Biology

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.

Biochemical Test of Enterobacter aerogenes

Biochemical Test of Enterobacter aerogenes

Biology /

Enterobacter aerogenes is a Gram-negative, oxidase-negative, catalase-positive rod that is motile and capable of fermenting lactose and glucose (with gas production). It tests positive for Voges-Proskauer and citrate utilization but negative for indole production, methyl red, urease, and hydrogen sulfide production. These biochemical characteristics help distinguish Enterobacter aerogenes from other Enterobacteriaceae. Definition of Enterobacter aerogenes […]

Bile Solubility Test- Principle, Procedure, Types, Results, Uses

Biology /

Bile solubility test is a biochemical experiment used to distinguish Streptococcus pneumoniae from other alpha-hemolytic streptococci. It is based on the idea that bile salts (e.g., sodium deoxycholate) lyse S. pneumoniae cells by activating an autolytic enzyme, while other alpha-hemolytic streptococci are unaffected and remain intact. What is Bile Solubility Test ?  Bile solubility test is

Biochemical Test of Campylobacter fetus subsp. fetus

Biochemical Test of Campylobacter fetus subsp. fetus

Biology /

Biochemical tests are used to identify Campylobacter fetus subsp. fetus by analyzing its metabolic properties. These tests can help differentiate it from other Campylobacter species and subspecies. However, it’s important to note that biochemical tests for C. fetus subsp. fetus have limitations and should ideally be used in conjunction with other methods for definitive identification.

Antigen vs Antibody- Definition and 12 Major Differences

Antigen vs Antibody- Definition and 12 Major Differences

Biology /

The immune system is a complex network of cells and chemicals that work together to protect the body from infection and disease. Antigen and antibody are crucial to this defense process, serving unique but complementary functions. Antigen vs Antibody comparisons highlight the differences between these two critical components. Antigens are foreign molecules, usually proteins or

Biochemical Test of Bordetella pertussis

Biology /

The Gram-negative bacterium Bordetella pertussis is the source of whooping cough, a highly dangerous respiratory illness. It mainly affects newborns and young children and is spread by respiratory droplets. When B. pertussis infects the respiratory system, it causes symptoms like inspiratory whoops, paroxysmal coughing, and post-tussive vomiting. Given the risk of serious consequences, especially in

Biochemical Test of Bifidobacterium bifidum

Biology /

Biochemical Test a widespread Gram-positive, non-motile, anaerobic bacteria in both human and animal digestive tracts is Bifidobacterium bifidum. Many biochemical assays are used to identify Bifidobacterium bifidum, some of which are specific to its special metabolic properties. bifidum, a series of biochemical tests are employed. These tests include Gram staining, which confirms its gram-positive nature,

Biochemical Test of Aeromonas hydrophila

Biochemical Test of Aeromonas hydrophila

Biology /

Aeromonas hydrophila is the rod-shaped, facultatively anaerobic, gram-negative bacterium frequently found in aquatic settings. It is well recognized to infect both people and animals with a wide range of illnesses. The identification and characterization of this bacteria depend on biochemical assays. The main biochemical assays that are used to identify Aeromonas hydrophila are summarized below.
