 #ALT#Bringing Antimicrobial Susceptibility Testing (AST) to the Community
Antimicrobial Susceptibility Testing (AST) is a technique that allows physicians to discriminate between infections caused by drug-sensitive/or resistant bacteria and prescribe the appropriate antibiotic treatment needed for specific patients; but unfortunately, it is mostly practiced in clinical laboratories in hospitals and to less extent at the community level. In this interview, Dr. Ester Segal discusses the development of a 2D silicon microarray on-chip device for rapid diagnostic susceptability testing of bacteria and fungi.

A number of basic procedures must be followed when handling sterile equipment or working in a sterile environment. These include: ensuring that the environment is free from external sources of contamination, such as open windows or doorways and ensuring that any tools or implements to be used have been thoroughly sterilized.
 
 C-di-GMP Signaling in Bacteria
 
C-di-GMP Signaling in BacteriaBis-(3´-5´)-cyclic dimeric guanosine monophosphate (c-di-GMP) is a soluble molecule that functions as a secondary messenger in bacterial cells. One effector of C-di-GMP signaling is RNA, which acts as a riboswitch (an RNA regulatory element that alters the expression profile of the cell).
 
 
 Cervical microbiome may influence HPV infection more than previously thought
 
Infections with a Human Papillomavirus cause 99 percent of cervical cancer cases, and the disease's first sign is often the appearance of precancerous lesions on a woman's cervix. But bacteria may play an important role, too.
