Streptococcal toxic shock syndrome (STSS) is a life-threatening disease caused by infection of beta-hemolytic streptococci . Here, we report an uncommon case of STSS with both diffuse peritonitis and necrotizing fasciitis and summarize previous cases. The patient was diagnosed with STSS due to an infection of the soft tissue of the lower extremity after surgery for diffuse peritonitis. The general condition had rapidly deteriorated with multiple organ dysfunction. Immediate intensive care, including mechanical ventilation, hemodiafiltration, and repeated debridement, is indispensable for a favorable outcome...

Staphylococcus aureus is a Gram-positive major human pathogen involved in a wide range of human infectious diseases (from minor skin infections to septicemia, endocarditis or toxic shock syndrome). The treatment of S. aureus infections is very challenging due to the emergence of multiple antibiotic-resistant isolates. The high diversity of clinical symptoms caused by S. aureus depends on the precise expression of numerous virulence factors and stress response pathways, which are tightly regulated at every level (transcriptional, posttranscriptional, translational, and posttranslational)...

Intracameral injection of cefuroxime during phacoemulsification is considered effective in preventing endophthalmitis. Its widespread usage has led to the accumulation of data on local and systemic adverse reactions. The analysis of complications of cataract surgery with cefuroxime injections described in literature has allowed identifying a few different clusters of toxic and allergic reactions to intracameral cefuroxime for the first time. These clusters included toxic anterior segment syndrome, serous retinal detachment with macular edema, retinal hemorrhagic infarction and anaphylactic reaction...

This report presents the relapse and treatment of streptococcal infection in the postpartum period in a patient with severe group A streptococcal sepsis. Maternal sepsis was estimated to cause around 10.7% of maternal deaths worldwide between 2003 and 2009 [1]. Puerperal sepsis caused by group A streptococci (GAS) is associated with 40% of septic deaths among patients with postpartum endometritis, necrotizing fasciitis, and toxic shock syndrome [2,3]. Here we describe a case of recurrent GAS sepsis in the postpartum period...

This study is aimed at detecting and characterizing methicillin-resistant Staphylococcus aureus (MRSA) from bulk tank milk samples of cows, sheep, and goats collected from dairy farms in the Czech Republic. All MRSA isolates were identified using PCR detection of the Staphylococcus aureus-specific fragment SA442 and mecA gene. The staphylococcal chromosomal cassettes mec (SCCmec), spa, and multilocus sequence types (MLST) were determined. The presence of genes encoding enterotoxins (ses), Panton-Valentine leukocidin (pvl), exfoliative toxins A, B (eta, etb), and toxic shock syndrome toxin (tst) were assessed...

Haemophilus influenzae was the main causative organism for acute epiglottitis in the pre- Haemophilus influenzae type b (Hib) vaccine era. However, with current widespread Hib vaccination, the causative organisms may have changed. Here, we report the case of a healthy infant with acute epiglottitis caused by community-acquired methicillin-resistant Staphylococcus aureus (MRSA). The patient was a healthy 17-day-old male infant without a family history of immunodeficiency syndrome. He had not been started on any vaccines...

Group A β-haemolytic Streptococcus or Streptococcus pyogenes is a gram-positive coccus that tends to grow in chains. Streptococcus pyogenes is the cause of many important human diseases, ranging from pharyngitis and mild superficial skin infections to life-threatening systemic diseases. Infections typically begin in the throat or skin. Mild Streptococcus pyogenes infections include pharyngitis (strep throat) and localised skin infections (impetigo). Erysipelas and cellulitis are characterised by multiplication and lateral spread of Streptococcus pyogenes in deep layers of the skin...

Introduction: Sanitary tampons have been in existence for over 60 years. Their use may present certain health risks, potentially associated with an abnormal change of microbial flora in the vagina (e.g., toxic shock syndrome). Tampon production and marketing are regulated differently in different countries. In Australia, Canada and the USA, tampons are classified as Class-II medical devices and their marketing requires pre-clinical and clinical studies, including microbiological trials...

