Blood agar/Hemolysis

Three organisms inoculated onto blood agar, straight line inoculation, to demonstrate hemolysis. From top to bottom:
Streptococcus pyogenes: beta, complete lysis of red blood cells, clear area around colony growth.
Streptococcus bovis: alpha, incomplete lysis of red blood cells, green area ... Read More

Eye of Science - Scientific photography

Beautiful scanning electron microscopy images.

"For 2 decades we have been devoting our work to the visualization of the previously unknown and invisible. Detailed, aesthetic, and scientifically correct we present an access into the microscopic world of biology, medicine, chemistry, technolog... Read More

Lyme Disease Bacteria, Borrelia burgdorferi

The Lyme disease spirochete, Borrelia burgdorferi, is an obligate parasite that cycles between ticks and vertebrate hosts. B. burgdorferi alters the proteins expressed on its outer surface, depending on the state of each host. Here, we used immunofluorescent antibodies to identify spirochetes th... Read More

Exoenzyme activity

Ms. Karen Alarcon, 3rd yr - BS Biology student from St. Paul University Quezon City, Philippines is doing an exercise on exoenzyme screening by select bacterial isolates. On the picture, bacteria on starch agar flooded with iodine was analysed for the production of exoenzyme amylase. Read More

Kirby-Bauer disk diffusion

Kirby-Bauer disk diffusion susceptibility test on coagulase-negative Staphylococcus aureus and E.coli grown on Mueller-Hinton agar with tetracycline (30 µg), cephalothin (30 µg), erythromycin (15 µg), chloramphenicol (30 µg), vancomycin (30 µg), penicillin (10 µg), streptomycin (10 µg), and novo...

Assortment in colony biofilms

Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... Read More

Microbe vs. Mineral - A Life and Death Struggle in the Desert

Although the bursts of rainbow colors in this photograph are mesmerizing, microbes fight for their lives in the background. Chemist Michael P. Zach of the University of Wisconsin-Stevens Point, snapped this image of a salt sample he collected in a hot, arid valley near Death Valley National Park... Read More

SIMPLE PHENOTYPIC TEST FOR DETECTION OF METALLO-β-LACTAMASE

This is simlpe phenotypic test which can be done in simple laboratory where molecular technology is not easily avaialble.phenotypic detection of MBL by 0.1mM EDTA.metallo-β-lactamase(MBL )is ambler's class B beta lactamase,which is inhibited by EDTA.this research work was done in our research l...

Nematode Host Meets Bacterial Pathogen

This image shows the nematode host Caenorhbaditis elegans encountering the bacterial pathogen S. marcescens. Natural selection imposed by the co-evolving pathogen led to the evolution and maintenance of bi-parental sex in the host population.

The host and the pathogen were experimentally co-e... Read More

Graphic Warnings: Ebola Posters Keep The Virus On People's Minds

The campaign is called "Kick Back Ebola." But the posters pack a punch.

Sierra Leone has reported over 700 suspected Ebola cases, more than any other country this year. To help stop the outbreak, health workers have put up Ebola awareness signs all over Sierra Leone's seaside capital of Freet... Read More

Lipid Agar

Lipid Plate/Tributyrin Agar used to test for an organisms ability to produce the exoenzyme lipase which breaks down the lipids in the agar creating a clear zone around the organism. (A) Serratia marcesens, lipid hydrolysis, indicated by a zone of clearing around the growing colony, as well as th... Read More
