    Insights

    Enteric Gram-negative bacilli are commonly found in the throats of Malaysian adults, but rarely in Australians. These microbes do not appear to cause pharyngitis (sore throat).

    Area of Science:

    • Microbiology
    • Public Health

    Background:

    • Pharyngeal micro-organisms play a role in upper respiratory health.
    • Understanding microbial carriage in different populations is crucial for public health.

    Purpose of the Study:

    • To compare pharyngeal micro-organisms between Australian and Malaysian children and adults.
    • To investigate the prevalence of enteric Gram-negative bacilli in the pharynx.

    Main Methods:

    • Aerobic culture of throat swab specimens from 131 Australian and Malaysian subjects.
    • Comparative analysis of microbial isolation rates across different demographic groups.

    Main Results:

    • Enteric Gram-negative bacilli were frequently isolated from Malaysian adults (28-36%) but rarely from Australian adults (9%).
    • Prevalence in Malaysian children was 12% (with sore throat) and 4% (without sore throat).
    • Microbiological findings were otherwise similar across groups.

    Conclusions:

    • Pharyngeal carriage rates of enteric Gram-negative bacilli vary significantly between populations.
    • These bacilli likely do not play a pathogenic role in pharyngitis.

    Acute Pharyngitis01:30

    Acute Pharyngitis

    Introduction
    Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
    Classification
    Acute pharyngitis can be categorized based on its underlying cause:
    Chronic Pharyngitis01:23

    Chronic Pharyngitis

    Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
    Etiology
    It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
    Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
    The Oral Microbiota01:27

    The Oral Microbiota

    The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
    Microbiota of the Respiratory Tract01:29

    Microbiota of the Respiratory Tract

    The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...

    Microbiota of the Stomach and Small Intestine

    The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...
    Streptococcal Pharyngitis01:27

    Streptococcal Pharyngitis

    Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
