Gram staining is a type of differential staining used to distinguish between Gram positive and Gram negative bacterial groups, based on inherent differences in their cell wall constituents. Stains ...

Gram-negative bacteria possess an outer membrane that constitutes a formidable barrier to antibiotic penetration. This envelope, embedded with porins and other specialised channels, governs the ...

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 ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria. This ...

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 ...

Urinary tract infections (UTIs) are common, but increasingly hard to treat because the bacteria that cause them are developing resistance to many antibiotics. Researchers headed by a team at the ...

A new drug conjugate tricks Gram-negative bacteria into succumbing to an antibiotic that usually works only against Gram-positive bacteria. Gram-negative bacterial infections are tough to treat ...

• Require X (hemin) and/or V (nicotinamide adenine dinucleotide) factors for growth • Responsible for 0.5–1% of all cases of IE • Haemophilus aphrophilus is the most common species responsible for IE ...

There are two main types of bacteria, and these categories reflect the microbes' biology and their vulnerability to different antibiotics. When you purchase through links on our site, we may earn an ...
