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

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
Sputum specimen from sick of fibrosis cystic can hold many microbes and yeast. This specimen sent to our laboratory Mycobacteriology of Polyclinic University of Messina for mycobacteria research, shows yeast cells with Ziehl-Neelsen stain. Read More
DNase agar can be used to differentiate between potentially pathogenic S. aureus and other Staphlococcus by looking for the presense of the exoenzyeme DNase. After growth for 24-48 hrs 1N HCL is added to the agar plate. Addition of HCL precipitates DNA in the media causing cloudiness unless t... Read More

Bacteria adjust to wide fluctuations in food supply by controlling how big they get and how often they divide. Scientists at Washington University in St. Louis have just worked out the control system E. coli use to delay division so they can bulk up when food suddently becomes abundant. What can... Read More
