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.

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.

Burden of invasive staphylococcus aureus infections in hospitalized infants.
This study compared demographics and mortality of inf ants with invasive methicillin-resistant S aureus (MRSA) and methicillin-susceptible S aureus (MSSA), to determine the annual proportion of S aureus infections that were MRSA. It found that infant mortality after invasive MRSA and MSSA infections was similar, but MSSA caused more infections and more deaths in infants than MRSA.

Nonimpact of decolonization as an adjunctive measure to contact precautions for the control of methicillin-resistant Staphylococcus aureus transmission in acute care.
This was an observational study comparing methicillin-resistant Staphylococcus aureus (MRSA) transmission with no decolonization of medical patients to required decolonization of all MRSA carriers during two consecutive periods: baseline with no decolonization of medical patients and universal MRSA carrier decolonization. The study concluded that decolonization of MRSA patients does not add benefit when contact precautions are used for patients colonized with MRSA in acute (hospital) care.

Application of a methicillin-resistant Staphylococcus aureus risk score for community-onset pneumonia patients and outcomes with initial treatment.
The study objective was to assess the effect of initial MRSA therapy on mortality in community–onset (CO) pneumonia patients that a new MRSA prediction score had classified into low, medium, and high-risk groups based on objective criteria available at baseline. The study demonstrated improved survival with initial MRSA therapy in the 2 percent of CO-pneumonia patients classified as high-risk.

Prevention of recurrent staphylococcal skin infections.
Staphylococcus aureus infections pose a significant health burden. As S aureus colonization is associated with subsequent infection, decolonization is recommended for patients with recurrent skin and soft tissue infections or in settings of ongoing transmission. S aureus infections often cluster within households, and asymptomatic carriers serve as reservoirs for transmission; therefore, a household approach to decolonization is more effective than measures performed by individuals alone.

Transmission of methicillin-resistant Staphylococcus aureus (MRSA) to healthcare worker gowns and gloves during care of nursing home residents.
This study estimated the frequency of methicillin-resistant Staphylococcus aureus (MRSA) transmission to gowns and gloves worn by healthcare workers (HCWs) interacting with nursing home residents to better inform infection prevention policies in this setting. It found that MRSA transmission from MRSA-positive residents to health care worker gown and gloves is substantial; high-contact activities of daily living confer the highest risk.

Molecular types of methicillin-resistant staphylococcus aureus and methicillin-sensitive S. aureus strains causing skin and soft tissue infections and nasal colonization, identified in community health centers in New York City.
In November 2011, a research and learning collaborative project with six community health centers in the New York City metropolitan area was launched to determine the nature (clonal type) of community-acquired Staphylococcus aureus strains causing skin and soft tissue infections (SSTIs). It found that of 63 patients with S. aureus infections, 16 of the colonizing isolates were MRSA, and 14 were MSSA, and the majority of the colonizing isolates belonged to the USA300 clonal group.

Swine farming is a risk factor for infection with and high prevalence of carriage of multidrug-resistant Staphylococcus aureus.
The researchers conducted a large-scale prospective study of 1,342 Iowans, including individuals with livestock contact and a community-based comparison group. They found that current swine workers are 6 times more likely to carry multidrug-resistant S. aureus than those without current swine exposure. Also, they observed active infections caused by livestock-associated S. aureus.

Recurrent furunculosis caused by a community-acquired Staphylococcus aureus strain belonging to the USA300 clone.
This study is a clinical history of a patient with recurrent skin infections caused by a strain of CA-MRSA belonging to the USA300 clone. The strain was recovered repeatedly from wounds and lower body sites but never from the nostrils. The clinical history of recurrence strongly suggests the existence of a common environmental source of the MRSA strain.

Infection control precautions for visitors to healthcare facilities.
Infection transmission in healthcare facilities is a growing concern. Visitation to healthcare facilities is very common, though the potential role of visitors in the transmission of infection is unknown. Decisions regarding whether to implement transmission-based precautions among visitors should take into account the organism of concern and means of transmission as well as factors pertaining to the visitor and the healthcare setting.

Screening for methicillin-resistant Staphylococcus aureus colonization using sponges.
The researchers investigated whether the additional use of a sponge to collect skin culture samples would significantly improve the sensitivity of MRSA detection. They found that the sensitivity of nasal swab culture for screening MRSA carriage is low, but it can be improved significantly by adding a second method, either sampling the skin or the pharynx.
