Microorganisms continuously monitor their surroundings and adaptively respond to environmental cues. One way to cope with various stress-related situations is through the activation of the stringent stress response pathway. In Pseudomonas aeruginosa this pathway is controlled and coordinated by the activity of the RelA and SpoT enzymes that metabolize the small nucleotide secondary messenger molecule (p)ppGpp. Intracellular ppGpp concentrations are crucial in mediating adaptive responses and virulence. Targeting this cellular stress response has recently been the focus of an alternative approach to fight antibiotic resistant bacteria...

Background: Staphylococcus aureus colonization poses risk for subsequent skin and soft tissue infection (SSTI). We hypothesized that including systemic antibiotics in the management of S. aureus SSTI, in conjunction with incision and drainage, would reduce S. aureus colonization and incidence of recurrent infection. Methods: We prospectively evaluated 383 children with S. aureus SSTI requiring incision and drainage and S. aureus colonization in the anterior nares, axillae, or inguinal folds at baseline screening...

Staphylococcus aureus infections affecting the skin and soft tissues are of significant health concern and an unmet need to be addressed. The lack of drug penetration into the infectious site is the main clinical challenge. Once the pathogen invades the wounded skin, it attenuates biological response pathways, leading to chronic infection. Wound infections are associated with alkaline pH due to the presence of bacteria, whereas creation of an acidic environment around the wound bed promotes faster healing. Herein, we develop injectable drug loaded nanoparticulate system of vancomycin encapsulated polycaprolactone nanoparticles coated with polyelectrolyte-Vitamin C in polyvinyl alcohol-alginate gel (D-PCL-PVc-PVA(Alg)...

OBJECTIVES: Trimethoprim/sulfamethoxazole (TMP/SMX) and clindamycin are frequently prescribed to treat cellulitis. The primary objective was to determine if weight-based dosing of these antibiotics is associated with better outcomes in cellulitis. The secondary objective was to assess variables associated with clinical failure among hospitalized patients with cellulitis with or without cutaneous abscess. METHODS: This multi-center retrospective cohort study was conducted from January 1, 2010 to September 4, 2014...

BACKGROUND: Post-operative antibiotics are often utilized for skin and soft tissue infection (SSTI) requiring surgical incision and drainage (I&D). We propose that antibiotics are unnecessary following I&D. METHODS: Patients aged 3months to 6years with SSTI of the buttocks, groin, thigh, and/or labia requiring I&D were prospectively enrolled. The primary outcome was the proportion of patients requiring re-drainage and/or antibiotics for SSTI recurrence, within 30days...

BACKGROUND: The "obesity paradox" has been demonstrated in chronic diseases but not in acute surgery. We sought to determine whether obesity is associated with improved outcomes in patients with severe soft tissue infections (SSTIs). METHODS: The 2006 to 2010 Nationwide Inpatient Sample was used to identify adult patients with SSTIs. Patients were categorized into nonobese and obese (nonmorbid [body mass index 30 to 39.9] and morbid [body mass index ≥ 40]). Logistic regression provided risk-adjusted association between obesity categories and inhospital mortality...

Escherichia coli, an intestinal Gram-negative bacterium, has been shown to be associated with a variety of diseases in addition to intestinal infections, such as urinary tract infections (UTIs), meningitis in neonates, septicemia, skin and soft tissue infections (SSTIs), and colisepticemia. Thus, for nonintestinal infections, it is categorized as extraintestinal pathogenic E. coli (ExPEC). It is also an opportunistic pathogen, causing cross infections, notably as an agent of zoonotic diseases. However, comparative genomic data providing functional and genetic coordinates for ExPEC strains associated with these different types of infections have not proven conclusive...

This study aimed to examine the epidemiology and treatment outcomes of community-onset purulent staphylococcal skin and soft tissue infections (SSTI) in Central Australia. We performed a prospective observational study of patients hospitalised with community-onset purulent staphylococcal SSTI (n = 160). Indigenous patients accounted for 78% of cases. Patients were predominantly young adults; however, there were high rates of co-morbid disease. Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) was the dominant phenotype, accounting for 60% of cases...

OBJECTIVES: Staphylococcus aureus skin and soft tissue infection (Sa-SSTI) places a significant burden on healthcare systems. New Zealand has a high incidence of Sa-SSTI, and here most morbidity is caused by a polyclonal methicillin-susceptible (MSSA) bacterial population. However, MSSA also colonise asymptomatically the cornified epithelia of approximately 20% of the population, and their divide between commensalism and pathogenicity is poorly understood. We aimed to see whether MSSA are genetically differentiated across colonisation and SSTI; and given the close interactions between people and pets, whether strains isolated from pets differ from human strains...

Skin and soft tissue infections (SSTIs) are among the most common health problems in travellers returning from tropical and subtropical countries. Importantly, the prevalence of Staphylococcus aureus, the most common pathogen for purulent SSTIs, with specific drug resistance, such as methicillin resistant Staphylococcus aureus (MRSA) and those expressing virulence genes, such as Panton-Valentine-leukocidin is higher in tropical regions than in most high resource settings. This poses challenges for the empirical antimicrobial treatment of SSTIs in returning travellers...

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA), a bacterial pathogen, is a predominant cause of skin and soft tissue infections (SSTI) in the United States. Swine-production facilities have been recognized as potential environmental reservoirs of MRSA. To better understand how swine production may contribute to MRSA infection, we evaluated the association between MRSA infection among SSTI inpatients and exposure measures derived from national swine inventory data. METHODS: Based on adjusted odds ratios from logistic regression models, we evaluated the association between swine exposure metrics and MRSA infections among all Illinois inpatient hospitalizations for SSTI from January 2008 through July 2011...

OBJECTIVES: Skin and soft tissue infections (SSTIs) are common among people who inject drugs (PWID), and can lead to serious morbidity and costly emergency room and hospital utilization. A range of high-risk injection practices may contribute to these infections. The goal of the current study was to examine risk practices that were associated with SSTIs in a sample of hospitalized PWID. METHODS: PWID (N = 143; 40.6% female) were recruited from inpatient medical units at a large urban hospital and completed a baseline interview that focused on infection risk...

Considerable technological advances, good safety profile, and ease of use have converged to support the use of ultrasound (US) as an important adjunct in the evaluation of superficial soft tissue infections (SSTI) in general and the differential diagnosis of cellulitis and abscess in particular. However, its use in neonatal populations has not been described. Pediatric studies report clinical examination is not always a reliable method of distinguishing cellulitis from abscess. Two (2) case reports are presented to supplement the growing body of published data that describe US imaging of SSTIs...
