How does Cephalexin work?

Cephalexin slows down and ultimately stops the building of the cell wall that protects the bacteria. Without this protection the bacteria are exposed to outside components which eventually kill it. 

What is the recommended dosage of Cephalexin?

The recommended dosage of Cephalexin for most types of bacterial infection is 250 mg to 1000 mg, taken four times a day for 7 to 14 days. For chronic or more serious infections treatment may have to be continued for a longer period of time. 
The recommended dosage for children depends on their body weight and ranges from 25 mg to 100 mg per kilogram of body weight per day (mg/kg/day). The Cephalexin dose is divided and taken three to four times a day for 7 to 14 days. Children should generally be limited to 4000 mg or less per day.

How long does an average course of Cephalexin last for?

How long Cephalexin needs to be taken for, depends on the severity of the infection, but it should be at least ten days.

There are no sufficient studies on the use of Cephalexin by pregnant women. Therefore, women who are pregnant should not take Cephalexin. Women who are planning on getting pregnant should discuss this with their doctor first. Women who are nursing should also avoid Cephalexin due to the negative effect it can have on a newborn baby.

Can Cephalexin be used for other infections than bacterial ones?

Cephalexin is only effective for the treatment of bacterial infections. It has no effect on viral infections, such as the flu or the common cold.

Lifestyle trumps geography in determining makeup of gut microbiome

Researchers studied the gut microbiomes of wild apes in the Republic of Congo, of captive apes in zoos in the US, and of people from around the world and discovered that lifestyle is more important than geography or even species in determining the makeup of the gut microbiome.

Tiny marine organisms as the key to global cycles

Marine microorganisms play a very important role in global cycles such as of the uptake of carbon dioxide from the atmosphere. However, little is known about how they function. New approaches are for the first time laying the foundation for a more detailed genetic investigation of some key phytoplankton organisms.

Insect wings hold antimicrobial clues for improved medical implants

Some insect wings such as cicada and dragonfly possess nanopillar structures that kill bacteria upon contact. However, to date, the precise mechanisms that cause bacterial death have been unknown. Using a range of advanced imaging tools, functional assays and proteomic analyses, a study by the University of Bristol has identified new ways in which nanopillars can damage bacteria.

Food and Drug Administration has approved mainly important two treatments that are Rogaine and Propecia.
