    Insights

    Pasteurella multocida (PM) can cause acute suppurative otitis media in humans, often following animal contact. This case highlights a rare instance of PM-induced ear infection in a nasopharyngeal cancer patient.

    Area of Science:

    • Otolaryngology
    • Infectious Diseases
    • Microbiology

    Background:

    • Pasteurella multocida (PM) is a common bacterium in animals, typically causing gastrointestinal issues.
    • Human infections usually result from animal bites or close contact, leading to wound infections.
    • Acute suppurative otitis media caused by PM is rarely reported.

    Observation:

    • A 45-year-old patient with nasopharyngeal cancer presented with sudden, severe left ear pain and purulent discharge.
    • Physical examination revealed significant yellowish-white purulent secretion in the left ear.
    • Nasopharyngofiberscopy showed extensive purulent secretion in the Eustachian tube and left middle ear.

    Findings:

    • Bacterial culture and drug sensitivity testing identified Pasteurella multocida (PM) as the causative agent.
    • The isolated PM strain was sensitive to multiple antibiotics.
    • The patient was diagnosed with recurrent nasopharyngeal carcinoma and acute suppurative otitis media.

    Implications:

    • This case expands the known clinical manifestations of Pasteurella multocida infections.
    • It underscores the importance of considering unusual pathogens in ear infections, especially in immunocompromised patients.
    • Effective antibiotic treatment, guided by sensitivity testing, led to patient recovery.

    Data Reporting and Recording

    Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

    Microbial Growth Media

    Microbial growth media are essential tools in microbiology, providing the nutrients and conditions necessary to cultivate and study microorganisms. These media are categorized by their composition, consistency, and functional roles, enabling researchers to investigate microbial physiology, behavior, and interactions.Types and Consistencies of Growth MediaGrowth media can be solid, liquid, or semisolid. Solid media, often agar-based, allow visible colony growth for isolation and enumeration.

    Reporter Genes02:11

    Reporter Genes

    Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
