Neonatal sepsis due to group G streptococci

Area of Science:

• Microbiology
• Neonatal Medicine
• Infectious Diseases

Background:

• Group G streptococci (Streptococcus canis) are uncommon pathogens, particularly in pediatric infections.
• Neonatal septicaemia presents a significant challenge in infant healthcare.

Observation:

• Two cases of neonatal septicaemia caused by group G streptococci are presented.
• One neonate experienced concurrent transient neonatal hyperthyroidism.
• The second case involved simultaneous maternal endometritis and neonatal septicaemia.

Findings:

• Bacteria were identified using serological and biochemical techniques.
• Both neonates showed a positive response to penicillin treatment.
• Maternal infection necessitated a combination therapy including penicillin G, gentamicin, and chloramphenicol.

Implications:

• This highlights the potential for group G streptococci to cause severe neonatal infections.
• Increased use of serotyping may lead to more frequent identification of non-group A beta-haemolytic streptococci in infections.
• Effective treatment strategies for both neonates and mothers are crucial.
