Biology is the branch of science that primarily deals with the structure, function, growth, evolution, and distribution of organisms. It’s a methodological study of life and living things.
Biology is the scientific study of life. It spans multiple levels, from biomolecules and cells to organisms and populations12. All living things share common biological phenomena, such as reproduction, cell division, and the transmission of genetic material.
What is Hafnia alvei ? One species of bacteria that is frequently discovered in both human and animal intestines is Hafnia alvei. Since it is regarded as a commensal bacterium, it usually coexists peacefully with its host, posing no threat to it. A type of facultatively anaerobic Gram-negative bacterium known as H. alvei is frequently […]
Biological Safety Cabinets (BSCs) are critical for ensuring a safe laboratory environment while working with biological agents. They are categorized into three categories: Class I, Class II, and Class III. Each class offers varying degrees of protection for persons, products, and the environment. What is Biological Safety Cabinets (BSCs) ? A Biological Safety Cabinet (BSC)

Biochemical tests are vital for identifying and characterizing bacterial species such as Vibrio cholerae. It is a Gram-negative, comma-shaped bacterium that causes cholera, a serious diarrheal disease. It is commonly found in aquatic habitats such estuaries, rivers, and coastal waterways. The bacteria can infect humans by ingesting contaminated water or food. What is Vibrio cholerae
Bovine Spongiform Encephalopathy (BSE), commonly known as Mad Cow Disease, is a progressive neurological disorder in cattle caused by prions, which are misfolded proteins that can induce other proteins to misfold as well. It was first identified in the United Kingdom in the mid-1980s and subsequently led to a major public health scare due to

What is Enterococcus faecium ? One species of bacteria that is frequently discovered in both human and animal intestines is Enterococcus faecium. Although certain strains pose little threat, others have the potential to infect people, especially those who have recently been hospitalized or have compromised immune systems. Healthcare practitioners should be concerned about E. faecium
Biochemical tests for Streptococcus pneumoniae are laboratory procedures developed to analyze certain biochemical features of this bacterium, assisting in its identification and distinction from other microbes. What is Streptococcus pneumoniae? This often known as pneumococcus, is a Gram-positive bacterium commonly seen in the upper respiratory tract of humans. It is a major human pathogen responsible
What is Kingella kingae ? A picky, facultative anaerobic gram-negative bacterium called Kingella kingae is frequently discovered in the human nasopharynx. Particularly in young children, it is a major cause of osteomyelitis, septic arthritis, and bacteremia. Also, A small bacterium called Kingella kingae is responsible for a number of diseases, most often in infants. It’s
What is Proteus mirabilis ? Proteus mirabilis is the gram-negative, facultative anaerobic bacterium Proteus mirabilis is frequently found in the human gut. It is well-known for its swarming motility and its capacity to produce urease, which is linked to UTIs. The following are common biochemical tests used to identify Proteus mirabilis. Proteus mirabilis is a
What is Pseudomonas aeruginosa ? One frequent opportunistic pathogen that can be discovered with a battery of biochemical assays is pseudomonas aeruginosa. These assays take advantage of the bacterium’s special metabolic properties and offer a trustworthy way to distinguish it from other closely related species. It is typical bacterium that can be found on plants,
Butyric Acid Fermentation is an interesting process that is fueled by some bacteria that decompose carbohydrates without oxygen. The main byproduct of this anaerobic process, which is essential to both human and animal digestive systems, is butyric acid. Anaerobic fermentation of butyric acid occurs when specific bacteria break down carbohydrates, like glucose, into butyric acid,
