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.

Clinical and microbiological characteristics of adult invasive Haemophilus influenzae infections: results of a 14-year single-center experience from Hungary.

To describe the characteristics of adult invasive H. influenzae disease, 34 patients diagnosed at a single tertiary center between 2004 and 2017 were analyzed in a retrospective case series study. The annual estimated incidence was 0.

First description of a rifampicin-resistant Neisseria meningitidis serogroup Y strain causing recurrent invasive meningococcal disease in Hungary.

A Hungarian soldier previously immunized against Neisseria meningitidis by quadrivalent polysaccharide vaccine was twice infected with meningococci within six weeks. The patient was treated with ceftriaxone during both episodes and he successfully recovered. His close contacts received rifampicin prophylaxis.

Radical serotype rearrangement of carried pneumococci in the first 3 years after intensive vaccination started in Hungary.

Unlabelled: Streptococcus pneumoniae is responsible for a significant amount of morbidity and mortality worldwide. Healthy carriers, mainly young children, are the most important sources of infections. In the current study, we aimed to determine the changes that have occurred since the introduction of PCV-7 in Hungary.

Listeria monocytogenes food monitoring data and incidence of human listeriosis in Hungary, 2004.

Food samples were monitored for contamination with Listeria monocytogenes, and the incidence of human listeriosis was evaluated according to the data obtained in Hungary in the year 2004. Of the food samples tested, the bacterium was most often detectable in milk and dairy products, as 72.1% of all L.
