Methicillin resistant Staphylococcus aureus outbreak in a neonatal intensive care unit.

This study reports an MRSA outbreak in a level-II neonatal intensive care unit (NICU) of a secondary care hospital in Pakistan. Once identified, an infection control team from the parent hospital visited the facility, risk factors were listed and infection control measures taken to control the outbreak. Screening cultures of NICU staff and environmental cultures from NICU were obtained for the presence of MRSA. Five neonates were positive for MRSA; one HCW was found to be colonized with MRSA, the antibiogram pattern of which matched with that of the outbreak strain. Decolonization of colonized HCWs and re-deployment from NICU to outpatient department were taken and the outbreak was declared over once no further MRSA cases were identified. Identification of an outbreak situation is the cornerstone for its control and multiple measures taken simultaneously help in curbing the outbreak. Although an epidemiological link was established with the HCW, a molecular link could not be proven. PMID: 31612983 [PubMed - in process]

Abstract To study pathogenesis and toxicity of Staphylococcus aureus in foods, FORC_062 was isolated from a human blood sample and complete genome sequence has a type II SCCmec gene cluster and a type II toxin-antitoxin system, indicating an MRSA strain. Its mobile gene elements has many pathogenic genes involved in host infection, biofilm formation, and various enterotoxin and hemolysin genes. Clinical MRSA is often found in animal foods and ingestion of MRSA-contaminated foods causes human infection. Therefore, it is very important to understand the role of contaminated foods. To elucidate the interaction betwee...

ConclusionOur results reveal the radiation of distinct lineages of MRSA ST228 from a German progenitor, as the clone spread into different European countries. In Switzerland, ST228 was introduced first in Geneva and was subsequently introduced into Lausanne.

Staphylococcus aureus is a leading cause for clinical infections and food intoxications, causing over 100,000 yearly cases of bacteremia in the United States and 434 food-borne outbreaks in the European Union. Approximately 30% of the population permanently carry S. aureus asymptomatically in their nasal cavity. The risk of infection and transmission to food items or the environment is higher in individuals that are nasally colonized. In addition, S. aureus can acquire various antimicrobial resistances leading to therapeutic failure, additional medical costs, and fatalities. Methicillin-resistant S. aureus (MRSA) cause a c...

CONCLUSIONS: Although MRSA has a low prevalence in our center, a variation in the rate of MRSA positivity was observed across patients from different countries. Absence hospital acquired contamination or outbreaks in our institution may be attributed to the screening algorithm used and underscores the importance of risk analysis for patients referred from geographical locations with unknown MRSA frequency, to reduce the risk of transmission.

This article summarizes the available evidence enabling a stratification of risk for multidrug-resistant bacteria (MDRB) in patients with skin and soft tissue infection (SSTI). Recent findings MDRB are increasingly reported in both healthcare-associated (HCA) and community-acquired (CA)-SSTI, including in patients with life-threatening presentations for whom early initiation of adequate antimicrobial therapy is pivotal to improve outcomes. Community-associated methicillin-resistant Staphylococcus aureus (MRSA) is now endemic in several geographical areas and may cause outbreaks in frail populations or other at-risk clus...

AbstractThe incidence of methicillin-resistantStaphylococcus aureus (MRSA) has increased sharply in Hospital District of Southwest Finland (HD). To understand reasons behind this, a retrospective, population-based study covering 10  years was conducted. All new 983 MRSA cases in HD from January 2007 to December 2016 were analysed. Several data sources were used to gather background information on the cases. MRSA cases were classified as healthcare-associated (HA-MRSA), community-associated (CA-MRSA), and livestock contact was determined (livestock-associated MRSA, LA-MRSA).Spa typing was performed to all available str...

ConclusionLA-MRSA CC398 is transmittable in hospitals, and intervention against transmission may reach considerable costs. CgMLST is useful in surveillance of hospital transmission of LA-MRSA.

In this study, we established a long-read technology-based WGS screening program of all first-episode methicillin-resistant Staphylococcus aureus (MRSA) blood infections at a major urban hospital. A survey of 132 MRSA genomes assembled from long reads enabled detailed characterization of an outbreak lasting several months of a CC5/ST105/USA100 clone among 18 infants in a neonatal intensive care unit (NICU). Available hospital-wide genome surveillance data traced the origins of the outbreak to three patients admitted to adult wards during a 4-month period preceding the NICU outbreak. The pattern of changes among complete ou...

ConclusionInfection prevention and control practices regarding active pathogen surveillance cultures and the use of barrier precautions varied widely in Japanese neonatal units. National guidelines and evidence-based recommendations are needed to rationalize and standardize current infection prevention and control practices in neonatal units in Japan.
