High clonal diversity of Staphylococcus aureus isolates from children's playgrounds in Hungary.

Staphylococcus aureus is one of the most important human pathogenic bacteria and environmental surfaces play an important role in the spread of the bacterium. Presence of S. aureus on children's playgrounds and on toys was described in international studies, however, little is known about the prevalence and characteristics of S.

Prevalence, serogroup distribution and risk factors of Neisseria meningitidis carriage in high school and university students in Hungary.

Neisseria meningitidis causes life-threatening invasive meningococcal disease (IMD) with high mortality worldwide. Asymptomatic pharyngeal meningococcus colonisation is an important reservoir for the spread of the bacterium. The aim of this study was to determine N.

Genomic Evidence for Direct Transmission of -MRSA between a Horse and Its Veterinarian.

Methicillin-resistant bearing the gene (-MRSA) has been reported from animals and humans in recent years. This study describes the first -MRSA isolates of human and equine origin in Hungary (two isolates from horses and one from a veterinarian, who treated one of the infected horses, but was asymptomatic). MRSA isolates were identified by cultivation and PCR detection of the species-specific gene and / methicillin resistance genes.

Prevalence of Staphylococcus aureus in wild hedgehogs (Erinaceus europaeus) and first report of mecC-MRSA in Hungary.

In 2011 mecC, a new mecA gene homologue, was described in a bovine isolate in the UK. Since then, mecC-positive methicillin-resistant Staphylococcus aureus (mecC-MRSA) has also been found in wild animals. An especially high prevalence of mecC-MRSA has been reported among hedgehogs in Sweden (64%) and Denmark (61%).

Whole genome sequencing of coagulase positive staphylococci from a dog-and-owner screening survey.

Background: Staphylococcus aureus and S. pseudintermedius are the two most common coagulase positive staphylococci (CPS). S.

Co-carriage of Staphylococcus aureus, Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis among three different age categories of children in Hungary.

Background: The nasopharynx can from time to time accommodate otherwise pathogenic bacteria. This phenomenon is called asymptomatic carriage. However, in case of decreased immunity, viral infection or any other enhancing factors, severe disease can develop.

Vaccine-driven serotype-rearrangement is seen with latency in clinical isolates: Comparison of carried and clinical pneumococcal isolates from the same time period in Hungary.

Young children - the main asymptomatic carriers of pneumococcus - are often the source of pneumococcal infections. PCV13 replaced PCV7 in 2010 in Hungary and it became a mandatory vaccine in 2014. In this work we surveyed the effect of vaccination in three groups: in healthy children under 7 years; in children of the same age but infected with pneumococcus (P1); in older patients (P2) who were very likely not vaccinated.

High prevalence of Staphylococcus aureus nasal carriage among children in Szolnok, Hungary.

We collected nasal samples from 1,390 healthy 3-7 years old children in Szolnok city, Hungary, in 2012. We detected 476 Staphylococcus aureus isolates from 474 children. In two occasions, two different S.
