A bacterial insertion sequence (IS) is a mobile DNA sequence carrying only the transposase gene (tnp) that acts as a mutator to disrupt genes, alter gene expressions, and cause genomic rearrangements. "Canonical" ISs have historically been characterized by their terminal inverted repeats (IRs), which may form a stem-loop structure, and duplications of a short (non-IR) target sequence at both ends, called target site duplications (TSDs). The IS distributions and virulence potentials of Staphylococcus aureus genomes in familial infection cases are unclear...

BACKGROUND: Point-of-care ultrasound (POCUS) is increasingly being used to differentiate cellulitis from abscess in the pediatric emergency department (ED). POCUS has also been shown to decrease length of stay (LOS) for other applications among adult patients. OBJECTIVE: We sought to determine if ED LOS differed for children presenting with skin and soft tissue infections who received POCUS versus radiology-performed ultrasound. METHODS: We performed a retrospective cohort study of children presenting to an urban pediatric ED between January 2011 and June 2013 with a diagnosis of cellulitis or abscess who underwent soft tissue ultrasound...

Older persons (≥65 years) are at risk for invasive group B streptococcal (GBS) infections. The most frequent clinical syndromes in 174 infection episodes were osteoarticular (40%) and skin and soft-tissue infections (30%). In 36% of episodes, a companion microorganism was isolated, and in 45%, blood culture results were positive. Antibiotics were streamlined after species identification in 29% of monomicrobial infections. These findings have clinical and therapeutic implications for GBS infections in the elderly...

Multidrug-resistant (MDR) Escherichia coli have become a major public health concern to both humans and animal health. While the frequency of antimicrobial resistance (AMR) in clinical E. coli is monitored regularly in human medicine, current frequency of AMR in companion animals remains unknown in Australia. In this study we conducted antimicrobial susceptibility testing (AST) and where possible, determined potential risk factors for MDR infection among 883 clinical Escherichia coli isolated from dogs (n=514), cats (n=341) and horses (n=28)...

REVIEW
David P Calfee
Since the first clinical isolate of methicillin-resistant Staphylococcus aureus was described in 1961, this pathogen has established itself as a leading cause of health care-associated infections. More recently, MRSA has become a relatively common cause of infection among persons without typical health care-associated risk factors and is now the most common cause of community-onset purulent skin and soft-tissue infections in many regions of the USA. The appearance of "community-associated" MRSA is not due to the expansion of health care-associated MRSA into the community but rather the result of the independent emergence of a novel clone of MRSA...

PURPOSE: St. John of the Cross (1542-1591) died aged 49 years after 3 months of excruciating pain following a trivial lesion in his right foot. Erysipelas, a superficial bacterial infection of the skin, and subsequent sepsis were previously suggested as the cause of his death. Here, an alternative diagnosis is proposed. METHODS: An accurate perusal of his biography allowed the symptomatology, the clinical evolution, the depth of the infection and the associated systemic manifestations displayed by Fray John to be reconstructed...

BACKGROUND/AIMS: Staphylococcus aureus (S. aureus) infections are a major clinical problem and range from mild skin and soft-tissue infections to severe and even lethal infections such as pneumonia, endocarditis, sepsis, osteomyelitis, and toxic shock syndrome. Toxins that are released from S. aureus mediate many of these effects. Here, we aimed to identify molecular mechanisms how α-toxin, a major S. aureus toxin, induces inflammation. METHODS: Macrophages were isolated from the bone marrow of wildtype and acid sphingomyelinase-deficient mice, stimulated with S...

As the incidence of diabetes continues to increase in the western world, the prevalence of chronic wounds related to this condition continues to be a major focus of wound care research. Additionally, over 50% of chronic wounds exhibit signs and symptoms that are consistent with localized bacterial biofilms underlying severe infections that contribute to tissue destruction, delayed wound-healing and other serious complications. Most current biomedical approaches for advanced wound care aim at providing antimicrobial protection to the open wound together with a matrix scaffold (often collagen-based) to boost reestablishment of the skin tissue...

We present a case of a young girl who presented with multiple cutaneous abscesses over 2 years at different sites. She had no constitutional symptoms or history of tuberculosis. On investigation, she was found to have rifampicin-sensitive tuberculosis presenting as tubercular gumma, a rare form of cutaneous tuberculosis which occurs due to haematogenous spread of the bacilli. She had disseminated disease involving the spinal column with associated psoas abscess. A thorough evaluation was done for immune-deficiency workup but was all negative...

Two types of Klebsiella pneumoniae (KP) strains are currently emerging: hypervirulent (hvKP) strains and carbapenem-resistant (CR-KP) strains. To date, these two strain types rarely overlap. Recent reports, however, suggest that CR-KP strains are increasing in virulence. hvKP strains frequently present as highly invasive infections, such as necrotizing skin and soft tissue infections (NSSTI). To examine whether CR-KP strains with features of hvKP were present in our U.S. hospital, we retrospectively identified four cases of CR-KP NSSTI diagnosed between January 2012 and January 2016...
