There are many ways of classifying bacteria. One method is based on the cell membrane. In 1884, a bacteriologist named Christian Gram created a test that could determine if a bacterium had a thick, ...

Mouths are filthy, harboring the second largest microbiome of the human body. Some bacteria can help break down food, among other responsibilities; other bacteria can travel into the mouth on food, ...

A recent study has found gut bacteria resistant to common antibiotics (ampicillin and ceftriaxone) in a sizable percentage of healthy birthing moms and their newborns. In this study, 38% of bacterial ...

Researchers have discovered how antibiotic-resistant bacteria construct their defense system -- a finding that could lead to new treatments for currently untreatable infections. Superbugs, also known ...

Cannabidiol (CBD), the main nonpsychoactive ingredient of the cannabis plant, can kill Gram-positive bacteria and, more impressively, Gram-negative bacteria, which excel at antibiotic resistance ...

Gram-negative bacteria deploy a range of protein toxins as mediators of inter-bacterial competition and pathogenicity. Among these, colicins comprise a class of ribosomally synthesised bacteriocins ...

Infectious bacteria are growing increasingly resistant to drugs, which is becoming a serious threat to public health worldwide. Bacteria can be classified based on various characteristics, such as by ...

Gram-negative meningitis is a form of meningitis. The term gram-negative refers to a way of differentiating bacteria. This type of bacteria is typically resistant to drugs and most available ...

In the search for new antibiotics to combat growing drug resistance, Gram-negative bacteria present a daunting challenge. These microbes sport a cell wall and a tight double membrane that create an ...

Gram-positive bacteria show blue or purple after Gram-staining in a laboratory test. They have thick cell walls. Gram-negative bacteria show pink or red on staining and have thin walls. They release ...
