Opportunistic Infections: Definition, etiopathogenesis, clinical manifestations, non-pharmacological and pharmacological management
ByDeepak Rajput February 26, 2024February 26, 2024

Opportunistic infections (OIs) are infections caused by pathogens that typically do not cause disease in individuals with intact immune systems but can exploit weakened immunity, as seen in conditions such as HIV/AIDS, immunosuppressive therapies, or certain medical conditions. Opportunistic infections can affect various organs and systems, leading to severe and potentially life-threatening complications. Etiopathogenesis 1….

HIV (Human Immunodeficiency Virus): Definition, etiopathogenesis, clinical manifestations, non-pharmacological and pharmacological management
ByDeepak Rajput February 26, 2024February 26, 2024

HIV is a retrovirus that attacks the immune system, specifically the CD4 cells (T cells), which play a crucial role in the body’s defense mechanism. The virus can lead to the progressive failure of the immune system and, if untreated, can result in acquired immunodeficiency syndrome (AIDS). Etiopathogenesis 1. Transmission: HIV is primarily transmitted through…

Urinary Tract Infections (UTIs): Definition, Etiopathogenesis etc
ByDeepak Rajput February 26, 2024November 13, 2025

Urinary tract infections (UTIs) are microbial infections that affect any part of the urinary system, including the kidneys, bladder, ureters, and urethra. They are commonly caused by bacteria, but viruses and fungi can also be responsible. UTIs can be categorized as lower (cystitis, urethritis) or upper (pyelonephritis) depending on the involved anatomical structures. Etiopathogenesis 1….

Mechanism of Action of Enzymes
ByDeepak Rajput February 25, 2024February 25, 2024

Enzymes play a fundamental role in catalyzing biochemical reactions within living organisms. The mechanism of enzyme action involves a series of steps that facilitate the conversion of substrate molecules into products. This process can be elucidated through the lock-and-key model and the induced-fit model, providing insights into substrate binding, catalysis, and product release. 1. Substrate…
