Environmental methicillin-resistant Staphylococcus aureus contamination, persistent colonization, and subsequent skin and soft tissue infection.
This 12-month prospective cohort study examined households contaminated with methicillin-resistant Staphylococcus aureus (MRSA), persistent colonization, and subsequent soft tissue infection (SSTI). Households in St. Louis who had members with community-acquired MRSA SSTI were longitudinally tracked from 2012 to 2015. A baseline visit was conducted at the index patient’s primary home, followed by four quarterly visits over 12 months. With each visit, an interview and serial cultures were collected. Of the 692 participants in 150 households, including 150 children, who completed all 5 samplings; 213 (39%) showed persistent colonization with S. aureus, particularly in the nose. Nine pets (8%) were persistently colonized with S. aureus. Interval SSTI was also associated with MRSA in 76 index patients (53%) and 101 household contacts (19%).

Longitudinal, strain-specific Staphylococcus aureus introduction and transmission events in households of children with community-associated meticillin-resistant S aureus skin and soft tissue infection: a prospective cohort study.
This prospective cohort study examined methods of transmission for methicillin-resistant Staphylococcus aureus (MRSA) in households with otherwise healthy children who have a MRSA infection. From 2012-2015 households in St. Louis with children who had a community-acquired MRSA skin and soft-tissue infection were longitudinally tracked. Children with other health issues were excluded. A baseline visit was conducted at the index patient’s primary home, followed by four quarterly visits over 12 months. With each visit, an interview and serial cultures were collected. Molecular typing was done of those samples to determine the distinct S aureus strain. MRSA recipients were most likely to live in a rental situation, and were more likely to share a bedroom with a strain-colonised individual. The most likely transmission source was shared bath towels. Pets were often recipients, but rarely the sole transmission source. Frequent handwashing decreased the likelihood of novel strains being introduced into the house and emphasizes the importance of hand hygiene.

Prevalence of staphylococcus aureus and use of antistaphylococcal therapy in children hospitalized with pneumonia.
In a studied group of children hospitalized with community-acquired pneumonia, staphylococcal pneumonia was rare but associated with adverse in-hospital outcomes. Despite this low prevalence, use of antistaphylococcal antibiotics was common. The authors recommended efforts to minimize overuse of antistaphylococcal antibiotics while also ensuring adequate treatment for pathogen-specific diseases.

Methicillin-resistant staphylococcus aureus: the effects are more than skin deep.
The purpose of the study was to assess the psychosocial effects of a methicillin-resistant Staphylococcus aureus (MRSA) diagnosis on the households of children with MRSA skin and soft tissue infection (SSTI). The study found that primary caregivers of children with MRSA SSTI reported changing their health behaviors, altering their interactions with people outside of their home, and feeling isolated by others in response to their child's MRSA diagnosis.

Comparison of empiric antibiotics for acute osteomyelitis in children.
Broad-spectrum antibiotics are commonly used for the empiric treatment of acute hematogenous osteomyelitis and often target methicillin-resistant Staphylococcus aureus (MRSA) with medication-associated risk and unknown treatment benefit. In this study, the investigators aimed to compare clinical outcomes among patients with osteomyelitis who did and did not receive initial antibiotics used to target MRSA. The investigators found that, early antibiotic treatment used to target MRSA was associated with a higher rate of repeat MRI.

Antimicrobial susceptibility profiles of Staphylococcus aureus isolates recovered from humans, environmental surfaces, and companion animals in households of children with community-onset Methicillin-Resistant S. aureus infections.
The study objective was to determine the antibiotic susceptibility profiles of Staphylococcus aureus isolates recovered from 110 households of children with community-onset methicillin-resistant S. aureus (MRSA) infections. It found that the S. aureus isolates were heterogeneous, although more than half were methicillin resistant. The highest proportion of MRSA was found in bathrooms.

Decolonization of children after incision and drainage for MRSA abscess: a retrospective cohort study.
The researchers sought to determine whether decolonization following incision and drainage (I&D) for methicillin-resistant Staphylococcus aureus (MRSA) abscess decreases repeat I&D and MRSA-positive cultures in children. They found that no statistically significant association between referral to the Pediatric Infectious Disease Service for decolonization and the outcomes.

Contamination of environmental surfaces with Staphylococcus aureus in households with children infected with methicillin-resistant S aureus.
This study of the households of 50 children with active or recent culture-positive community-associated methicillin-resistant staphylococcus aureus (MRSA) infection found MRSA-contaminated surfaces in 23 of the 50 households, most frequently form the bed linens (18 percent), television remote control (16 percent), and bathroom hand towel (15 percent).
