To Come

Staphylococcus aureus continues to be a resilient and persistent problem for hospital infection control programs. Now methicillin-resistant S. aureus (MRSA) is emerging as an even more formidable foe, bringing with it controversies in laboratory reporting, treatment, and isolation strategies.History suggests that the best solution to the hospital bacteria problem may well lie in the realm of spirit more than material methods. So, in the manner of Dickens' Christmas Carol fantasy, let us travel with three spirits— the Spirit of Conscience Past, the Spirit of Conscience Present, and the Spirit of Conscience to Come.

Invasive Infections

The problem of methicillin resistant Staphylococcus aureus (MRSA) is increasing worldwide, and the spread of MRSA in the community challenges infection control since it is no longer restricted to hospital settings but involves private homes, places of work and kindergartens [1]. Furthermore, community acquired (CA)-MRSA may circumvent existing hospital infection control, since patients are rarely screened at admission. In the United States, the predominant CA-MRSA is defined by the Center for Disease Control (CDC) as the USA300 (ST8) clone. USA300 primarily causes skin and soft tissue infections (SSTI) in the community [2], but healthcare acquired infections with USA300 are rapidly emerging in the United States [3,4]. Comparison of the Danish collection of MRSA from 1997-2005 with the USA300 reference strain showed that USA300 has been introduced into Denmark on several occasions. Between 2000 and 2005, we identified 44 isolates which in addition to identical pulsed-field gel electrophoresis (PFGE) pattern shared other molecular characteristics with USA300: spa type t008 or closely related variants, Panton-Valentine leukocidin (PVL) positive and Staphylococcal Cassette Chromosome mec (SCCmec) type IVa. The isolates primarily caused SSTI, but cases of invasive infections were also encountered. The number of USA300 has increased several-folds in Denmark from 2003 to 2005 (2, 11 and 28 new cases, respectively) and with the experience from the US in mind, this is of great concern, especially as it is observed in a country with a long reputation for controlling MRSA.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of healthcare-associated infections. To combat the challenge of life threatening MRSA remains a primary focus of most hospital infection control programs6. This study is undertaken in Khwaja Yunus Ali Medical College Hospital to identify the MRSA for determination of its prevalence and is considered a component of an infection control program in many countries5.Methods: Three hundred seventy hospitalized patients of surgery and medicine departments were studied during 2015. Clinical information of the patients and their pus, wound swab, sputum, throat swab and CSF were cultured.Results: Out of 370 patients, pus and wound swab of 217 (59%) had wound infection, sputum and throat swab of 141 had respiratory tract infection (38%) and CSF of 12 (3.2%) had meningitis were aseptically collected and cultured. Staphylococcus aureus were isolated in 51% cases and out of them MRSA was identified in 72 (73%) cases. MRSA isolated in 50% cases of meningitis, 49% cases of respiratory tract infection and 29% cases of wound infection.Conclusion: Methicillin-resistant Staphylococcus aureus appeared as a common cause of major illness and death and impose serious economic costs on patients and hospitals of our area like other developing countries. Detection of MRSA was associated with more severe clinical presentation.KYAMC Journal Vol. 7, No.-1, Jul 2016, Page 673-677

Mrsa Strains

Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most complicated problems in infection control and disease prevention. Imported strains or group of similar strains called clones were introduced from other states within Australia and also from other countries. Western Australia (WA) MRSA clones known to be the most predominant clones circulating in Western Australia (WA). However, MRSA strains originally from other states and countries outside Australia (imported) have increased in number in the last decades. The aim of this study was to examine the epidemiology of CA MRSA clones in Western Australia for the past 11 year’s period (2003-2013). There were 10 predominant clones of CA-MRSA circulating in WA with WA MRSA-1 (32,82%), Queensland (22,67 %) and WA MRSA-2 (22,67 %) clones as the top three predominant clones. The percentage of PVL positive CA-MRSA clones such as Queensland (Qld) clone has been increasing significantly (R2=0,67) from 2,38 % in 2002 to 25,69% in 2013. In contrast, the percentages of two major PVL negative clones, WA MRSA-1 and WA MRSA 2, have been decreasing nearly by half from 52,38 % to 27,71 % and 30,95 % to 16,59 % respectively in the last 11 years. PVL positive clones have been introduced in WA from other states and overseas in the last eleven years. Due to the virulence factor of PVL toxin, the emergence of PVL positive CA-MRSA should be considered as public health concerns.
