Plague01:24

Plague

Plague is a highly virulent zoonotic disease caused by Yersinia pestis, a Gram-negative, facultatively anaerobic coccobacillus. This pathogen primarily circulates among rodent populations and is transmitted to humans through the bite of infected fleas. Additional transmission routes include direct contact with infected animal tissue or inhalation of respiratory droplets from individuals with pneumonic plague. These multiple transmission pathways highlight the bacterium’s potential for rapid...
Acute Inflammation III: Local and Systemic Effects01:25

Acute Inflammation III: Local and Systemic Effects

Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
Acute Inflammation I: Inflammatory Response01:26

Acute Inflammation I: Inflammatory Response

Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
Acute Inflammation II: Cellular Phase01:26

Acute Inflammation II: Cellular Phase

The cellular phase of acute inflammation is a tightly orchestrated sequence of events that recruits leukocytes, primarily neutrophils, to sites of tissue injury or infection. Following the initial vascular changes, this phase ensures effective immune cell migration, activation, and function at the affected site to eliminate pathogens and initiate tissue repair.Leukocyte Recruitment CascadeLeukocyte recruitment happens in four steps: margination, adhesion, transmigration, and chemotaxis. Reduced...
Rheumatic Heart Disease I: Introduction01:23

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

    Area of Science:

    • Microbiology
    • Immunology
    • Rheumatology

    Background:

    • Yersinia enterocolitica causes acute enteritis and can trigger reactive arthritis in adults.
    • Reactive arthritis is a sterile joint inflammation following infection.
    • The O3 serotype of Yersinia is a common cause of Yersinia-induced reactive arthritis.

    Purpose of the Study:

    • To investigate the prevalence of Yersinia O3 antibodies in patients with reactive arthritis.
    • To compare clinical manifestations between Yersinia-positive and Yersinia-negative reactive arthritis patients.

    Main Methods:

    • Serological testing for Yersinia O3 antibodies in hospitalized patients with reactive arthritis.
    • Comparison of antibody titres between patient and control groups.
    • Analysis of clinical features in relation to antibody status.

    Main Results:

    • A Yersinia O3 antibody titre of 1/160 or higher was detected in 33.7% of 70 patients with reactive arthritis.
    • This prevalence was significantly higher than in the control group (5.8%).
    • Clinical manifestations were examined and compared between Yersinia-positive and Yersinia-negative patient groups.

    Conclusions:

    • Yersinia enterocolitica O3 serotype is frequently associated with reactive arthritis in hospitalized patients.
    • Elevated Yersinia O3 antibody titres support its role as a trigger for reactive arthritis.
    • Further research is needed to elucidate the clinical differences based on Yersinia antibody status.
