Summary
Acinetobacter baumanni endophthalmitis is rare and has poor outcomes. Ciprofloxacin shows 100% sensitivity, making it a potential first-line treatment for this serious eye infection.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Endophthalmitis, a severe intraocular infection, can lead to vision loss.
- Acinetobacter baumanni is an opportunistic pathogen increasingly recognized in healthcare-associated infections.
Observation:
- This study analyzed four cases of Acinetobacter baumanni endophthalmitis in Eastern India (2009-2011).
- Cases were predominantly post-cataract surgery or post-traumatic.
- Acinetobacter baumanni was isolated from vitreous samples in all cases.
Findings:
- All isolates were 100% sensitive to ciprofloxacin but resistant to ceftazidime.
- Visual and anatomical outcomes were generally poor, with one patient achieving 20/200 vision.
Implications:
- Acinetobacter baumanni is a rare but devastating cause of endophthalmitis.
- Ciprofloxacin is a promising first-line intravitreal antibiotic for Acinetobacter baumanni endophthalmitis.
- Early diagnosis and targeted antibiotic therapy are crucial for managing this condition.

Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
Microbiome 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...
Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
