Methicillin-Resistant Staphylococcus aureus in a Beauty Salon, the Netherlands

An outbreak of community-associated USA300 methicillin-resistant Staphylococcus aureus occurred in a beautician and 2 of her customers. Eight other persons, who were either infected (n = 5) or colonized (n = 3), were linked to this outbreak, including a family member, a household contact, and partners of customers

Staphylococcus aureus ST398, New York City and Dominican Republic

Closely related Staphylococcus aureus strains of ST398, an animal-associated strain, were identified in samples collected from humans in northern Manhattan, New York, NY, USA, and in the Dominican Republic. A large population in northern Manhattan has close ties to the Dominican Republic, suggesting international transmission

Prenatal diagnosis of a trisomy 7/trisomy 13 mosaicism

Double aneuploidy mosaicism of two different aneuploidy cell lines is rare. We describe for the first time a double trisomy mosaicism, involving chromosomes 7 and 13 in a fetus presenting with multiple congenital anomalies. No evidence for chimerism was found by DNA genotyping. The origin of both trisomies are consistent with isodisomy of maternal origin. Therefore, it is most likely that the double trisomy mosaicism arose from two independent events very early in embryonic development. The trisomy 7 and 13 cells were shown to be of maternal origin

Methicillin-resistant Staphylococcus aureus in Dutch Soccer Team

An outbreak of community-acquired methicillin-resistant Staphylococcus aureus occurred among members and close contacts of a soccer team. Typing of the isolates showed the outbreak was caused by the well-known European ST80-IV strain. To our knowledge, this is the first report of an outbreak of this strain among members of a sports team

PFGE diversity within the methicillin-resistant Staphylococcus aureus clonal lineage ST398

<p>Abstract</p> <p>Background</p> <p>Livestock has recently been identified as a new reservoir of methicillin-resistant <it>Staphylococcus aureus </it>(MRSA). Most isolates belong to ST398 and are non-typeable with PFGE using <it>Sma</it>I, making it difficult to study transmission and outbreaks. Therefore, a new PFGE using <it>Cfr</it>9I, a neoschizomer of <it>Sma</it>I was optimized and evaluated to investigate ST398 isolates.</p> <p>Results</p> <p>After optimizing and evaluating the <it>Cfr</it>9I PFGE, clear and reproducible banding patterns were obtained from all previously non-typeable MRSA (NT_{<it>Sma</it>I}-MRSA) isolates. The PFGE patterns of ST398 isolates showed more diversity than with <it>spa</it>-typing and/or MLST. The PFGE results showed diversity within and between the two most prevalent <it>spa</it>-types of NT_{<it>Sma</it>I}-MRSA (t011 and t108). No match was found, when comparing banding patterns of the NT_{<it>Sma</it>I}-MRSA with 700 different PFGE types, obtained with <it>Sma</it>I digestion, in our database of more than 4000 strains. Furthermore, possible transmission among veterinarians and their family members was investigated and an outbreak of ST398 MRSA in a residential care facility was confirmed with the <it>Cfr</it>9I PFGE.</p> <p>Conclusions</p> <p>The adjusted PFGE can be used as a method for selecting important and distinct ST398 isolates for further research. The adjustments in the PFGE protocol using <it>Cfr</it>9I are easy to implement to study the ST398 clonal lineage in laboratories which already have a PFGE facility.</p

Methicillin-Resistant Staphylococcus aureus in Poultry

Methicillin-resistant Staphylococcus aureus (MRSA) has been detected in several species and animal-derived products. To determine whether MRSA is present in poultry, we sampled 50 laying hens and 75 broiler chickens. MRSA was found in some broiler chickens but no laying hens. In all samples, spa type t1456 was found

Methicillin-Resistant and -Susceptible Staphylococcus aureus Sequence Type 398 in Pigs and Humans

Methicillin-resistant Staphylococcus aureus sequence type 398 (ST398 MRSA) was identified in Dutch pigs and pig farmers. ST398 methicillin-susceptible S. aureus circulates among humans at low frequency (0.2%) but was isolated in 3 human cases of bacteremia (2.1%; p = 0.026). Although its natural host is probably porcine, ST398 MRSA likely causes infections in humans
