: E. coli, MacConkey Agar plate incubated at 37 C, 20h.
0,1: MRSA on blood Agar plate, incubated at 37 C + 5%CO2.
7: M. fortuitum on Chocolate Agar plate, incubated at 37 C + 5%... Read More

Montreal, April 28, 2016 - An outbreak of an intestinal parasite common in the tropics, known as Cryptosporidium, has been identified for the first time in the Arctic. The discovery was made in Nunavik, Quebec, by a team from the Research Institute of the McGill University Health Centre (RI-MUHC... Read More
Aedes mosquitoes carrying the bacterium Wolbachia--found inside the cells of 60 percent of all insect species--are drastically less able to transmit Zika virus, say researchers at Brazil's Oswaldo Cruz Foundation (FIOCRUZ) in a study published May 4 in Cell Host & Microbe. Read More
Hospitalization for rotavirus infections decreased by > 70% following the introduction of a vaccine program in Ontario, Canada, according to a study published May 11, 2016 in the open-access journal PLOS ONE by Sarah Wilson from Public Health Ontario and the Institute for Clinical Evaluative Sci...

WASHINGTON — The Senate on Tuesday blocked a $1.1 billion bill to combat the Zika virus, giving Congress just two weeks to try to reach a new deal before lawmakers leave for a seven-week recess in the midst of mosquito season and a growing public health crisis. Read More
Aedes aegypti mosquitoes transmit dengue, chikungunya, and zika viruses. A study published in PLOS NTDs reports a new technique that could make one approach to mosquito control--using Wolbachia bacteria that reduce the mosquitos' ability to transmit viral pathogens--a whole lot easier and che...
