“…GBS are increasingly recognized as virulent human pathogens and 22 human cases of necrotizing fasciitis associated with this organism have been reported in the literature [4,[7][8][9][10][11][12][13][14][15][16][17][18]. Five of these cases occurred in children and three of these were infants aged <12 weeks [7][8][9][10].…”

“…Streptococcus agalactiae, a group B streptococcus (GBS) well known for causing pneumonia, meningitis and sepsis in human neonates [6], has also been reported as a rare cause of monomicrobial necrotizing fasciitis, both in infants and adults [4,[7][8][9][10][11][12][13][14][15][16][17][18]. Whilst S. agalactiae is one of the most important causes of bovine mastitis and has been isolated from other animals including dogs, cats, goats, elephants, fish, and frogs [19][20][21][22][23], there has previously been only two reported cases of GBS necrotizing fasciitis in animals, which occurred in captive bottlenose dolphins [24,25].…”

We observed an outbreak of necrotizing fasciitis associated with Streptococcus agalactiae infection in a group of juvenile saltwater crocodiles (Crocodylus porosus). We undertook screening of crocodiles and the environment to clarify the source of the outbreak and evaluated the isolates cultured from post-mortem specimens with molecular methods to assess clonality and the presence of known group B streptococcal virulence determinants. The isolates were indistinguishable by pulsed-field gel electrophoresis. They were a typical serotype Ia strain with the Calpha-like protein gene, epsilon (or alp1), the mobile genetic elements IS381 ISSag1 and ISSag2, and belonged to multi-locus sequence type (ST) 23. All of these characteristics suggest they were probably of human origin. We review the medical and veterinary literature relating to S. agalactiae necrotizing fasciitis, epidemiology and virulence determinants.

“…Type Ia has increased in prevalence and a corresponding decline has occurred in type II strains causing perinatal disease [143]. Types VI, VII, VIII, and IX rarely cause human disease in the United States or the United Kingdom, but types VI and VIII are the most common serotypes isolated from healthy Japanese women [148,149].

Streptococcus agalactiae, known as a pathogen that causes meningitis and septicemia in neonates, emerges as an invasive organism in nonpregnant adults. This case report describes the fulminant course of a necrotizing fasciitis (NF) with streptococcal toxic shock-like syndrome (STSS) in a 76-year-old diabetic patient caused by S. agalactiae, serotype V. Chronic diseases and immunodeficiency are considered to be risk factors for the acquisition of group B streptococcal disease. Since early surgical treatment in conjunction with antimicrobial and intensive care therapy is critical for the outcome of patients with NF and/or STSS, clinicians should be aware of invasive S. agalactiae infections in adults with subcutaneous emphysema.
