Morphology Of Rodents Rodents (order Rodentia) are the most diverse order of mammals, comprising over 2,200 species and representing nearly 42% of global mammalian biodiversity. They are highly adaptable. to both urban and rural environments, which makes them efficient vectors for transmitting diseases across diverse ecological landscapes. Their morphology is highly adapted for gnawing, with […]

Andes virus spreads mainly through close, prolonged contact with an infected person, not through casual, brief contact. It is the only hantavirus known to have documented person-to-person transmission. Key Takeaways: Andes Virus Quick Guide Person-to-Person Transmission Mechanisms Transmission happens from infected humans, usually during the symptomatic phase, particularly in the prodromal or early clinical stage […]

The HIV Virus Life Cycle involves distinct stages—from cellular binding and integration to replication and maturation. Modern Antiretroviral Therapy (ART) is strategically designed to target these specific viral mechanisms, helping suppress replication and overcome the evolutionary challenges of HIV drug resistance. The HIV life cycle describes how the virus infects CD4 immune cells, replicates using […]

7 Important Structural Differences Between HIV-1 and HIV-2 HIV-1 and HIV-2 are both retroviruses from the lentivirus genus, sharing a similar overall architecture as enveloped, single-stranded RNA viruses but exhibiting key structural differences at genetic, protein, and particle levels; in pathogenicity; transmissibility; and clinical outcomes. HIV-1 is more virulent and globally dominant, while HIV-2 is […]

The HIV virus has a spherical structure about 100 to 120 nm in diameter, featuring a lipid envelope, protein matrix, conical capsid, and internal RNA genome with enzymes. Outer Envelope The envelope derives from the host cell membrane and contains glycoprotein spikes: gp120 (surface unit for host cell attachment) and gp41 (transmembrane unit for fusion). […]

HIV is a virus that infects and progressively weakens the immune system by targeting CD4 cells, while AIDS is the advanced stage of HIV infection when the immune system is severely damaged. Differences Between HIV and AIDS Aspect HIV AIDS Nature Virus (human immunodeficiency virus) that spreads via bodily fluids Syndrome (Acquired Immunodeficiency Syndrome), a […]
