The key difference between SIR and SEIR model is that SIR is one of the simplest models of epidemiology which has three compartments as susceptible, infected, and recovered, while SEIR is a derivative of SIR which has four compartments as susceptible, exposed, infected and recovered. Epidemiology studies how often diseases occur in different groups of […]
Difference Between Basic and Effective Reproduction Number
The key difference between basic and effective reproduction number is that basic reproduction number (R0) is the reproduction number when there is no immunity from past exposures or vaccination while effective reproduction number (R) is the reproduction number when there is some immunity or some intervention measures in place. Infectious diseases easily spread among populations. […]
Difference Between Spermatic Cord and Inguinal Canal
The key difference between spermatic cord and inguinal canal is that spermatic cord is a collection of vessels, nerves and ducts that run to and from the testes while the inguinal canal is a passage that allows the spermatic cord to pass through. Spermatic cord and inguinal canal are two types of tube-like structures present in the male […]
Difference Between Window Period and Incubation Period
The key difference between window period and incubation period is that window period is the time between infection and the lab test which can identify the infection while incubation period is the period between infection and onset of the disease. An infectious disease is a disease caused by a pathogenic organism such as bacteria, fungus, […]
Difference Between Klebsiella pneumoniae and Streptococcus pneumoniae
The key difference between Klebsiella pneumoniae and Streptococcus pneumoniae is that Klebsiella pneumoniae is gram-negative rod-shaped bacterium while Streptococcus pneumoniae are gram-positive, nonmotile, and nonsporulating oval or spherical shaped bacterium. Both Klebsiella pneumoniae and Streptococcus pneumoniae are two different bacteria that cause pneumonia, and several other types of infections. Both types of bacteria are facultative […]
Difference Between Bacillus and Clostridium
The key difference between Bacillus and Clostridium is that Bacillus is a genus of gram-positive bacteria that grows under aerobic conditions, produces oblong endospores and secretes catalase while Clostridium is a genus of gram-positive bacteria that grows under anaerobic conditions, produces bottle-shaped endospores and does not secrete catalase. Clostridium and Bacillus are two genera belonging […]
Difference Between Azotobacter and Azospirillum
The key difference between Azotobacter and Azospirillum is that Azotobacter is a genus of bacteria that are mainly aerobic and endophytic diazotrophs. Meanwhile, Azospirillum is a genus of plant growth-promoting bacteria that are microaerophilic and surface-colonizing bacteria. Azotobacter and Azospirillum are two bacterial genera that are important as nitrogen fixers in the soil. They are […]
Difference Between CRISPR and Restriction Enzymes
The key difference between CRISPR and restriction enzymes is that CRISPR is a naturally occurring prokaryotic immune defense mechanism that has been recently used for eukaryotic gene editing and modification while restriction enzymes are biological scissors which cleave DNA molecules into smaller substances. Genome editing and gene modification are interesting and innovative fields in genetics […]
Difference Between Plastoquinone and Plastocyanin
The key difference between plastoquinone and plastocyanin is that plastoquinone is a lipophilic carrier molecule that transfers electrons to plastocyanin through cytochrome b6f protein complex. But, plastocyanin is a small water-soluble blue-copper protein that accepts a pair of electrons from the cytochrome b6f complex and passes it to photosystem I in the thylakoid space. Photosynthesis […]
Difference Between Random and Imprinted X Inactivation
The key difference between random and imprinted X inactivation is that random X inactivation is the inactivation of a paternal or maternal X chromosome with equal probability during the time of gastrulation in the epiblast, while imprinted X inactivation is a nonrandom X inactivation of the paternally derived X chromosome in the extraembryonic tissues of […]