 A patient presenting with fever and purpura after a stay in the tropics tempts a physician to make a differential diagnosis mainly focusing on imported diseases. Although the importance of considering a tropical disease is obvious, the fact that cosmopolitan infections account for one third of the cases in a febrile returning traveler must not be overseen. Toxic Shock Syndrome is amongst the most notorious diseases due to the high mortality when inappropriately managed and the association with necrotizing fasciitis...

Although toxic shock syndrome (TSS) is rare, multiorgan failure can occur without early identification and appropriate therapy. In particular, a few cases of postpartum TSS due to methicillin-resistant Staphylococcus aureus (MRSA) have been reported. Here, we describe a rare case in which a 32-year-old Japanese woman had TSS due to MRSA that was caused by a perineal infection after a normal vaginal delivery. Twelve days after giving birth to a healthy child, she was readmitted to our hospital due to a 2-day fever and perineal pain without uterine tenderness...

Staphylococcus aureus secretes a family of exoproteins structurally homologous to bacterial superantigens, such as toxic shock syndrome toxin-1 (TSST-1), and those exoproteins are thus called staphylococcal superantigen-like proteins (SSLs). Recent studies have revealed that SSLs play roles in evasion of the host defense by disturbing host immune responses. We previously reported that staphylococcal superantigen-like protein 5 (SSL5; a member of the SSL family) inhibited matrix metalloproteinase-9 (MMP-9), which is crucial for leukocyte recruitment to sites of infection...

Streptococcus pyogenes (also referred to as group A streptococci, GAS) causes severe invasive diseases such as bacteremia, necrotizing fasciitis, pneumonia, osteomyelitis, septic arthritis, and toxic shock syndrome in children. However, there are only a few reports on pleural empyema caused by GAS in children. Here, we report the case of a 4-year-old boy who presented with pleural empyema due to GAS after influenza A virus infection. With intravenous antibiotic administration and continuous chest-tube drainage, followed by video-assisted thoracoscopic surgery, his condition improved...

The emergence of a Japan-intrinsic community associated methicillin-resistant Staphylococcus aureus strain (CA-MRSA/J) has been reported. A 70-year-old man with recurrent colon cancer and a history of mitral valve replacement was admitted to the hospital in a state of shock. He was diagnosed with prosthetic valve endocarditis (PVE) caused by MRSA and underwent cardiac surgery. The MRSA isolates belonged to multilocus sequence type 8 and carried staphylococcal cassette chromosome mec IVl and the genes of toxic shock syndrome toxin-1, enterotoxin C, and enterotoxin L...

Iclaprim is a selective bacterial dihydrofolate reductase (DHFR) inhibitor. Although there are alternative options for the treatment of acute bacterial skin and skin structure infections (ABSSSI), iclaprim is differentiated from other available antibiotics. Areas covered: Iclaprim is under clinical development for ABSSSI. This review summarizes the mechanism of action, pharmacokinetics, microbiology, clinical development program, and the differentiation of iclaprim from other antibiotics. Expert commentary: Iclaprim has a different mechanism of action (DHFR inhibitor) compared to most other antibiotics, is active and rapidly bactericidal against Gram-positive pathogens including antibiotic-resistant pathogens, and suppresses bacterial exotoxins (alpha hemolysin, Panton Valentine leukocidin, and toxic shock syndrome toxin-1)...

Streptococcus dysgalactiae subsp. equisimilis (SDSE) causes severe invasive diseases such as streptococcal toxic shock syndrome, similar to that caused by S. pyogenes (GAS). Invasive SDSE infections are increasing, particularly among patients with diabetes mellitus. Here we investigate the association between the pathogenicity of SDSE and diabetes mellitus in a mouse model, using GAS infection for comparison. Intraperitoneal injection of highly hemolytic SDSE-167 into C57BL6/J mice induced a rapid rise in blood glucose concentrations within 4 h, which was otherwise seen only in mice injected with high doses of hypervirulent GAS mutants...

Fulminant staphylococcal infection indicates an explosive, intense, and severe infection occurring in a patient whose previous condition and antecedent would never have caused any anticipation of life-threatening development. This includes necrotizing pneumonia, necrotizing fasciitis, and to some extent toxic shock syndrome and infective endocarditis. In the three former diseases, toxin production plays a major role whereas in the latter (fulminant presentation of infective endocarditis), association with any particular toxinic profile has never been demonstrated...
