The key difference between strep and staph infection is that strep infection is a bacterial infection caused due to Streptococcus bacteria, while staph infection is a bacterial infection caused due to Staphylococcus bacteria. Bacteria are single-cell organisms. Most bacteria are not harmful. But some bacteria cause infections. Bacterial infections can affect the skin, throat, lung, […]

The key difference between Vibrio cholerae and Vibrio parahaemolyticus is that V. cholerae is a food-borne pathogenic bacterium that causes cholera in humans while V. parahaemolyticus is a food-borne pathogenic bacterium that causes acute gastroenteritis in humans. Vibrio is a genus of gram-negative curved rod-shaped bacteria found in marine environments. This genus consists of many […]

The key difference between green and purple sulfur bacteria is that green sulfur bacteria are a group of sulphur bacteria that appear in yellow-green, green-orange or brown colour while purple sulphur bacteria are a group of proteobacteria that appear in a purple or reddish-brown colour. Cyanobacteria are a group of bacteria that can do photosynthesis. […]

The key difference between Haemophilus influenzae and Haemophilus parainfluenzae is that Haemophilus influenzae is a gammaproteobacterium that requires both hermin (factor X) and NAD+ (factor V) for its growth, while Haemophilus parainfluenzae is a gammaproteobacterium that requires only NAD+ (factor V) for its growth. Haemophilus is a genus of gram-negative, pleomorphic and coccobacilli bacteria. This […]

The key difference between PCV13 and PPSV23 is that PCV13 (13-valent pneumococcal conjugate vaccine) is a vaccine against pneumonia that contains 13 antigens from common serotypes, while PPSV23 (23-valent pneumococcal polysaccharide vaccine) is a vaccine against pneumonia that contains 23 antigens from common serotypes. Pneumonia is a respiratory disease that causes significant morbidity and mortality […]

The key difference between Neisseria and Moraxella is that Neisseria is a genus that belongs to the class of beta proteobacteria while Moraxella is a genus that belongs to the class of gamma proteobacteria. Proteobacteria is a major phylum comprised of gram-negative bacteria. This phylum consists of a wide variety of pathogenic genera such as […]

The key difference between apterygota and pterygota is that apterygota is a subclass of insects comprised of wingless insects, while pterygota is a subclass of insects comprised of winged insects. Insects are the largest group within the arthropod phylum. They are also the most diverse group of animals. Generally, an insect has a chitinous exoskeleton, […]

The key difference between Mycobacterium tuberculosis and Mycobacterium bovis is that Mycobacterium tuberculosis infects only humans while Mycobacterium bovis infects both humans and domestic animals. Mycobacterium tuberculosis and Mycobacterium bovis are two species classified under the genus Mycobacterium. Mycobacterium is a genus of Actinobacteria. There are over 190 species in this genus. Some species of […]

The key difference between Schizophyta and Cyanophyta is that Schizophyta is an old group in classification that consists of two classes as Schizomycetes (bacteria) and Myxophyceae (blue green algae) while Cyanophyta is a new group in classification that consists of only Myxophyceae (blue green algae). Bacteria and cyanobacteria are two groups of prokaryotic organisms. Most […]

The key difference between Bacillus subtilis and Bacillus cereus is that Bacillus subtilis is fermenting mannitol, but it lacks the ability to produce enzyme lecithinase while Bacillus cereus is not fermenting mannitol, but it produces enzyme lecithinase. Bacillus is a genus of gram-positive, rod-shaped bacteria. They are members of phylum Firmicutes. There are 266 named […]
