Summary
Group B Streptococcus causes rare neonatal parotitis, presenting as swelling without pus. This finding is crucial for diagnosing late-onset sepsis in infants when Staphylococcus aureus is not the cause.
Area of Science:
- Neonatology
- Infectious Diseases
- Pediatric Otolaryngology
Background:
- Acute neonatal parotitis is typically caused by Staphylococcus aureus.
- Late-onset sepsis in neonates presents a diagnostic challenge.
Observation:
- Two cases of group B streptococcal (Streptococcus agalactiae) acute neonatal parotitis are presented.
- Patients exhibited late-onset infections with acute parotid swelling, lacking cellulitis or purulent Stensen's duct drainage.
- Meningitis was absent in both cases; Streptococcus agalactiae was identified in blood cultures.
Findings:
- Clinical presentation and radiographic findings (parotid swelling, increased vascularization) aided differential diagnosis from cellulitis-adenitis syndrome.
- Intravenous cefotaxime treatment for two weeks resulted in complete recovery for both infants.
Implications:
- Streptococcus agalactiae should be considered in the differential diagnosis of acute neonatal bacterial parotitis.
- Early identification and appropriate antibiotic treatment are vital for managing Streptococcus agalactiae neonatal parotitis and sepsis.

01:27Streptococcal 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...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:28Diphtheria
Diphtheria is an acute, toxin-mediated infectious disease that primarily affects the upper respiratory tract. It is caused by Corynebacterium diphtheriae, a Gram-positive, pleomorphic rod that lacks spore-forming capability and exhibits a characteristic club-shaped morphology under microscopic examination. While C. diphtheriae can asymptomatically colonize mucosal surfaces, clinical disease manifests only when the bacterial strain is lysogenized by a specific β-corynephage. This phage...
01:30Tonsillitis I: Introduction
Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.

01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
