Summary
This study identified common aerobic bacteria in acute otitis externa (AOE) and their antibiotic sensitivities. Pseudomonas aeruginosa and Staphylococcus aureus were most common, with varying susceptibility patterns to different antibiotics.
Area of Science:
- Microbiology
- Infectious Diseases
- Otolaryngology
Background:
- Acute otitis externa (AOE) is a common infection.
- Understanding the causative aerobic bacteria and their antimicrobial resistance patterns is crucial for effective treatment.
Purpose of the Study:
- To identify and determine the antimicrobial sensitivities of aerobic bacteria in patients diagnosed with acute otitis externa (AOE).
Main Methods:
- Prospective analysis of 66 patients with AOE at a tertiary care center in North India.
- Bacterial culture and sensitivity testing performed on patient samples.
- Analysis of microbiological data from May 2021 to April 2022.
Main Results:
- 50 out of 66 samples showed positive bacterial growth.
- Gram-negative bacteria constituted 60% of isolates, and gram-positive bacteria 40%.
- Pseudomonas aeruginosa (48%) and Staphylococcus aureus (36%) were the predominant pathogens. P. aeruginosa showed high susceptibility to piperacillin-tazobactam and imipenem, while S. aureus was most susceptible to linezolid and doxycycline.
Conclusions:
- Bacterial diversity and evolving antimicrobial resistance necessitate periodic assessment of microbiological flora in AOE.
- Tailoring antibiotic therapy based on local susceptibility patterns is essential for quality and cost-effective patient care.

01:30Acute 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:

01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
01:29Microbiota 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...
