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.
Haemophilus aegyptius, commonly referred to as Koch-Weeks bacillus, is a pleomorphic, non-motile, Gram-negative coccobacillus that is mainly linked to acute conjunctivitis, or pink eye. In the lab, identifying this bacteria entails a battery of biochemical assays that take use of its distinct enzymatic and metabolic characteristics. I will go into great depth about these tests […]
Autoimmune diseases refer to a broad category of intricate disorders wherein the immune system, which is meant to defend the body against pathogens and other foreign invaders, inadvertently attacks the body’s tissues. These illnesses can impact different systems and organs, resulting in a broad spectrum of symptoms and medical issues. They are broadly divided into two

Klebsiella pneumoniae is a Gram-negative bacterium which is well-known for causing a variety of illnesses, especially in medical environments. Particularly in those with impaired immune systems, it is a major cause of bloodstream infections, pneumonia, and UTIs. Antibiotic resistance is a well-known trait of K. pneumoniae, which makes treating infections difficult. Its pathogenicity is enhanced
Enterobacteriaceae is a family of bacteria that includes the rod-shaped, gram-negative bacterium Serratia marcescens. It is frequently discovered in soil, water, and the digestive systems of both people and other animals. Human infections caused by Serratia marcescens can include bloodstream infections, wound infections, urinary tract infections, and respiratory tract infections. Numerous biochemical assays may be
Streptococcus canis is a Gram-positive, beta-hemolytic bacterium from Lancefield group G. It is catalase-negative, PYR-negative, and bile esculin-negative. It does not grow in 6.5% NaCl. Streptococcus canis is CAMP test positive, hippurate hydrolysis positive, and typically ferments glucose. These biochemical characteristics help differentiate Streptococcus canis from other Streptococcus species and related bacteria. Definition of Streptococcus
what is Lactobacillus spp.? The term “Lactobacillus spp.” describes a broad category of bacteria that are members of the Lactobacillus genus. Numerous habitats, including the human stomach, mouth, and vagina, are naturally home to these bacteria. Since they are usually regarded as helpful bacteria, they are good for human health. Lactobacillus species A collection of
Haemophilus influenzae is a facultatively anaerobic Gram-negative bacterium that can cause a wide range of illnesses, especially in young infants. In addition to respiratory tract infections, it has been linked to more serious illnesses such meningitis and septicemia. Biochemical tests are used to detect and distinguish Haemophilus influenzae from other germs. The following are some
Edwardsiella tarda is a frequent Gram-negative, facultatively anaerobic bacterium in freshwater and marine environments. It has been reported to infect people and fish on occasion. Biochemical tests are used to identify and distinguish Edwardsiella tarda from other bacteria. The following are some essential biochemical traits and assays for Edwardsiella tarda Edwardsiella tarda Gram Stain Oxidase
What is Gardnerella vaginalis? One kind of bacterium that can live in the vaginal tract is Gardnerella vaginalis. Bacterial vaginosis (BV), a common vaginal infection marked by an imbalance of bacteria in the vagina, is frequently linked to it. Although it is not the only cause of BV, women who have this ailment often have
Neisseria gonorrhoeae is a Gram-negative, oxidase-positive, catalase-positive diplococcus that ferments glucose but not maltose, lactose, or sucrose. It produces a vigorous bubble reaction in the superoxol test and is negative for nitrate reduction, DNA hydrolysis, and butyrate esterase production. These biochemical characteristics help in differentiating it from other Neisseria species and related bacteria. A strong
