Vertically acquired community methicillin-resistant Staphylococcus aureus dacryocystitis in a neonate
1Department of Ophthalmology, University of California, San Francisco, San Francisco, California, USA.
Summary
Community-acquired methicillin-resistant Staphylococcus aureus (MRSA) can cause serious infections in newborns. This case highlights MRSA dacryocystitis and periorbital cellulitis with bacteremia in a 12-day-old infant.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Neonatology
Background:
- Community-acquired methicillin-resistant Staphylococcus aureus (MRSA) is increasingly prevalent, particularly in pediatric populations.
- Community MRSA exhibits distinct epidemiology and a broader antibiotic susceptibility compared to hospital-acquired MRSA.
- Ocular and orbital infections are known complications of community MRSA.
Observation:
- A previously healthy, full-term 12-day-old neonate presented with dacryocystitis and periorbital cellulitis.
- The infant had perinatally acquired community MRSA infection.
- Blood cultures confirmed bacteremia associated with the infection.
Findings:
- The neonate was diagnosed with community-acquired MRSA dacryocystitis and periorbital cellulitis.
- Bacteremia was identified as a complication of the localized infection.
- This case represents a severe presentation of community MRSA in a neonate.
Implications:
- Early recognition and treatment of community MRSA are crucial in neonates to prevent severe complications.
- This case underscores the importance of considering MRSA in neonatal orbital and periorbital infections.
- Further research into neonatal MRSA infections is warranted to guide clinical management and public health strategies.

01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
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...
01:25Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
