Pig movement and antimicrobial use drive transmission of livestock-associated staphylococcus aureus CC398.
Staphylococcus aureus was originally considered a hospital-associated organism, but new classes of methicillin-resistant strains have emerged outside of the hospital setting, including among livestock. This article discusses a recent study which examined the transportation of pigs on over 200 farms; the authors of this article contend that the results of the study demonstrate the importance of cooperation between occupational health services, genomics, veterinary medicine, and farmers in understanding the epidemiology of MRSAs as related to livestock.

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.

Comprehensive modeling reveals proximity, seasonality, and hygiene practices as key determinants of MRSA colonization in exposed households.
To develop interventions to prevent recurrent infections, household attributes and individual practices influencing S. aureus colonization must be discerned. In this paper, the investigators discuss key determinants of methicillin-resistant S. aureus (MRSA) colonization in exposed households. They suggest that the practices they identified in their study, that correlate with MRSA colonization, will inform physician counseling and multifaceted interventions among MRSA-affected households to mitigate MRSA in the community.

Spatial relationships among public places frequented by families plagued by methicillin-resistant Staphylococcus aureus.
In this study, the investigators mapped public places (including personal service establishments, fitness centers, pools, schools, and daycares) visited by members of households affected by community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) skin and soft tissue infection, in order to understand factors associated with CA-MRSA acquisition and infection.

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.

Whole-genome analysis of recurrent Staphylococcus aureus t571/ST398 infection in farmer, Iowa, USA.
Staphylococcus aureus strain sequence type (ST) 398 has emerged during the last decade, largely among persons who have contact with swine or other livestock. Although colonization with ST398 is common in livestock workers, infections are not frequently documented. The authors report recurrent ST398-IIa infection in an Iowa farmer in contact with swine and cattle.

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).

Does chlorhexidine bathing in adult intensive care units reduce blood culture contamination? A pragmatic cluster-randomized trial.
The investigators determined rates of blood culture contamination comparing 3 strategies to prevent intensive care unit (ICU) infections: screening and isolation, targeted decolonization, and universal decolonization. They demonstrated that universal decolonization with mupirocin and chlorhexidine bathing resulted in a significant reduction in blood culture contamination.

Resistance to zinc and cadmium in Staphylococcus aureus of human and animal origin.
The investigators determined the prevalence of zinc and cadmium resistance in S. aureus isolated in the United States. They found that resistance to zinc and cadmium was observed to be associated with MRSA, suggesting that prolonged exposure to zinc in livestock feeds and fertilizers could propagate resistance to the metal ion, hindering the use of zinc-based topical agents in treating S. aureus infections.

Performance of the Cepheid Xpert(R) SA Nasal Complete PCR assay compared to culture for detection of methicillin-sensitive and methicillin-resistant Staphylococcus aureus colonization.
Conventional culture-based methods, including several chromogenic agars, are available for SA and MRSA surveillance but they can take several days and have reduced sensitivity compared to amplification assays. Overall, the Cepheid assay proved a rapid, sensitive, and clinically useful test for the early detection and differentiation of MRSA and MSSA colonization on patients.

Preventing the transmission of multidrug-resistant organisms: modeling the relative importance of hand hygiene and environmental cleaning interventions.
The authors investigated the relative impact of hand hygiene and environmental cleaning in order to assess resource allocation. They concluded that hand hygiene should remain a priority for infection control programs, but environmental cleaning can have significant benefit for hospitals or individual hospital units that have either high hand hygiene compliance levels or low terminal cleaning thoroughness.
